Abstract

Even if the driver of the vehicle accidentally selects an operation item from an operation menu having a hierarchical structure, this invention enables efficiently selecting the correct operation item without the lengthy operation of going back a level in the hierarchy. This operation menu control device for a vehicle is provided with an operation menu image generation unit 22 and an operation menu display processing unit 24 which performs display processing of a generated operation menu image. When, as a result of the selection of one operation item included in an nth level operation menu (n being a natural number greater than or equal to 1), an image is generated of an (n+1)st level operation menu associated with the selected one operation item, the operation menu image generation unit 22 generates an image of the (n+1)st level operation menu, which includes multiple regular operation items for the (n+1)st level, and a shortcut item, which is an operation item contained in the nth level operation menu other than the selected one operation item.

Description

車両用操作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 operation 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操作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, for example, a vehicle operation menu display control device mounted on a vehicle such as an automobile, an in-vehicle device operation system, a GUI program, and the like.
 GUI(グラフィカルユーザーインターフェース)は、マウスなどのポインティングデバイスを使用して、直感的にコンピュータを操作できるようにしたヒューマンインターフェース技術の一種であり、従来、GUIを用いて階層構造をもつメニューを表示し、多数の項目の中から所望の項目を効率的に選択できるようにすることが知られている。 A GUI (Graphical User Interface) is a type of human interface technology that makes it possible to intuitively operate a computer using a pointing device such as a mouse, and conventionally displays a menu with a hierarchical structure using a GUI. It is known to be able to efficiently select desired items from among a large number of items.
 階層構造をもつメニュー(階層化メニュー)において、ユーザーが項目の選択を誤った場合には、一般的には、現在の階層を1つ前の上位階層に戻して、再度、項目を選択する必要があるが、従来、このような階層を戻す処理をする必要のない階層化メニューの表示についても提案されている(例えば、特許文献1、特許文献2)。 In a menu with hierarchical structure (hierarchical menu), if the user makes an incorrect selection of an item, generally, it is necessary to move the current hierarchy back to the previous hierarchy and select the item again. In the prior art, it has also been proposed to display hierarchical menus that do not require processing to return such a hierarchy (for example, Patent Document 1 and Patent Document 2).
 特許文献1、2は、上位階層メニューと下位階層メニューとを、1つの画面に併存させるという点で共通する。下位階層メニューが表示されている状態でも、その横に上位階層メニューも併せて表示されていることから、選択の誤りに気付いたユーザーは、上位階層メニューを直接的に操作して、正しい下位階層メニューを表示させることができる。 Patent documents 1 and 2 are common in the point that a high-order hierarchy menu and a low-order hierarchy menu are coexisted on one screen. Even when the lower-level menu is displayed, the upper-level menu is also displayed next to it, so the user who notices an incorrect selection directly operates the upper-level menu to correct the lower-level menu. A menu can be displayed.
 また、GUIを用いてブラインド操作を可能とした車載機器操作システムについては、例えば、特許文献3に記載されている。 Moreover, about the vehicle-mounted apparatus operation system which enabled blind operation using GUI, it describes in patent document 3, for example.

 ハンドル(例えばステアリングホイール)を握って車両を運転している運転者は、前方を注視しつつ、必要に応じてメニュー画像を表示させて、極めて短時間で項目を選択する必要がある。この点を考慮すると、特許文献1、2のように、上位、下位の各階層メニューを併存させて表示する方式は、画面構成が複雑で見づらく、項目選択にも時間を要すると考えられ、車載機器等についての操作項目を選択する用途には不向きである。 A driver who is driving a vehicle by holding a steering wheel (for example, a steering wheel) needs to select an item in a very short time by displaying a menu image as needed while gazing forward. If this point is taken into consideration, as in Patent Documents 1 and 2, it is considered that the method of displaying the upper and lower hierarchy menus in parallel with each other is complicated because the screen configuration is complicated and difficult to see, and it takes time for item selection. It is unsuitable for the use which selects the operation item about apparatus etc.
 また、特許文献3では、車載機器をブラインド操作することはできるが、ユーザー(運転者等)が項目の選択を誤り、意図しない下位の操作メニューが表示されてしまったときには、従来どおり、階層を戻して、操作項目の選択をやり直すという冗長な操作が必要であり、この点、ユーザー(運転者等)の負担は軽減されていない。 Further, in Patent Document 3, although it is possible to blindly operate the in-vehicle device, when the user (driver or the like) erroneously selects an item and an unintended lower operation menu is displayed, the hierarchy is It is necessary to return to the redundant operation of reselecting the operation item, and the burden on the user (driver, etc.) is not alleviated.
 本発明は、車両のユーザー(例えば運転者)が、階層構造を有する操作メニューの操作項目を誤って選択した場合でも、階層を戻すという冗長な操作をすることなく、正しい操作項目を効率的に選択できるようにすることを目的とする。 According to the present invention, even when a user of a vehicle (for example, a driver) mistakenly selects an operation item of an operation menu having a hierarchical structure, the correct operation item can be efficiently performed without performing a redundant operation of returning the hierarchy. It is intended to be selectable.
 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 following exemplified aspects and best embodiments, as well as the attached drawings.
 以下に、本発明の概要を容易に理解するために、本発明に従う態様を例示する。 In the following, in order to facilitate an understanding of the summary of the invention, an embodiment according to the invention is illustrated.
 第1の態様において、車両用操作メニュー表示制御装置は、
 階層構造を有すると共に、1つの階層の画像に複数の操作項目が含まれる操作メニューの表示を制御する車両用操作メニュー表示制御装置であって、
 前記操作メニューの画像を生成する操作メニュー画像生成部と、
 生成された操作メニューの画像の表示処理を行う表示処理部と、
を有し、
 前記操作メニュー画像生成部は、
 前記選択信号によって第n階層(nは1以上の自然数)の操作メニューに含まれる1つの操作項目が選択された結果として、選択された前記1つの操作項目に関連付けられた第(n+1)階層の操作メニューの画像を生成する場合に、第(n+1)階層用の正規の複数の操作項目と、前記n階層の操作メニューに含まれていた、前記選択された1つの操作項目以外の操作項目であるショートカット用項目と、を含む、第(n+1)階層の操作メニューの画像を生成する。
In the first aspect, the vehicle operation menu display control device includes:
A vehicle operation menu display control device having a hierarchical structure and controlling display of an operation menu including a plurality of operation items in an image of one layer,
An operation menu image generation unit that generates an image of the operation menu;
A display processing unit that performs display processing of the generated image of the operation menu;
Have
The operation menu image generation unit
As a result of selection of one operation item included in the operation menu of the nth layer (n is a natural number of one or more) by the selection signal, the (n + 1) th layer associated with the selected one operation item In the case of generating an image of the operation menu, the operation items other than the one selected operation item included in the operation menu for the (n + 1) th layer and the operation menu of the nth layer An image of the operation menu of the (n + 1) -th layer including a certain shortcut item is generated.
 第1の態様では、下位階層の操作メニュー(正規の下位階層の操作項目を含む)に、上位階層の操作メニューの操作項目のうち、先に選択された操作項目を除く、他の操作項目の少なくとも1つを、ショートカット用項目として含ませておく。 In the first mode, in the operation menu of the lower hierarchy (including the operation items of the regular lower hierarchy), of the operation items of the operation menu of the upper hierarchy except for the operation item selected in advance, Include at least one item as a shortcut item.
 上位階層の操作メニューから下位階層の操作メニューへと移行したときに、誤りに気付いたユーザー(車両の運転者や同乗者等)は、ショートカット用項目を選択することで、上位階層に戻した後に所望の項目を選択し直したのと同じ効果を得ることができる。この場合、上位階層に戻す処理を省いて最短の選択ができる(言い換えれば、近道(ショートカット)をすることができる)ことから、冗長的な処理を省いて、迅速で効率的、かつ快適な選択操作が可能である。 When switching from the operation menu of the upper hierarchy to the operation menu of the lower hierarchy, a user who noticed an error (such as a driver or a passenger of a vehicle) selects an item for shortcut after returning to the upper hierarchy. The same effect as reselecting the desired item can be obtained. In this case, since the process of returning to the upper layer can be omitted and the shortest selection can be made (in other words, the shortcut can be made), the redundant process is omitted, and the selection is quick, efficient, and comfortable. Operation is possible.
 車載に適したポインティングデバイスとしての選択装置を開発することで、ユーザー(運転者等)がブラインドタッチで操作項目を選択できるようにはなるが、その精度は、机上でマウス等を操作してディスプレイの画面上で項目を選択するような既存のコンピュータシステムと比較して、低いのは否めない。しかし、本態様によれば、ユーザーは、仮に選択に失敗しても、次の階層の操作メニューで正しい選択をすればよいので、常に正しい選択をしなければならない、という緊張感や不安感から解放され、戻らずに、前に進むという積極的選択で、ストレスなく選択を進めることができ、ユーザーの利便性は大きく向上する。このことは、例えば、車載機器をブラインドタッチで操作する、実用性のある車載機器操作システムの実現に貢献する。 By developing a selection device as a pointing device suitable for in-vehicle use, the user (driver, etc.) can select operation items by blind touch, but its accuracy is displayed by operating a mouse etc. on a desk Compared to existing computer systems such as selecting items on the screen, it is undeniable that it is low. However, according to the present embodiment, even if the user fails in selection, the user can always make the correct selection in the operation menu of the next layer, and therefore, he feels nervous and anxious that he must always make the correct selection. With the positive selection of being released, not returning, and moving forward, the selection can be made without stress and the convenience of the user is greatly improved. This contributes, for example, to the realization of a practical on-vehicle device operation system for operating the on-vehicle device by blind touch.
 第1の態様に従属する第2の態様において、
 前記操作メニュー画像生成部が生成する前記第(n+1)階層の操作メニューの画像に含まれる前記ショートカット用項目は、前記第n階層の操作メニューにおける前記選択された1つの操作項目に隣接して配置されていた、少なくとも1つの操作項目であるようにしてもよい。
In a second aspect dependent on the first aspect,
The item for shortcut included in the image of the operation menu of the (n + 1) layer generated by the operation menu image generation unit is arranged adjacent to the selected operation item in the operation menu of the nth layer Alternatively, at least one operation item may be set.
 第2の態様では、上位階層の操作メニューにおいて、先に選択した操作項目(言い換えれば、操作項目アイコンや操作項目ボタンである。これらを総称する場合は、操作項目キーと称することができる)に隣接して配置されていた、少なくとも1つの操作項目を、下位階層の操作メニューに含ませるショートカット用項目とする。 In the second mode, in the operation menu of the upper hierarchy, the previously selected operation item (in other words, an operation item icon or an operation item button. When these are generically referred to, it can be called an operation item key) At least one operation item arranged adjacent to each other is set as a shortcut item to be included in the operation menu of the lower hierarchy.
