Description

車両用メニュー表示制御装置、車載機器操作システム、及びＧＵＩプログラムVEHICLE MENU DISPLAY CONTROL DEVICE, IN-VEHICLE DEVICE OPERATION SYSTEM, AND GUI PROGRAM
　本発明は、例えば、自動車等の車両に搭載される車両用メニュー表示制御装置、車載機器操作システム、及びＧＵＩプログラム等に関する。 The present invention relates to a vehicle menu display control device mounted on a vehicle such as an automobile, an in-vehicle device operation system, a GUI program, and the like.
　ハンドルを握って車両を運転しているユーザ（運転者）は、前方を注視しつつ、ブラインドタッチで車両用のポインティングデバイスを直観的に操作し、メニュー画像を表示させ、極めて短時間でメニュー項目を選択する必要がある。したがって、例えば、デスクトップパソコン等で、マウス等のポインティングデバイスを用いてメニュー画像を選択する場合に比べて、精度あるいはポインティングデバイスの操作速度の点で劣るのはやむを得ない。したがって、車載機器を操作する際に、冗長な操作が極力生じないように配慮することが望まれる。 A user (driver) who is driving the vehicle while holding the steering wheel, intuitively operates the pointing device for the vehicle with a blind touch while gazing at the front, and displays the menu image. It is necessary to select. Therefore, for example, it is inevitable that the accuracy or the operation speed of the pointing device is inferior to the case where a menu image is selected using a pointing device such as a mouse on a desktop personal computer or the like. Therefore, it is desirable to take care to avoid redundant operations as much as possible when operating on-vehicle equipment.
　このため、例えば、特許文献１に、ヘッドアップディスプレイ（ＨＵＤ）等の表示装置に表示された車載機器のメニュー項目を示すラジアル操作メニューを、ポインティングデバイスによりユーザがブラインド操作で選択できるようにした車載機器操作システムが提案されている。 For this reason, for example, in Japanese Patent Application Laid-Open No. H10-228867, a user can select a radial operation menu indicating a menu item of an in-vehicle device displayed on a display device such as a head-up display (HUD) by a blind operation by a pointing device. Equipment operation systems have been proposed.
特開２０１５－９３５５０号公報Japanese Patent Laid-Open No. 2015-93550
　ここで、ラジアル操作メニューとは、円の中心を基点に半径方向に延びる２本の線と、この２本の線の間の円弧で囲まれた部分円（以下、セクタ領域ともいう）のそれぞれにメニュー項目を割り当てたメニュー形式である。このラジアル操作メニューの中に、階層構造を有するメニュー項目が割り当てられていた場合、例えば、ｎ階層（ｎは２以上の整数）に属するメニュー項目から１つのメニュー項目が指定され、その選択（決定）操作がなされると、選択されたメニュー項目に対応するｎ＋１階層に属する新たなメニュー項目が階層展開されて表示される。 Here, the radial operation menu includes two lines extending radially from the center of the circle and a partial circle (hereinafter also referred to as a sector area) surrounded by an arc between the two lines. This is a menu format in which menu items are assigned to. When a menu item having a hierarchical structure is assigned in the radial operation menu, for example, one menu item is designated from the menu items belonging to the n hierarchy (n is an integer of 2 or more), and the selection (determination) is performed. When an operation is performed, a new menu item belonging to the (n + 1) th hierarchy corresponding to the selected menu item is expanded and displayed.
　すなわち、ユーザ（運転者）は、ｎ階層のメニュー項目を指定操作する前に、対応するｎ＋１階層のメニュー項目を確認することがでない。言い換えると、ユーザは、階層構造を有するラジアル操作メニューの１つを指定する段階で、下位階層のメニュー項目の中に目的とするメニュー項目があるか否かを確認することはできない。上位階層のメニュー項目を選択（決定）操作した段階で表示される下位階層のメニュー項目を確認して、はじめて下位階層に目的とするメニュー項目があるか否かを知ることができる。このため、目的とするメニュー項目に辿り着くまでに冗長な操作を必要とし、目的とするメニュー項目に迅速に辿り着くことができない、といった不都合があった。 That is, the user (driver) does not check the corresponding menu item of the (n + 1) layer before performing the designation operation of the menu item of the n layer. In other words, the user cannot confirm whether there is a target menu item among the menu items in the lower hierarchy at the stage of designating one of the radial operation menus having a hierarchical structure. By checking the menu item of the lower layer displayed when the menu item of the upper layer is selected (determined), it is possible to know whether or not the target menu item exists in the lower layer for the first time. For this reason, there is an inconvenience that a redundant operation is required until the target menu item is reached, and the target menu item cannot be quickly reached.
　本発明は、上記した課題に着目してなされたものであり、上位階層のメニュー項目の選択（決定）操作前に、対応する下位階層のメニュー項目を確認できるＧＵＩ環境を提供することにより、冗長な操作を省き、目的とするメニュー項目に迅速に辿り着くことができる、車両用メニュー表示制御装置、車載機器操作システム、及びＧＵＩプログラムを提供することを目的とする。 The present invention has been made paying attention to the above-described problems, and provides a GUI environment in which a corresponding menu item in a lower hierarchy can be confirmed before a selection (determination) operation of the menu item in an upper hierarchy, thereby providing redundancy. An object of the present invention is to provide a vehicular menu display control device, an in-vehicle device operation system, and a GUI program that can quickly reach a target menu item.
　本発明の他の目的は、以下に例示する態様及び最良の実施形態、並びに添付の図面を参照することによって、当業者に明らかになるであろう。 Other objects of the present invention will become apparent to those skilled in the art by referring to the aspects and best embodiments exemplified below and the accompanying drawings.

When the first partial circle is designated, second partial circles to which one or more menu items belonging to the n + 1 hierarchy corresponding to one of the designated menu items are assigned are respectively generated, and the generated second partial circle is generated. Each of the partial circles is arranged on the outer circumference of the designated first partial circle to generate an image of the updated radial operation menu, and the display control means includes the first image included in the updated radial operation menu image. Control is performed to display each of the two partial circles on the outer periphery of the designated first partial circle.
　このため、第１の態様によれば、車両用メニュー表示制御装置は、指定されたｎ階層のメニュー項目が割り当てられた第１の部分円の周辺に、指定されたメニュー項目の一つに対応するｎ＋１階層に属する１以上のメニュー項目を割り当てた第２の部分円を表示するＧＵＩ環境を提供することができる。このため、ユーザ（運転者）は、ｎ階層のメニュー項目を選択（決定）操作する前に、指定されたｎ階層に属するメニュー項目に対応するｎ＋１階層のメニュー項目を確認することができる。したがって、ユーザは、目的とするｎ＋１階層のメニュー項目に至るまでに階層毎に対応するメニュー項目を表示して選択（決定）するという、従来の冗長な操作を行う必要がない。 For this reason, according to the first aspect, the vehicle menu display control device corresponds to one of the designated menu items around the first partial circle to which the designated n-level menu item is assigned. It is possible to provide a GUI environment for displaying a second partial circle to which one or more menu items belonging to the (n + 1) layer are assigned. For this reason, the user (driver) can confirm the menu item of the n + 1 hierarchy corresponding to the menu item which belongs to the designated n hierarchy, before selecting (deciding) the menu item of the n hierarchy. Therefore, the user does not need to perform the conventional redundant operation of displaying and selecting (determining) the menu item corresponding to each hierarchy before reaching the target menu item of the (n + 1) th hierarchy.
　言い換えると、車両用メニュー表示制御装置が、目的とするメニュー項目が含まれる下位階層のメニュー項目を、指定された上位階層のメニュー項目が割り当てられた部分円の外周に配置して表示させる制御を行うことで、ユーザは、下位階層のメニュー項目の中に、直接的（かつ直観的）に目的とするメニュー項目があるか否かを知ることができ、そのメニュー項目を選択（決定）操作することができる。したがって、迅速で効率的なメニュー項目の選択が可能になり、操作性や使い勝手の向上を図ることができる。 In other words, control for causing the vehicle menu display control device to display the lower-level menu item including the target menu item by placing it on the outer periphery of the partial circle to which the specified higher-level menu item is assigned. By doing so, the user can know whether or not the target menu item is directly (and intuitively) in the lower-level menu items, and selects (determines) the menu item. be able to. Therefore, menu items can be selected quickly and efficiently, and operability and usability can be improved.
　ここで、「指定」とは、ユーザが、操作入力装置の操作面を触れるかなぞるユーザ操作をいい、「選択（決定）」とは、操作入力装置の操作面を押下するユーザ操作をいう。また、「外周」とは、ｎ階層のメニュー項目のそれぞれが割り当てられる部分円の集合である円よりも大きな半径を有し、指定された部分円と向かい合う同心円の領域中の一部領域のことをいう。 Here, “designation” refers to a user operation in which the user touches the operation surface of the operation input device, and “selection (decision)” refers to a user operation to press the operation surface of the operation input device. The “periphery” is a partial area in a concentric circle area that has a larger radius than a circle that is a set of partial circles to which each n-level menu item is assigned and faces a specified partial circle. Say.
　また、第１の態様に従属する第２の態様において、
　前記表示制御手段は、
　前記第２の部分円のそれぞれを、前記第１の部分円の表示位置を基準に時計回りか反時計回りの方向の前記第１の部分円の外周に表示する制御を行う。 In a second aspect subordinate to the first aspect,
The display control means includes
Control is performed to display each of the second partial circles on the outer periphery of the first partial circle in a clockwise or counterclockwise direction with reference to the display position of the first partial circle.
　第２の態様によれば、表示制御手段が、第２の部分円のそれぞれを、第１の部分円の表示位置を基準に時計回りか反時計回りの方向の第１の部分円の外周に表示する。言い換えれば、指定された第１の部分円の外周には、指定された部分円に割り当てたメニュー項目に対応する第２の部分円のみを時計回りか半時計回り方向に表示し、指定されていない部分円に割り当てたメニュー項目に対応する第２の部分円は表示されない。このため、第２の態様によれば、選択した第１の部分円を基準に、時計回り又は反時計回りの方向に対応する第２の部分円のそれぞれが表示されるため、ユーザ（運転者）は、外周に表示された第２の部分円に割り当てたそれぞれメニュー項目が、指定された第１の部分円のどのメニュー項目に対応しているかを認識することが容易になる。 According to the second aspect, the display control means places each of the second partial circles on the outer circumference of the first partial circle in the clockwise or counterclockwise direction with reference to the display position of the first partial circle. indicate. In other words, on the outer periphery of the designated first partial circle, only the second partial circle corresponding to the menu item assigned to the designated partial circle is displayed clockwise or counterclockwise. The second partial circle corresponding to the menu item assigned to the missing partial circle is not displayed. Therefore, according to the second aspect, each of the second partial circles corresponding to the clockwise or counterclockwise direction is displayed based on the selected first partial circle, so that the user (driver) ) Makes it easy to recognize which menu item in the designated first partial circle corresponds to each menu item assigned to the second partial circle displayed on the outer periphery.
　また、指定された部分円の外周に表示される第２の部分円と、車両の前方の前景とが重なる表示領域を最小限に抑えることができるため、非表示の表示領域に対応する部分の前方視野を確保でき、その結果、安全運転に寄与することができる。これは、特に、バックライト光源により透過表示を行う液晶表示装置（ＬＣＤ）等によりメニュー項目を示す表示像を生成し、虚像としてウインドシールド（フロントガラス）に照射し、この虚像を車両の前方の実景と重ねてユーザ（車両の運転者等）に視認させるヘッドアップディスプレイを表示装置として用いた場合に有効である。 In addition, since the display area where the second partial circle displayed on the outer periphery of the designated partial circle and the foreground in front of the vehicle overlap can be minimized, the portion corresponding to the non-display area is displayed. A front view can be secured, and as a result, it can contribute to safe driving. In particular, a display image showing menu items is generated by a liquid crystal display (LCD) or the like that performs transmissive display using a backlight light source, and is irradiated onto a windshield (front glass) as a virtual image. This is effective when a head-up display that is visually recognized by a user (such as a driver of a vehicle) superimposed on a real scene is used as a display device.
　また、第１又は第２の態様に従属する第３の態様において、
　前記表示制御手段は、
　前記ユーザ操作に応じて、前記ユーザの指が、前記第１の部分円の中心から前記外周の方向に移動したか、前記第１の部分円の領域に所定時間以上留まっているか、前記第１の部分円の領域を所定時間以上継続して触れているか、のうちの少なくとも一つを検出した場合に、前記第２の部分円のそれぞれを、前記第１の部分円の外周に表示させる制御を行う。 In the third aspect subordinate to the first or second aspect,
The display control means includes
In response to the user operation, whether the user's finger has moved in the direction of the outer periphery from the center of the first partial circle, or has remained in the region of the first partial circle for a predetermined time or more, Control for displaying each of the second partial circles on the outer circumference of the first partial circle when at least one of the partial circle regions is touched continuously for a predetermined time or more is detected. I do.
