≪ユーザ入力装置１≫
　図１は、ユーザ入力装置（一対の入力装置）を足に装着したユーザの外観図であり、図２は、足に装着された入力装置の本体部と装着部とを示す外観図であり、図３は、表示画面に表示されたカーソルの一例を示す図である。
　ユーザ入力装置１は、一対の入力装置１１と入力装置１２とからなる。図１及び図２に示すように、本実施形態では、入力装置１１が右足首に装着され、入力装置１２が左足首に装着されている。 << user input device 1 >>
FIG. 1 is an external view of a user wearing a user input device (a pair of input devices) on a foot, and FIG. 2 is an external view showing a main body and a mounting portion of the input device on the foot FIG. 3 is a view showing an example of the cursor displayed on the display screen.
The user input device 1 comprises a pair of input devices 11 and an input device 12. As shown in FIGS. 1 and 2, in the present embodiment, the input device 11 is attached to the right ankle, and the input device 12 is attached to the left ankle.
　コンピュータ５は、表示画面５１（図３）を備え、入力装置１１，１２とネットワーク６を介して、通信可能に接続されている。ユーザ入力装置１（入力装置１１，１２）は、表示画面５１（図３）に表示されたカーソル５２（マウスポインタ）の動作を制御する情報を送信するものである。 The computer 5 includes a display screen 51 (FIG. 3), and is communicably connected to the input devices 11 and 12 via the network 6. The user input device 1 (input devices 11 and 12) transmits information for controlling the operation of the cursor 52 (mouse pointer) displayed on the display screen 51 (FIG. 3).
　ここで、本実施形態では、ネットワーク６に無線ネットワークを用いているとして説明する。このネットワーク６は、例えば、無線ＬＡＮ（Local Area Network）やZigBee（登録商標）、Bluetooth（登録商標）等である。また、ネットワーク６は、例えば、ＵＳＢ（Universal Serial Bus）ケーブル等の有線ネットワークであってもよい。 Here, in the present embodiment, it is assumed that a wireless network is used as the network 6. The network 6 is, for example, a wireless local area network (LAN), ZigBee (registered trademark), Bluetooth (registered trademark) or the like. The network 6 may be, for example, a wired network such as a USB (Universal Serial Bus) cable.
　図１は、例えばカフェにおいてユーザ４がテーブルの上のコンピュータ５を使って入力作業をしている場合を示している。ユーザ４の足には本発明に係るユーザ入力装置１が装着されている。ユーザ４は、ユーザ入力装置１を足で操作することで、図３に示すようなコンピュータ５が備える表示画面５１に表示されたカーソル５２に係る動作をコンピュータ５に制御させることができる。 FIG. 1 shows, for example, a case where a user 4 is performing input work using a computer 5 on a table in a cafe. The user input device 1 according to the present invention is attached to the foot of the user 4. By operating the user input device 1 with the foot, the user 4 can cause the computer 5 to control the operation related to the cursor 52 displayed on the display screen 51 provided in the computer 5 as shown in FIG. 3.
　例えば、ユーザ４は、ユーザ入力装置１を足で操作することで、アイコン５３の位置までカーソル５２を移動させて、アイコン５３をクリック（選択）することができる。また、コンピュータ５にて文書作成ソフトが実行され、表示画面５１に表示された文章を範囲選択する場合に、ユーザ４は、ユーザ入力装置１を足で操作して、クリックを維持（選択維持）する動作をさせることで、範囲の始点から終点までの文章をドラッグして選択することができる。 For example, by operating the user input device 1 with the foot, the user 4 can move the cursor 52 to the position of the icon 53 and click (select) the icon 53. Further, when the document creation software is executed by the computer 5 and the range selection of the text displayed on the display screen 51 is performed, the user 4 operates the user input device 1 with his foot and maintains the click (selection maintenance) By performing the action, the text from the start point to the end point of the range can be selected by dragging.
（入力装置１１，１２）
　入力装置１１，１２は、図２に示すように、それぞれ本体部２と装着部３とを備える。
　本体部２は、内部に動作指示部２１、検出部２２、通信部２３等を備えるものであり、詳細は後記する。図２では本体部２を箱形の形状で示したが、どのような形状であっても構わない。 (Input devices 11, 12)
As shown in FIG. 2, the input devices 11 and 12 each include a main body portion 2 and a mounting portion 3.
The main body unit 2 internally includes an operation instructing unit 21, a detection unit 22, a communication unit 23, and the like, and the details will be described later. Although the main body 2 is shown in a box shape in FIG. 2, it may have any shape.
　装着部３は、本体部２をユーザ４の足に装着するものである。例えば、足に巻き付けて装着するバンド等の有端状ベルトであってもよいし、足を通して装着するゴムや輪等の無端状ベルトであってもよい。この装着部３は、足が傾いたことを検出できるように、本体部２が足の軸に固定されるものであればよい。
　また、装着位置は、足首に限定されるものではないが、足首から膝までの間であることが望ましい。 The mounting unit 3 is for mounting the main unit 2 on the foot of the user 4. For example, it may be an end-like belt such as a band which is wound around and attached to a foot, or an endless belt such as rubber or a wheel which is attached through a foot. The mounting portion 3 may be any one as long as the main body portion 2 is fixed to the axis of the foot so as to detect that the foot is inclined.