 選択を誤る場合としては、一般的には、所望の操作項目を選ぼうとして、その隣に位置する操作項目を誤って選んでしまった(より具体的には、例えば、ポインティングデバイスとして機能する選択装置を、ブラインドタッチで操作して操作項目を選択する際に、選択位置を誤って、隣に位置する操作項目を選んでしまった)という場合が多いと考えられる。よって、上位階層の操作メニューにおいて、先に選択した操作項目に隣接していた操作項目をショートカット用項目とすることで、ユーザーが、本来、選択を望んだであろう操作項目を、下位階層の操作メニュー内で選択できるようになる。したがって、ショートカット機能を有効活用できる可能性が高まる。 In the case of incorrect selection, in general, an attempt is made to select a desired operation item, and an operation item located next to it is mistakenly selected (more specifically, for example, selection to function as a pointing device) When the user operates the device with a blind touch to select an operation item, it is considered that in many cases the selection position is mistakenly mistaken to select the operation item located next to the device. Therefore, by setting the operation item adjacent to the previously selected operation item as the shortcut item in the operation menu of the upper hierarchy, the operation item that the user would normally desire to select can be It can be selected in the operation menu. Therefore, the possibility of effectively utilizing the shortcut function is increased.
 第1の態様に従属する第3の態様において、
 前記操作メニュー画像生成部が生成する前記第(n+1)階層の操作メニューの画像には、
 前記ショートカット用項目としての、前記第n階層の操作メニューにおける前記選択された1つの操作項目に隣接して配置されていた、少なくとも1つの操作項目と、
 前記ショートカット用項目を選択する際の位置的基準を与える位置基準用項目としての、前記第n階層の操作メニューにおける前記選択された1つの操作項目と、が含まれるようにしてもよい。
In a third aspect dependent on the first aspect,
For the image of the operation menu of the (n + 1) -th layer generated by the operation menu image generation unit,
At least one operation item arranged adjacent to the selected one operation item in the operation menu of the n-th hierarchy as the item for shortcut;
The selected one operation item in the operation menu of the n-th hierarchy may be included as a position reference item for giving a positional reference when selecting the shortcut item.
 第3の態様では、第2の態様と同様に、上位階層の操作メニューにおいて、先に選択した操作項目に隣接していた操作項目をショートカット用項目とするが、さらに、先に選択した操作項目も、ショートカット用項目を選択する際の位置的基準を与える位置基準用項目として追加しておく。 In the third mode, as in the second mode, in the operation menu of the upper hierarchy, the operation item adjacent to the previously selected operation item is set as the shortcut item, but further, the operation item selected earlier Also, it is added as a position reference item which gives a positional reference when selecting a shortcut item.
 例えば、上位階層の操作メニューにて、「A、B、C」という3つの操作項目が表示され、操作項目Bが選択されたとき、下位階層の操作メニューとして、「α、β、A、B、C、γ、Δ」を表示する。ここで、α、β、γ、Δは、下位階層の正規(本来)の操作項目である。また、A、Cは、選択を誤ったときに近道をするためのショートカット用項目である。また、Bは、ショートカット用項目A又はCを選択する際に、位置的基準を与える位置基準用項目である。 For example, when three operation items “A, B, C” are displayed in the operation menu of the upper hierarchy and the operation item B is selected, “α, β, A, B” is displayed as the operation menu of the lower hierarchy. , C, γ, Δ ”. Here, α, β, γ and Δ are normal (intrinsic) operation items of the lower layer. Also, A and C are shortcut items for making a shortcut when the selection is incorrect. Further, B is a position reference item for giving a positional reference when selecting the shortcut item A or C.
 ユーザーは、上位階層の操作メニューにて、「A、B、C」という操作項目の配列を目にしており、A及びCは、選択したBに隣接していた、ということを記憶している。よって、次の下位階層にて、A又はCを選ぶときも、AとCの間にBがあった方が、ユーザーは相対的位置関係が明確で選びやすく、また、現在選択している操作項目がBである、という事実(言い換えれば、選択履歴)も明確化され、この点でもユーザーにとっては使い勝手がよい。よって、位置基準用項目の追加によって、ショートカット用項目を選択する際に、ユーザーが感じる違和感や不安感等を軽減することができる。 The user sees an array of operation items “A, B, C” in the operation menu of the upper hierarchy, and stores that A and C were adjacent to the selected B. . Therefore, even when selecting A or C in the next lower hierarchy, if there is B between A and C, the relative positional relationship is clear and easy for the user to select, and the operation currently selected The fact that the item is B (in other words, the selection history) is also clarified, which is convenient for the user. Therefore, when the item for shortcut is selected, the addition of the item for position reference can reduce the sense of incongruity and anxiety felt by the user.
 第3の態様に従属する第4の態様において、
前記第(n+1)階層の操作メニューの画像における、前記位置基準用項目に対する、前記ショートカット用項目の、配置方向についての相対的位置関係は、
 前記第n階層の操作メニューの画像における、前記選択された1つの操作項目に対する、前記隣接して配置されていた少なくとも1つの操作項目の、配置方向についての相対的位置関係と同じであるようにしてもよい。
In a fourth aspect dependent on the third aspect,
The relative positional relationship of the shortcut item with respect to the position reference item in the image of the operation menu of the (n + 1) -th layer with respect to the arrangement direction is
The relative positional relationship of the at least one operation item arranged adjacent to the selected one operation item in the image of the operation menu of the n-th hierarchy is the same as the arrangement direction with respect to the arrangement direction. May be
 第4の態様では、ショートカット用項目の配置に関して、配置方向についての相対的位置関係を、上位階層の操作メニューにおけるものと同じに保つことで、上位階層の操作メニューから下位階層の操作メニューへと遷移した場合に、ユーザーに違和感が生じないようする。 In the fourth aspect, with regard to the arrangement of the shortcut items, by keeping the relative positional relationship in the arrangement direction the same as that in the operation menu of the upper hierarchy, from the operation menu of the upper hierarchy to the operation menu of the lower hierarchy In the case of transition, the user is not made to feel uncomfortable.
 例えば、上位階層の操作メニューにて、「A、B、C」という3つの操作項目が表示され、操作項目Bが選択されたとき、下位階層の操作メニューとして、「α、β、A、B、γ、B、Δ」が表示されたとする。ここで、上位階層の操作メニューにおける「A」は、選択された操作項目「B」の左方向に位置し、「C」は、「B」の右方向に位置する。下位階層の操作メニューの、「α、β、A、B、γ、C、Δ」においても、ショートカット用項目「A」は「B」の左方向に位置し、「C」は、「B」から見て、「γ」を挟んではいるものの、右方向に位置する点は変わりがない。言い換えれば、ショートカット用項目「A」、「C」の、位置基準用項目「B」に対する、配置方向についての相対的位置関係は、上位階層の操作メニューにおける相対的位置関係と同じに保たれている。よって、ユーザーは、ショートカット用項目を選択する場合においても、違和感を覚えることがなく、快適な操作項目の選択が可能である。 For example, when three operation items “A, B, C” are displayed in the operation menu of the upper hierarchy and the operation item B is selected, “α, β, A, B” is displayed as the operation menu of the lower hierarchy. , Γ, B, Δ ”are displayed. Here, “A” in the operation menu of the upper hierarchy is located in the left direction of the selected operation item “B”, and “C” is located in the right direction of “B”. The shortcut item "A" is located in the left direction of "B" and "C" is "B" also in "α, β, A, B, γ, C, Δ" of the lower-level operation menu. From the point of view, although the point “γ” is sandwiched, the point positioned to the right remains the same. In other words, the relative positional relationship of the shortcut items "A" and "C" with respect to the arrangement direction with respect to the position reference item "B" is kept the same as the relative positional relationship in the operation menu of the upper hierarchy. There is. Therefore, even when the user selects the item for shortcut, the user can select a comfortable operation item without feeling discomfort.
 第3の態様に従属する第5の態様において、
 前記操作メニュー画像生成部は、
 最上位の階層である第1階層の操作メニューの画像を生成する際、所定の外形をもつメニュー全体の表示領域を、m個(mは2以上の自然数)の操作項目の表示用領域で分割して構成されてなる操作メニューの画像を生成し、
 第1階層の操作メニューの画像に含まれる1つの操作項目が選択されて、その選択された1つの項目に関連付けされた第2階層の操作メニューを生成する際、
 前記第2階層の操作目メニューの画像においても、前記所定の外形をもつメニュー全体の表示領域は維持し、かつ、前記第1階層において選択された操作項目の表示用領域に相当する、同形状で同サイズの領域を、前記メニュー全体の表示領域に対する位置関係をそのまま維持しつつ設けると共に、

In a fifth aspect dependent on the third aspect,
The operation menu image generation unit
When generating an image of the operation menu of the first hierarchy which is the top hierarchy, the display area of the whole menu having a predetermined outer shape is divided into m (m is a natural number of 2 or more) operation display areas for display items Generate an image of the operation menu configured
When one operation item included in the image of the operation menu of the first hierarchy is selected to generate the operation menu of the second hierarchy associated with the selected one item,
In the image of the operation menu of the second hierarchy, the display area of the whole menu having the predetermined outer shape is maintained, and the same shape corresponding to the display area of the operation item selected in the first hierarchy While providing the same size area while maintaining the positional relationship of the whole menu to the display area as it is,
The item for the reference position is provided in the area of the same shape and the same size,
Of the rules for providing the item for shortcut, the item for shortcut is provided adjacent to the item for reference position in the area of the same shape and size, or adjacent to the area of the same shape and size. At least one may be provided to be satisfied.
 第5の態様では、最上位階層である第1階層の操作メニューから、次の階層である第2階層の操作メニューに遷移する場合を例にとって、ショートカット用項目についての、好ましい配置規則を記載している。 In the fifth aspect, the preferred arrangement rule for the item for shortcut is described taking the case of transition from the operation menu of the first hierarchy which is the top hierarchy to the operation menu of the second hierarchy which is the next hierarchy as an example ing.
 例えば、下位階層の操作メニューの表示に際して、先に選択した操作項目(位置基準用項目)の近くに、集中的にショートカット用項目を配置したとすると、選択が誤りであった場合には、ユーザーは、例えば、指や手を大きく動かすことなく選択装置(ポインティングデバイス)を操作して、ショートカット用項目を選択でき、失敗からの回復は迅速に行える。しかし、選択が成功であったとき、正規(本来)の下位階層項目は、ショートカット用項目の外側に配置されることから、その選択のためには、ユーザーは、指や手を、ショートカット用項目の選択のときよりも、大きく動かす必要が生じる。したがって、より好ましくは、選択の失敗/成功にかかわらず、どちらの場合であっても、少ない指や手の動きで所望の操作項目を選択できるようにするのがよい。 For example, assuming that the shortcut items are intensively arranged near the previously selected operation item (position reference item) when displaying the operation menu of the lower hierarchy, if the selection is incorrect, the user For example, an item for shortcut can be selected by operating the selection device (pointing device) without much movement of the finger or hand, and recovery from failure can be performed quickly. However, when the selection is successful, the regular (intrinsic) lower-level items are placed outside the items for shortcut, so for the selection, the user selects the item for finger or hand, the item for shortcut There is a need to move more than when selecting. Therefore, more preferably, regardless of selection failure / success, it is preferable to be able to select a desired operation item with few finger and hand movements in either case.