　第３の態様では、表示制御手段が、第２の部分円のそれぞれを、指定された第１の部分円の外周に表示させる制御を行うために、ユーザの指が第１の部分円の中心から外周の方向に移動したか、第１の部分円の領域に所定時間以上留まっているか、第１の部分円の領域を所定時間以上継続して触れているか、一つを検出したことを契機に行う。このため、第３の態様によれば、特に、ユーザの指が第１の部分円の中心から外周の方向に移動させる直観的な操作を行ったことを契機に、第２の部分円のそれぞれを指定された第１の部分円の外周に表示させる制御を行う場合に対応するメニュー項目を迅速に表示することができ、操作性や使い勝手がより向上する。 In the third aspect, the display control means controls the display of each of the second partial circles on the outer periphery of the designated first partial circle, so that the user's finger is at the center of the first partial circle. It has been detected that it has moved in the direction of the outer circumference, stayed in the area of the first partial circle for a predetermined time or more, or has continuously touched the area of the first partial circle for a predetermined time or more. To do. For this reason, according to the third aspect, in particular, each of the second partial circles is triggered by an intuitive operation in which the user's finger moves from the center of the first partial circle toward the outer periphery. The menu item corresponding to the case where control is performed to display on the outer periphery of the designated first partial circle can be quickly displayed, and the operability and usability are further improved.

The display control means includes
When the user operation including pressing of the operation surface is detected in a state where each of the second partial circles is displayed on the outer periphery of the designated first partial circle on the display device, The selection of the menu item assigned to each of the two partial circles is enabled, and when the user operation not including pressing of the operation surface is detected, the selection of the menu item assigned to each of the partial circles is enabled. Control to turn on.
　第４の態様によれば、表示制御手段が、操作面の押下操作、言い換えると、選択（決定）操作を検出しながら触れるかなぞる（指定操作）ユーザ操作により、指定された第１の部分円に対応する第２の部分円のそれぞれに割り当てたｎ＋１階層のメニュー項目の選択を有効にし、操作面の押下を含まないユーザ操作を検出した場合、言い換えると、選択（決定）操作が検出されなければ、部分円のそれぞれに割り当てた、ｎ階層に属するメニュー項目を含むメニュー項目の選択を有効にする。このため、第４の態様によれば、指定された第１の部分円の外周に第２の部分円のそれぞれが表示された状態でいずれのメニュー項目の選択（決定）も可能になるため、目的とするｎ＋１階層の操作メニューに至るまでに各階層のメニュー項目を表示して選択（決定）するという、従来の冗長な操作が省け、直接的（かつ直観的）に、目的とするメニュー項目を表示させてそのメニュー項目を選択できることから迅速で効率的なメニュー項目の選択が可能になる。 According to the fourth aspect, the first partial circle designated by the display control means by the user operation of tracing the touch while detecting the pressing operation of the operation surface, in other words, the selection (decision) operation (designation operation). When the user selects an n + 1 layer menu item assigned to each of the second partial circles corresponding to, and detects a user operation that does not include pressing the operation surface, in other words, a selection (determination) operation must be detected. For example, the selection of menu items including menu items belonging to the n hierarchy assigned to each of the partial circles is validated. For this reason, according to the fourth aspect, any menu item can be selected (determined) while each of the second partial circles is displayed on the outer periphery of the designated first partial circle. The target menu item can be directly (and intuitively) eliminated by eliminating the conventional redundant operation of displaying and selecting (determining) the menu items of each layer before reaching the target operation menu of the (n + 1) layer. Since the menu item can be selected by displaying the menu item, the menu item can be selected quickly and efficiently.

Or which of the menu items assigned to each of the partial circles is to be selected.
　第５の態様によれば、例えば、移動速度が所定の閾値と比較して遅いと判定された場合、第２の部分円のそれぞれに割り当てられているｎ＋１階層のメニュー項目を選択しようとしていると判定することで、指定された第１の部分円の外周に第２の部分円のそれぞれが表示された状態でいずれのメニュー項目の選択（決定）も可能になる。したがって、目的とするｎ＋１階層の操作メニューに至るまでに各階層のメニュー項目を表示して選択（決定）するという、従来の冗長な操作が省け、直接的（かつ直観的）に、目的とするメニュー項目を表示させてそのメニュー項目を選択できることから迅速で効率的なメニュー項目の選択が可能になる。 According to the fifth aspect, for example, when it is determined that the moving speed is slow compared to a predetermined threshold, the menu item of the (n + 1) th hierarchy assigned to each of the second partial circles is to be selected. By determining, any menu item can be selected (determined) in a state where each of the second partial circles is displayed on the outer periphery of the designated first partial circle. Therefore, the conventional redundant operation of displaying and selecting (determining) the menu items of each hierarchy before reaching the target n + 1 hierarchy operation menu is eliminated, and the objective is directly (and intuitively) intended. Since menu items can be displayed and selected, the menu items can be selected quickly and efficiently.

For this reason, for example, when there is an erroneous operation, each of the second partial circles corresponding to the adjacent first partial circle is automatically displayed on the outer periphery without restarting the operation from the beginning. Therefore, it is possible to know more quickly whether or not there is a target menu item, and it is possible to efficiently select (determine) the menu item.

　図４（ａ）に示すように、操作入力装置２００は、ステアリングホイール３に配設され、ユーザの指（ここでは、例えば親指とする）の位置（操作位置Ｃ）を検出する円環状の操作位置検出部２１０と、この操作位置検出部２１０と一体となって設けられ、操作位置検出部２１０が親指で押下されることで、ユーザによって選択（決定）がなされたことを検出する決定操作検出部２２０と、リターン処理を行うときに使用されるリターンスイッチ２３０と、を有する。 As shown in FIG. 4A, the operation input device 200 is disposed on the steering wheel 3, and is an annular operation for detecting the position (operation position C) of the user's finger (here, for example, the thumb). A position detection unit 210 and a determination operation detection that is provided integrally with the operation position detection unit 210 and detects that a selection (determination) has been made by the user by pressing the operation position detection unit 210 with a thumb. Section 220 and a return switch 230 used when performing return processing.
　操作位置検出部２１０は、円環状の操作面に、例えば、０時～２３時の方向に等間隔で配置された複数のセンサ電極（後述するセンサシート）が実装されており、この操作面をユーザが触れることにより、センサ電極毎の静電容量の変化を検出することで、ユーザの操作位置Ｃ（例えば、円環の０時の位置から２３時の位置）を検出することができる。又、ユーザが円環の操作面上を時計回りか反時計回りの方向に所定の軌跡を描くようになぞる操作を行うことによりその軌跡を位置情報として検出することもできる。なお、上述した例では、操作入力装置２００の操作を指（手）で行なうものとするが、ユーザの、その他の身体部位を用いてもよい。 The operation position detection unit 210 has a plurality of sensor electrodes (sensor sheets, which will be described later) arranged at equal intervals, for example, in the direction from 0:00 to 23:00 on an annular operation surface. By detecting a change in capacitance for each sensor electrode by touching the user, the user's operation position C (for example, the position of the ring from 0 o'clock to 23 o'clock) can be detected. Further, when the user performs an operation of tracing a predetermined locus in the clockwise or counterclockwise direction on the operation surface of the ring, the locus can be detected as position information. In the above example, the operation input device 200 is operated with a finger (hand), but other body parts of the user may be used.
　操作入力装置２００は、具体的に、ユーザの親指等が操作面に触れた位置（操作位置Ｃ）を検出するタッチセンサであり、例えば、図４（ｂ）に示すように、表面カバー２１１と、センサシート２１２と、スペーサ２１３と、を備える。操作入力装置２００は、ユーザが、親指等で操作面上を触れる操作、あるいは所定の軌跡を描くようになぞる操作を行った際に、ユーザの親指等が円環の操作面に触れている指定位置（操作位置Ｃ）を検出し、ユーザによる選択（決定）がなされると、その選択（決定）を検出して、例えば、選択（決定）がなされたことを示す信号（選択信号、言い換えれば選択（決定）検出信号）を出力する。 Specifically, the operation input device 200 is a touch sensor that detects a position where the user's thumb or the like touches the operation surface (operation position C). For example, as illustrated in FIG. The sensor sheet 212 and the spacer 213 are provided. The operation input device 200 specifies that the user's thumb or the like is touching the annular operation surface when the user performs an operation of touching the operation surface with a thumb or the like or a tracing operation so as to draw a predetermined locus. When the position (operation position C) is detected and selection (determination) is performed by the user, the selection (determination) is detected, for example, a signal (selection signal, in other words, indicating that the selection (determination) has been performed. Selection (determination) detection signal) is output.
　操作入力装置２００における表面カバー２１１は、合成樹脂等の遮光性の絶縁材料によってシート状に形成され、凸状断面の立体形状が、中心点Ｑを中心とする円の円周に沿って連続的に形成された凸部（凸領域）２１１ａ（図４（ｂ）において、放射状の模様が付された領域）と、凸部（凸領域）２１１ａに連接する比較的平坦な平坦部（平坦領域）２１１ｂと、を有する。凸部（凸領域）２１１ａは、山状の断面（凸状断面）を有し、その山（凸形状）は、中心点Ｑに向かう方向（内側）に長く、その反対方向である外側に短い輪郭線（稜線）を有する。その山（凸形状）が、中心点Ｑを中心とする円の円周に沿って、連続的に設けられることで凸部（凸領域）２１１ａが構成される。 The surface cover 211 in the operation input device 200 is formed in a sheet shape with a light-shielding insulating material such as synthetic resin, and the three-dimensional shape of the convex cross section is continuous along the circumference of a circle centered on the center point Q. Convex part (convex area) 211a (a region with a radial pattern in FIG. 4B) formed on the surface and a relatively flat flat part (flat area) connected to the convex part (convex area) 211a 211b. The convex portion (convex region) 211a has a mountain-shaped cross section (convex cross section), and the mountain (convex shape) is long in the direction toward the center point Q (inside) and short in the opposite direction. It has an outline (ridge line). The peaks (convex shape) are continuously provided along the circumference of a circle having the center point Q as the center, thereby forming a convex portion (convex region) 211a.
　また、図４（ｂ）に示されているように、表面カバー２１１における凸部（凸領域）２１１ａの下には、センサシート２１２が設けられており、これらを含む部分によって、上記の操作位置検出部２１０が構成される。ユーザは、例えば、上記の凸部（凸領域）２１１ａの、長手方向（中心点Ｑに向かう方向であり、言い換えれば内側方向）の斜面を指の触感で認識することにより、操作位置検出部２１０上における指のおおよその位置を認識することができ、操作入力装置２００を見なくても、操作入力装置２００を操作することができる。 Further, as shown in FIG. 4B, a sensor sheet 212 is provided under the convex portion (convex region) 211a of the surface cover 211, and the operation position described above is determined by the portion including these. A detection unit 210 is configured. For example, the user recognizes the slope of the convex portion (convex region) 211a in the longitudinal direction (the direction toward the center point Q, in other words, the inner direction) with the tactile sensation of the finger, thereby operating position detection unit 210. The approximate position of the finger on the top can be recognized, and the operation input device 200 can be operated without looking at the operation input device 200.
　言い換えれば、ブラインド操作が可能となる。なお、上記の凸部（凸領域）２１１ａが設けられない場合も想定され得るが、この場合でも、ユーザが、中心点Ｑを中心とした円の円周に沿って手（指）の位置を移動させた場合、ユーザは、自身が移動させた手（指）の軌跡（指等がタッチセンサの操作面に接触した位置の時間的変遷の跡）を知覚できることから、ユーザは、自身の手の位置が、円の円周上のおおよそどの位置にあるかの見当をつけることができる。したがって、この場合でも、ブラインド操作が可能である。 In other words, blind operation is possible. In addition, although the case where the above-mentioned convex part (convex area) 211a is not provided can be assumed, even in this case, the user places the position of the hand (finger) along the circumference of the circle centered on the center point Q. When moved, the user can perceive the trajectory of the hand (finger) that he / she has moved (the trace of the temporal transition of the position where the finger or the like has touched the operation surface of the touch sensor). You can get an idea of where the position of is located on the circumference of the circle. Therefore, even in this case, a blind operation is possible.