Also, the wearing position is not limited to the ankle, but is preferably between the ankle and the knee.
　ここで、装着部３により足に装着された本体部２（特に図４に示す検出部２２）が鉛直線上にありかつ水平面上にある場合を、本体部２（検出部２２）が「基準軸に位置する」状態とする。すなわち、本体部２（検出部２２）が「基準軸に位置する」状態とは、基準軸の傾きがなく安定した状態に位置するときである。
　本実施形態において、入力装置１１（１２）の本体部２がこの基準軸に位置する場合、入力装置１１（１２）はカーソル５２に係る動作を制御する情報を送信しない。すなわち、表示画面５１にてカーソル５２が動作しない状態であるとする。 Here, when the main body 2 (particularly the detection unit 22 shown in FIG. 4) mounted on the foot by the mounting unit 3 is on a vertical line and on a horizontal plane, the main body 2 (detection unit 22) To be located in That is, the state in which the main body 2 (detection unit 22) is "located at the reference axis" is when the reference axis is not inclined and is positioned in a stable state.
In the present embodiment, when the main unit 2 of the input device 11 (12) is positioned on this reference axis, the input device 11 (12) does not transmit information for controlling the operation of the cursor 52. That is, it is assumed that the cursor 52 does not operate on the display screen 51.
　このとき、本体部２と装着部３とを接続する部材に、ねじ等による傾き調整部３２を備え、本体部２の傾きを手動で調整できるようにしてもよい。これにより、例えば、図８に示すように、ユーザ４が楽な姿勢で座った状態、すなわちストレスのかかりにくい状態における足の傾きを基準軸とすることできる。つまり、カーソル５２が勝手に動かないように（本体部２の内部にある検出部２２が鉛直線上にありかつ水平面上にあるように）、ユーザ４は傾き調整部３２を使って本体部２の傾き（基準軸）を手動で調整することができる。図８に示したように、ユーザ４が傾き調整部３２を使って左に傾けることで、足の軸（ａ）と基準軸（ｂ）とは必ずしも一致しない。このように、傾き調整部３２で本体部２の傾きを調整することで、個人個人に対応可能なストレスフリーのユーザ入力装置１を提供することができる。 At this time, the member for connecting the main body 2 and the mounting portion 3 may be provided with a tilt adjusting unit 32 such as a screw so that the tilt of the main body 2 can be manually adjusted. As a result, for example, as shown in FIG. 8, it is possible to use the inclination of the foot in a state in which the user 4 is seated in a comfortable posture, that is, a state in which stress is not easily applied. That is, the user 4 uses the tilt adjustment unit 32 to prevent the cursor 52 from moving freely (as the detection unit 22 inside the main unit 2 is on the vertical line and on the horizontal surface). The tilt (reference axis) can be adjusted manually. As shown in FIG. 8, when the user 4 tilts to the left using the tilt adjustment unit 32, the foot axis (a) and the reference axis (b) do not necessarily coincide with each other. As described above, by adjusting the inclination of the main body 2 by the inclination adjustment unit 32, it is possible to provide the stress-free user input device 1 compatible with an individual.
≪本体部２≫
　図４は、入力装置の本体部の内部構成を示す図である。
　本体部２は、動作指示部２１と、検出部２２と、通信部２３とを備える。動作指示部２１と検出部２２と通信部２３とは、不図示の電池等の電源部から電力が供給されることで動作する。
　本実施形態では、動作指示部２１は、制御部２１１と記憶部２１２とを備えるマイクロコントローラ（microcontroller）により実現される。この動作指示部２１については詳細を後記する。 «Main part 2»
FIG. 4 is a diagram showing an internal configuration of the main body of the input device.
The main unit 2 includes an operation instruction unit 21, a detection unit 22, and a communication unit 23. The operation instructing unit 21, the detection unit 22, and the communication unit 23 operate by supplying power from a power supply unit such as a battery (not shown).
In the present embodiment, the operation instruction unit 21 is realized by a microcontroller including the control unit 211 and the storage unit 212. The details of the operation instruction unit 21 will be described later.
（検出部２２）
　検出部２２は、本体部２の動きを検出するモーションセンサであり、検出内容を動作指示部２１に出力する構成部である。つまり、足が動き、本体部２がぶれる、すなわち基準軸が傾くことで、検出部２２がその傾き（本体部２の動き）を検出内容として出力する。この検出部２２は、加速度センサ２２１とジャイロセンサ２２２とを備える。 (Detector 22)
The detection unit 22 is a motion sensor that detects the movement of the main unit 2, and is a component that outputs the detection content to the operation instruction unit 21. That is, when the foot moves and the main body 2 is shaken, that is, the reference axis is inclined, the detection unit 22 outputs the inclination (the movement of the main body 2) as the detection content. The detection unit 22 includes an acceleration sensor 221 and a gyro sensor 222.