 これを可能とする配置例としては、ショートカット用項目を少し分散させて配置し、その結果として生じる、先に選択した操作項目(位置基準用項目)の近くのスペース(空白領域)に、正規(本来)の下位階層の操作項目の優先順位の高いものを配置する、といった工夫をする(言い換えれば、正規の操作項目のいくつかを位置基準用項目の近くに配置し、一方、ショートカット用項目も、同じように位置基準用項目の近くに配置し、両項目のバランスをとって配置するという工夫をする)ことが好ましい。 As an example of arrangement that makes this possible, the items for shortcut are arranged slightly dispersed, and the resulting space (blank area) near the previously selected operation item (item for position reference) Inherently arrange the lower priority operation items in the lower hierarchy) (in other words, arrange some of the normal operation items near the position reference items, while also setting the shortcut items) In the same way, it is preferable to arrange them near the position reference items and to arrange the items in a balanced manner).
 例えば、上位階層の操作メニューにて、所定面積の横長の長方形を3等分して得られる各区画エリア「○、△、□」の各々に、「A、B、C」という3つの操作項目の各々を配置したとする。このとき、「項目自体」に着目すると、A、Cは、Bに隣接する、ということになり、ユーザーはこのことを記憶するが、また、見方を変えて、表示領域に着目すると、Aの表示領域である「○」、Cの表示領域である「□」は、Bの表示領域である「△」に隣接する、ということになり、ユーザーは、このような、表示領域についての位置関係も記憶する可能性が高い。次の下位階層の操作メニューにおけるショートカット用項目の配置として、項目自体に着目した相対的位置関係の規則のみではなく、表示領域についての位置関係を考慮した配置も許可することで、配置のバリエーションが増え、上記の、ショートカット用項目を少し分散させて配置することができる。 For example, in the operation menu of the upper hierarchy, three operation items of “A, B, C” in each of the divided areas “△, Δ, □” obtained by dividing the horizontally long rectangle of a predetermined area into three equal parts Let's say that each of the At this time, focusing on the item itself, A and C are adjacent to B, and the user stores this, but changing the way of thinking and focusing on the display area, A The display area “o” and the display area “C” are adjacent to the display area “B”, and the user is aware of the positional relationship with the display area. It is also likely to remember. As the arrangement of the shortcut items in the operation menu of the next lower hierarchy, not only the rule of relative positional relationship focusing on the items themselves, but also the arrangement considering the positional relationship about the display area is permitted, and the variation of the arrangement is In addition, the above-described items for shortcuts can be arranged slightly dispersed.
 具体例としては、例えば、上記「B」が選択されたとき、上記「△」の表示領域を三等分して得られる各区画エリア「◎、▽、◇」に、「B(位置基準用項目)、α(正規項目)、β(正規項目)」を配置し、その外側に隣接して、ショートカット用項目であるA、Cを配置する。この結果、『A、「B、α、β」、C』という配列ができる。この場合、正規の項目である「α、β」は、位置基準用項目Bに隣接して(あるいは、その近傍に)あり、一方、ショートカット用項目であるA及びC(特にC)は、上位階層の操作メニューにおける「B」の表示領域「Δ」(上記の下位階層の配列において「」で示されている)に隣接しており、上位階層との相対的位置関係は保たれている。このように、選択の失敗/成功の何れであっても、できるだけ効率的に所望の項目を選択できる配列が実現される。 As a specific example, for example, when the above “B” is selected, each section area “◎, 、, ◇” obtained by dividing the display area of “Δ” into three equal parts, “B (for position reference Item), α (regular item), β (regular item) ”are arranged, and items A and C as shortcut items are arranged adjacent to the outside thereof. As a result, the sequence “A,“ B, α, β ”, C” is formed. In this case, the regular items “α, β” are adjacent to (or in the vicinity of) the position reference item B, while the short-cut items A and C (especially C) are high-order items. It is adjacent to the display area ".DELTA." (Indicated by "" in the above-mentioned lower layer array) in the operation menu of the layer, and the relative positional relationship with the upper layer is maintained. In this way, an array is realized that allows the user to select the desired item as efficiently as possible, regardless of selection failure / success.
 第1乃至第4の何れか1つの態様に従属する第6の態様において、
 前記操作メニュー画像生成部が生成する前記第(n+2)階層の操作メニューの画像に含まれる前記ショートカット用項目には、
 前記第n階層の操作メニューにおける前記選択された1つの操作項目に隣接して配置されていた、少なくとも1つの操作項目と、
 前記第(n+1)階層の操作メニューにおいて選択された1つの操作項目に隣接して配置されていた、少なくとも1つの操作項目と、
 が含まれるようにしてもよい。
In a sixth aspect dependent on any one of the first to fourth aspects,
The shortcut items included in the image of the operation menu of the (n + 2) -th layer generated by the operation menu image generation unit include:
At least one operation item arranged adjacent to the selected one operation item in the operation menu of the nth hierarchy;
At least one operation item arranged adjacent to one operation item selected in the operation menu of the (n + 1) -th layer;
May be included.
 第6の態様では、上位階層(n階層)の操作メニューから、2階層分、階層が深化した場合((n+2)階層の操作メニューとなった場合)において、(n+2)階層の操作メニューに、直近の上位階層である(n+1)階層に属する操作項目である第1のショートカット用項目と、2階層分上位である第n階層に属する操作項目である第2のショートカット用項目を含める。第1、第2のショートカット用項目は、選択された操作項目に隣接していた操作項目である。これによって、操作メニューの階層が、2階層分深化した状態であっても、例えば、第n階層で選択を誤ったことが分かった時点で、直近の階層、さらにその上位の階層へと戻ることなく、所望の操作項目を選択でき、よって、冗長な操作が不要となり、利便性がさらに向上する。 In the sixth aspect, when the hierarchy is deepened by two hierarchies from the operation menu of the upper hierarchy (n hierarchy) (when it becomes the operation menu of the (n + 2) hierarchy), the operation menu of the (n + 2) hierarchy is The first shortcut item which is an operation item belonging to the (n + 1) hierarchy which is the nearest upper hierarchy and the second shortcut item which is an operation item belonging to the n-th hierarchy which is higher by two hierarchies are included. The first and second items for shortcut are operation items adjacent to the selected operation item. By this, even if the hierarchy of the operation menu is deepened by two hierarchies, for example, when it is found that the selection is wrong in the n-th hierarchy, returning to the nearest hierarchy and further higher hierarchy is performed. Instead, the user can select a desired operation item, thereby eliminating the need for redundant operations and further improving convenience.
 第1乃至第6の何れか1つの態様に従属する第7の態様において、
 前記操作メニュー画像生成部は、
 前記(n+1)階層の操作メニューの画像に含まれる前記ショートカット用項目の表示態様を、前記第(n+1)階層用の正規の複数の操作項目の表示態様とは異ならせる、
 又は、
 前記(n+1)階層の操作メニューの画像に含まれる前記ショートカット用項目に、前記第(n+1)階層用の正規の複数の操作項目とは種類が異なることを示す表示を追加するようにしてもよい。
In a seventh aspect dependent on any one of the first to sixth aspects,
The operation menu image generation unit
The display mode of the shortcut item included in the image of the operation menu of the (n + 1) layer is made different from the display mode of the plurality of normal operation items for the (n + 1) layer.
Or
A display may be added to the shortcut item included in the image of the operation menu of the (n + 1) layer, indicating that the type is different from the plurality of normal operation items for the (n + 1) layer. .
 第7の態様では、下位階層の操作メニューにおいて、ショートカット用項目を、正規の操作項目と区別し得るように、ショートカット用項目の表示態様を異ならせる(例えば、アイコンの色を変える、白黒を反転させて表示する、項目キーを点滅させる、項目キーの外枠を太線あるいは色を変えた線で描いて強調する等)、あるいは、種類が異なることを示す表示(記号、図形、文字等)を追加する。これによって、ユーザーは、下位階層の操作メニューに含まれるショートカット用項目の位置を、容易に(例えば、直観的に)把握でき、利便性がさらに向上する。 In the seventh aspect, in the lower-level operation menu, the display mode of the shortcut item is made different so that the shortcut item can be distinguished from the regular operation item (for example, the color of the icon is changed, black and white are reversed). Display items, blink item keys, draw outlines of item keys with bold lines or lines with different colors, etc.), or display (symbols, figures, characters, etc.) indicating that the type is different. to add. By this, the user can easily (eg, intuitively) grasp the position of the shortcut item included in the operation menu of the lower hierarchy, and the convenience is further improved.
 第1乃至第7の何れか1つの態様に従属する第8の態様において、
前記操作メニュー画像生成部が生成する前記操作メニューの画像は、原点を有し、前記原点から外側に向かう複数の放射状の直線によって、操作メニューの表示領域が区画されてなるラジアルメニューの画像であるようにしてもよい。
In an eighth aspect dependent on any one of the first to seventh aspects,
The image of the operation menu generated by the operation menu image generation unit is an image of a radial menu in which the display area of the operation menu is divided by a plurality of radial straight lines having an origin and extending outward from the origin. You may do so.
 第8の態様では、操作メニューの表示形式として、ラジアルメニュー形式を採用する。ラジアルメニューは、円を細分化する(例えば、扇形や楔(くさび)形の領域に分割する)ことで、多数の項目を、コンパクトにバランスよく配置することができる。項目が増えれば、選択ミスが生じる可能性が高まるが、万一、選択を誤っても、次の階層でショートカット用項目を用いて失敗から迅速に回復できることから、ユーザーの心理的な負担は増えない。よって、快適で実用的な車両用操作メニュー表示制御が実現される。 In the eighth aspect, a radial menu format is adopted as a display format of the operation menu. In the radial menu, a large number of items can be compactly arranged in a well-balanced manner by subdividing the circle (for example, dividing it into a fan-shaped or wedge-shaped area). If the number of items increases, the possibility of selection error increases, but even if the selection is wrong, the user's psychological burden increases because the user can quickly recover from the failure by using the shortcut item in the next layer. Absent. Therefore, comfortable and practical vehicle operation menu display control is realized.

