[0005] A first example aspect provided by the present disclosure is a user interface device, comprising: A movable body and A display device; a control device that causes the display device to display a plurality of first icon images, each of which is associated with a specific function; It is equipped with The control device placing one of the plurality of first icon images in a selected state in accordance with an approach or contact position of the object to be detected relative to the movable body; When the movable body is displaced in a first direction while the one first icon image is in the selected state, a plurality of second icon images, each associated with a sub-function of the specific function, are displayed at positions shifted in the first direction from the one first icon image on the display device.

[0007] A third example aspect provided by the present disclosure is a computer program executable by a processor installed in a control device, By being executed, the control device receiving a detection signal indicating the approach or contact position of the object to be detected relative to the movable body; displaying a plurality of first icon images on a display device, each of which is associated with a specific function; placing one of the plurality of first icon images in a selected state based on the detection signal; When the movable body is displaced in a first direction while the one first icon image is in the selected state, a plurality of second icon images, each associated with a sub-function of the specific function, are displayed at positions shifted in the first direction from the one first icon image on the display device.

[0008] According to the configurations of the first to third aspects, by combining the change in the position of the detected object relative to the movable body and the displacement of the movable body in the first direction, it is possible to efficiently repeat the operation of selecting one of multiple icon images presented as options for a specific function and the operation of displaying options for sub-functions of the selected specific function. In addition, since the position where the options for the sub-function are displayed is shifted in the same direction as the displacement direction of the movable body relative to the position where the options for the superordinate function are displayed, an intuitive operating experience can be provided to the occupant. Therefore, the operability of the user interface device can be improved.

[0009] A fourth example aspect provided by the present disclosure is a user interface device, A movable body and A display device; a control device that causes the display device to display a plurality of first icon images, each associated with a specific function, and a plurality of second icon images, each associated with a sub-function of the specific function; It is equipped with The control device displaying the second icon images at positions shifted in a first direction from the first icon images on the display device; one of the plurality of second icon images is set to a selected state in accordance with an approach or contact position of the object to be detected relative to the movable body; When the movable body is displaced in a second direction opposite to the first direction while the one second icon image is in the selected state, one of the plurality of first icon images that is located at a position shifted in the second direction from the one second icon image on the display device is set to the selected state.

[0010] A fifth example aspect provided by the present disclosure is a control device, an interface that receives a detection signal indicating an approaching or contacting position of an object to be detected relative to a movable body; a processor that displays, on a display device, a plurality of first icon images, each associated with a specific function, and a plurality of second icon images, each associated with a sub-function of the specific function; It is equipped with The processor: displaying the second icon images at positions shifted in a first direction from the first icon images on the display device; placing one of the plurality of second icon images in a selected state based on the detection signal; When the movable body is displaced in a second direction opposite to the first direction while the one second icon image is in the selected state, one of the plurality of first icon images that is located at a position shifted in the second direction from the one second icon image on the display device is set to the selected state.

[0011] A sixth example aspect provided by the present disclosure is a computer program executable by a processor installed in a control device, By being executed, the control device receiving a detection signal indicating the approach or contact position of the object to be detected relative to the movable body; displaying, on a display device, a plurality of first icon images each associated with a specific function and a plurality of second icon images each associated with a sub-function of the specific function; displaying the second icon images at positions shifted in a first direction from the first icon images on the display device; placing one of the plurality of second icon images in a selected state based on the detection signal; When the movable body is displaced in a second direction opposite to the first direction while the one second icon image is in the selected state, one of the plurality of first icon images that is located at a position shifted in the second direction from the one second icon image on the display device is set to the selected state.

[0012] According to the configurations of the fourth to sixth examples, by displacing the movable body in the second direction, it is possible to transition to a state in which one of multiple icon images associated with a higher-level function can be selected, eliminating the need to retrace the path that led to the final icon image selection while changing the position of the detected object relative to the movable body. In other words, the path leading to the selection of one of multiple icon images associated with a lower-level function may differ from the path taken to transition to a state in which one of multiple icon images associated with a higher-level function can be selected, and the shortest path is selected for the latter. Since the state in which the higher-level function can be selected is restored with a minimum of operations, the operability of the user interface device can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0014] The following detailed description of exemplary embodiments will be given with reference to the accompanying drawings. In the drawings used in the following description, the scale has been changed appropriately so that each element can be clearly seen.

[0015] Fig. 1 illustrates an example of the functional configuration of a user interface device 10 according to one embodiment. The user interface device 10 according to this example is configured to be mounted on a vehicle 20 illustrated in Fig. 2. The user interface device 10 is a device for controlling the operation of a controlled device mounted on the vehicle 20. Examples of the controlled device include air conditioning equipment, audiovisual equipment, lighting equipment, a steering column position adjustment device, a seat position adjustment device, and a door mirror position adjustment device.