　加速度センサ２２１は、物体の加速度を計測する機器であり、この加速度センサ２２１により、物体の傾きを計測することができる。本実施形態では、加速度センサ２２１として３軸加速度センサを用いて、水平面上におけるＸ軸方向（図２における左右方向）の動きと、Ｙ軸方向（図２における前後方向）の動きと、鉛直線上におけるＺ軸方向（図２における上下方向）の動きとを計測する。そして、加速度センサ２２１は、この計測した値（検出値）を検出内容として出力する。 The acceleration sensor 221 is a device that measures the acceleration of the object, and the acceleration sensor 221 can measure the tilt of the object. In this embodiment, a 3-axis acceleration sensor is used as the acceleration sensor 221, and movement in the X-axis direction (horizontal direction in FIG. 2), movement in the Y-axis direction (front-rear direction in FIG. The movement in the Z-axis direction (vertical direction in FIG. 2) in Then, the acceleration sensor 221 outputs the measured value (detection value) as the detection content.
　ジャイロセンサ２２２は、物体の角度や角速度を計測する機器であり、このジャイロセンサ２２２により、物体が動いた直後の瞬間的な傾きを計測することができる。本実施形態では、ジャイロセンサ２２２として圧電振動ジャイロモジュールを用いて、水平面上におけるＸ軸方向（図２における左右方向）の傾きと、Ｙ軸方向（図２における前後方向）の傾きとを計測する。そして、ジャイロセンサ２２２は、この計測した値（検出値）を検出内容として出力する。 The gyro sensor 222 is a device that measures the angle and angular velocity of the object, and the gyro sensor 222 can measure an instantaneous inclination immediately after the object moves. In this embodiment, using a piezoelectric vibration gyro module as the gyro sensor 222, the inclination in the X axis direction (horizontal direction in FIG. 2) and the inclination in the Y axis direction (longitudinal direction in FIG. 2) in the horizontal plane are measured. . Then, the gyro sensor 222 outputs the measured value (detection value) as the detection content.
（通信部２３）
　通信部２３は、ネットワーク６を介して、外部のコンピュータ５（図１）と通信する構成部である。この通信部２３は、動作指示部２１が決定した動作指示の情報を、ネットワーク６を介して送信できるようにデータ化して、コンピュータ５に送信する。 (Communication unit 23)
The communication unit 23 is a component that communicates with an external computer 5 (FIG. 1) via the network 6. The communication unit 23 converts the information of the operation instruction determined by the operation instruction unit 21 into data so that it can be transmitted via the network 6 and transmits the data to the computer 5.
（動作指示部２１）
　動作指示部２１は、制御部２１１と記憶部２１２とを備え、検出部２２が検出した値に基づく動作指示を決定する構成部である。 (Operation instruction unit 21)
The operation instruction unit 21 includes a control unit 211 and a storage unit 212, and determines an operation instruction based on the value detected by the detection unit 22.
　制御部２１１は、カーソル５２に係る動作を制御する情報を生成する構成部であり、例えば、ＣＰＵ（Central Processing Unit）である。制御部２１１が記憶部２１２に格納されるプログラムを展開し、実行することによって、動作指示部２１の機能が実現される。
　制御部２１１は、加速度センサ２２１と、ジャイロセンサ２２２とに接続され、それぞれから検出値（検出内容）を取得し、その検出値に基づく動作指示を決定し、動作指示の情報を生成する。 The control unit 211 is a configuration unit that generates information for controlling an operation related to the cursor 52, and is, for example, a CPU (Central Processing Unit). The control unit 211 develops the program stored in the storage unit 212 and executes the program, whereby the function of the operation instructing unit 21 is realized.
The control unit 211 is connected to the acceleration sensor 221 and the gyro sensor 222, acquires a detection value (detection content) from each of them, determines an operation instruction based on the detection value, and generates information of the operation instruction.
　記憶部２１２は、データやプログラムを記憶する構成部であり、例えば、ＲＡＭ（Random Access Memory）やＲＯＭ（Read Only Memory）等である。 The storage unit 212 is a configuration unit that stores data and programs, and is, for example, a random access memory (RAM) or a read only memory (ROM).
　ここで、本体部２の動きと、検出部２２（加速度センサ２２１及びジャイロセンサ２２２）が計測した値（検出値）の変化と、その検出値に基づき制御部２１１が決定する動作指示の一例について表１を用いて説明する。ここでは、制御部２１１が決定する動作指示と、一般的なマウス操作とを関連づけて説明する。 Here, an example of an operation instruction determined by the control unit 211 based on the movement of the main unit 2, the change of the value (detection value) measured by the detection unit 22 (the acceleration sensor 221 and the gyro sensor 222), and the detection value This will be described using Table 1. Here, the operation instruction determined by the control unit 211 will be described in association with a general mouse operation.
　以下の表１に示す足の動きをすることで、加速度センサ２２１及びジャイロセンサ２２２が計測した値（検出値）が変化する。制御部２１１は、これら加速度センサ２２１及びジャイロセンサ２２２から検出値を随時取得し、この変化後の検出値を判定して、動作指示を決定する。この判定の条件は、例えば、変化後の検出値が所定の閾値を超えたか否かである。 By moving the feet shown in Table 1 below, the values (detection values) measured by the acceleration sensor 221 and the gyro sensor 222 change. The control unit 211 acquires detection values from the acceleration sensor 221 and the gyro sensor 222 as needed, determines the detection value after the change, and determines an operation instruction. The condition of this determination is, for example, whether or not the detected value after change exceeds a predetermined threshold.