 車載機器操作システムは、表示装置10と、入出力インターフェース(入出力I/F)20と、制御装置20(後述するが、表示制御装置(図2の符号21)と、処理実行装置(図2の符号26)と、を含んでいる)と、信号インターフェース(信号I/F)40、50と、ハンドル(ステアリングホイール)3に設けられ、ユーザー(ここでは運転者とする)が指(手)で操作可能な選択装置(入力装置)200と、ユーザーの視線を検出する視線検出部301及び音声検出部302(これらは、例えば、選択装置200を使用せずにメニューの項目を選択する場合に用いられる)と、制御装置20の外部機器(車載機器)400としての、各種のECU(車載ECU401、ナビ(ナビゲーション)ECU402、オーディオECU403、空調ECU404、外部通信部(通信機器)405を含み、これらはバスBUSを介して入出力I/F30に接続されている)と、を有する。 The in-vehicle device operation system includes a display device 10, an input / output interface (input / output I / F) 20, a control device 20 (described later, but a display control device (symbol 21 in FIG. 2), and a process execution device (FIG. 2). 26), the signal interface (signal I / F) 40, 50, and the steering wheel (steering wheel) 3, and the user (here, the driver) has a finger (hand) Selection device (input device) 200 that can be operated by the user, the gaze detection unit 301 that detects the gaze of the user, and the voice detection unit 302 (these are examples of selecting menu items without using the selection device 200, for example). Used as the external device (in-vehicle device) 400 of the control device 20, various ECUs (in-vehicle ECU 401, navigation (navigation) ECU 402, audio ECU 4 3, air-conditioning ECU404, wherein the external communication unit (communication devices) 405, which have a and that) is connected to the input-output I / F30 through the bus BUS.
 表示装置10は、実像及び虚像の画像の少なくとも一方を表示可能であり、ここでは、例えば、虚像を表示するHUD(ヘッドアップディスプレイ)装置を搭載するものとし、このHUD装置によって、ウインドシールド(フロントガラス等)2の虚像表示可能領域101(図中、破線の四角で示される)内に虚像を表示する。 The display device 10 can display at least one of a real image and a virtual image. Here, for example, it is assumed that a HUD (head-up display) device for displaying a virtual image is mounted. A virtual image is displayed in a virtual image displayable area 101 (shown by a dashed square in the figure) 2 of the glass etc.).
 図1では、虚像としてのラジアルメニュー(ラジアル操作メニュー)500(V)が表示されている。なお、符号500(V)の「(V)」は、虚像であることを示している。 In FIG. 1, a radial menu (radial operation menu) 500 (V) as a virtual image is displayed. In addition, "(V)" of code | symbol 500 (V) has shown that it is a virtual image.
 また、符号502は、ユーザーの指(手)の動き(選択装置200が検出する)に応じて位置が変化するポインタ(ここでは、時計の針のように、時計回りあるいは反時計回りに移動する)である。このポインタは、ラジアルメニュー(ラジアル操作メニュー)500(V)に含まれる複数の項目(操作項目)のうちの1つをポイント(指定)する機能をもつ。 Reference numeral 502 denotes a pointer whose position changes according to the movement of the user's finger (hand) (in this case, it moves clockwise or counterclockwise like a clock hand). ). The pointer has a function of pointing (specifying) one of a plurality of items (operation items) included in the radial menu (radial operation menu) 500 (V).
 なお、表示装置10は、インストルパネル内又はインストルパネル上に設けられる表示パネル等の表示器を含んで構成されてもよい。 The display device 10 may be configured to include a display such as a display panel provided in or on the instrument panel.

 次に、図2を参照する。図2(A)は、図1の車載機器操作システムにおける、制御装置及び車両用操作メニュー表示制御装置(表示制御装置)の、より具体的な構成例を示す図、図2(B)は、操作メニュー画像生成部の構成例を示す図、図2(C)は、表示装置の構成例を示す図である。図2において、図1と共通する部分には、同じ符号を付している(この点は、以降の図においても同様である)。 Next, FIG. 2 will be referred to. FIG. 2A is a diagram showing a more specific configuration example of the control device and the operation menu display control device for a vehicle (display control device) in the in-vehicle device operation system of FIG. 1, and FIG. FIG. 2C is a view showing a configuration example of an operation menu image generation unit, and FIG. 2C is a view showing a configuration example of a display device. In FIG. 2, the same reference numerals as in FIG. 1 denote the same parts as in FIG. 1 (this point is the same in the following figures).
 図2(A)において、制御装置20は、表示制御装置(車両用操作メニュー表示制御装置)21と、処理実行装置26と、を有し、必要に応じて、記憶装置(不図示)に、動作ルーチンファイル27が記憶される。 In FIG. 2A, the control device 20 has a display control device (vehicle operation menu display control device) 21 and a processing execution device 26, and, if necessary, a storage device (not shown), The operation routine file 27 is stored.
 表示制御装置(車両用操作メニュー表示制御装置)21は、操作メニュー画像生成部22と、操作メニュー表示処理部24と、を有しており、必要に応じて、記憶装置(不図示)内にメニューファイル25が記憶される。 The display control device (vehicle operation menu display control device) 21 has an operation menu image generation unit 22 and an operation menu display processing unit 24 and, if necessary, in a storage device (not shown). A menu file 25 is stored.
 上記の制御装置20の各構成は、例えば、記憶装置(不図示)に格納されているOS(オペレーティングシステム)等に搭載されるGUI(グラフィカルユーザーインターフェース)プログラムに従ってCPUやMPU(コンピュータ:不図示)が動作することで実現することができる。 Each configuration of the control device 20 described above is, for example, a CPU or MPU (computer: not shown) according to a GUI (Graphical User Interface) program installed in an OS (Operating System) etc. stored in a storage device (not shown) Can be realized by operating.
 表示制御装置(車両用操作メニュー表示制御装置)21における操作メニュー画像生成部22は、操作メニュー画像を生成する。例えば、予め用意されている複数のメニューファイル25の中から使用可能なものを取り出し(読み出し)、必要な情報を画像合成で組み込むことで、複数の操作項目を含むメニュー(操作メニュー)の画像を生成する。但し、これに限定されるものではなく、記憶部(不図示)に予め記憶された配列、又は記憶部(不図示)に記憶されたプログラムにより定められた配列に従って、複数の項目を配置する(項目を画像合成する)ことで、メニュー(操作メニュー)の画像を生成してもよく、あるいは、レンダリングにより画像を生成してもよい。生成された画像は、画像RAM(不図示)等に、一旦、蓄積される。 The operation menu image generation unit 22 in the display control device (vehicle operation menu display control device) 21 generates an operation menu image. For example, by taking out (read out) usable ones from a plurality of menu files 25 prepared in advance and incorporating necessary information in image synthesis, an image of a menu (operation menu) including a plurality of operation items is obtained. Generate However, the present invention is not limited to this, and a plurality of items are arranged according to an array stored in advance in a storage unit (not shown) or an array defined by a program stored in a storage unit (not shown) An image of a menu (operation menu) may be generated by image combining of items, or an image may be generated by rendering. The generated image is temporarily stored in an image RAM (not shown) or the like.
 なお、表示制御装置(車両用操作メニュー表示制御装置)21は、外部機器400(車載ECU401、ナビECU402、オーディオECU403、空調ECU404、外部通信部(通信機器)405)からの情報を使用して画像を生成することができ、あるいは、その情報を使用せずに、記憶部(不図示)に予め記憶された画像データのみに基づき画像を生成してもよい。これによって、例えば、図1で示したラジアルメニュー500(V)の元となる画像(元画像)を生成することができる。 The display control device (vehicle operation menu display control device) 21 is an image using information from the external device 400 (in-vehicle ECU 401, navigation ECU 402, audio ECU 403, air conditioning ECU 404, external communication unit (communication device) 405). Alternatively, without using the information, an image may be generated based only on image data stored in advance in a storage unit (not shown). Thereby, for example, an image (original image) which is the source of the radial menu 500 (V) shown in FIG. 1 can be generated.
 表示制御装置(車両用操作メニュー表示制御装置)21は、具体的には、階層構造を有すると共に、1つの階層の画像に複数の操作項目が含まれる操作メニューの表示を制御するものであり、上述のとおり、操作メニューの画像を生成する操作メニュー画像生成部22と、生成された操作メニューの画像の表示処理を行う操作メニュー表示処理部24と、を有し、操作メニュー画像生成部22は、選択装置200から出力される選択信号によって第n階層(nは1以上の自然数)の操作メニューに含まれる1つの操作項目が選択された結果として、選択された1つの操作項目に関連付けられた第(n+1)階層の操作メニューの画像を生成する場合に、第(n+1)階層用の正規の複数の操作項目と、n階層の操作メニューに含まれていた、選択された1つの操作項目以外の操作項目であるショートカット用項目(例えば、第n階層の操作メニューにおける選択された1つの操作項目に隣接して配置されていた、少なくとも1つの操作項目)と、を含む、第(n+1)階層の操作メニューの画像を生成するものである。 Specifically, the display control device (vehicle operation menu display control device) 21 has a hierarchical structure and controls the display of an operation menu in which a plurality of operation items are included in an image of one layer, As described above, the operation menu image generation unit 22 generates an image of the operation menu, and the operation menu display processing unit 24 performs display processing of the generated image of the operation menu, and the operation menu image generation unit 22 As a result of selection of one operation item included in the operation menu of the n-th layer (n is a natural number of one or more) by a selection signal output from selection device 200, it is associated with one operation item selected. When generating an image of the operation menu of the (n + 1) -th layer, the operation items included in the normal plurality of operation items for the (n + 1) -th layer and the operation menu of the n-th layer Items for shortcut which are operation items other than the selected one operation item (for example, at least one operation item arranged adjacent to the selected one operation item in the operation menu of the n-th hierarchy); To generate an image of the operation menu of the (n + 1) -th layer.
 また、生成する画像には、ショートカット用項目を選択する際の位置的基準を与える位置基準用項目としての、第n階層の操作メニューにおける選択された1つの操作項目を含ませることもできる。これらの点については、後述する。 In addition, the image to be generated may include one operation item selected in the operation menu of the n-th hierarchy as a position reference item for giving a positional reference when selecting the shortcut item. These points will be described later.
 図2(A)における操作メニュー表示処理部24は、画像RAM(不図示)等から、生成された画像(画像データ)を読み出し、データ形式を整えたり、表示に必要な情報を付加したりし、その結果として得られた画像データを表示装置10に送る。 The operation menu display processing unit 24 in FIG. 2A reads out the generated image (image data) from the image RAM (not shown) or the like, arranges the data format, and adds information necessary for display. The image data obtained as a result is sent to the display device 10.
 表示される車両用操作メニューは、階層構造を有しており、選択された1つの項目に関連付けされた下位階層のメニューがある場合は、その下位階層のメニューが順次、表示される。下位階層のない項目が選択されると、例えば、操作メニュー画像生成部22から処理実行装置26に、最終的に選択された項目の内容を示す情報が送られる。処理実行装置26は、例えば、動作ルーチンファイル27を参照して、実行すべき処理の具体的な内容を示すデータを取得し(但し、この動作は不要な場合もあり得る)、取得したデータを、入出力I/F30及びバスBUSを経由して、外部機器(車載機器)400に送る。これによって、ユーザーによって選択された項目に関連付けられている処理が実行される。 The displayed vehicle operation menu has a hierarchical structure, and when there is a lower hierarchy menu associated with one selected item, the lower hierarchy menus are sequentially displayed. When an item having no lower hierarchy is selected, for example, information indicating the content of the finally selected item is sent from the operation menu image generation unit 22 to the processing execution device 26. The process execution unit 26 refers to the operation routine file 27, for example, to acquire data indicating the specific content of the process to be executed (however, this operation may not be necessary), and the acquired data is , To the external device (in-vehicle device) 400 via the input / output I / F 30 and the bus BUS. This causes the process associated with the item selected by the user to be performed.