　センサシート２１２は、少なくとも凸部（凸領域）２１１ａに対応する表面カバー２１１の裏面側において、中心点Ｑを中心とする円の円周に沿って配設され、ユーザの指の操作位置Ｃを検出して、制御装置２０に、ユーザの指等の操作位置Ｃに関する情報（操作位置の情報、あるいは操作位置を示す信号）を出力する。センサシート２１２は、例えば、絞り加工により表面カバー２１１と一体成形されることで、表面カバー２１１と同様の形状に加工される（図４（ｂ）参照）。 The sensor sheet 212 is disposed along the circumference of a circle centered on the center point Q at least on the back surface side of the front cover 211 corresponding to the convex portion (convex region) 211a, and indicates the operation position C of the user's finger. It detects and outputs information (operation position information or a signal indicating the operation position) related to the operation position C of the user's finger or the like to the control device 20. The sensor sheet 212 is formed into the same shape as the surface cover 211 by being integrally formed with the surface cover 211 by drawing, for example (see FIG. 4B).
　このように一体成形されることで、表面カバー２１１とセンサシート２１２は、一枚のシートのようになり、上記の凸部（凸領域）２１１ａの段差形状は、その一枚のシートの曲がった部分（盛り上がった部分）で構成されることになる。また、このように一体成形されることで、表面カバー２１１の裏面とセンサシート２１２の表面とが当接する。これにより、表面カバー２１１の段差形状に対応して、センサシート２１２の検出部が配置されることになる。このように表面カバー２１１の段差形状に対応してセンサシート２１２の検出部が配置されているため、ユーザの指等の移動が、凸部（凸領域）２１１ａ等の段差形状を有した操作面上で行われるものであっても、例えば、制御装置２０が、ユーザの指の位置を検出することが可能である。 By being integrally molded in this way, the surface cover 211 and the sensor sheet 212 become like a single sheet, and the step shape of the convex portion (convex area) 211a is bent by the single sheet. It is composed of parts (raised parts). In addition, the back surface of the front cover 211 and the surface of the sensor sheet 212 come into contact with each other by being integrally molded in this way. Thereby, the detection part of the sensor sheet 212 is arrange | positioned corresponding to the level | step difference shape of the surface cover 211. FIG. Thus, since the detection part of the sensor sheet 212 is arrange | positioned corresponding to the level | step difference shape of the surface cover 211, the movement of a user's finger | toe etc. has a step shape, such as a convex part (convex area | region) 211a. Even if it is performed above, for example, the control device 20 can detect the position of the user's finger.
　スペーサ２１３は、センサシート２１２の裏面側に位置し、一体成形された表面カバー２１１とセンサシート２１２の形状に合わせて形成され、ユーザの指等によって、表面カバー２１１が表側から押圧された際に、上述した形状を保持する部材である。 The spacer 213 is located on the back side of the sensor sheet 212 and is formed in accordance with the shape of the integrally formed front cover 211 and sensor sheet 212. When the front cover 211 is pressed from the front side by a user's finger or the like. A member that holds the shape described above.
　決定操作検出部２２０は、操作位置検出部２１０の裏面側に複数（図４（ｂ）の例では３個）設けられる。決定操作検出部２２０は、制御装置２０と電気的に接続されており、ユーザが、操作位置検出部２１０の操作面（表面カバー２１１の凸部（凸領域））２１１ａを押下する操作（以下、押下操作という）を行うと、決定操作検出部２２０が押下され、これによって、ユーザによって選択（決定）がなされたことが検出され、選択（決定）がなされたことを示す信号（選択信号、言い換えれば選択（決定）検出信号）が出力される。出力された選択（決定）検出信号は、制御装置２０に送られる。制御装置２０は、送られてきた選択（決定）検出信号に基づき、例えば、ラジアル操作メニュー５００（Ｖ）に含まれる複数のメニュー項目Ｊのうちのどのメニュー項目が選択されたかを判定し、その選択に応じたメニュー項目Ｊを示す画像を生成して表示装置１０に表示する。これによって、選択された項目の内容に応じて、操作メニューの表示が切り替えられる。 A plurality (three in the example of FIG. 4B) of determination operation detection units 220 are provided on the back side of the operation position detection unit 210. The determination operation detection unit 220 is electrically connected to the control device 20, and the user presses the operation surface of the operation position detection unit 210 (the convex portion (convex region) of the surface cover 211) 211 a (hereinafter, referred to as “determination operation detection unit 220”). When the pressing operation is performed), the determination operation detection unit 220 is pressed, thereby detecting that selection (determination) has been performed by the user, and a signal indicating that selection (determination) has been performed (selection signal, in other words, (Selection (determination) detection signal) is output. The output selection (determination) detection signal is sent to the control device 20. Based on the selection (decision) detection signal sent, the control device 20 determines, for example, which menu item of a plurality of menu items J included in the radial operation menu 500 (V) is selected, and An image indicating the menu item J corresponding to the selection is generated and displayed on the display device 10. Thereby, the display of the operation menu is switched according to the content of the selected item.
　リターンスイッチ２３０は、操作位置検出部２１０及び決定操作検出部２２０とは離れた位置にあるスイッチである。ユーザが、リターンスイッチ２３０の操作面を押下する（言い換えれば、押下操作がなされる）と、制御装置２０にリターン信号が送信される。制御装置２０は、リターンスイッチ２３０からのリターン信号に基づき、ラジアル操作メニュー５００（Ｖ）の表示を、直近の過去のメニュー項目Ｊを示す画像に戻す。言い換えれば、直前の表示への切り替えが行われる。 The return switch 230 is a switch at a position away from the operation position detection unit 210 and the determination operation detection unit 220. When the user depresses the operation surface of the return switch 230 (in other words, a depressing operation is performed), a return signal is transmitted to the control device 20. Based on the return signal from the return switch 230, the control device 20 returns the display of the radial operation menu 500 (V) to an image showing the most recent past menu item J. In other words, switching to the previous display is performed.
　次に、図５を参照して本実施形態の車両用メニュー表示制御装置３００（特に、図１の制御装置２０）の、より具体的な構成について説明する。ここで、車両用メニュー表示制御装置３００とは、制御装置２０を制御中枢とし、表示装置１０と、操作入力装置２００とを含む構成をいう。なお、図５において、図１と共通する部分については同じ符号が示されている。 Next, a more specific configuration of the vehicle menu display control device 300 (particularly, the control device 20 of FIG. 1) of the present embodiment will be described with reference to FIG. Here, the vehicle menu display control device 300 refers to a configuration including the display device 10 and the operation input device 200 with the control device 20 as a control center. Note that, in FIG. 5, the same reference numerals are given to portions common to FIG. 1.
　制御装置２０は、ハードウエア的には、マイコン等のＣＰＵと、メモリを含む周辺ＬＳＩと、により構成され、機能的には、図５に示すように、操作情報取得部２０１と、画像生成部２０２（画像生成手段）と、表示制御部２０３（表示制御手段）と、処理実行部２０４（処理実行手段）と、記憶部２０５と、を含んで構成される。 The control device 20 is configured by a CPU such as a microcomputer and a peripheral LSI including a memory in terms of hardware, and functionally, as illustrated in FIG. 5, an operation information acquisition unit 201, an image generation unit, and the like. 202 (image generation means), a display control section 203 (display control means), a process execution section 204 (process execution means), and a storage section 205.
　操作情報取得部２０１は、ラジアル操作メニュー５００（Ｖ）に含まれる一つのメニュー項目を指定するために、操作入力装置２００を使用し、表示装置１０に表示された、円の任意の点を触れるかなぞるユーザの操作に応じて生成される位置情報、あるいは押下するユーザ操作に応じて生成される選択（決定）信号（選択決定情報）を、信号Ｉ／Ｆ４０経由で取得して、画像生成部２０２、表示制御部２０３、処理実行部２０４のそれぞれへ出力する。 The operation information acquisition unit 201 uses the operation input device 200 to touch one point of a circle displayed on the display device 10 in order to designate one menu item included in the radial operation menu 500 (V). Position information generated according to the user's operation to be traced or a selection (decision) signal (selection determination information) generated according to the user operation to be pressed is acquired via the signal I / F 40, and an image generation unit 202, the display control unit 203, and the process execution unit 204.
　画像生成部２０２は、円の中心を基点に半径方向に延びる２本の線と、２本の線の間の円弧で囲まれた部分円（セクタ領域）のそれぞれにメニュー項目を割り当てた、ラジアル操作メニューの画像を生成する画像生成手段として機能する。画像生成部２０２は、例えば、記憶部２０５に予め記憶されているメニューファイル等の中から使用可能なメニュー項目を読み出し、複数のメニュー項目の配置を割り当て、又、必要な情報を組み込むことで、複数のメニュー項目からなるラジアル操作メニュー５００（Ｖ）を生成し、記憶部２０５に割り当てられる作業領域に書き込む。なお、必要な情報の中には、後述するように配置されたメニュー項目が階層構造を有するか否かを示すフラグ情報も含まれる。 The image generation unit 202 assigns menu items to each of two lines extending radially from the center of the circle and a partial circle (sector area) surrounded by an arc between the two lines. It functions as an image generating means for generating an operation menu image. For example, the image generation unit 202 reads usable menu items from a menu file or the like stored in advance in the storage unit 205, assigns a plurality of menu items, and incorporates necessary information. A radial operation menu 500 (V) including a plurality of menu items is generated and written in a work area allocated to the storage unit 205. The necessary information includes flag information indicating whether or not menu items arranged as described later have a hierarchical structure.
　画像生成部２０２は、操作入力装置２００を使用し、部分円のそれぞれに割り当てたメニュー項目の一つを指定する、操作面を触れるかなぞるユーザ操作に応じて、ｎ階層（ｎは２以上の任意の整数）に属するメニュー項目を割り当てた第１の部分円が指定されると、指定されたメニュー項目の一つに対応するｎ＋１階層に属する１以上のメニュー項目を割り当てた第２の部分円をそれぞれ生成し、生成された第２の部分円のそれぞれを、指定された第１の部分円の外周に配置して更新されたラジアル操作メニューの画像を生成する画像生成手段、としても機能する。画像生成部２０２は、更新されたラジアル操作メニューの画像を記憶部２０５の作業領域に書き込む。 The image generation unit 202 uses the operation input device 200 and designates one of the menu items assigned to each of the partial circles. In response to a user operation of touching the operation surface, n layers (n is 2 or more) When a first partial circle to which a menu item belonging to (any integer) is assigned is specified, a second partial circle to which one or more menu items belonging to the n + 1 hierarchy corresponding to one of the specified menu items is assigned Each of the generated second partial circles is arranged on the outer periphery of the designated first partial circle, and also functions as image generation means for generating an image of the updated radial operation menu. . The image generation unit 202 writes the updated radial operation menu image in the work area of the storage unit 205.
　ここで、「部分円」とは、図７～図１０にラジアル操作メニュー５００（Ｖ）の一例として示すように、メニュー項目Ａ～Ｈのそれぞれが割り当てられた部分円である、セクタ領域５１１～５１８をいい、「指定された第１の部分円」とは、部分円のうち、例えば、空調ＥＣＵ４０４に関する空調装置のアイコンであるメニュー項目Ｂが配置されたセクタ領域５１２のことをいう。又、「第２の部分円」とは、指定された第１の部分円（セクタ領域５１２）の外周の領域に配置された、例えば、空調ＥＣＵ４０４に関する空調装置の風向きに関する処理メニュー項目のそれぞれが割り当てられた、セクタ領域５２１，５２２，５２３，５２４，５２５のことをいう。以下の説明では、便宜上、セクタ領域５２１，５２２，５２３，５２４，５２５を総称して階層展開領域５２０という。 Here, the “partial circle” is a partial circle to which each of the menu items A to H is assigned as shown in FIG. 7 to FIG. 10 as an example of the radial operation menu 500 (V). 518 and the “designated first partial circle” refers to, for example, the sector area 512 in which the menu item B, which is an icon of an air conditioner related to the air conditioning ECU 404, is arranged. In addition, the “second partial circle” refers to, for example, each of the processing menu items related to the wind direction of the air conditioner related to the air conditioner ECU 404 arranged in the outer peripheral area of the designated first partial circle (sector area 512). This refers to the allocated sector areas 521, 522, 523, 524, 525. In the following description, for convenience, the sector areas 521, 522, 523, 524, and 525 are collectively referred to as a hierarchy development area 520.