（カーソル移動）
　ここで、図５を用いて、表１（１）に示す、右足を右に傾けた場合（カーソル右移動）について説明する。
　例えば、基準軸（ｂ）における加速度センサ２２１からのＸ軸の電圧値（検出値）は２．４[Ｖ]である。ここで、右足が右に傾けられ（Ｌ３～Ｌ４）、右足に装着された入力装置１１の制御部２１１が、加速度センサ２２１からＸ軸の電圧値（検出値）＝２．２[Ｖ]を取得したとき、図５にて本体部２として示す入力装置１１の制御部２１１は「カーソル 右移動」の動作指示を決定する。このとき、制御部２１１は、０．２[Ｖ]の変化量に応じて、カーソル５２の移動速度を決定し、その移動速度を動作指示に含める。 (Cursor movement)
Here, the case where the right foot is tilted to the right (cursor right movement) shown in Table 1 (1) will be described with reference to FIG.
For example, the voltage value (detected value) of the X axis from the acceleration sensor 221 in the reference axis (b) is 2.4 [V]. Here, the right foot is inclined to the right (L3 to L4), and the control unit 211 of the input device 11 attached to the right foot detects the voltage value (detection value) of the X axis = 2.2 [V] from the acceleration sensor 221. When acquired, the control unit 211 of the input device 11 shown as the main unit 2 in FIG. 5 determines an operation instruction of “cursor right movement”. At this time, the control unit 211 determines the moving speed of the cursor 52 according to the change amount of 0.2 [V], and includes the moving speed in the operation instruction.
　また、図５に示すように、基準軸（ｂ）から所定の範囲内（Ｌ２～Ｌ３）の足の傾きで得られる検出値の場合、制御部１１はカーソル移動の動作指示をしない。このとき、制御部１１は、加速度センサ２２１から取得した検出値が所定の範囲内である場合に、カーソル５２を移動させる動作指示をしない。このようにすることで、ユーザ４の足癖等による微妙な足の傾きで勝手にカーソル５２が移動することを回避することができる。 Further, as shown in FIG. 5, in the case of the detection value obtained by the inclination of the foot within a predetermined range (L2 to L3) from the reference axis (b), the control unit 11 does not give an operation instruction of cursor movement. At this time, when the detection value acquired from the acceleration sensor 221 is within the predetermined range, the control unit 11 does not instruct the operation to move the cursor 52. By doing this, it is possible to prevent the cursor 52 from moving by hand due to a slight foot inclination due to a toe or the like of the user 4.
（選択）
　ここで、図６を用いて、表１（６）に示す、左足の踵を上げた場合（左クリック）について説明する。
　左足のつま先を動かさずに踵を上げることで、本体部２が上方向へ瞬間的に上がることになる。これにより、制御部２１１が取得する、加速度センサ２２１のＺ軸方向の検出値と、ジャイロセンサ２２２のＸ軸方向の検出値及びＹ軸方向の検出値とが共に、クリックされたと判定する閾値を超えた場合、制御部２１１は「左クリックする」の動作指示を決定する。このとき、ジャイロセンサ２２２により検出される値は、瞬間的な上方向への動きにより本体部２が動くためである。 (Choice)
Here, the case where the heel of the left foot is raised (left click) shown in Table 1 (6) will be described using FIG.
By raising the heel without moving the toes of the left foot, the main body part 2 will rise momentarily upward. Thereby, the threshold value determined by the control unit 211 that the detected value in the Z-axis direction of the acceleration sensor 221 and the detected value in the X-axis direction and the detected value in the Y-axis direction of the gyro sensor 222 are both clicked When it exceeds, the control unit 211 determines an operation instruction of “left click”. At this time, the value detected by the gyro sensor 222 is because the main body 2 is moved by the momentary upward movement.
（選択維持）
　次に、引き続き図６を用いて、表１（８）に示す、左足の踵を上げたままの場合（左クリック維持）について説明する。
　単純に足の踵を上下する場合、本体部２の前方向への傾きは一瞬であるため、加速度センサ２２１のＹ軸方向の検出値は大きく変化しない。しかしながら、足の踵を上げたままにすると、本体部２が前傾した状態が維持されることになる。このとき、加速度センサ２２１のＹ軸方向の検出値は、本体部２が前傾状態であることを判定する閾値を超えたままとなる。この閾値を超えている期間、制御部２１１は「左クリックする」の動作指示を決定し続ける。すなわち、コンピュータ５ではカーソル５２が左クリックされたまま、すなわち「左クリック維持」の状態となる。 (Maintain selection)
Next, the case where the heel of the left foot is kept raised (maintaining the left click) shown in Table 1 (8) will be described using FIG. 6 continuously.
When simply moving the heel of the foot up and down, the inclination of the main body 2 in the forward direction is instantaneous, so the detected value in the Y-axis direction of the acceleration sensor 221 does not change significantly. However, when the heel of the foot is kept raised, the body 2 is maintained in the forwardly inclined state. At this time, the detection value in the Y-axis direction of the acceleration sensor 221 still exceeds the threshold value for determining that the main body 2 is in the forward lean state. While the threshold is exceeded, the control unit 211 continues to determine the operation instruction of “left click”. That is, in the computer 5, the cursor 52 is left-clicked, that is, it is in the state of "left-click maintained".