 図2(B)を参照する。操作メニュー画像生成部600は、ユーザーによって1つの項目が選択されると、その項目に関連付けされた下位階層メニューがあるか否かを判定する下位階層有無判定部600と、下位階層メニュー有りと判定された場合に、下位メニュー画像(この画像には、上位メニュー項目についてのショートカット用項目、言い換えれば、ショートカットアイコン等が含まれる)を生成する、下位メニュー画像生成部700と、を有する。 Reference is made to FIG. When one item is selected by the user, operation menu image generation unit 600 determines lower layer presence / absence determination unit 600 that determines whether there is a lower layer menu associated with the item, and determines that the lower layer menu is present. And a lower menu image generation unit 700 that generates a lower menu image (this image includes an item for a shortcut for an upper menu item, in other words, a shortcut icon, etc.).
 図2(C)を参照する。表示装置10は、虚像の画像を表示するHUD装置500、及び実像の画像を表示する表示器600の少なくとも一方を含むことができる。なお、HUD装置500は光源502を有しており、例えば、この光源502の光強度が、画像データに基づいて画素単位で変調されることで、スクリーン(不図示)上に画像が表示され、その画像の表示光が、投射光学系(不図示)を介して、図1のウインドシールド(光の一部を透過し、一部を反射する性質をもつ部材)1に投射することで、例えば、図1で示したラジアルメニュー500(V)が表示される。 Reference is made to FIG. The display device 10 can include at least one of a HUD device 500 that displays an image of a virtual image and a display 600 that displays an image of a real image. The HUD device 500 includes a light source 502. For example, the light intensity of the light source 502 is modulated in pixel units based on image data to display an image on a screen (not shown). The display light of the image is projected onto the windshield (a member having a property of transmitting a part of light and reflecting a part) 1 of FIG. 1 through a projection optical system (not shown), for example, The radial menu 500 (V) shown in FIG. 1 is displayed.
 次に、図3を参照する。図3(A)~図3(C)は、第1階層から、第2階層を経て第3階層に遷移する場合の操作項目メニューの第1の表示例を示す図、図3(D)~図3(F)は、第2の表示例を示す図である。 Next, FIG. 3 will be referred to. FIGS. 3A to 3C are diagrams showing a first display example of the operation item menu when transitioning from the first hierarchy to the third hierarchy via the second hierarchy; FIGS. FIG. 3F is a diagram showing a second display example.
 まず、図3(A)~図3(C)の例について説明する。図3(A)に示すように、最上位の階層である第1階層の操作メニューの画像は、所定の外形(ここでは、縦長の長方形)をもつメニュー全体の表示領域を、m個(mは2以上の自然数であり、図3(A)の例ではm=4)の操作項目(項目A~D)の表示用領域(縦長の長方形を4分割してなる長方形)で分割して構成されてなる操作メニューの画像である。 First, examples of FIG. 3A to FIG. 3C will be described. As shown in FIG. 3A, the image of the operation menu of the first hierarchy, which is the highest hierarchy, has m (m (m)) display areas of the entire menu having a predetermined outer shape (here, a vertically elongated rectangle). Is a natural number of 2 or more, and is divided into display areas (rectangles formed by dividing a vertically-long rectangle into four) of operation items (items A to D) of the example of FIG. It is an image of the operation menu that has been
 図3(A)では、項目Cが選択されるものとする。項目Cの表示用領域(斜線の領域)にはZN1という符号が付されている。なお、選択された項目Cの表示用領域ZN1に隣接する項目B、項目Dの各表示用領域には、砂模様を付してある。 In FIG. 3A, item C is selected. The display area (hatched area) of the item C is denoted by reference numeral ZN1. The display areas of the item B and the item D adjacent to the display area ZN1 of the selected item C are sanded.
 第1階層の操作メニューの画像に含まれる1つの操作項目(上記のとおり、ここでは項目Cである)が選択されると、その選択された1つの項目に関連付けされた第2階層の操作メニューが生成される。図3(B)は、その第2階層の操作メニューの画像の例を示している。 When one operation item (as described above, here, item C) included in the image of the operation menu of the first layer is selected, the operation menu of the second layer associated with the selected one item Is generated. FIG. 3B shows an example of the image of the operation menu of the second hierarchy.
 図3(B)において、項目V~Zが、下位階層メニュー(第2階層)における正規(本来)の項目であり、項目Cは、ショートカット用項目を選択する場合の基準位置となる(選択履歴を明確化する機能も併せ持つ)基準位置用項目であり、項目B、Dは、選択を誤った場合に、第1階層に戻らずにショートカットを可能とするためのショートカット用項目である。 In FIG. 3 (B), items V to Z are normal (intrinsic) items in the lower hierarchy menu (second hierarchy), and item C is a reference position when selecting a shortcut item (selection history (selection history) And the items B and D are items for a shortcut for enabling the shortcut without returning to the first layer when the selection is mistaken.
 図3(B)から明らかなように、第2階層の操作目メニューの画像においても、所定の外形(縦長の長方形)をもつメニュー全体の表示領域は維持されており、かつ、第1階層において選択された操作項目の表示用領域(図3(A)の領域ZN1)に相当する、同形状で同サイズの領域(図3(B)の領域ZN2)を、メニュー全体の表示領域に対する位置関係をそのまま維持しつつ(図3(A)の領域ZN1と、図3(B)の領域ZN2の上下方向における位置は同じである)設けている。 As is clear from FIG. 3B, the display area of the entire menu having a predetermined outer shape (long rectangle) is maintained even in the image of the operation eye menu of the second hierarchy, and in the first hierarchy, The same shape and size area (area ZN2 of FIG. 3B) corresponding to the display area of the selected operation item (area ZN1 of FIG. 3A) with respect to the display area of the entire menu (The positions of the region ZN1 in FIG. 3A and the position in the vertical direction of the region ZN2 in FIG. 3B are the same).
 そして、図3(B)の領域ZN2内を、3分割して3つの表示領域(上、中、下の各領域)を確保し、上の領域に、先に選択された項目Cを、ショートカット用項目を選択する場合の基準となる(選択履歴を明確化する機能も併せ持つ)基準位置用項目として、再度、配置(表示)する。 Then, the area ZN2 in FIG. 3B is divided into three to secure three display areas (upper, middle, lower areas), and the item C selected earlier is shortcut in the upper area. It arranges (displays) again as a reference position item which becomes a reference when selecting the item (also having a function of clarifying the selection history).
 そして、基準位置用項目としての項目Cに隣接するように、ショートカット用項目としての項目B、D(砂模様の領域)を再度、配置(表示)する。このとき、項目Bは、項目Cの上側(上方向)に配置し、項目Dは、項目Cの下側(下方向)に配置し、図3(A)と図3(B)との間で、項目の配置方向における相対的位置関係が維持される(保たれる)ようにする。 Then, the items B and D (sand area) as the shortcut items are arranged (displayed) again so as to be adjacent to the item C as the reference position item. At this time, the item B is placed on the upper side (upper direction) of the item C, and the item D is placed on the lower side (lower direction) of the item C, and between FIG. 3 (A) and FIG. 3 (B) So that the relative positional relationship in the arrangement direction of the items is maintained (maintained).
 言い換えれば、図3(A)における、項目Cに対する、項目B、項目Dの各々の配置方向における位置関係は、図3(B)における、項目C(位置基準用項目)に対する、項目B、D(ショートカット用項目)の各々の配置方向における位置関係と同じである。これによって、ユーザーが違和感を覚えることがない。 In other words, the positional relationship in the arrangement direction of each of the item B and the item D with respect to the item C in FIG. 3A corresponds to the item B, D with respect to the item C (item for position reference) in FIG. It is the same as the positional relationship in each arrangement direction of (item for shortcut). This does not make the user feel uncomfortable.
 具体的には、ショートカット用項目(図3(B)の例における項目B、Dについては、領域ZN2(領域ZN1と同形状で同サイズの領域)内において、基準位置用項目(図3(B)の例における項目C)に隣接して設けるという第1の規則(図3(B)では、項目Dがこの規則に従って配置されている)、又は、領域ZN2に隣接して設ける(図3(B)の例では、項目Bがこの規則に従って配置されている)、という第2の規則のうちの少なくとも一方が満足されるように設けるのが好ましい。 Specifically, for the item for shortcut (for items B and D in the example of FIG. 3B), the item for reference position (FIG. 3 (B The first rule (in FIG. 3 (B) that the item D is arranged according to this rule) to be provided adjacent to the item C) in the example of) or the region ZN2 is provided adjacently (FIG. In the example of B), it is preferable that at least one of the second rule that the item B is arranged in accordance with this rule be satisfied.
 ユーザーは、図3(A)に基づく表示を見ることで、項目B、C、Dの配置を記憶しており、また、選択した項目Cの表示領域に対する、項目B、項目Dの各表示領域の位置関係を記憶していると考えられる。よって、下位階層メニューを表示する際、上記のユーザーの記憶に、極力、反しないように、相対的位置関係を保ってショートカット用項目を配置することで、ユーザーが違和感を覚えることがないようにすることができる。 The user stores the arrangement of items B, C and D by looking at the display based on FIG. 3A, and displays each item of items B and D with respect to the display area of the selected item C. It is thought that the positional relationship of is stored. Therefore, when displaying the lower-level menu, the user can not feel a sense of incongruity by arranging the items for shortcut while keeping the relative positional relationship as much as possible in the user's memory. can do.
 図3(B)の例では、領域ZN2内の、下の領域に正規の下位項目である項目Vが配置されており、よって、ユーザーは、指(手)を大きく動かすことなく、ポインタを項目Vに移動させて、これを選択することができる。図3(B)において、項目Vは、破線の楕円で囲んで表記している。図3(B)では、正規の下位項目である項目Vが選択されるものとする。 In the example of FIG. 3 (B), the item V which is a regular lower item is arranged in the lower area in the area ZN2, and therefore, the user does not move the finger (hand) a lot, the pointer You can move it to V and select it. In FIG. 3 (B), the item V is indicated by being surrounded by a dashed oval. In FIG. 3B, it is assumed that the item V which is a regular lower item is selected.