[0016] 1 and 2, the user interface device 10 includes a knob 11 and a display device 12. In this example, the knob 11 and the display device 12 are disposed in a center cluster 21 of a vehicle 20. The knob 11 is disposed below the display device 12.

[0017] The knob 11 is configured to be operable by the occupant's fingers F. Fig. 3 illustrates an example of the appearance of the knob 11. Fig. 4 illustrates an example of the contour shape of the knob 11 as viewed from the direction of arrow IV in Fig. 3.

[0018] As illustrated in Fig. 4, the knob 11 is configured to be rotatable in the counterclockwise and clockwise directions in Fig. 1 around an axis A. When the occupant applies force in either direction with the finger F, the knob 11 rotates in that direction. When the force from the finger F is released, the knob 11 returns to its initial position by a return mechanism (not shown) such as a spring.

[0019] In the following description, the clockwise direction in Fig. 4 will be referred to as the upward direction, and the counterclockwise direction in Fig. 4 will be referred to as the downward direction. The knob 11 is an example of a movable body. Rotation is an example of displacement.

[0020] 5 illustrates an example of a screen 120 displayed on the display device 12. In this example, the screen 120 includes a plurality of first icon images 121a to 121g. The plurality of first icon images 121a to 121g are arranged in the left-right direction at the bottom end of the screen 120. Each of the plurality of first icon images 121a to 121g is associated with a specific function related to a controlled device mounted on the vehicle 20.

[0021] 4, the knob 11 includes a detection unit 111. The detection unit 111 is disposed at a position on the surface of the knob 11 where the occupant's finger F can touch it. The detection unit 111 is made of a conductive material.

[0022] As illustrated in FIG. 1 , the user interface device 10 includes a first sensor 131. When an occupant's finger F comes into contact with the detection unit 111, a change in capacitance occurs in the detection unit 111. The first sensor 131 is configured to detect the change and output a first detection signal DT1 corresponding to the change. The first sensor 131 can be realized by an electrostatic sensor having a well-known configuration. The occupant's finger is an example of an object to be detected. The first detection signal DT1 may be an analog signal or a digital signal.

[0023] The user interface device 10 includes a second sensor 132. The second sensor 132 is configured to detect an upward displacement of the knob 11. The upward direction is an example of a first direction. The displacement can be detected mechanically, electrically, optically, or magnetically using a known configuration. The second sensor 132 is configured to output a second detection signal DT2 when it detects an upward displacement of the knob 11. The second detection signal DT2 may be an analog signal or a digital signal.

[0024] The user interface device 10 includes a third sensor 133. The third sensor 133 is configured to detect a downward displacement of the knob 11. The downward direction is an example of the second direction. The displacement can be detected mechanically, electrically, optically, or magnetically using a known configuration. The third sensor 133 is configured to output a third detection signal DT3 when it detects a downward displacement of the knob 11. The third detection signal DT3 may be an analog signal or a digital signal.

[0025] The user interface device 10 includes a control device 14. The control device 14 includes a reception interface 141, a processor 142, and an output interface 143.

[0026] The receiving interface 141 is configured to be able to receive the first detection signal DT1, the second detection signal DT2, and the third detection signal DT3. If at least one of the first detection signal DT1, the second detection signal DT2, and the third detection signal DT3 is an analog signal, the receiving interface 141 includes an appropriate conversion circuit including an A / D converter.

[0027] The processor 142 is configured to output a display control signal DC, which controls the state of the screen 120 displayed on the display device 12, from the output interface 143. The display control signal DC may be an analog signal or a digital signal. When the display control signal DC is an analog signal, the output interface 143 includes an appropriate conversion circuit including a D / A converter. The display device 12 is configured to change the state of the screen 120 in response to the display control signal DC.

[0028] The processor 142 is configured to output a display control signal DC from the output interface 143 to set one of the multiple first icon images 121a to 121g displayed on the display device 12 to a selected state, depending on the position at which the approach or contact of the occupant's finger F is detected in the detection section 111 of the knob 11 indicated by the first detection signal DT1.

[0029] 6, the processor 142 outputs a display control signal DC, which sets to a selected state a first icon image located above the position where the approach or contact of the occupant's finger F is detected in the detection unit 111 of the knob 11, from the output interface 143. In this example, the first icon image 121g is set to a selected state.

[0030] The change to the selected state can be realized by changing the color of the icon image, changing the shape of the icon image, changing the size of the icon image, displaying auxiliary text, or the like.

[0031] 7, when the position of the finger F in the detection unit 111 is changed, the first icon image in the selected state is also changed. In this example, the first icon image 121d located above the moved finger F is in the selected state. The selected state of the first icon image 121g is released.