　また、「外周」とは、例えば、図７にラジアル操作メニュー５００（Ｖ）の一例として示すように、円５１０の半径ｒ１よりも大きな半径ｒ１１を有する同心円Ｃ内にあって、円５１０が配置され、表示される第１の表示領域を除き、円５１０の中心Ｐから半径方向に延びる２本の線ｒ１１，ｒ２１と、この２本の線の間の円弧ｃで囲まれた同心円Ｃの一部領域（階層展開領域５２０）が配置され、表示される第２の表示領域をいう。 Further, the “outer periphery” is, for example, in the concentric circle C having a radius r11 larger than the radius r1 of the circle 510 as shown in FIG. 7 as an example of the radial operation menu 500 (V), and the circle 510 is arranged. One of the concentric circles C surrounded by two lines r11 and r21 extending in the radial direction from the center P of the circle 510 and an arc c between the two lines, except for the first display area to be displayed. This is a second display area in which a partial area (hierarchical development area 520) is arranged and displayed.
　表示制御部２０３は、画像生成部２０２により生成された第２の部分円（階層展開領域５２０）のそれぞれを、指定された第１の部分円の外周に表示させる制御を行う表示制御手段として機能する。表示制御部２０３は、記憶部２０５の作業領域に書き込まれた、更新されたラジアル操作メニュー５００（Ｖ）の画像を、別の記憶領域に割り当てられた画像ＲＡＭ（あるいは外付けされた記憶装置）へ画像転送し、更新されたラジアル操作メニュー５００（Ｖ）の画像を、表示装置１０（表示器１２１）の表示タイミングに同期して画像ＲＡＭから読み込んで表示装置１０に表示する。 The display control unit 203 functions as a display control unit that performs control to display each of the second partial circles (hierarchy development area 520) generated by the image generation unit 202 on the outer periphery of the designated first partial circle. To do. The display control unit 203 uses the updated radial operation menu 500 (V) image written in the work area of the storage unit 205 as an image RAM (or an external storage device) assigned to another storage area. The image of the updated radial operation menu 500 (V) is read from the image RAM in synchronization with the display timing of the display device 10 (display device 121) and displayed on the display device 10.
　表示制御部２０３は、画像生成部２０２により生成された、更新されたラジアル操作メニュー５００（Ｖ）の第２の部分円（階層展開領域５２０）のそれぞれを、指定された第１の部分円（セクタ領域５１２）の表示位置を基準に、時計回りか反時計回りの方向の第１の部分円の外周に表示する制御を行なってもよい。ここで、回転方向は、操作情報取得部２０１によって逐次取得される、操作入力装置２００の操作位置検出部２１０から時系列に出力される位置情報に基づき判定される。 The display control unit 203 converts the second partial circle (hierarchical development area 520) of the updated radial operation menu 500 (V) generated by the image generation unit 202 to the designated first partial circle ( Control may be performed to display on the outer circumference of the first partial circle in the clockwise or counterclockwise direction with reference to the display position of the sector area 512). Here, the rotation direction is determined based on the position information output in time series from the operation position detection unit 210 of the operation input device 200, which is sequentially acquired by the operation information acquisition unit 201.
　表示制御部２０３は、ユーザ操作に応じて、ユーザの指が、第１の部分円（セクタ領域６１２）の中心から外周の方向に移動したか、第１の部分円（セクタ領域５１２）の領域に所定時間以上留まっているか、第１の部分円（セクタ領域５１２）を所定時間以上継続して触れているか、のうちの少なくとも一つを検出した場合に、第２の部分円（階層展開領域５２０）のそれぞれを、第１の部分円（セクタ領域５１２）の外周に表示させる制御を行なってもよい。 In response to a user operation, the display control unit 203 moves the user's finger from the center of the first partial circle (sector region 612) toward the outer periphery or the region of the first partial circle (sector region 512). Or when the first partial circle (sector area 512) is continuously touched for a predetermined time or more, the second partial circle (hierarchical development area) is detected. 520) may be displayed on the outer circumference of the first partial circle (sector area 512).
　例えば、スワイプ（スライド）操作によるユーザの指の移動の方向（円の外周に向かうか、円の中心に向かうか）については、表示制御部２０３が、操作入力装置２００（操作位置検出部２１０）から操作情報取得部２０１を介して時系列に取得される位置情報を逐次比較することにより判定が可能である。また、ユーザの指が第１の部分円の領域に所定時間以上留まっているか、あるいは第１の部分円の領域に所定時間以上継続して触れているかについては、操作入力装置２００から時系列に取得される位置情報と、図示省略した内蔵タイマによる時間監視とにより判定することができる。 For example, regarding the direction of movement of the user's finger by the swipe (slide) operation (going to the outer periphery of the circle or the center of the circle), the display control unit 203 uses the operation input device 200 (operation position detection unit 210). Can be determined by sequentially comparing the position information acquired in time series via the operation information acquisition unit 201. Whether the user's finger stays in the first partial circle region for a predetermined time or more or whether the user's finger continues to touch the first partial circle region for a predetermined time or more is determined in time series from the operation input device 200. This can be determined by the acquired position information and time monitoring by a built-in timer (not shown).
　表示制御部２０３は、表示装置１０に、指定された第１の部分円（セクタ領域５１２）の外周に第２の部分円（階層展開領域５２０）のそれぞれが表示された状態で、操作入力装置２００の円環状の操作面の押下を含むユーザ操作（例えば、親指で決定操作検出部２２０を押しながら人差し指でセクタ領域５２１～５２５のいずれかに触れる）が検出された場合に、第２の部分円（階層展開領域５２０）のそれぞれに割り当てたｎ＋１階層のメニュー項目の選択を有効にし、操作面の押下を含まないユーザ操作を検出すると、部分円（セクタ領域５１１～５１８）のそれぞれに割り当てたメニュー項目Ａ～Ｈの選択を有効にする制御を行なってもよい。言い換えると、更新されたラジアル操作メニュー５００（Ｖ）が表示された状態で、更新前後のいずれのメニュー項目の選択（決定）も可能になる。 The display control unit 203 operates the operation input device in a state where each of the second partial circles (hierarchy development region 520) is displayed on the outer periphery of the designated first partial circle (sector region 512) on the display device 10. The second part is detected when a user operation including pressing of an annular operation surface of 200 (for example, touching any of the sector regions 521 to 525 with the index finger while pressing the determination operation detection unit 220 with the thumb) is detected. When the selection of the menu item of the (n + 1) -th layer assigned to each of the circles (hierarchy development area 520) is enabled and a user operation that does not include pressing of the operation surface is detected, it is assigned to each of the partial circles (sector areas 511 to 518) Control for enabling selection of menu items A to H may be performed. In other words, any menu item before and after the update can be selected (determined) while the updated radial operation menu 500 (V) is displayed.
　画像生成部２０２は、指定された第１の部分円（セクタ領域５１２）の中心Ｐを基点に半径方向に延びる２本の線ｒ１，ｒ２がなす角度β（図７）を、第２の部分円（セクタ領域５２１）の中心Ｐを基点に半径方向に延びる２本の線ｒ１１，ｒ１２がなす角度α（図７）より大きく設定して更新されたラジアル操作メニューの画像を生成してもよく、このとき、表示制御部２０３は、操作情報取得部２０１からユーザ操作に基づき逐次取得される位置情報に基づきユーザの指の移動速度を演算により求め、その移動速度に応じて、第２の部分円（階層展開領域５２０）のそれぞれに割り当てられているｎ＋１階層のメニュー項目か、部分円（セクタ領域５１１～５１８）のそれぞれに割り当てられているメニュー項目Ａ～Ｈのいずれを選択しようとしているのかを判定する。 The image generation unit 202 sets the angle β (FIG. 7) formed by the two lines r1 and r2 extending in the radial direction from the center P of the designated first partial circle (sector region 512) as the second part. An image of the updated radial operation menu may be generated by setting it larger than the angle α (FIG. 7) formed by the two lines r11 and r12 extending in the radial direction from the center P of the circle (sector region 521). At this time, the display control unit 203 obtains the movement speed of the user's finger based on the position information sequentially acquired from the operation information acquisition section 201 based on the user operation, and calculates the second part according to the movement speed. Select either n + 1 layer menu item assigned to each circle (hierarchical development area 520) or menu item AH assigned to each partial circle (sector area 511 to 518). Determine if you are going.
　例えば、移動速度を所定の閾値と比較して遅いと判定された場合、第２の部分円（階層展開領域５２０）のそれぞれに割り当てられているｎ＋１階層のメニュー項目を選択しようとしていると判定する。表示制御部２０３は、例えば、時系列に取得される位置情報から一定時間毎の移動距離を算出し、その一定時間で除算することにより、指の移動速度を算出することができる。 For example, if it is determined that the moving speed is slow compared to a predetermined threshold, it is determined that an attempt is made to select an n + 1 layer menu item assigned to each of the second partial circles (layer development region 520). . For example, the display control unit 203 can calculate the moving speed of the finger by calculating the moving distance for every fixed time from the position information acquired in time series and dividing by the fixed time.
　画像生成部２０２は、ラジアル操作メニュー５００（Ｖ）における円の中心Ｐを通って半径方向に延びる基準線分（停止位置）と、円の中心Ｐと指定位置とを結ぶ線分とでなす角度（中心角）を演算することにより、角度範囲αの配置領域を求めることができる。βについても同様である。このため、表示制御部２０３は、更新前後のラジアル操作メニュー５００（Ｖ）を表示するにあたり、操作入力装置２００から出力される位置情報と、表示装置１０の表示位置との間で同期をとるために、操作入力装置２００における操作位置検出部２１０の円環状の操作面の中心Ｑを基点としたユーザによる回転操作の相対角度と、表示装置１０に表示されたラジアル操作メニュー５００（Ｖ）の円の中心Ｐを基点とする指定位置との相対角度とを略一致させるための制御を行う必要がある。 The image generation unit 202 forms an angle formed by a reference line segment (stop position) extending in the radial direction through the center P of the circle in the radial operation menu 500 (V) and a line segment connecting the center P of the circle and the specified position. By calculating (center angle), an arrangement region of the angle range α can be obtained. The same applies to β. For this reason, the display control unit 203 synchronizes the position information output from the operation input device 200 and the display position of the display device 10 when displaying the radial operation menu 500 (V) before and after the update. Furthermore, the relative angle of the rotation operation by the user based on the center Q of the annular operation surface of the operation position detection unit 210 in the operation input device 200 and the circle of the radial operation menu 500 (V) displayed on the display device 10. It is necessary to perform control for making the relative angle with the designated position with the center P of the base point substantially coincide.
　画像生成部２０２は、指定された第１の部分円（セクタ領域５１２）の中心Ｐを基点に半径方向に延びる２本の線がなす角度（例えば、図８のβ）と、第２の部分円（階層展開領域５２０）のそれぞれの中心Ｐを基点に半径方向に延びる２本の線がなす角度の合計（例えば、図８のα１＋α２＋α３＋αα４＋α５）とが等しくなるように設定して更新されたラジアル操作メニュー５００（Ｖ）の画像を生成してもよい。このとき、表示制御部２０３は、第２の部分円（階層展開領域５２０）のそれぞれを、指定された第１の部分円（セクタ領域５１２）の外周に並べて表示する制御を行なう。 The image generation unit 202 calculates the angle (for example, β in FIG. 8) formed by two lines extending in the radial direction from the center P of the designated first partial circle (sector area 512), and the second part. Radial operation updated by setting the sum of angles formed by two lines extending radially from the center P of each circle (hierarchical development area 520) (for example, α1 + α2 + α3 + αα4 + α5 in FIG. 8) to be equal. An image of the menu 500 (V) may be generated. At this time, the display control unit 203 performs control to display the second partial circles (hierarchical development area 520) side by side on the outer periphery of the designated first partial circle (sector area 512).
　表示制御部２０３は、ｎ＋１階層に属する１以上のメニュー項目の一つを指定するときに、操作入力装置２００の円環状の操作面を触れるかなぞるユーザ操作に応じて逐次取得される位置情報に基づき、ユーザの指の位置が、第２の部分円（階層展開領域５２０）の位置を外れたことが検出された場合、指定された第１の部分円（セクタ領域５１２）の時計回りか半時計回りの方向に隣接する第１の部分円（セクタ領域５１１又は５１３）に対応する、ｎ＋１階層に属する１以上のメニュー項目から成る第２の部分円のそれぞれを、隣接する第１の部分円（セクタ領域５１１又は５１３）の外周に表示させる制御を行なってもよい。 When the display control unit 203 designates one of one or more menu items belonging to the n + 1 hierarchy, the position information is sequentially acquired according to a user operation that traces the annular operation surface of the operation input device 200. Based on this, when it is detected that the position of the user's finger is out of the position of the second partial circle (hierarchical development area 520), the designated first partial circle (sector area 512) is rotated clockwise or half-way. Each of the second partial circles made up of one or more menu items belonging to the n + 1 hierarchy corresponding to the first partial circle (sector area 511 or 513) adjacent in the clockwise direction is designated as the adjacent first partial circle. You may control to display on the outer periphery of (sector area | region 511 or 513).