　そして、閾値を超えている期間（制御部２１１が「左クリックする」の動作指示を決定し続けている状態、すなわち「左クリック維持」の状態）において、さらにユーザ４が左足を左に傾けたとする。これにより、本体部２が左に傾斜し、制御部２１１は、加速度センサ２２１から取得した検出値から、「カーソル 下移動」の動作指示を決定する。すなわち、制御部２１１は、「左クリックする」と「カーソル 下移動」との双方の動作指示の情報を生成する。これにより、コンピュータ５ではドラッグが行われる。その後、ユーザ４が左足の踵を下ろして、本体部２の傾きを基準軸の位置に戻すことでドラッグが解除される。 Then, the user 4 further leans the left foot to the left during a period exceeding the threshold (in a state where the control unit 211 continues to determine the operation instruction of “left click”, ie, “hold left click”). Do. As a result, the main unit 2 tilts to the left, and the control unit 211 determines an operation instruction of “move the cursor downward” from the detection value acquired from the acceleration sensor 221. That is, the control unit 211 generates information of operation instructions for both “left click” and “move cursor downward”. Thus, the drag is performed on the computer 5. Thereafter, the user 4 lowers the heel of the left foot and returns the tilt of the main body 2 to the position of the reference axis, whereby the drag is released.
　以上のように、ドラッグを行う足の動作は、左足の踵を上げて本体部２を前傾させたまま、足を左に傾けることとなる。これは、ユーザ４が立った状態である場合、左膝を前方に曲げることで容易にドラッグを行うことができるが、ユーザ４が座った状態である場合、少し難しい動作となる。そこで、座っている場合は、図７に示すように、まず左足の踵を上げてから、足のつま先を地面に擦るように後方に下げる。これにより、必然的に本体部２は前傾する。そのまま左足を左側に傾けることでドラッグを容易に行うことができる。 As described above, with the movement of the foot performing dragging, the foot is inclined to the left while raising the heel of the left foot and inclining the main body part 2 forward. This makes it possible to easily drag by bending the left knee forward when the user 4 is standing, but becomes a somewhat difficult operation when the user 4 is sitting. Therefore, when sitting down, as shown in FIG. 7, first raise the heel of the left foot, and then lower it backward so as to rub the toes of the foot on the ground. As a result, the main body 2 inevitably tilts forward. By dragging the left foot to the left as it is, dragging can be easily performed.
　同様に、足を傾ける場合、例えば、右膝や右足の付け根を支点として、右足の裏を地面に擦るように右に移動させることで、必然的に本体部２は左に傾く。このように足を動作させることで、ユーザ４が立った状態であっても、本発明のユーザ入力装置１を用いることで容易にカーソル５２に係る動作を制御することができる。 Similarly, when tilting the foot, for example, the body portion 2 is inevitably inclined to the left by moving the back of the right foot to the right with the bottom of the right foot and the base of the right foot as a fulcrum. By operating the foot in this manner, even when the user 4 is standing, the operation relating to the cursor 52 can be easily controlled by using the user input device 1 of the present invention.
　また、制御部２１１は、動作指示を決定した後に所定時間だけ判定処理をせず待機する場合がある。この待機処理が行われる所定時間は、加速度センサ２２１及びジャイロセンサ２２２の精度や検出値を取得する時間間隔により自由に設定が可能である。
　この制御部２１１が動作指示を決定した後に所定時間だけ判定処理をせず待機する場合について説明する。例えば、左足の踵を上げたとき、制御部２１１は左クリックの判定をする（時刻ｔ１）。このとき、検出部２２（加速度センサ２２１、ジャイロセンサ２２２）が検出値を出力する時間間隔が短いと、左足の踵を上げた動きが１回であるにもかかわらず、加速度センサ２２１及びジャイロセンサ２２２は何度も制御部２１１が左クリックの判定をする検出値を出力してしまう。 The control unit 211 may stand by without performing the determination process for a predetermined time after determining the operation instruction. The predetermined time for which the standby process is performed can be freely set by the accuracy of the acceleration sensor 221 and the gyro sensor 222 or the time interval for acquiring the detection value.
A case where the control unit 211 determines the operation instruction and stands by without performing the determination process for a predetermined time will be described. For example, when the heel of the left foot is raised, the control unit 211 determines left click (time t1). At this time, if the time interval at which the detection unit 22 (acceleration sensor 221, gyro sensor 222) outputs a detection value is short, the acceleration sensor 221 and the gyro sensor may be operated despite raising the heel of the left foot one time. The reference numeral 222 repeatedly outputs the detection value for the control unit 211 to determine the left click.
　そのため、制御部２１１は左クリックの判定をした後、所定時間だけ処理を待機する。つまり、この待機処理は、不連続な左クリックの動作指示を制御部２１１が何度も決定してしまい、コンピュータ５において左クリックが連打されることになるのを回避するためである。この待機処理が行われる所定時間内に、加速度センサ２２１及びジャイロセンサ２２２は、基準軸に位置する状態のときの検出値に安定する。この所定時間が経過した後で、再度左足の踵が上がったとき、制御部２１１は左クリックの判定をし（時刻ｔ２）、左クリックの動作指示を決定する。
　すなわち、待機処理が行われる所定時間は、ユーザが左足の踵を上げた直後の時刻から、左足の踵を下げて地面に接地して、本体部２（検出部２２）が基準軸に位置する状態、すなわち基準軸の傾きがなく安定した状態になる時刻までの時間を設定することが望ましい。 Therefore, after determining the left click, the control unit 211 stands by for a predetermined time. That is, in the standby process, the control unit 211 determines the operation instruction of the discontinuous left click many times to avoid that the left click is continuously hit in the computer 5. The acceleration sensor 221 and the gyro sensor 222 stabilize at the detection value in the state of being positioned on the reference axis within a predetermined time in which the standby process is performed. After the predetermined time has elapsed, when the heel of the left foot rises again, the control unit 211 determines left click (time t2), and determines a left click operation instruction.