 図3(C)において、項目α~μは、下位階層メニュー(第3階層)における正規(本来)の項目である。ここでは、領域ZN1(及びZN2)と同形状で同サイズの領域ZN3を設け、この中に、第2階層にて選択された項目Vを位置基準用項目として配置し、項目Vの上下に、ショートカット用項目としての項目B、W(第2階層にて、項目Vに隣接していた項目である)を、相対的位置関係を保って配置し、項目Bについては、領域ZN3に隣接して設けている。言い換えれば、第3階層においても、上記の第1、第2の規則の少なくとも1つが満たされるように配置されている。図3(C)では、例えば、項目λが選択される。この項目λに関連付けられた下位階層メニューが無い場合には、この項目λに関連付けられた内容の処理が実行される。 In FIG. 3C, items α to μ are normal (original) items in the lower layer menu (third layer). Here, an area ZN3 having the same shape and size as the area ZN1 (and ZN2) is provided, in which the item V selected in the second hierarchy is arranged as a position reference item, and above and below the item V, Items B and W as items for shortcut (which are items adjacent to item V in the second hierarchy) are arranged in a relative positional relationship, and item B is adjacent to area ZN3. It is provided. In other words, at least one of the first and second rules described above is also arranged in the third hierarchy. In FIG. 3C, for example, the item λ is selected. If there is no lower hierarchy menu associated with this item λ, processing of the content associated with this item λ is executed.
 次に、図3(D)~図3(F)を参照する。図3(D)は、図3(A)と同じである。
図3(E)では、領域ZN2内の中、下の各領域に、正規の下位項目である項目V、Wの2つを配置している(この点、図3(B)とは異なる)。正規の項目Wも領域ZN2内にあることから、ユーザーは、項目Wを選ぶ場合に、指(手)を大きく動かす必要がない。また、図3(E)では、ショートカット用項目Dは、領域ZN2の下側において、領域ZN2に隣接して設けている。この場合、上記の第2規則(領域ZN2に隣接して設けるという規則)は満足されているので、ユーザーは違和感を覚えない。
Next, FIG. 3D to FIG. 3F will be referred to. FIG. 3 (D) is the same as FIG. 3 (A).
In FIG. 3E, two items V and W, which are normal lower items, are arranged in the lower area in the area ZN2 (this point is different from FIG. 3B) . Since the regular item W is also in the area ZN2, the user does not have to move the finger (hand) largely when selecting the item W. Further, in FIG. 3E, the shortcut item D is provided adjacent to the area ZN2 below the area ZN2. In this case, the user does not feel discomfort because the second rule (the rule of providing the region ZN2 adjacent to the above) is satisfied.
 図3(F)では、第2階層にて選択された項目V(基準位置用項目)が、領域ZN3内の上の領域に配置されており、中、下の領域には各々、正規の下位項目W、第1階層へのショートカット用項目Dが配置される。第1階層へのショートカット用項目Bについては、第2階層と同様に、領域ZN3の上側に隣接して設けられており、第2階層の位置関係がそのまま維持されている。 In FIG. 3F, the item V (reference position item) selected in the second hierarchy is arranged in the upper area in the area ZN3, and in the middle and lower areas, respectively, lower than the normal lower An item W and an item D for shortcut to the first hierarchy are arranged. The item B for shortcut to the first hierarchy is provided adjacent to the upper side of the area ZN3 similarly to the second hierarchy, and the positional relationship of the second hierarchy is maintained as it is.
 このように、ユーザーにとって、最も目にする機会が多く、大きな印象を与えやすい第1階層における表示(表示項目、表示領域ZN1等)を考慮し、これを起点として、相対的な位置関係(配置方向の位置関係や隣接の位置関係)を、同じ(略同じを含む)に保ちながら上位階層へのショートカット用項目を、基準位置用項目と共に配置している。よって、ユーザーは、違和感を覚えることなく操作(選択操作)をすすめることができる。また、ショートカット用項目を過度に集中させずに、適切に分散させ、例えば、領域ZN1と同形状で同サイズの領域である領域ZN2やZN3内に、正規の下位項目(特に、優先順位が高いと推定されるもの)を配置している。したがって、選択が成功した場合には、ユーザーは、指(手)を大きく動かすことなく、優先順位が高い正規の項目(項目キー)を選択できるようになる。言い換えれば、選択に失敗した場合は、指(手)を大きく動かすことなく上位階層にショートカットが可能であり、かつ、選択が成功した場合における操作性が低下しないようにも配慮された項目(キー)配列となっている。 As described above, in consideration of the display (display item, display area ZN1, etc.) in the first hierarchy where the user has the most opportunity to see and is likely to give a large impression, relative positional relationship (arrangement) starting from this is considered The items for the shortcut to the upper hierarchy are arranged together with the items for the reference position while keeping the positional relationship of the directions and the positional relationship of the adjacent ones the same (including substantially the same). Therefore, the user can proceed with the operation (selection operation) without feeling discomfort. Further, the shortcut items are appropriately dispersed without excessively concentrating the items, and for example, regular sub-items (in particular, the priority is high in the areas ZN2 and ZN3 which are areas having the same shape and size as the area ZN1) Is supposed to be Therefore, if the selection is successful, the user can select a high priority regular item (item key) without moving the finger (hand) greatly. In other words, if the selection fails, a shortcut can be made in the upper hierarchy without moving the finger (hand) greatly, and the item (key taken into consideration so that operability in the case of successful selection is not degraded) ) Has become an array.
 図4は、表示制御処理(車両用操作メニュー表示制御処理)の主要な手順の一例を示すフローチャートである。 FIG. 4 is a flowchart showing an example of the main procedure of the display control process (the operation menu display control process for a vehicle).
 まず、最上位メニュー(最上位の操作メニュー)を表示し(ステップS1)、項目が選択されると(ステップS2)、選択された項目(操作項目)に対応する、次の下位階層のメニューを生成して表示する(ステップS3)。ここで、下位階層のメニューには、上位階層項目へのショートカットアイコン(ここでは、ショートカット用項目がアイコンとして表示されているものとする)が含まれる。 First, the top-level menu (top-level operation menu) is displayed (step S1), and when an item is selected (step S2), the next lower-level menu corresponding to the selected item (operation item) is displayed. It generates and displays (step S3). Here, the menu of the lower hierarchy includes a shortcut icon to the upper hierarchy item (here, the shortcut item is displayed as an icon).
 続いて項目が選択されると(ステップS4)、選択された項目がショートカットアイコンであるか否かを判定し(ステップS5)、Yの場合は、ショートカットアイコンが示す上位階層項目についての下位階層メニューを表示し(ステップS6)、ステップS4に戻る。 Subsequently, when an item is selected (step S4), it is determined whether the selected item is a shortcut icon (step S5). In the case of Y, a lower hierarchy menu for higher hierarchy items indicated by the shortcut icon Is displayed (step S6), and the process returns to step S4.
 ステップS5にて、Nの場合は、正規(本来)の下位メニュー項目であるかを判定し(ステップS7)、Yの場合は、関連付けられた次の下位項目があるかを判定し(ステップS9)、Yの場合は、選択された項目に対応する、次の下位階層のメニュー(過去に表示した各上位階層メニューの項目についてのショートカットアイコンを含む)を表示し(ステップS10)、Nの場合は、表示制御処理を終了する。車載機器操作システムが動作中であれば、表示制御処理は繰り返し実行される。表示制御処理は、終了後すぐに開始されてもよく、終了後に所定時間経過してから開始されてもよく、又はユーザーによる選択装置の操作が検出されたことで開始されてもよい。 In step S5, in the case of N, it is determined whether it is a normal (intrinsic) lower-level menu item (step S7), and in the case of Y, it is determined whether there is the next lower-order item associated (step S9). In the case of Y), the menu of the next lower hierarchy corresponding to the selected item (including the shortcut icon for the item of each upper hierarchy menu displayed in the past) is displayed (step S10), and in the case of N Ends the display control process. If the in-vehicle device operation system is in operation, the display control process is repeatedly executed. The display control process may be started immediately after the end, may be started after a predetermined time has elapsed after the end, or may be started when the operation of the selection device by the user is detected.
 ステップS7で、Nの場合は、選択された項目は、通常のリターンアイコン(直近の上位階層に戻るためのキー)であると考えられることから、直近の上位階層メニューを表示し(ステップS8)、ステップS4に戻る。 In step S7, in the case of N, since the selected item is considered to be a normal return icon (key for returning to the nearest upper hierarchy), the latest upper hierarchy menu is displayed (step S8) , And return to step S4.
 次に、図5を参照する。図5(A)は、選択装置(車載機器操作システムに用いられるポインティングデバイス)の外観を示す図、図5(B)は、図5(A)におけるA-A線に沿う断面構造を示す図である。 Next, FIG. 5 will be referred to. FIG. 5A is a view showing the appearance of a selection device (a pointing device used in a vehicle-mounted device operation system), and FIG. 5B is a view showing a cross-sectional structure along line AA in FIG. It is.
 ここでは、選択装置(入力装置、あるいは操作装置と称することもある)200が、図1において示したラジアルメニュー500における項目を選択することに用いられることを想定して説明する。 Here, it is assumed that the selection device (sometimes referred to as an input device or an operation device) 200 is used to select an item in the radial menu 500 shown in FIG.
 図5(A)に示されるように、選択装置(ポインティングデバイス)200は、ステアリングホイール3に配設され、ユーザーの指(ここでは、例えば親指とする)の位置(言い換えれば、操作位置C)を検出する操作位置検出部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が親指で押されることで、ユーザーによって選択(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. 5A, the selection device (pointing device) 200 is disposed on the steering wheel 3, and the position of the user's finger (here, for example, a thumb) (in other words, the operation position C) Operation position detection unit 210 for detecting the movement position detection unit 210 and the operation position detection unit 210, and the operation position detection unit 210 is pressed by the thumb to detect that the user has made a selection (decision). It has a determination operation detection unit 220 and a return switch 230 used when performing return processing.
 なお、上記の例では、選択装置200の操作を指(手)で行っているが、ユーザーの、その他の身体部位を用いてもよい。 In the above example, the operation of the selection device 200 is performed with a finger (hand), but another body part of the user may be used.
 選択装置200は、ユーザー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、図5(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。選択装置200は、ユーザーが、親指等でその操作面上を触れる操作(以下、タッチ操作という)あるいは所定の軌跡を描くようになぞる操作(以下、ジェスチャ操作という)を行った際に、ユーザーの親指等が操作面に触れている位置(操作位置C)を検出し、ユーザーによる選択(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(言い換えれば、選択(決定)検出信号)を出力する。 The selection device 200 is a touch sensor that detects the position (operation position C) at which the user's thumb or the like touches the operation surface, and as illustrated in FIG. 5B, the surface cover 211, the sensor sheet 212, and the spacer And 213. When the user performs an operation (hereinafter referred to as a touch operation) touching the operation surface with a thumb or the like (hereinafter referred to as a touch operation) or a tracing operation (hereinafter referred to as a gesture operation), the selection device 200 The position (operation position C) at which the thumb or the like touches the operation surface is detected, and when a selection (decision) is made by the user, the selection (decision) is detected, for example, the selection (decision) is made Is output (in other words, a selection (decision) detection signal).