　表示制御部２０３は、外部から取得される車両の車速情報に応じて、第２の部分円（階層展開領域５２０）のそれぞれの表示サイズを変更して第１の部分円（セクタ領域５１２）の外周に表示させる制御を行なってもよい。なお、車速情報は、入出力Ｉ／Ｆ３０を介して車載機器４００のうちのいずれからかＢＵＳ経由で取得するか、あるいは車両１の任意の場所に実装された加速度センサから出力される加速度情報を微分する等によって取得することができる。 The display control unit 203 changes the display size of each of the second partial circles (hierarchy development area 520) according to the vehicle speed information acquired from the outside to change the first partial circle (sector area 512). You may perform control displayed on an outer periphery. The vehicle speed information is acquired from any of the in-vehicle devices 400 via the input / output I / F 30 or via the BUS, or acceleration information output from an acceleration sensor mounted at an arbitrary location of the vehicle 1. It can be obtained by differentiating.
　処理実行部２０４は、最終的に選択されるメニュー項目に対応する車載機器４００の操作処理を実行する処理実行手段として機能する。例えば、図７に示すセクタ領域５２２（階層展開領域５２０）のメニュー項目を、ユーザが操作入力装置２００を使用して操作（押下）すると、決定操作検出部２２０が、ユーザによって選択（決定）がなされたことを検出し、選択（決定）がなされたことを示す信号が出力されることで、セクタ領域５２２に割り当てられたメニュー項目にしたがう車載機器４００の処理を実行させることができる。セクタ領域５２２に割り当てられたメニュー項目が押下された場合、その選択（決定）信号（選択決定情報）により、空調ＥＣＵ４０４が起動され、空調ＥＣＵ４０４は、所定の風量でユーザの上体と脚の両方に風向する制御を行う。 The process execution unit 204 functions as a process execution unit that executes an operation process of the in-vehicle device 400 corresponding to the menu item finally selected. For example, when the user operates (presses) the menu item in the sector area 522 (hierarchical expansion area 520) shown in FIG. 7 using the operation input device 200, the determination operation detection unit 220 selects (decides) by the user. By detecting that it has been done and outputting a signal indicating that selection (determination) has been made, the processing of the in-vehicle device 400 according to the menu item assigned to the sector area 522 can be executed. When the menu item assigned to the sector area 522 is pressed, the air conditioning ECU 404 is activated by the selection (determination) signal (selection determination information), and the air conditioning ECU 404 uses both the upper body and legs of the user with a predetermined air volume. The wind direction is controlled.
　記憶部２０５には、スタティックＲＡＭやダイナミックＲＡＭ、あるいはフラッシュＲＡＭ等の半導体記憶素子が実装されている。この半導体記憶素子に、本実施形態のＧＵＩプログラム、画像データ、ラジアル操作メニュー生成時に使用される作業領域、そして、図１に、破線の四角で示される虚像表示可能領域１０１の写しである画像ＲＡＭ領域が割り当てられ、記憶されている。 The storage unit 205 is mounted with a semiconductor storage element such as static RAM, dynamic RAM, or flash RAM. In this semiconductor memory element, an image RAM which is a copy of the GUI program, the image data, the work area used when generating the radial operation menu of the present embodiment, and the virtual image displayable area 101 indicated by a broken-line square in FIG. Area is allocated and stored.
　なお、上述した操作情報取得部２０１、画像生成部２０２、表示制御部２０３、処理実行部２０４のそれぞれは、いずれも制御装置２０が内蔵するマイコン等のＣＰＵが、記憶部２０５のプログラム領域に格納されたＧＵＩプログラムを逐次読み出し実行することにより、それぞれが有する機能を実現するものとする。 Note that each of the operation information acquisition unit 201, the image generation unit 202, the display control unit 203, and the processing execution unit 204 described above is stored in the program area of the storage unit 205 by a CPU such as a microcomputer built in the control device 20. It is assumed that the functions possessed by each are realized by sequentially reading out and executing the GUI programs.
（実施形態の動作）
　以下、本実施形態の車載機器操作システム１００による車載機器操作処理について、図６、図７を参照しながら詳細に説明する。図６は、本実施形態の車載機器操作システム１００なおける車載機器操作処理の手順を説明するフローチャートであり、又、図７は、そのフローチャートに示す処理を補足する意味で示した図であり、表示装置１０に表示される更新前後のラジアル操作メニュー５００（Ｖ）の一例の他に、操作入力装置２００による操作位置との対応関係も示している。 (Operation of the embodiment)
Hereinafter, the in-vehicle device operation processing by the in-vehicle device operation system 100 of the present embodiment will be described in detail with reference to FIGS. 6 and 7. FIG. 6 is a flowchart for explaining the procedure of the in-vehicle device operation process in the in-vehicle device operation system 100 of the present embodiment, and FIG. 7 is a diagram shown in the sense of supplementing the process shown in the flowchart. In addition to an example of the radial operation menu 500 (V) before and after update displayed on the display device 10, the correspondence relationship with the operation position by the operation input device 200 is also shown.
　本実施形態の車載機器操作システム１００は、車両１の起動（車載機器操作システムＯＮ）に基づいて動作を開始し、車両１が停止（車載機器操作システムＯＦＦ）する際に動作を終了する。制御装置２０は、車両１の起動（車載機器操作システムＯＮ）に伴い、画像データを記憶部２０５から読み出してラジアル操作メニュー５００（Ｖ）を生成し、表示装置１０に対して、生成されたラジアル操作メニュー５００（Ｖ）の画像信号を出力し、図７の上部に、円５１０で示す第１の表示領域に表示する（ステップＳ１０１）。車両１の起動後に表示されるラジアル操作メニュー５００（Ｖ）の各メニュー項目は、それ以前の車両１が停止する際に表示装置１０に表示されていたメニュー項目と同じものである。 The in-vehicle device operation system 100 of the present embodiment starts the operation based on the start of the vehicle 1 (the in-vehicle device operation system ON), and ends the operation when the vehicle 1 stops (the in-vehicle device operation system OFF). The control device 20 reads the image data from the storage unit 205 and generates a radial operation menu 500 (V) when the vehicle 1 is activated (on-vehicle device operation system ON), and generates the generated radial to the display device 10. The image signal of the operation menu 500 (V) is output and displayed in the first display area indicated by a circle 510 at the top of FIG. 7 (step S101). Each menu item of the radial operation menu 500 (V) displayed after the vehicle 1 is started is the same as the menu item displayed on the display device 10 when the previous vehicle 1 stops.
　制御装置２０は、画像生成部２０２が、円５１０の中心Ｐを基点に半径方向に延びる２本の線ｒ１，ｒ２と、この２本の線ｒ１，ｒ２の間の円弧で囲まれた部分円（セクタ領域５１１～５１８）のそれぞれにメニュー項目Ａ～Ｈ（セクタ領域５１１～５１８）を割り当てたラジアル操作メニュー５００（Ｖ）の画像を生成し、表示制御部２０３が、そのラジアル操作メニュー５００（Ｖ）を、円５１０の領域で示す第１の表示領域に表示する。画像生成部２０２は、記憶部２０５の一部領域に予め記憶されているメニューファイルの中から使用可能なメニュー項目Ａ～Ｈを読み出し、このメニュー項目Ａ～Ｈを、それぞれのセクタ領域５１１～５１８に配置（合成）し、又、必要な情報を組み込むことで、複数のメニュー項目Ａ～Ｈからなるラジアル操作メニュー５００（Ｖ）を生成し、記憶部２０５の一部記憶領域に更に割り当てた作業領域に書き込む。ここで必要な情報の中には、配置されたメニュー項目が階層構造を有するか否かを示すフラグ情報も含まれる。 In the control device 20, the image generation unit 202 includes two lines r1 and r2 that extend in the radial direction from the center P of the circle 510, and a partial circle surrounded by an arc between the two lines r1 and r2. An image of the radial operation menu 500 (V) in which the menu items A to H (sector areas 511 to 518) are assigned to the respective (sector areas 511 to 518) is generated, and the display control unit 203 displays the radial operation menu 500 (V). V) is displayed in the first display area indicated by the area of the circle 510. The image generation unit 202 reads usable menu items A to H from menu files stored in advance in a partial area of the storage unit 205, and stores the menu items A to H in the sector areas 511 to 518, respectively. Is created (by combining) and incorporating necessary information to generate a radial operation menu 500 (V) comprising a plurality of menu items A to H, and further assigned to a partial storage area of the storage unit 205 Write to the area. The necessary information includes flag information indicating whether or not the arranged menu item has a hierarchical structure.
　次に、表示制御部２０３は、操作入力装置２００から操作情報取得部２０１を介してユーザの指の位置情報を取得し（ステップＳ１０２）、画像生成部２０２に引き渡す。ここで、ユーザが、操作入力装置２００の円環状の操作面上で操作位置をなぞるスワイプ（スライド）操作を行った場合、表示制御部２０３は、その操作位置の移動に基づく指定位置と、スワイプの方向とを判定する（ステップＳ１０３）。ここで判定されるスワイプの方向とは、例えば、図７の中央左に、操作入力装置２００の操作の軌跡（矢印ｘ）で示すように、ラジアル操作メニュー５００（Ｖ）の中心Ｐから外周方向に向かうか、あるいは、矢印ｙで示すように、ラジアル操作メニュー５００（Ｖ）の外周方向から中心Ｐに向かうかのいずれかをいう。ステップＳ１０３では、前者（矢印ｘの方向）を判定する。 Next, the display control unit 203 acquires the position information of the user's finger from the operation input device 200 via the operation information acquisition unit 201 (step S102), and delivers it to the image generation unit 202. Here, when the user performs a swipe (slide) operation that traces the operation position on the annular operation surface of the operation input device 200, the display control unit 203 performs the swipe operation with the designated position based on the movement of the operation position. Is determined (step S103). The direction of swipe determined here is, for example, from the center P of the radial operation menu 500 (V) to the outer peripheral direction as shown by the operation trajectory (arrow x) of the operation input device 200 at the center left in FIG. Or toward the center P from the outer peripheral direction of the radial operation menu 500 (V) as indicated by an arrow y. In step S103, the former (the direction of the arrow x) is determined.
　ここでは、ユーザ（運転者）が、例えば、表示装置１０上の、上位階層に属するメニュー項目Ｂを割り当てた部分円（セクタ領域５１２）に対応する操作入力装置２００上（図７の中央左に、点線で示すメニュー項目Ｂの位置）を触れながら、円環状の操作面の中心Ｑから外周方向になぞる矢印ｘで示す方向にスワイプ操作を行なった場合を想定する。このとき、表示制御部２０３は、操作情報取得部２０１を介して取得される位置情報の変化に基づき、そのスワイプ操作を検出すると（ステップＳ１０３“ＹＥＳ”）、画像生成部２０２が、指定されたｎ階層（上位階層）のメニュー項目Ｂ（セクタ領域５１２）に対応する、ｎ＋１階層（下位階層）に属する１以上のメニュー項目を割り当てた第２の部分円（セクタ領域５２１～５２５）をそれぞれ生成する。 Here, the user (driver), for example, on the operation input device 200 corresponding to the partial circle (sector area 512) to which the menu item B belonging to the upper hierarchy is assigned on the display device 10 (in the center left of FIG. 7). Suppose that a swipe operation is performed in the direction indicated by the arrow x tracing from the center Q of the annular operation surface to the outer peripheral direction while touching the position of the menu item B indicated by the dotted line. At this time, when the display control unit 203 detects the swipe operation based on the change in the position information acquired through the operation information acquisition unit 201 (step S103 “YES”), the image generation unit 202 is designated. Second partial circles (sector areas 521 to 525) each assigned one or more menu items belonging to the n + 1 hierarchy (lower hierarchy) corresponding to the menu item B (sector area 512) of the n hierarchy (upper hierarchy) are generated. To do.
　なお、指定されたメニュー項目が階層構造を有するメニュー項目であるか否かは、画像生成部２０２が、初期のラジアル操作メニュー５００（Ｖ）の画像生成時に、記憶部２０５の作業領域に書き込んだ必要情報のうちのフラグ情報を参照することにより判定することができる。 Whether or not the specified menu item is a menu item having a hierarchical structure is written in the work area of the storage unit 205 by the image generation unit 202 when the image of the initial radial operation menu 500 (V) is generated. The determination can be made by referring to the flag information of the necessary information.