That is, from the time immediately after the user lifts the heel of the left foot, the user turns the heel of the left foot down and touches the ground, and the main body 2 (detection unit 22) is positioned at the reference axis It is desirable to set a time, that is, a time until the time when the reference axis becomes stable without a tilt of the reference axis.
　ここで、この２連続の左クリックがダブルクリックとして判定されるようにする場合、時刻ｔ１から時刻ｔ２までの時間間隔は、コンピュータ５においてダブルクリックとして判定される時間間隔であることが望ましい。つまり、待機処理が行われる所定時間は、コンピュータ５においてダブルクリックとして判定される時間間隔よりも短くしておくことが望ましい。 Here, in the case where the two left clicks are determined as double clicks, it is preferable that the time interval from time t1 to time t2 be a time interval determined as the double click in the computer 5. That is, it is desirable that the predetermined time for which the standby process is performed be shorter than the time interval determined as a double click in the computer 5.
　また、所定時間だけ処理を待機する代わりに、制御部２１１は、加速度センサ２２１及びジャイロセンサ２２２からの検出値が所定範囲内の値になるまで、待機処理を行ってもよい。
　例えば、本体部２（検出部２２）が基準軸に位置する状態、すなわち基準軸の傾きがなく安定した状態に位置するときに、加速度センサ２２１及びジャイロセンサ２２２から取得する検出値を、安定検出値とする。この安定検出値を基準とした所定範囲内の値を予め記憶部２１２に記憶しておく。 Further, instead of waiting for the process for a predetermined time, the control unit 211 may perform the standby process until the detection values from the acceleration sensor 221 and the gyro sensor 222 become values within a predetermined range.
For example, when the main unit 2 (detection unit 22) is positioned on the reference axis, that is, in a stable state without inclination of the reference axis, the detection value acquired from the acceleration sensor 221 and the gyro sensor 222 is stably detected. It will be a value. A value within a predetermined range based on the stable detection value is stored in advance in the storage unit 212.
　そして、制御部２１１は、「左クリックする」の動作指示を決定した後に待機処理を実行開始する。その後、制御部２１１は、加速度センサ２２１及びジャイロセンサ２２２から取得する検出値が、安定検出値を基準とした所定範囲内の値となったときに、待機処理を終了する。そして、制御部２１１は、次の加速度センサ２２１及びジャイロセンサ２２２から取得する検出値が、クリックされたと判定する閾値を超えた場合に、次の「左クリックする」の動作指示を決定する。
　ここで、制御部２１１は、加速度センサ２２１及びジャイロセンサ２２２から取得する検出値が、複数回連続して、安定検出値を基準とした所定範囲内の値となったときに、待機処理を終了することが望ましい。 Then, after determining the operation instruction of “left click”, the control unit 211 starts executing the standby process. Thereafter, when the detection values acquired from the acceleration sensor 221 and the gyro sensor 222 become values within a predetermined range based on the stability detection value, the control unit 211 ends the standby processing. Then, the control unit 211 determines the next “left click” operation instruction when the detection values acquired from the next acceleration sensor 221 and the gyro sensor 222 exceed the threshold value determined to be clicked.
Here, the control unit 211 ends the standby process when the detection value acquired from the acceleration sensor 221 and the gyro sensor 222 becomes a value within a predetermined range based on the stable detection value continuously a plurality of times. It is desirable to do.
　表１に示すように、右足を右に傾けると共に左足を右に傾けることで、カーソル５２は表示画面５１にて右上に向かって移動する。このように、右足及び左足の動きを組み合わせることで、手で操作するマウスと同様の操作をすることができる。 As shown in Table 1, the cursor 52 moves toward the upper right on the display screen 51 by tilting the right foot to the right and tilting the left foot to the right. As described above, by combining the movement of the right foot and the left foot, the same operation as a hand-operated mouse can be performed.
　以上のように、本発明のユーザ入力装置１は、足を傾けたり、踵を上下に動かしたりといった単純な動きで、コンピュータ５が備える表示画面５１に表示されたカーソル５２に係る動作を容易に操作することができる。すなわち、一方の動作指示部（例えば、右足首に装着された入力装置１１の動作指示部２１）が決定する動作指示のパターンと、他方の動作指示部（例えば、左足首に装着された入力装置１２の動作指示部２２）が決定する動作指示のパターンとは、カーソル５２に係る動作の各パターンを実行可能にする。 As described above, the user input device 1 of the present invention can easily perform an operation related to the cursor 52 displayed on the display screen 51 provided in the computer 5 by a simple movement such as tilting the foot or moving the eyelid up and down. It can be operated. That is, a pattern of operation instructions determined by one operation instruction unit (for example, operation instruction unit 21 of input device 11 attached to the right ankle) and the other operation instruction unit (for example, input device attached to the left ankle) The operation instruction pattern determined by the 12 operation instruction units 22) enables execution of each pattern of the operation related to the cursor 52.