 選択装置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5(A)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。また、図5(B)に記載されるように、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。ユーザーは、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、選択装置200を見なくても、選択装置200を操作することができる。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、ユーザーが、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、ユーザーは、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、ユーザーは、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。 The surface cover 211 in the selection device 200 is formed in a sheet shape by a light shielding insulating material such as a synthetic resin, and the three-dimensional shape of the convex cross section is continuously along the circumference of a circle centered on the central point Q. A relatively flat part (flat area) 211b connected to the formed convex part (convex area) 211a (an area having a radial pattern in FIG. 5A) and the convex part (convex area) 211a And. The convex portion (convex area) 211a has a mountain-shaped cross section (convex cross section), and the mountain (convex shape) is long in the direction (inward) toward the central point Q and short in the opposite direction, which is the outer side. It has an outline (edge line). The peaks (convex shape) are continuously provided along the circumference of a circle centered on the central point Q, whereby a convex portion (convex area) 211 a is configured. Further, as described in FIG. 5B, the sensor sheet 212 is provided under the convex portion (convex area) 211a in the surface cover 211, and the above-described operation position detection is performed by a portion including these. The unit 210 is configured. The user, for example, operates the operation position detection unit 210 by recognizing the slope in the longitudinal direction (the direction toward the center point Q, in other words, the inward direction) of the convex portion (convex area) 211a described above by the tactile sensation of a finger. The approximate position of the finger at the top can be recognized and the selection device 200 can be operated without looking at the selection device 200. In other words, blind operation is possible. In addition, although the case where the above-mentioned convex part (convex area) 211a is not provided may be assumed, also in this case, the user places the position of the hand (finger) along the circumference of a circle centered on the central point Q. When moved, the user can perceive the locus of the hand (finger) he / she moved (a trace of the temporal change of the position at which the finger or the like touches the operation surface of the touch sensor). You can get an idea of where you are on the circle's circumference. Therefore, even in this case, 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、ユーザーの指の操作位置Cを検出して、制御装置20(表示制御装置21)に、ユーザーの指等の操作位置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5(B)参照)。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、ユーザーの指等の移動が、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、例えば表示制御装置21が、ユーザーの指の位置を検出することが可能である。 The sensor sheet 212 is disposed along the circumference of a circle centered on the central point Q at least on the back surface side of the surface cover 211 corresponding to the convex portion (convex area) 211a, and the operation position C of the user's finger is It detects and outputs information (information on the operation position or a signal indicating the operation position) regarding the operation position C of the user's finger or the like to the control device 20 (display control device 21). The sensor sheet 212 is processed into the same shape as the surface cover 211, for example, by being integrally formed with the surface cover 211 by drawing (see FIG. 5B). By integrally molding in this manner, the surface cover 211 and the sensor sheet 212 become like a sheet, and the step shape of the above-mentioned convex part (convex area) 211 a is the bending of the sheet. It will be composed of parts (the raised parts). Further, by integrally molding in this manner, the back surface of the surface cover 211 abuts on the surface of the sensor sheet 212. Thus, the detection portion of the sensor sheet 212 is disposed corresponding to the step shape of the front cover 211. As described above, since the detection portion of the sensor sheet 212 is arranged corresponding to the step shape of the surface cover 211, the operation surface of the user's finger or the like has a step shape such as a convex portion (convex area) 211a. Even if performed above, for example, the display control device 21 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、ユーザーの指等によって、表面カバー211が表側から押圧された際に、上記の形状を保持する部材である。 The spacer 213 is located on the back surface side of the sensor sheet 212 and is formed in accordance with the shape of the integrally formed surface cover 211 and the sensor sheet 212, and when the surface cover 211 is pressed from the front side by the user's finger or the like. , It is a member holding the above-mentioned shape.
 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5(B)の例では5個)設けられる。決定操作検出部220は、制御装置20(表示制御装置21を含む)と電気的に接続されており、ユーザーが、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が押され、これによって、ユーザーによって選択(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(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(表示制御装置21を含む)に送られる。表示制御装置21は、送られてきた選択(決定)検出信号に基づき、例えば、ラジアルメニュー500に含まれる複数の項目のうちのどの項目が選択されたかを判定し、その選択に応じた操作メニュー画像を生成し、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 (five in the example of FIG. 5B) of the 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 (including the display control device 21), and the user operates the operation surface of the operation position detection unit 210 (convex portion (convex area) 211a of the surface cover 211). When an operation to press the key (hereinafter referred to as "press operation") is performed, the decision operation detection unit 220 is pressed, which detects that the user has made a selection (decision) and detects that the selection (decision) has been made. A signal (selection (decision) detection signal) to indicate is outputted, and the outputted selection (decision) detection signal is sent to the control device 20 (including the display control device 21.) The display control device 21 is sent. Based on the selected (decided) detection signal, for example, it is determined which of the plurality of items included in the radial menu 500 is selected, and an operation menu image corresponding to the selection is generated. Is displayed on the display device 10. Thus, in accordance with the contents of the selected item, the display is switched in the operation menu.
 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。ユーザーが、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内の表示制御装置21にリターン信号が送信される。表示制御装置21は、リターンスイッチ230からのリターン信号に基づき、ラジアルメニュー500の表示を、直近の過去の操作メニュー画像に戻す。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 located at a distance from the operation position detection unit 210 and the determination operation detection unit 220. When the user presses the operation surface of the return switch 230 (in other words, the pressing operation is performed), a return signal is transmitted to the display control device 21 in the control device 20. The display control device 21 returns the display of the radial menu 500 to the latest past operation menu image based on the return signal from the return switch 230. In other words, switching to the immediately preceding display is performed.
 次に、図6、図7を参照する。図6(A)は、ラジアル操作メニューにおける、第1階層(最上位階層)の操作メニュー例を示す図、図6(B)は、第2階層の操作メニュー例を示す図である。図7(A)は、ラジアル操作メニューにおける、第3階層の操作メニュー例を示す図、図7(B)は、第2階層の操作メニューの他の例を示す図である。 Next, FIG. 6 and FIG. 7 will be referred to. FIG. 6A is a diagram showing an example of an operation menu of the first hierarchy (upper hierarchy) in the radial operation menu, and FIG. 6B is a diagram showing an example of the operation menu of the second hierarchy. FIG. 7A is a view showing an example of the operation menu of the third layer in the radial operation menu, and FIG. 7B is a view showing another example of the operation menu of the second layer.
 図6、図7は、先に図3(D)~図3(F)を用いて説明した階層表示形式を、ラジアルメニュー(ラジアル操作メニュー)に適用した場合の具体例を示している。なお、ラジアルメニューとは、原点を有し、原点から外側に向かう複数の放射状の直線によって、メニューの表示領域が区画されてなるメニューであり、一般には、円(又は楕円)の外形を有する。 FIGS. 6 and 7 show specific examples in the case where the hierarchical display format described earlier with reference to FIGS. 3D to 3F is applied to a radial menu (radial operation menu). The radial menu is a menu having an origin and a display area of the menu divided by a plurality of radial straight lines extending outward from the origin, and generally has a circular (or elliptical) outer shape.
 ラジアルメニューは、例えば円を細分化する(例えば、扇形や楔(くさび)形の領域に分割する)ことで、多数の項目を、コンパクトにバランスよく配置することができる。なお、項目が増えれば、選択ミスが生じる可能性が高まるが、万一、選択を誤っても、先に説明したように、次の階層でショートカット用項目を用いて失敗から迅速に回復できることから、ユーザーの心理的な負担は増えない。よって、快適で実用的な、ラジアル形式の車両用操作メニューが実現される。 In the radial menu, a large number of items can be arranged in a compact and balanced manner, for example, by dividing a circle (for example, dividing it into a sector or wedge-shaped area). If the number of items increases, the possibility of selection error increases, but even if the selection is wrong, as described above, it is possible to quickly recover from the failure by using the shortcut item in the next layer. , The user's psychological burden does not increase. Thus, a comfortable and practical radial operation menu for a vehicle is realized.
 図6(A)は最上位階層(第1階層)の表示例である。外形の円が4分割されて得られる4つの扇形の領域(中心角90°)の各々に、1つ、あるいは複数の項目(操作項目)が割り当てられて配置されている。右下の扇形の領域(表示領域)ZN1には、AIR CONTROL(空調)という項目(但し、現在の車内温度が28度であるという情報も付加されている)1が配置されている。 FIG. 6A shows a display example of the top hierarchy (first hierarchy). One or a plurality of items (operation items) are allocated and arranged in each of four sector-shaped areas (central angle 90 °) obtained by dividing the circle of the outer shape into four. In the fan-shaped area (display area) ZN1 at the lower right, an item of AIR CONTROL (air conditioning) (provided that information that the current inside temperature is 28 degrees is also added) 1 is disposed.
 「AIR CONTROL(空調)」という項目1に隣接して(より正確には、時計回り方向に隣接して)、「SmartPhone(スマートフォン)」という項目2、「TEL(電話)」という項目2-1、「MAIL(メール)」という項目2-2が配置されている。 Adjacent to the item 1 "AIR CONTROL" (more precisely, adjacent in the clockwise direction), item 2 "SmartPhone", item 2-1 "TEL" , Item 2 "MAIL (mail)" is arranged.
 これらの項目に隣接して(より正確には、時計回り方向に隣接して)、「FUEL METER(燃料メータ)」という項目3が配置されている。 Adjacent to these items (more precisely, in the clockwise direction), an item 3 "FUEL METER (fuel meter)" is arranged.
 また、項目3に隣接して(より正確には、時計回り方向に隣接して)、「AUDIO(オーディオ)」という項目4が配置される。この項目4は、「AIR CONTROL(空調)」という項目1に隣接して(より正確には、反時計回り方向に隣接して)配置されていると見ることもできる。 Also, adjacent to the item 3 (more precisely, in the clockwise direction), an item 4 "AUDIO" is arranged. This item 4 can also be viewed as being disposed adjacent to the item 1 “AIR CONTROL” (more precisely, adjacent in the counterclockwise direction).
 ここでは、「AIR CONTROL(空調)」という項目1が選択されるものとする。図6(A)では、時計の針状のポインタ502は、この項目1を指している。 Here, it is assumed that the item 1 "AIR CONTROL (air conditioning)" is selected. In FIG. 6A, the needle pointer 502 of the clock points to this item 1.
 メニュー画像は、図6(B)のように切り替わる。図6(B)のメニューの外形は円であり、大きさも同じであり、図6(A)を踏襲しているので、ユーザーに違和感が生じない。 The menu image is switched as shown in FIG. 6 (B). The outer shape of the menu in FIG. 6B is a circle, the size is also the same, and since FIG. 6A is followed, the user does not feel uncomfortable.