　続いて、画像生成部２０２は、図７の下部に示すように、生成した第２の部分円（セクタ領域５２１～５２５）のそれぞれを、指定された第１の部分円（セクタ領域５１２）の外周（階層展開領域５２０）に配置することにより、更新されたラジアル操作メニューの画像を生成する。このとき、指定された第１の部分円（セクタ領域５１２）の中心Ｐを基点に半径方向に延びる２本の線ｒ１，ｒ２がなす角度βを、第２の部分円（セクタ領域５２１）の中心Ｐを基点に半径方向に延びる２本の線ｒ１１，ｒ１３がなす角度αより大きく設定して、更新されたラジアル操作メニュー５００（Ｖ）の画像を生成する。続いて、画像生成部２０２は、更新されたラジアル操作メニュー５００（Ｖ）の画像を記憶部２０５の作業領域に書き込む。 Subsequently, as shown in the lower part of FIG. 7, the image generation unit 202 converts each of the generated second partial circles (sector areas 521 to 525) into the designated first partial circle (sector area 512). An image of the updated radial operation menu is generated by arranging it on the outer periphery (hierarchical development area 520). At this time, the angle β formed by the two lines r1 and r2 extending in the radial direction from the center P of the designated first partial circle (sector region 512) is defined as the second partial circle (sector region 521). An image of the updated radial operation menu 500 (V) is generated by setting the angle P to be larger than the angle α formed by the two lines r11 and r13 extending in the radial direction from the center P as a base point. Subsequently, the image generation unit 202 writes the updated image of the radial operation menu 500 (V) in the work area of the storage unit 205.
　なお、画像生成部２０２は、ラジアル操作メニュー５００（Ｖ）における円５１０の中心Ｐを通って半径方向に延びる基準線分（操作入力装置２００上でのユーザの指の停止位置）と、円５１０の中心Ｐとユーザの指の指定位置とを結ぶ線分とでなす角度（中心角）とを演算することにより、角度範囲α，βの配置領域を求めることができる。このため、表示制御部２０３は、更新前後のラジアル操作メニュー５００（Ｖ）を表示するにあたり、操作入力装置２００から出力される位置情報と、表示装置１０の表示位置との間で同期をとるために、操作入力装置２００における操作位置検出部２１０の円環状の操作面の中心Ｑを基点としたユーザによる回転操作の相対角度と、表示装置１０に表示されたラジアル操作メニュー５００（Ｖ）の円５１０の中心Ｐを基点とする指定位置との相対角度とを略一致させるための制御を行う。 Note that the image generation unit 202 includes a reference line segment (a stop position of the user's finger on the operation input device 200) extending in the radial direction through the center P of the circle 510 in the radial operation menu 500 (V), and the circle 510. By calculating the angle (center angle) formed by the line segment connecting the center P of the user and the designated position of the user's finger, the arrangement area of the angle ranges α and β can be obtained. For this reason, the display control unit 203 synchronizes the position information output from the operation input device 200 and the display position of the display device 10 when displaying the radial operation menu 500 (V) before and after the update. Furthermore, the relative angle of the rotation operation by the user based on the center Q of the annular operation surface of the operation position detection unit 210 in the operation input device 200 and the circle of the radial operation menu 500 (V) displayed on the display device 10. Control is performed to substantially match the relative angle with the designated position with the center P of 510 as the base point.
　表示制御部２０３は、記憶部２０５の作業領域に書き込まれた、更新されたラジアル操作メニュー５００（Ｖ）を記憶部２０５の画像ＲＡＭ領域に転送し、更新されたラジアル操作メニュー５００（Ｖ）を画像ＲＡＭ領域から表示装置１０（表示器１２１）の表示タイミングに同期して読み出し、指定されたセクタ領域５１２の外周の第２の表示領域（階層展開領域５２０）に表示させる制御を行う（ステップ１０４）。 The display control unit 203 transfers the updated radial operation menu 500 (V) written in the work area of the storage unit 205 to the image RAM area of the storage unit 205, and the updated radial operation menu 500 (V). Control is performed to read from the image RAM area in synchronism with the display timing of the display device 10 (display 121) and to display the second display area (hierarchical development area 520) on the outer periphery of the designated sector area 512 (step 104). ).
　このとき、表示制御部２０３は、階層展開領域５２０に配置された第２の部分円（セクタ領域５２１～５２５）のそれぞれを、指定されたセクタ領域５１２の表示位置を基準に、時計回りか反時計回りの方向のセクタ領域５１２の外周に表示する。言い換えれば、指定されたセクタ領域５１２の外周には、指定された部分円（セクタ領域５１２）に割り当てたｎ階層のメニュー項目Ｂに対応するｎ＋１階層のメニュー項目を割り当てた第２の部分円（セクタ領域５２１～５２５）のみが表示される。このため、ユーザは、外周に表示された第２の部分円（セクタ領域５２１～５２５）に割り当てたｎ＋１階層のそれぞれのメニュー項目が、指定されたセクタ領域５１２のどのｎ階層のメニュー項目に対応しているかを認識することが容易になる。 At this time, the display control unit 203 turns each of the second partial circles (sector areas 521 to 525) arranged in the hierarchical development area 520 clockwise or counterclockwise with reference to the display position of the designated sector area 512. It is displayed on the outer periphery of the sector area 512 in the clockwise direction. In other words, on the outer periphery of the designated sector area 512, a second partial circle (n + 1 layer menu item corresponding to the n layer menu item B assigned to the designated partial circle (sector area 512)) ( Only the sector areas 521 to 525) are displayed. Therefore, the user corresponds to the menu item of any n layer in the designated sector region 512, with each menu item of the n + 1 layer assigned to the second partial circle (sector regions 521 to 525) displayed on the outer periphery. It becomes easy to recognize what is being done.
　次に、制御装置２０が、操作入力装置２００（決定操作検出部２２０）から選択（決定）信号を取り込むと、表示制御部２０３は、操作情報取得部２０１を介し、その選択（決定）情報とともに位置情報を取り込み、その位置情報に対応したメニュー項目の選択に応じた処理を実行する。表示装置１０に、指定された第１の部分円（セクタ領域５１２）の外周における階層展開領域５２０に配置された第２の部分円（セクタ領域５２１～５２５）のそれぞれに割り当てられたメニュー項目が表示された状態で、操作入力装置２００の円環状の操作面の押下を含むユーザ操作を検出すると、言い換えると、第２の表示領域に表示した第２の部分円（セクタ領域５２１～５２５）のいずれかがが選択（決定）されると（ステップＳ１０５“ＹＥＳ”）、表示制御部２０３は、更に、選択された第２の部分円（セクタ領域５２１～５２５のいずれか）のメニュー項目に関連付けられた下位の階層メニュー項目の有無を判定する（ステップＳ１０６）。 Next, when the control device 20 takes in a selection (determination) signal from the operation input device 200 (determination operation detection unit 220), the display control unit 203, along with the selection (determination) information, via the operation information acquisition unit 201. The position information is taken in, and processing corresponding to the selection of the menu item corresponding to the position information is executed. Menu items assigned to each of the second partial circles (sector areas 521 to 525) arranged in the hierarchical development area 520 on the outer periphery of the designated first partial circle (sector area 512) are displayed on the display device 10. When a user operation including pressing of the annular operation surface of the operation input device 200 is detected in the displayed state, in other words, the second partial circles (sector areas 521 to 525) displayed in the second display area are detected. When any one is selected (determined) (step S105 “YES”), the display control unit 203 further associates with the menu item of the selected second partial circle (any one of the sector areas 521 to 525). The presence / absence of the subordinate hierarchical menu item is determined (step S106).
　ここで、下位の階層メニュー項目が無い（選択されたメニュー項目が最下層のメニュー項目である）と判定された場合（ステップＳ２０６“ＹＥＳ”）、その選択が最終選択であるため、処理実行部２０４が、そのメニュー項目に対応する実行制御を行なうと共に、表示制御部２０３が、表示装置１０を初期メニューの表示に復帰させる（ステップＳ１０７）。なお、ステップ１０６で、更に、下位階層のメニュー項目があると判定されると（ステップＳ１０６“ＮＯ”）、ステップＳ１０２の処理に戻り、表示制御部２０３は、選択されたメニュー項目に関連付けられた次階層のメニュー項目を表示するための処理を実行する。 Here, if it is determined that there is no lower-level menu item (the selected menu item is the lowest-level menu item) (“YES” in step S206), the selection is the final selection, so the process execution unit 204 performs execution control corresponding to the menu item, and the display control unit 203 returns the display device 10 to the display of the initial menu (step S107). If it is determined in step 106 that there is a lower-level menu item (“NO” in step S106), the process returns to step S102, and the display control unit 203 is associated with the selected menu item. Executes the process for displaying the menu item of the next layer.
　一方、ステップＳ１０５で、階層展開領域５２０で示す第２の表示領域に表示したセクタ領域５２１～５２５が選択（決定）されていないと判定された場合（ステップＳ１０５“ＮＯ”）、すなわち、操作入力装置２００の円環状の操作面の押下を含まないユーザ操作を検出すると、表示制御部２０３は、例えば、図７の中央左にｙで示す、円５１０で示す第１の表示領域の外周方向から円５１０の中心Ｐへ向かう方向にスワイプ（シフト）操作が行われたか否かを判定する（ステップＳ１０８）。ここで、ラジアル操作メニュー５００（Ｖ）の外周方向から円５１０の中心Ｐへ向かってスワイプ操作が行われたと判定されると（ステップＳ１０８“ＹＥＳ”）、表示制御部２０３は、階層展開領域５２０で示す第２の表示領域に表示されたｎ＋１階層の各メニュー項目を割り当てたセクタ領域５２１～５２５（階層展開領域５２０）を非表示にするための制御を行う（ステップＳ１０９）。言い換えれば、図７の上部に示す、初期のラジアル操作メニュー５００（Ｖ）の表示に戻す。 On the other hand, if it is determined in step S105 that the sector areas 521 to 525 displayed in the second display area indicated by the hierarchy development area 520 are not selected (determined) (step S105 “NO”), that is, the operation input When detecting a user operation that does not include pressing the annular operation surface of the apparatus 200, the display control unit 203, for example, from the outer peripheral direction of the first display area indicated by a circle 510 indicated by y at the center left in FIG. It is determined whether or not a swipe (shift) operation has been performed in a direction toward the center P of the circle 510 (step S108). If it is determined that the swipe operation is performed from the outer circumferential direction of the radial operation menu 500 (V) toward the center P of the circle 510 (step S108 “YES”), the display control unit 203 displays the hierarchy development area 520. Control is performed to hide the sector areas 521 to 525 (hierarchy development area 520) to which the menu items of the (n + 1) th hierarchy displayed in the second display area indicated by (ii) are assigned (step S109). In other words, the display returns to the display of the initial radial operation menu 500 (V) shown in the upper part of FIG.
　次に、制御装置２０が、操作入力装置２００（決定操作検出部２２０）から選択（決定）信号を取り込むと、表示制御部２０３は、操作情報取得部２０１を介し、その選択（決定）情報とともに位置情報を取り込み、円５１０で示す第１の表示領域に表示したメニュー項目Ａ～Ｈ（セクタ領域５１１～５１８）が選択されたか否かを判定する（ステップＳ１１０）。ここで、第１の表示領域に表示したメニュー項目Ａ～Ｈ（セクタ領域５１１～５１８）のいずれかが選択されたことを検出すると、ステップＳ１０６の処理に戻り、表示制御部２０３が、選択されたメニュー項目Ａ～Ｈのいずれかに関連付けられたｎ＋１の下位階層のメニュー項目の有無を判定し（ステップＳ１０６）、下位階層のメニュー項目が無いと判定された場合（ステップＳ１０６“ＹＥＳ”）、その選択が最終選択であるため、処理実行部２０４が、そのメニュー項目に対応する実行制御を行なうと共に、表示制御部２０３が、表示装置１０を初期メニューの表示に復帰させる処理を実行する（ステップＳ１０７）。 Next, when the control device 20 takes in a selection (determination) signal from the operation input device 200 (determination operation detection unit 220), the display control unit 203, along with the selection (determination) information, via the operation information acquisition unit 201. Position information is taken in, and it is determined whether or not the menu items A to H (sector areas 511 to 518) displayed in the first display area indicated by the circle 510 have been selected (step S110). Here, when it is detected that any one of the menu items A to H (sector areas 511 to 518) displayed in the first display area is selected, the process returns to step S106, and the display control unit 203 is selected. If there is an n + 1 lower-level menu item associated with any of the menu items A to H (step S106), and if it is determined that there is no lower-level menu item (step S106 "YES"), Since the selection is the final selection, the process execution unit 204 performs execution control corresponding to the menu item, and the display control unit 203 executes a process of returning the display device 10 to the initial menu display (step S107).