　本発明は、前記した実施形態に限定されることなく、本発明の要旨を逸脱しない範囲で種々の変更や変形を行うことができる。特に、本発明は、マウス以外のデバイス、例えばキーボードやコントローラ等のデバイスとしても利用することができる。
　例えば、本実施形態では、入力装置１１，１２を、図２では、箱状の本体部２とベルト状の装着部３とで示したが、本体部２と装着部３とが一体化していても構わない。例えば、靴下やブーツ等のように足に履いて装着するものや、クリップ等のように足首を挟んで足に装着するもの、本体部２が足輪に内蔵されたもの等であっても構わない。 The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention. In particular, the present invention can also be used as a device other than a mouse, for example, a device such as a keyboard or a controller.
For example, in the present embodiment, although the input devices 11 and 12 are shown by the box-like main body 2 and the belt-like attachment 3 in FIG. 2, the main body 2 and the attachment 3 are integrated. I don't care. For example, they may be worn by putting on the foot like socks or boots, those attached to the foot across the ankle like clips etc, or those with the main body 2 built in the foot ring etc. Absent.
　また、本実施形態では、足の動きを、前後左右に足を傾ける動きと、足の踵を上げる動きとを判定する内容を説明したが、足の他の動きであっても構わない。例えば、足首を左右にねじる動きや、足を大きく蹴りだす動き等による本体部２の動きを制御部２１１が判定しても構わない。例えば、足を大きく蹴りだす動きは、足の踵を上げる動きよりも前方向に大きく動くため、ジャイロセンサ２２２のＹ軸方向の検出値から制御部２１１は判定することができる。これにより、例えば、ユーザ４の歩き出しを検出した制御部２１１がその後の動作指示をしないという、スリープ機能をユーザ入力装置１は備えることができる。 Further, in the present embodiment, the content of determining the movement of the foot, that is, the movement of inclining the foot back and forth and right and the movement of raising the heel of the foot has been described. For example, the control unit 211 may determine the movement of the main body 2 due to, for example, a movement of twisting the ankle to the left or right, a movement of sharply kicking a foot, or the like. For example, since the movement of largely kicking the foot moves in the forward direction more than the movement of raising the heel of the foot, the control unit 211 can determine it from the detection value in the Y-axis direction of the gyro sensor 222. Thus, for example, the user input device 1 can be provided with a sleep function in which the control unit 211 that has detected the start of the user 4 does not instruct the operation thereafter.
　例えば、このスリープ機能と、例えばダブルクリックすることでスリープ機能を解除するスリープ解除機能とをユーザ入力装置１が備えてもよい。このスリープ機能を備えるユーザ入力装置１を足に装着したユーザ４は、講演会等において壇上に立ってプレゼンテーションを行う場合に、コンピュータ５を操作する操作者に指示や合図等をする必要がない。直立した姿勢のユーザ４は、足を動かしてコンピュータ５を遠隔操作して、スクリーンに表示されたカーソル５２に係る動作を制御することができるからである。遠隔操作するための機器を手で持たないため、ユーザ４は両手を自由に使ってジェスチャーすることができ、より観客にアピールすることができる。 For example, the user input device 1 may include the sleep function and a sleep release function that releases the sleep function by double-clicking, for example. The user 4 who wears the user input device 1 having the sleep function on his / her foot does not need to give instructions or signals to the operator who operates the computer 5 when giving a presentation on a stage at a lecture or the like. This is because the user 4 in the upright posture can move his / her foot to remotely control the computer 5 to control the operation of the cursor 52 displayed on the screen. Since the user does not hold the device for remote control by hand, the user 4 can freely make gestures with both hands, which can further appeal to the audience.
　また、検出部２２は、加速度センサ２２１とジャイロセンサ２２２との他に、磁気センサや赤外線センサ等を備えてもよい。また、加速度センサ２２１とジャイロセンサ２２２とを複数備えてもよい。このように複数種類のセンサ、複数のセンサを備えることで、制御部２１１は、本体部２が基準軸の位置からどのように動いたのか、センサの数だけ検出内容を取得することができる。これにより、カーソルの移動速度を調整する等の細かい動作指示だけでなく、複雑な足の動きを判定することができる。これにより、制御部２１１は検出内容に応じて、ウェブブラウザに対して「戻る」「進む」等の指示や、ショートカットキーに対応した指示等をコンピュータ５に送信することができる。 In addition to the acceleration sensor 221 and the gyro sensor 222, the detection unit 22 may include a magnetic sensor, an infrared sensor, and the like. Also, a plurality of acceleration sensors 221 and gyro sensors 222 may be provided. As described above, by providing the plurality of types of sensors and the plurality of sensors, the control unit 211 can acquire the detection content as many as the number of sensors as how the main body unit 2 moved from the position of the reference axis. This makes it possible to determine not only detailed motion instructions such as adjusting the moving speed of the cursor, but also complicated foot movements. Thus, the control unit 211 can transmit to the computer 5 an instruction such as “return” or “advance” or an instruction corresponding to the shortcut key to the web browser according to the detection content.