[0032] When the reception interface 141 receives the second detection signal DT2 after the display control signal DC that sets a specific first icon image to a selected state is output, the processor 142 is configured to output, from the output interface 143, a display control signal DC that displays a plurality of second icon images at positions shifted upward from the first icon image. Each of the plurality of second icon images is associated with a sub-function of the function associated with the first icon image that has been set to a selected state.

[0033] 8, when the knob 11 is displaced upward while the first icon image 121d is in the selected state, a plurality of second icon images 122a-122d are displayed at positions shifted upward from the first icon image 121d. Each of the plurality of second icon images 122a-122d is associated with a sub-function of the specific function with which the first icon image 121d is associated. The plurality of second icon images 122a-122d are arranged in the left-right direction.

[0034] For example, if the first icon image 121d is associated with the "seat adjustment" function, the multiple second icon images 122a to 122d may be associated with "position adjustment," "recline angle adjustment," "headrest position adjustment," and "armrest position adjustment," respectively.

[0035] In addition, among the plurality of second icon images 122a to 122d, the second icon image 122b located above the finger F is in a selected state.

[0036] As in the case of the first icon image, when the position of the finger F in the detection unit 111 is changed as illustrated in Fig. 9, the second icon image that is in the selected state is also changed. In this example, the second icon image 122c that is located above the moved finger F is in the selected state. The selected state of the second icon image 122b is released.

[0037] When the reception interface 141 receives the second detection signal DT2 after the display control signal DC that sets a specific second icon image to a selected state is output, the processor 142 is configured to output, from the output interface 143, a display control signal DC that displays a plurality of third icon images at positions shifted upward from the second icon image. Each of the plurality of third icon images is associated with a sub-function of the function associated with the second icon image that has been set to a selected state.

[0038] 10, when the knob 11 is displaced upward while the second icon image 122c is in the selected state, a plurality of third icon images 123a-123c are displayed at positions shifted upward from the second icon image 122c. Each of the plurality of third icon images 123a-123c is associated with a sub-function of the specific function with which the second icon image 122c is associated. The plurality of third icon images 123a-123c are arranged in the left-right direction.

[0039] As described above, the second icon image 122c is associated with the "headrest position adjustment" function. In this case, the third icon images 123a to 123c can be associated with "up," "reset to initial position," and "down," respectively.

[0040] As with the first and second icon images, when the position of the finger F in the detection unit 111 is changed as illustrated in Fig. 11, the third icon image that is in the selected state is also changed. In this example, the third icon image 123c that is located above the moved finger F is in the selected state. The selected state of the third icon image 123b is released.

[0041] The processor 142 is configured to execute a process of finalizing the selection of the function associated with the selected icon image when it determines, based on the first detection signal DT1, that the finger F has been released from the knob 11. In the example shown in Fig. 12, the selected state of the third icon image 123c is finalized. The selected states of the first icon image 121d and the second icon image 122c may be released or maintained.

[0042] 1, the processor 142 is configured to output a control signal CT that causes the controlled device to execute a selected function from the output interface 143. In the above example, the control signal CT that causes the drive mechanism provided in the seat to lower the armrest associated with the third icon image 123c is output from the output interface 143.

[0043] According to the above configuration, by combining a change in the position of the finger F relative to the knob 11 with an upward displacement of the knob 11, the operation of selecting one of a plurality of icon images presented as options for a specific function and the operation of displaying options for sub-functions of the selected specific function can be efficiently repeated. In addition, the position where the options for the sub-function are displayed shifts in the same direction as the displacement direction of the knob 11 relative to the position where the options for the superordinate function are displayed, providing the occupant with an intuitive operating experience. Therefore, the operability of the user interface device 10 can be improved.

[0044] Furthermore, since the direction in which the multiple icon images are arranged is different from the direction in which the knob 11 is moved, the operation of selecting an icon image can be clearly distinguished from the operation of displaying options for sub-functions, which also contributes to improving the operability of the user interface device 10.

[0045] In addition, when the reception interface 141 receives the second detection signal DT2 after the display control signal DC that sets a specific second icon image to a selected state is output, the reception interface 141 may be configured to output a display control signal DC from the output interface 143 that displays multiple third icon images in place of the second icon image.

[0046] For example, as illustrated in Figures 13 and 14, when the knob 11 is displaced upward while the second icon image 122c is in the selected state, multiple third icon images 123a to 123c are displayed in the same position in place of the multiple second icon images 122a to 122d.

[0047] In other words, when an icon image relating to a certain sub-function exists that is associated with a higher-level function and an icon image associated with a lower-level function, and the icon image associated with the lower-level function is displayed, the display of the intermediate icon image relating to the sub-function is omitted.