　なお、ステップＳ１０３で、ラジアル操作メニュー５００（Ｖ）の中心Ｐから外周方向に向かってスワイプ（シフト）操作が行われていないことが検出された場合（ステップＳ１０３“ＮＯ”）、表示制御部２０３は、操作情報取得部２０１を介してその選択（決定）情報とともに位置情報を取り込んで、円５１０で示す第１の表示領域に表示したメニュー項目Ａ～Ｈが選択（決定）されたか否かを判定し（ステップＳ１１０）、選択され場合（ステップＳ１１０“ＹＥＳ”）、その選択が最終選択であれば（ステップＳ１０６“ＹＥＳ”）、処理実行部２０４が、そのメニュー項目に対応する実行制御を行なうと共に、表示制御部２０３が、表示装置１０を初期メニューの表示に復帰させる制御を行う（ステップＳ１０７）。 When it is detected in step S103 that no swipe (shift) operation is performed from the center P of the radial operation menu 500 (V) toward the outer periphery (“NO” in step S103), the display control unit 203 Indicates whether or not the menu items A to H displayed in the first display area indicated by the circle 510 are selected (determined) by taking the position information together with the selection (determination) information via the operation information acquisition unit 201. If it is determined (step S110) and selected (step S110 “YES”), and the selection is the final selection (step S106 “YES”), the process execution unit 204 performs execution control corresponding to the menu item. At the same time, the display control unit 203 performs control for returning the display device 10 to the display of the initial menu (step S107).
　すなわち、表示制御部２０３は、操作入力装置２００の円環状の操作面の押下操作（選択（決定）操作）を検出しながら触れるかなぞる（指定操作）ユーザ操作により、階層展開領域５２０で示す第２の表示領域に表示された第２の部分円（セクタ領域５２１～５２５）のそれぞれに割り当てたｎ＋１階層のメニュー項目の選択を有効にし、一方、操作面の押下を含まないユーザ操作を検出した場合、円５１０で示す第１の表示領域に表示された部分円（セクタ領域５１１～５１８）のそれぞれに割り当てたメニュー項目Ａ～Ｈの選択を有効にする。このことにより、指定された第１の部分円（セクタ領域５１２）の外周に、第２の部分円（階層展開領域５２０に配置されたセクタ領域５２１～５２５）のそれぞれが表示された状態で、いずれのメニュー項目の選択（決定）も可能になるため、目的とするｎ＋１階層の操作メニューに至るまでに各階層のメニュー項目を表示して選択（決定）するという、従来の冗長な操作が省け、直接的（かつ直観的）に、目的とするメニュー項目を表示させてそのメニュー項目を選択できることから迅速で効率的なメニュー項目の選択が可能になる。 In other words, the display control unit 203 detects the pressing operation (selection (decision) operation) of the annular operation surface of the operation input device 200 while detecting and touching (designating operation) by the user operation indicated by the hierarchical development area 520. The menu item of the n + 1 layer assigned to each of the second partial circles (sector areas 521 to 525) displayed in the display area 2 is enabled, and a user operation that does not involve pressing the operation surface is detected. In this case, the selection of the menu items A to H assigned to each of the partial circles (sector areas 511 to 518) displayed in the first display area indicated by the circle 510 is validated. As a result, the second partial circles (sector areas 521 to 525 arranged in the hierarchical development area 520) are displayed on the outer periphery of the designated first partial circle (sector area 512). Since any menu item can be selected (determined), the conventional redundant operation of displaying and selecting (determining) the menu items in each hierarchy before reaching the target n + 1 hierarchy operation menu can be omitted. Since the target menu item can be displayed directly (and intuitively) and the menu item can be selected, the menu item can be selected quickly and efficiently.
　なお、図６に示すフローチャートによれば、表示制御部２０３は、ユーザ操作（ユーザの指）が、円の中心から外周の方向に移動させる直観的な操作であるスワイプ（シフト）を行ったことを契機に、第２の部分円（階層展開領域５２０の各セクタ領域５２１～５２５）のそれぞれを、指定された第１の部分円（セクタ領域５１２）の外周に表示させる制御を行う場合について説明したが、スワイプ（シフト）のような直観的な操作によらず、ユーザの指が、メニュー項目Ｂが割り当てられた第１の部分円（セクタ領域５１２）に所定時間以上留まっているか、あるいは所定時間以上継続して触れているか、のいずれかを検出した場合に、第２の部分円（階層展開領域５２０のセクタ領域５２１～５２５）のそれぞれを、指定された第１の部分円（セクタ領域５１２）の外周に表示させる制御を行なってもよい。 In addition, according to the flowchart shown in FIG. 6, the display control unit 203 performs a swipe (shift), which is an intuitive operation in which the user operation (user's finger) moves from the center of the circle toward the outer periphery. As a trigger, a description will be given of a case where control is performed to display each of the second partial circles (the sector areas 521 to 525 of the hierarchical development area 520) on the outer periphery of the designated first partial circle (sector area 512). However, the user's finger stays in the first partial circle (sector area 512) to which the menu item B is assigned for a predetermined time or more, or without a predetermined operation such as swipe (shift). Each of the second partial circles (sector areas 521 to 525 of the hierarchical development area 520) is detected by the designated first It may be performed control to display on the outer circumference of the pie (sector region 512).
（変形例）
　以下、図８～図１０を参照して、更新されたラジアル操作メニュー５００（Ｖ）の変形例について説明する。図８に、第１の変形例を示す。第１の変形例では、画像生成部２０２は、指定された第１の部分円（メニュー項目Ｂが割り当てられているセクタ領域）の中心を基点に、半径方向に延びる２本の線がなす角度βと、第２の部分円（階層展開領域５２０）のそれぞれの中心を基点に半径方向に延びる２本の線がなす角度の合計（α１＋α２＋α３＋α４＋α５）とが等しくなるように設定し、更新されたラジアル操作メニューの画像を生成している。このとき、表示制御部２０３は、第２の部分円（階層展開領域５２０）のそれぞれを、指定された第１の部分円（メニュー項目Ｂが割り当てられているセクタ領域）の外周に並べて表示する制御を行なう。 (Modification)
Hereinafter, modified examples of the updated radial operation menu 500 (V) will be described with reference to FIGS. FIG. 8 shows a first modification. In the first modification, the image generation unit 202 forms an angle formed by two lines extending in the radial direction from the center of the designated first partial circle (sector area to which the menu item B is assigned). Radial updated by setting β to be equal to the sum (α1 + α2 + α3 + α4 + α5) formed by two lines extending in the radial direction from the center of each of the second partial circles (hierarchical expansion region 520). An operation menu image is generated. At this time, the display control unit 203 displays each of the second partial circles (hierarchy development area 520) side by side on the outer periphery of the designated first partial circle (sector area to which menu item B is assigned). Take control.
　第１の変形例によれば、指定されたメニュー項目Ｂが割り当てられた第１の部分円（メニュー項目Ｂが割り当てられているセクタ領域）の中心角βを拡大し、拡大した中心角βの角度範囲内に、第２の部分円（階層展開領域５２０）に割り当てたメニュー項目のそれぞれが整列して配置され、表示されるため、ユーザは、見映えの良いラジアル操作メニューを確認することができ、図７に示すラジアル操作メニュー５００（Ｖ）と比較して誤った選択（決定）操作の機会が減る。 According to the first modification, the central angle β of the first partial circle (sector area to which the menu item B is assigned) to which the designated menu item B is assigned is enlarged, and the enlarged central angle β is obtained. Since the menu items assigned to the second partial circle (hierarchy development area 520) are arranged and displayed within the angle range, the user may check a good-looking radial operation menu. This reduces the chance of erroneous selection (determination) operation compared to the radial operation menu 500 (V) shown in FIG.
　図９（ａ）（ｂ）に、更新されたラジル操作メニューの第２の変形例を示す。ここでは、図９（ａ）に示すように、ユーザが操作入力装置２００を操作し、階層展開領域５２０で示す第２の表示領域に表示されたｎ＋１階層に属する１以上のメニュー項目の一つを指定しようとして時計回りの方向に回転転操作（点線表記ｚ）を行なった場合に階層展開領域５２０で示す第２の表示範囲外に外れた場合を想定している。画像生成部２０２は、操作情報取得部２０１を介して取得される位置情報に基づき、ユーザの指の位置が、階層展開領域５２０の第２の表示領域の範囲外にあることを検出すると、図８（ｂ）に示すように、先に指定されたメニュー項目Ｂが割り当てられているセクタ領域５１２の時計回りの方向に隣接するメニュー項目Ｃに対応する、ｎ＋１階層に属する１以上のメニュー項目Ｃａ，Ｃｂ，Ｃｃ，Ｃｄ，Ｃｅのそれぞれを、メニュー項目Ｃが割り当てられているセクタ領域の外周の階層展開領域５２０ｂに配置して更新されたラジアル操作メニュー５００（Ｖ）を生成する。 FIGS. 9A and 9B show a second modification of the updated rasil operation menu. Here, as shown in FIG. 9A, one of one or more menu items belonging to the n + 1 hierarchy displayed in the second display area indicated by the hierarchy development area 520 when the user operates the operation input device 200. Is assumed to be out of the second display range indicated by the hierarchy development area 520 when a rotation operation (dotted line notation z) is performed in the clockwise direction in order to designate the position. When the image generation unit 202 detects that the position of the user's finger is outside the range of the second display area of the hierarchical development area 520 based on the position information acquired via the operation information acquisition unit 201, As shown in FIG. 8B, one or more menu items Ca belonging to the n + 1 hierarchy corresponding to the menu item C adjacent in the clockwise direction of the sector area 512 to which the previously designated menu item B is allocated. , Cb, Cc, Cd, and Ce are arranged in the hierarchical development area 520b on the outer periphery of the sector area to which the menu item C is allocated, thereby generating the updated radial operation menu 500 (V).
　そして、表示制御部２０３は、ユーザ操作（移動軌跡）に応じて、表示装置１０の第２の表示領域に表示すべき階層展開領域５２０の内容を更新する。すなわち、表示制御部２０３は、画像生成部２０２により生成された、更新されたラジアル操作メニュー５００（Ｖ）に基づき、メニュー項目Ｃが表示されているセクタ領域の外周に、メニュー項目Ｃに対応するｎ＋１階層のメニュー項目Ｃａ，Ｃｂ，Ｃｃ，Ｃｄ，Ｃｅ（階層展開領域５２０ｂ）を表示する制御を行う。 Then, the display control unit 203 updates the contents of the hierarchy development area 520 to be displayed in the second display area of the display device 10 in accordance with a user operation (movement locus). That is, the display control unit 203 corresponds to the menu item C on the outer periphery of the sector area where the menu item C is displayed based on the updated radial operation menu 500 (V) generated by the image generation unit 202. Control is performed to display menu items Ca, Cb, Cc, Cd, and Ce (hierarchy development area 520b) of the (n + 1) th hierarchy.
　第２の変形例によれば、ユーザの指の位置が、第２の部分円（階層展開領域５２０）の位置を外れると、指定された第１の部分円（メニュー項Ｂが割り当てられたセクタ領域）の時計回りか半時計回りの方向に隣接する第１の部分円（メニュー項目ＡかＣが割り当てられたそれぞれのセクタ領域）に対応するｎ＋１階層に属する１以上のメニュー項目から成る第２の部分円（階層展開領域５２０ｂ）のそれぞれが、隣接する第１の部分円（メニュー項Ａ又はＣが割り当てられたそれぞれのセクタ領域）の外周に表示される。したがって、例えば、誤操作があった場合に、最初から操作を再開することなく、自動的に隣接する第１の部分円（メニュー項目ＡかＣが割り当てられたそれぞれのセクタ領域）に対応する第２の部分円（階層展開領域５２０ｂ）のそれぞれが外周に表示されるため、冗長な操作の機会が減って目的とするメニュー項目があるか否かを一層迅速に知ることができ、効率的なメニュー項目の選択（決定）が可能になる。 According to the second modified example, when the position of the user's finger is out of the position of the second partial circle (hierarchy development area 520), the designated first partial circle (sector to which menu item B is assigned). A second item comprising one or more menu items belonging to the n + 1 hierarchy corresponding to a first partial circle (each sector region to which menu item A or C is assigned) adjacent in the clockwise or counterclockwise direction of (region). Of each partial circle (hierarchical development area 520b) is displayed on the outer periphery of the adjacent first partial circle (each sector area to which menu item A or C is assigned). Therefore, for example, when there is an erroneous operation, the second corresponding to the first partial circle (each sector area to which the menu item A or C is assigned) is automatically adjacent without restarting the operation from the beginning. Since each of the partial circles (hierarchy development area 520b) is displayed on the outer periphery, it is possible to know more quickly whether or not there is a target menu item by reducing the chance of redundant operation, and an efficient menu Items can be selected (determined).