 図6(B)では、「AIR CONTROL(空調)」に関係する、正規(本来)の下位項目(下位操作項目)1-2、1-3、1-4、1-6、1-7、1-8、1-9が表示される。 In FIG. 6 (B), normal (essentially) lower items (lower operation items) 1-2, 1-3, 1-4, 1-6, 1-7 related to “AIR CONTROL”. 1-8 and 1-9 are displayed.
 また、図6(A)で選択された項目である、「AIR CONTROL(空調)」という項目1が、図6(A)における右下の扇形(中心角90°)の領域ZN1と同じ形状で同じサイズの領域ZN2(ここでは、この領域が三分割されて、上、中、下の領域に区画されている)内において、具体的には、上の領域に、再度、配置されている。これが、先に説明した、ショートカット用項目を選択する際の位置的基準を与える位置基準用項目であり、この項目1は、現在、選択されている項目が「AIR CONTROL(空調)」であることを明確化する(言い換えれば、選択履歴を示す)機能も備えている。 Also, the item 1 “AIR CONTROL (air conditioning)”, which is the item selected in FIG. 6A, has the same shape as the area ZN1 in the lower right sector (center angle 90 °) in FIG. 6A. In the area ZN2 of the same size (here, this area is divided into three and divided into upper, middle and lower areas), specifically, it is arranged again in the upper area. This is the position reference item which gives the positional reference when selecting the shortcut item described above, and this item 1 is that the item currently selected is "AIR CONTROL". It also has the function of clarifying (in other words, showing the selection history).
 また、図6(B)における右下の扇形(中心角90°)の領域ZN2(図6(A)における項目1の表示領域ZN1と同じ形状で同じサイズの領域(三分割されて、上、中、下の領域に区画されている)内において、中、下の各領域には、「REAR(後部座席の空調)」という正規の項目1-2、「FRONT(前部座席の空調)」という正規の項目1-3が配置されている。これらの正規の項目1-2、1-3は、使用頻度が高いと推定されるものであり、これらが、図6(B)における右下の扇形(中心角90°)の領域内に配置されていることから、ポインタ502を少し動かすだけで選択が可能である。言い換えれば、図6(A)における選択が成功であった場合には、次の下位項目を、迅速に選択できる可能性が高められている。 6B (an area having the same shape and size as the display area ZN1 of item 1 in FIG. 6A (divided into three, upper, In the middle and lower areas), in the middle and lower areas, the regular item "REAR (air conditioning of the rear seat)", "FRONT (air conditioning of the front seat)" The regular items 1 to 3 are arranged, and these regular items 1 to 2 and 1 to 3 are estimated to be frequently used, and these are the lower right in FIG. Since it is arranged within the fan-shaped (center angle 90 °) area, the selection can be made by moving the pointer 502 a little. In other words, if the selection in FIG. , The possibility of quickly selecting the next sub-item has been increased .
 また、図6(B)において、「SmartPhone(スマートフォン)」という項目2、「AUDIO(オーディオ)」という項目4が、先に説明したショートカット用項目として配置されている。 Further, in FIG. 6B, an item 2 "SmartPhone" and an item 4 "AUDIO" are arranged as the shortcut items described above.
 「配置方向における相対位置関係」については、図6(B)において、項目4(ショートカット用項目)は、項目1(基準位置用項目)に対して、反時計回り方向における上側にあり、項目2(ショートカット用項目)は、項目1(基準位置用項目)に対して、時計回り方向における下側にある。これは、図6(A)における、項目4、項目2の、項目1に対する、配置方向における相対的位置関係と同じである。よって、ユーザーに、違和感を生じさせない。 As for "relative positional relationship in the arrangement direction", in FIG. 6B, item 4 (shortcut item) is on the upper side in the counterclockwise direction with respect to item 1 (reference position item), and item 2 The (shortcut item) is located below the item 1 (reference position item) in the clockwise direction. This is the same as the relative positional relationship in the arrangement direction with respect to item 1 in item 4 in item (A) of FIG. Thus, the user does not feel uncomfortable.
 また、「隣接」についての相対的位置関係については、先に、ショートカット用項目の配置に関して、基準位置用項目に隣接させてもよく(規則1)、上位階層において選択された項目の表示領域(図6(A)のZN1)と同じ形状で同じサイズの領域(図6(B)のZN2)に隣接させてもよい(規則2)の、少なくとも一方が満足されればよい、という点を記載したが、図6(B)において、ショートカット用項目である項目4については、規則1、2を共に満たし、ショートカット用項目である項目2については、規則2を満たしている。 In addition, with regard to the relative positional relationship of “adjacent”, the arrangement of the shortcut item may be adjacent to the reference position item (Rule 1), and the display area of the item selected in the upper hierarchy (Rule 1) The point that at least one of (Rule 2) may be satisfied, which may be adjacent to a region (ZN2 of FIG. 6B) having the same shape and size as that of ZN1 of FIG. 6A. However, in FIG. 6B, both the rules 1 and 2 are satisfied for the item 4 which is a shortcut item, and the rule 2 is satisfied for the item 2 which is a shortcut item.
 図6(A)、(B)を見比べると、相対的位置関係は略同じであり、よって、ユーザーに違和感を生じさせない。 When comparing FIGS. 6A and 6B, the relative positional relationship is substantially the same, and therefore, the user does not feel uncomfortable.
 図6(B)では、「REAR(後部座席の空調)」という正規の項目1-2が選択されるものとする。メニュー画像は、図7(A)のように切り替わる。 In FIG. 6B, it is assumed that the regular item 1-2 “REAR (air conditioning of rear seat)” is selected. The menu image is switched as shown in FIG. 7 (A).
 図7(A)では、後部座席の空調温度を設定する項目(REAR27.5℃、26℃、29℃、28.5℃の各アイコン)や、NEXTという項目(アイコン)、リターン記号の項目(リターンアイコン)が表示される。図6(A)の領域ZN1に対応する領域ZN3内には、基準位置用項目としての「REAR CONTROL(後部座席の空調)」という項目1-2が配置され、この第2階層へのショートカット用項目(ショートカットアイコン)1-3が、時計回りの方向に隣接して配置され、その隣に、第1階層へのショートカット用項目(ショートカットアイコン)2が配置され、また、第1階層へのショートカット用項目(ショートカットアイコン)4は、基準位置用項目としての「REAR CONTROL(後部座席の空調)」という項目1-2の、時計回り方向に隣接して設けられている。 In FIG. 7A, items for setting the air conditioning temperature of the rear seat (REAR 27.5 ° C., 26 ° C., 29 ° C., 28.5 ° C. icons), an item called NEXT (icon), and an item (return symbol) The return icon is displayed. In the area ZN3 corresponding to the area ZN1 in FIG. 6A, an item 1-2 “REAR CONTROL (air conditioning of the rear seat)” is arranged as an item for the reference position, and for the shortcut to the second hierarchy Items (shortcut icons) 1-3 are arranged adjacent to each other in the clockwise direction, and an item (shortcut icon) 2 for a shortcut to the first hierarchy is arranged next thereto, and a shortcut to the first hierarchy is also provided. The item (shortcut icon) 4 is provided in the clockwise direction adjacent to the item 1-2 of "REAR CONTROL (air conditioning of the rear seat)" as the item for the reference position.
 概ね、先に記載した規則1、規則2に従った配置が採用されている。図6(A)と図7(A)を見比べた場合、及び、図6(B)と図7(A)を見比べた場合、ショートカットアイコンの配置について、上位階層の配置が踏襲されて図7(A)のメニューが構成されていることから、ユーザーには、違和感を与える可能性が少ない。 In general, the arrangement according to rule 1 and rule 2 described above is adopted. When FIG. 6 (A) and FIG. 7 (A) are compared and FIG. 6 (B) and FIG. 7 (A) are compared, the arrangement of the upper hierarchy is followed for the arrangement of the shortcut icons. Since the menu of (A) is configured, the user is less likely to feel discomfort.
 次に、図7(B)を参照する。図7(B)では、下位階層の操作メニューにおいて、ショートカット用項目を、正規の操作項目と区別し得るようにしている。図7(B)の項目の配置は、図6(B)と同じであるが、図7(B)では、ショートカット用項目である項目2、4に、上位階層に戻るのと同じ効果を有する項目であることを暗示する矢印の記号を付加している。言い換えれば、図7(B)の例では、ショートカット用項目のアイコンに、種類が異なることを示す表示(記号、図形、文字等)を追加するという表示手法が採用されている。 Next, FIG. 7B will be referred to. In FIG. 7B, in the operation menu of the lower hierarchy, items for shortcut can be distinguished from regular operation items. The arrangement of the items in FIG. 7B is the same as that in FIG. 6B, but in FIG. 7B, the items 2 and 4 as shortcut items have the same effect as returning to the upper hierarchy. The symbol of the arrow which implies that it is an item is added. In other words, in the example of FIG. 7B, a display method is adopted in which a display (a symbol, a figure, a character, or the like) indicating that the type is different is added to the icon of the item for shortcut.
 但し、これに限定されるものではなく、ショートカット用項目の表示態様を異ならせる(例えば、アイコンの色を変える、白黒を反転させて表示する、項目キーを点滅させる、項目キーの外枠を太線あるいは色を変えた線で描いて強調する等)という表示手法を採用してもよい。 However, the present invention is not limited to this, and the display mode of the shortcut item is changed (for example, the color of the icon is changed, the black and white is inverted and displayed, the item key is blinked, the outline of the item key is thick Alternatively, a display method may be adopted in which lines are drawn with different colors and emphasized.
 このように、本発明によれば、ユーザー(車両1の運転者等)が、階層構造を有する操作メニューの操作項目を誤って選択した場合でも、階層を戻すという冗長な操作をすることなく、正しい操作項目を効率的に選択できるようになり、メニュー選択の利便性が格段に向上する。 As described above, according to the present invention, even when the user (the driver of the vehicle 1 or the like) erroneously selects the operation item of the operation menu having the hierarchical structure, the user does not perform the redundant operation of returning the hierarchy. It becomes possible to efficiently select the correct operation item, and the convenience of menu selection is greatly improved.
 なお、本明細書において、車両とは、例えば自動車、電車、飛行機、船舶等の「乗り物」を示す用語として広義に解釈し、又、メニューという用語も、例えば「複数の選択肢を含む表示」というように、広義に解釈するものとする。 In the present specification, a vehicle is broadly interpreted as a term indicating "vehicle" such as a car, a train, an airplane, a ship or the like, and the term "menu" is also referred to as "a display including a plurality of options". As such, it shall be interpreted in a broad sense.
 本発明は、上述の例示的な実施形態に限定されず、また、当業者は、上述の例示的な実施形態を特許請求の範囲に含まれる範囲まで、容易に変更することができるであろう。 The invention is not limited to the above-described exemplary embodiments, and one of ordinary skill in the art could easily modify the above-described exemplary embodiments to the extent that they are included in the claims. .