　また、本実施形態において、制御部２１１は、加速度センサ２２１から得られる検出値から、カーソル５２の移動速度を決定しているが、制御部２１１は、ジャイロセンサ２２２から得られる検出値と組み合わせて、カーソル５２の移動速度を決定してもよい。これにより、制御部２１１は、加速度センサ２２１の検出値から決定したカーソル５２の移動速度に、ジャイロセンサ２２２の検出値から決定したカーソル５２の移動速度を加えることで、ジャイロセンサ２２２の検出値に応じて、カーソル５２の移動速度をさらに加速させたり、減速させたりすることができる。 Further, in the present embodiment, the control unit 211 determines the moving speed of the cursor 52 from the detection value obtained from the acceleration sensor 221, but the control unit 211 combines with the detection value obtained from the gyro sensor 222. The movement speed of the cursor 52 may be determined. Thereby, the control unit 211 adds the moving speed of the cursor 52 determined from the detection value of the gyro sensor 222 to the moving speed of the cursor 52 determined from the detection value of the acceleration sensor 221 to make the detection value of the gyro sensor 222 Accordingly, the moving speed of the cursor 52 can be further accelerated or decelerated.
　また、ユーザ入力装置１から送信される指示に対応して、コンピュータ５で指示に応じた操作が実行されるデバイスドライバを予めコンピュータ５にインストールしておいても構わない。このデバイスドライバを用いることで、動作指示部２１が決定する動作指示のパターンをさらに多くすることができる。これにより、ユーザ入力装置１はコンピュータ５に対して複雑な入力が可能なデバイスとなる。 Further, in response to an instruction transmitted from the user input device 1, a device driver may be previously installed in the computer 5 in which an operation according to the instruction is executed by the computer 5. By using this device driver, the number of operation instruction patterns determined by the operation instruction unit 21 can be further increased. As a result, the user input device 1 becomes a device capable of complicated input to the computer 5.
　また、足に装着して操作するため、従来のマウスを手で操作することが原因による腱鞘炎の発症を避けることができる。
　また、衛生面や作業工程上、手でキーボードやマウスを触れることができないユーザであっても、足でコンピュータ５を操作することができる。例えば医療従事者は、手袋を装着した両手で医療器具や医療用マシンなどを操りながら、足でコンピュータ５を操作することができる。他にも手袋をして作業する場合がある調理者や薬剤師、工場内作業者など、荷物を抱えた配達員なども、手を使わずに足でコンピュータ５を操作することができる。 In addition, since the conventional mouse is operated by hand because it is worn on the foot and operated, it is possible to avoid the onset of tendinitis due to the cause.
In addition, even a user who can not touch the keyboard or mouse by hand can operate the computer 5 with his / her foot in terms of hygiene and work processes. For example, a medical worker can operate the computer 5 with his / her feet while operating a medical instrument or a medical machine with both hands wearing gloves. In addition, a cook who may work with gloves, a pharmacist, a worker in a factory, a delivery person holding a luggage, etc. can operate the computer 5 with his / her feet without using his / her hands.
　また、ネットワーク９に有線のＵＳＢケーブルを用いる場合、本体部２は電源部を必要としない。動作指示部２１と検出部２２と通信部２３とは、ＵＳＢケーブルで接続されたコンピュータ５からの電力が供給されることで動作する。例えば、デスクの下に置かれたデスクトップパソコンをコンピュータ５とした場合、デスクの下でＵＳＢケーブルが動くため、デスクの上にて手で操作するマウスと異なり、ユーザ４が操作時にＵＳＢケーブルを邪魔に思うことがない。 When a wired USB cable is used for the network 9, the main unit 2 does not need a power supply unit. The operation instruction unit 21, the detection unit 22, and the communication unit 23 operate by being supplied with power from the computer 5 connected by the USB cable. For example, when the desktop PC placed under the desk is the computer 5, the USB cable moves under the desk, so unlike the mouse operated by hand on the desk, the user 4 disturbs the USB cable at the time of operation I have no idea
　また、本体部２１に、通信部２３が無線ＬＡＮ等の無線ネットワークと、ＵＳＢケーブル等の有線ネットワークとのどちらか一方で通信を行うように切り替えるスイッチを備えてもよい。これにより、自宅や社内等では有線ネットワークを用いてコンピュータ５と接続し、外出先では無線ネットワークを用いてコンピュータ５と接続するということができる。 In addition, the main body unit 21 may be equipped with a switch for switching such that the communication unit 23 communicates with either a wireless network such as a wireless LAN or a wired network such as a USB cable. As a result, it is possible to connect to the computer 5 using a wired network at home, in the office, etc., and to connect to the computer 5 using a wireless network when away from home.
　コンピュータ５は、ノートパソコン(Laptop)やデスクトップパソコンだけでなく、タブレット端末やサーバ、スマートフォン、ゲーム機等であってもよい。ここで、コンピュータ５がゲーム機であれば、カーソル５２は十字キーにより動作されるキャラクター等の操作対象である。 The computer 5 may be not only a laptop computer (Laptop) or a desktop computer, but also a tablet terminal, a server, a smartphone, a game machine, or the like. Here, if the computer 5 is a game machine, the cursor 52 is an operation target such as a character operated by the cross key.