　なお、図９（ｂ）に示す更新されたラジアル操作メニュー５００（Ｖ）の表示例では、時計回り方向に隣接するメニュー項目Ｃに対応する、ｎ＋１階層に属する１以上のメニュー項目を、メニュー項目Ｃが割り当てられているセクタ領域の外周に配置し、表示する例について説明したが、反時計回りの方向に隣接するメニュー項目Ａに対応する、ｎ＋１階層に属する１以上のメニュー項目を、メニュー項目Ａが割り当てられているセクタ領域の外周に配置し、表示してもよい。 In the display example of the updated radial operation menu 500 (V) shown in FIG. 9B, one or more menu items belonging to the n + 1 hierarchy corresponding to the menu item C adjacent in the clockwise direction are menu items. Although an example of arranging and displaying on the outer periphery of the sector area to which C is assigned has been described, one or more menu items belonging to the n + 1 hierarchy corresponding to the menu item A adjacent in the counterclockwise direction are displayed as menu items. It may be arranged and displayed on the outer periphery of the sector area to which A is allocated.
　図１０（ａ）（ｂ）に、更新されたラジアル操作メニュー５の第３の変形例を示す。ここでは、表示制御部２０３は、外部から取得される車両の車速情報に応じて、第２の部分円（階層展開領域５２０）に配置されるそれぞれのセクタ領域表示サイズを変更して、指定された第１の部分円（メニュー項目Ｂが割り当てられているセクタ領域）の外周に表示させる制御を行なう。ここでは、図１０（ｂ）に示すように、拡大された階層展開領域５２０ｃで示す第２の表示領域に、指定されたｎ階層に属するメニュー項目Ｂに対応するｎ＋１階層に属するメニュー項目のそれぞれが表示される。なお、車速情報は、入出力Ｉ／Ｆ３０を介して車載機器４００のうちのいずれからかＢＵＳ経由で取得するか、あるいは車両１の任意の場所に実装された加速度センサから出力される加速度情報を微分する等によって取得することができる。 10A and 10B show a third modification of the updated radial operation menu 5. FIG. Here, the display control unit 203 changes each sector area display size arranged in the second partial circle (hierarchical development area 520) according to the vehicle speed information acquired from the outside, and is designated. Further, control is performed to display on the outer periphery of the first partial circle (sector area to which menu item B is assigned). Here, as shown in FIG. 10B, each of the menu items belonging to the n + 1 hierarchy corresponding to the menu item B belonging to the designated n hierarchy is displayed in the second display area indicated by the expanded hierarchy development area 520c. Is displayed. The vehicle speed information is acquired from any of the in-vehicle devices 400 via the input / output I / F 30 or via the BUS, or acceleration information output from an acceleration sensor mounted at an arbitrary location of the vehicle 1. It can be obtained by differentiating.
　第３の変形例によれば、表示制御部２０３が、外部から取得される車両の車速情報に応じて、ｎ＋１階層に属するメニュー項目のそれぞれの表示サイズを変更して、ｎ階層に属するメニュー項目が割り当てられた第１の部分円（メニュー項目Ｂが割り当てられているセクタ領域）の外周に表示させる制御を行うため、例えば、車速が遅い場合、外周に表示される第２の部分円（階層展開領域５２０）のそれぞれの表示サイズを通常サイズとし（図１０（ａ））、車速が速い場合、外周に表示される第２の部分円（階層展開領域５２０ｃ）の表示サイズを拡大サイズとする（図１０（ｂ））ことで、車速に応じた前方の視野を確保することができ、安全運転に寄与することができる。 According to the third modification, the display control unit 203 changes the display size of each menu item belonging to the n + 1 hierarchy according to the vehicle speed information of the vehicle acquired from the outside, and the menu item belonging to the n hierarchy. For example, when the vehicle speed is low, the second partial circle (hierarchy) displayed on the outer periphery is controlled. Each display size of the development area 520) is set to the normal size (FIG. 10A), and when the vehicle speed is high, the display size of the second partial circle (tier development area 520c) displayed on the outer periphery is set to the enlarged size. (FIG. 10 (b)), it is possible to secure a forward visual field corresponding to the vehicle speed and contribute to safe driving.
（実施形態の効果）
　以上説明のように本実施形態の車両用メニュー表示制御装置３００によれば、ｎ階層（ｎは２以上の任意の整数）に属するメニュー項目を割り当てた第１の部分円の周辺に、指定されたメニュー項目の一つに対応するｎ＋１階層に属する１以上のメニュー項目を割り当てた第２の部分円を表示するＧＵＩ環境を提供することができる。このため、ユーザ（車両の運転者等）は、ｎ階層のメニュー項目を選択（決定）操作する前に、指定されたｎ階層に属するメニュー項目に対応するｎ＋１階層のメニュー項目を確認することができる。したがって、ユーザは、目的とするｎ＋１階層のメニュー項目に至るまでに階層毎に対応するメニュー項目を表示して選択（決定）するという、従来の冗長な操作を行う必要がない。言い換えると、車両用メニュー表示制御装置は、目的とするメニュー項目が含まれる下位階層のメニュー項目を、指定された上位階層のメニュー項目が割り当てられた部分円の外周に配置して表示させる制御を行うことで、ユーザは、下位階層のメニュー項目の中に、直接的（かつ直観的）に目的とするメニュー項目があるか否かを知ることができ、そのメニュー項目を選択（決定）操作することができる。したがって、迅速で効率的なメニュー項目の選択が可能になり、操作性や使い勝手の向上を図ることができる。 (Effect of embodiment)
As described above, according to the vehicle menu display control device 300 of the present embodiment, the menu item is specified around the first partial circle to which the menu item belonging to the n hierarchy (n is an arbitrary integer of 2 or more) is assigned. It is possible to provide a GUI environment that displays a second partial circle to which one or more menu items belonging to the (n + 1) layer corresponding to one of the menu items is assigned. For this reason, the user (a vehicle driver or the like) may check the menu item in the n + 1 hierarchy corresponding to the menu item belonging to the designated n hierarchy before selecting (deciding) the menu item in the n hierarchy. it can. Therefore, the user does not need to perform the conventional redundant operation of displaying and selecting (determining) the menu item corresponding to each hierarchy before reaching the target menu item of the (n + 1) th hierarchy. In other words, the vehicle menu display control device performs control to arrange and display the lower-level menu item including the target menu item on the outer periphery of the partial circle to which the designated upper-level menu item is assigned. By doing so, the user can know whether or not the target menu item is directly (and intuitively) in the lower-level menu items, and selects (determines) the menu item. be able to. Therefore, menu items can be selected quickly and efficiently, and operability and usability can be improved.
　また、本実施形態の車両用メニュー表示制御装置３００によれば、選択した第１の部分円を基準に時計回り又は反時計回りの方向に対応する第２の部分円のそれぞれが表示されるため、ユーザ（車両１の運転者等）は、外周に表示された第２の部分円に割り当てたそれぞれメニュー項目が、指定された第１の部分円のどのメニュー項目に対応しているかの認識が容易になる。また、指定された部分円の外周に表示される第２の部分円と、車両の前方の前景とが重なる表示領域を最小限に抑えることができるため、非表示の表示領域に対応する部分の前方視野を確保でき、その結果、安全運転に寄与することができる。これは、特に、バックライト光源により透過表示を行う液晶表示装置（ＬＣＤ）等によりメニュー項目を示す表示像を生成し、虚像としてウインドシールド（フロントガラス）に照射し、この虚像を車両の前方の実景と重ねてユーザ（車両の運転者等）に視認させるヘッドアップディスプレイを表示装置として用いた場合に有効である。 In addition, according to the vehicle menu display control device 300 of the present embodiment, each of the second partial circles corresponding to the clockwise or counterclockwise direction is displayed based on the selected first partial circle. The user (such as the driver of the vehicle 1) recognizes which menu item assigned to the second partial circle displayed on the outer periphery corresponds to which menu item in the designated first partial circle. It becomes easy. In addition, since the display area where the second partial circle displayed on the outer periphery of the designated partial circle and the foreground in front of the vehicle overlap can be minimized, the portion corresponding to the non-display area is displayed. A front view can be secured, and as a result, it can contribute to safe driving. In particular, a display image showing menu items is generated by a liquid crystal display (LCD) or the like that performs transmissive display using a backlight light source, and is irradiated onto a windshield (front glass) as a virtual image. This is effective when a head-up display that is visually recognized by a user (such as a driver of a vehicle) superimposed on a real scene is used as a display device.
　また、本実施形態の車両用メニュー表示制御装置３００によれば、ユーザの指が第１の部分円の中心から外周の方向に移動したか、第１の部分円の領域に所定時間以上留まっているか、第１の部分円の領域を所定時間以上継続して触れているか、の一つを検出したことを契機に、ｎ階層に属するメニュー項目を割り当てた第１の部分円の周辺に、指定されたメニュー項目の一つに対応するｎ＋１階層に属する１以上のメニュー項目を割り当てた第２の部分円を表示するため、特に、ユーザの指が第１の部分円の中心から外周の方向に移動させる直観的な操作を行ったことを契機に、第２の部分円のそれぞれを指定された第１の部分円の外周に表示させる制御を行う場合に対応するメニュー項目を迅速に表示することができ、操作性や使い勝手がより向上する。 Further, according to the vehicle menu display control device 300 of the present embodiment, the user's finger has moved from the center of the first partial circle toward the outer periphery, or stayed in the first partial circle area for a predetermined time or more. Or if the area of the first partial circle is continuously touched for a predetermined time or longer, it is specified around the first partial circle to which the menu item belonging to the n hierarchy is assigned. In order to display a second partial circle to which one or more menu items belonging to the (n + 1) hierarchy corresponding to one of the menu items assigned is displayed, the user's finger is particularly directed from the center of the first partial circle toward the outer periphery. Quickly display the corresponding menu items when performing control to display each of the second partial circles on the outer circumference of the designated first partial circle, triggered by an intuitive operation to move Operability and usability There is further improved.
　また、本実施形態の車両用メニュー表示制御装置３００によれば、操作面の押下操作（選択（決定）操作）を検出しながら触れるかなぞる（指定操作）ユーザ操作により、第２の部分円のそれぞれに割り当てたｎ＋１階層のメニュー項目の選択を有効にし、操作面の押下を含まないユーザ操作を検出した場合、部分円のそれぞれに割り当てたメニュー項目の選択を有効にするため、指定された第１の部分円の外周に第２の部分円のそれぞれが表示された状態でいずれのメニュー項目の選択（決定）も可能となり、目的とするｎ＋１階層の操作メニューに至るまでに各階層のメニュー項目を表示して選択（決定）するという、従来の冗長な操作が省け、直接的（かつ直観的）に、目的とするメニュー項目を表示させてそのメニュー項目を選択できることから迅速で効率的なメニュー項目の選択が可能になる。 In addition, according to the vehicle menu display control device 300 of the present embodiment, the second partial circle of the second partial circle can be detected by a user operation (designation operation) by touching while detecting a pressing operation (selection (decision) operation) on the operation surface. When the selection of the menu item assigned to each of the n + 1 layers is enabled and a user operation that does not include pressing the operation surface is detected, the selection of the menu item assigned to each of the partial circles is enabled. Any menu item can be selected (determined) in a state where each of the second partial circles is displayed on the outer periphery of the partial circle of 1, and the menu items of each layer until the target operation menu of n + 1 layers is reached. The conventional redundant operation of displaying and selecting (determining) is omitted, and the desired menu item is displayed directly (and intuitively) and the menu item is selected. The selection of fast and efficient menu item from the fact that you can become possible.
　また、本実施形態の車両用メニュー表示制御装置３００によれば、例えば、移動速度が所定の閾値と比較して遅いと判定された場合、第２の部分円のそれぞれに割り当てられているｎ＋１階層のメニュー項目を選択しようとしていると判定することで、指定された第１の部分円の外周に第２の部分円のそれぞれが表示された状態でいずれのメニュー項目の選択（決定）も可能になる。したがって、目的とするｎ＋１階層の操作メニューに至るまでに各階層のメニュー項目を表示して選択（決定）するという、従来の冗長な操作が省け、直接的（かつ直観的）に、目的とするメニュー項目を表示させてそのメニュー項目を選択できることから迅速で効率的なメニュー項目の選択が可能になる。 Further, according to the vehicle menu display control apparatus 300 of the present embodiment, for example, when it is determined that the moving speed is slower than a predetermined threshold, the n + 1 hierarchy assigned to each of the second partial circles It is possible to select (determine) any menu item in a state where each of the second partial circles is displayed on the outer periphery of the designated first partial circle by determining that the menu item is selected. Become.