[0048] According to this configuration, when the functions associated with the icon images have a hierarchical structure of three or more layers, it is possible to prevent the area of ​​the area for displaying the icon images on the screen 120 from increasing more than necessary. This prevents a decrease in the visibility of the screen 120, thereby improving the operability of the user interface device 10.

[0049] The processor 142 is configured to output, from the output interface 143, a display control signal DC that changes a second icon image that is located in a position shifted downward from the third icon image among the plurality of second icon images to a selected state when the reception interface 141 receives a third detection signal DT3 after a display control signal DC that changes a specific third icon image to a selected state.

[0050] 15, when the knob 11 is displaced downward while the third icon image 123c is in the selected state, the second icon image 122d, which is shifted downward from the third icon image 123c, is placed in the selected state. The third icon images 123a to 123c are erased.

[0051] When the reception interface 141 receives a third detection signal DT3 after a display control signal DC that sets a specific second icon image to a selected state is output, the processor 142 is configured to output, from the output interface 143, a display control signal DC that sets a first icon image that is located at a position shifted downward from the second icon image among the multiple first icon images to a selected state.

[0052] 16, if the knob 11 is displaced downward while the second icon image 122d is in the selected state, the first icon image 121f, which is shifted downward from the second icon image 122d, is placed in the selected state. The second icon images 122a to 122d are erased.

[0053] With this configuration, by displacing the knob 11 downward, it is possible to transition to a state in which one of multiple icon images associated with a higher-level function can be selected, and there is no need to retrace the path that led to the final icon image selection while changing the position of the finger F relative to the knob 11. In other words, the path taken to select one of multiple icon images associated with a lower-level function may differ from the path taken to transition to a state in which one of multiple icon images associated with a higher-level function can be selected, and the shortest path is selected for the latter. Since the state in which a higher-level function can be selected is restored with the minimum necessary operation, the operability of the user interface device 10 can be improved.

[0054] The control device 14 having the various functions described above can be realized by a dedicated integrated circuit such as a microcontroller, ASIC, or FPGA that includes a storage element pre-installed with a computer program for realizing the functions. In this case, the storage element is an example of a non-transitory computer-readable medium on which a computer program is stored.

[0055] Alternatively, the control device 14 may be realized by a general-purpose microprocessor operating in cooperation with general-purpose memory. Examples of the general-purpose microprocessor include a CPU, an MPU, and a GPU. Examples of the general-purpose memory include a ROM and a RAM. In this case, a computer program for realizing the function may be stored in the ROM. The general-purpose microprocessor specifies at least a portion of the program stored in the ROM, expands it in the RAM, and executes the above-described processing in cooperation with the RAM. In this case, the general-purpose memory is an example of a non-transitory computer-readable medium on which a computer program is stored.

[0056] The controller 14 may be implemented by a combination of a general purpose microprocessor and a dedicated integrated circuit.

[0057] The above-described embodiments are merely examples for facilitating understanding of the present disclosure. The configurations according to the above-described embodiments may be modified as appropriate without departing from the spirit of the present disclosure.

[0058] In the above embodiment, when the knob 11 is displaced upward while one of the plurality of first icon images 121a to 121g is in a selected state, the plurality of second icon images are displayed at positions shifted upward from the one first icon image. However, the configurations illustrated in Figures 17 and 18 may also be adopted.

[0059] Specifically, when the knob 11 is displaced downward while one of the plurality of first icon images 121a to 121g is in a selected state, the plurality of second icon images are displayed at positions shifted downward from the one first icon image. That is, the downward direction in this example is an example of the first direction.

[0060] In this case, when the knob 11 is displaced upward while an icon image associated with a certain sub-function is in the selected state, an icon image associated with a higher-level function that is shifted upward from the selected icon image is also in the selected state. In other words, the upward direction in this example is an example of the second direction.

[0061] The user interface device 10 may be mounted on a moving object other than the vehicle 20. Examples of such moving objects include trains, airplanes, ships, etc. The moving object may not require a driver.

[0062] The user interface device 10 does not need to be mounted on a mobile object, and can be used to control the operation of any appropriate controlled device installed in a home or facility.

[0063] The knob 11 does not necessarily need to be operated by the user's finger F. The knob 11 may be configured to be operated by another body part or an appropriate tool, as long as it can cause a change in capacitance in the detection unit 111 that is detected by the first sensor 131.

[0064] In the above embodiment, knob 11 is configured as a lever that can rotate around axis A. However, knob 11 may also be configured as a slider that slides linearly or a dial that can rotate around an axis, as long as it is displaceable in two directions that correspond to different operations in the controlled device.

[0065] In the above embodiment, the second direction is the opposite direction to the first direction. However, the first direction and the second direction do not necessarily have to be opposite directions. The first direction and the second direction may be different as long as they correspond to different operations in the controlled device. [Explanation of symbols]
