<< 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.

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).

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.

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.

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.

(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.

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.

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.

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.

«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.

(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.

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.

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.

(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.

(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.

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.

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).

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.

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.

(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.

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.

(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.

(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".

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.
