[0012] Problems to be solved by the invention:

[0013] The knob of KoD can be detached and attached, and can also be attached to the back of the display. Therefore, it is highly customizable in terms of changing the setting position on the touch panel or replacing the knob itself with a knob of a different design. It is envisioned that the customization of KoD can be used to replace the knob with a variety of knobs according to each car model or user's preference.

[0014] In this case, there is a case where it is desired not only to change the shape of the knob but also to freely change the installation position of the knob with respect to the entire display screen. Figure 3 The present invention shows the existing process for changing / updating the setting position of a knob. First, the user sticks the attached knob or the replacement knob on the display by adhesive or the like (S10). Next, the user performs input processing for writing the coordinates of the setting position of the knob to the operation unit for detecting the knob operation (S20). After writing the coordinates of the setting position, the operation of the knob by the user is detected (S30).

[0015] As described above, when a new knob is installed, the user must write the coordinates of the knob's setting position to the computing unit side every time and update the original coordinates. This operation is very troublesome and creates a burden when replacing the knob, which impairs customization. Therefore, a method is needed to facilitate the update of the knob's setting position when the knob is installed.

[0016] The present invention is to solve such conventional problems, and an object of the present invention is to provide an input device capable of determining the installation position of an operating element.

[0019] In one embodiment, the conductive component is arranged diagonally relative to the rotation center of the operating member, the detection mechanism detects the position of the diagonal conductive component, the judgment mechanism calculates the center point of the detected diagonal conductive component position, and judges the calculated center point as the setting position of the operating member. In one embodiment, the detection mechanism detects the trajectory of the position of the rotationally moving conductive component, the judgment mechanism calculates the rotation center of the conductive component based on the trajectory of the detected position of the conductive component, and judges the calculated rotation center as the setting position of the operating member. In one embodiment, the input device further includes: an operation detection unit that detects the operation of the operating member based on the setting position of the operating member judged by the judgment mechanism. In one embodiment, the judgment mechanism updates the setting position of the operating member stored in the operation detection unit.

[0020] The method for determining the setting position of an operating member of the present invention is a determination method in an input device, the input device comprising: a display comprising an electrostatic capacitance type touch sensor; and an operating member rotatably mounted on the display, the operating member internally comprising at least one conductive component that can capacitively couple with the touch sensor and rotate when the operating member rotates, the determination method comprising: a step of detecting the position of the conductive component based on a change in electrostatic capacitance when the operating member is operated; and a step of determining the setting position of the operating member based on the detected position of the conductive component.

[0021] In one embodiment, the conductive member is arranged diagonally with respect to the rotation center of the operating member, and in the step of detecting, the position of the diagonal position of the conductive member is detected, and in the step of judging, the center point of the detected diagonal position of the conductive member is calculated, and the calculated center point is judged as the setting position of the operating member. In one embodiment, in the step of detecting, the trajectory of the position of the rotationally moving conductive member is detected, and in the step of judging, the rotation center of the conductive member is calculated based on the trajectory of the detected position of the conductive member, and the calculated rotation center is judged as the setting position of the operating member.

[0051] The embodiment of the present invention is described. The input device of the present invention relates to a KoD mounted on a display including an electrostatic capacitive touch panel (touch sensor), providing a human-machine input interface. The KoD can be freely installed at any position on the display, and its shape, size, number, etc. are not particularly limited.

[0052] Figure 4 (A) is a schematic longitudinal cross-sectional view of a knob used in the input device of the present invention, Figure 2 The same reference numerals are attached to the same components as (A) and (B). The knob 20A according to the present embodiment is mounted at any position on the touch panel including the touch sensor 30 and the protective glass 32 by using an adhesive 34 or the like. The knob 20A is configured to include a cylindrical fixed portion 40 and a cylindrical rotating portion 60 rotatably mounted on the fixed portion 40 via a shaft 50. The bottom surface of the fixed portion 40 is fixed to the protective glass 32 via an adhesive 34.

[0053] The fixed part 40 and the rotating part 60 are made of, for example, an electrically insulating material, and a metal conductor 70 is provided inside the rotating part 60. The conductor 70 is provided inside the rotating part 60 so as to rotate together when the rotating part 60 rotates. In addition, the conductor 70 is capacitively coupled with the touch sensor 32. In a certain embodiment, the conductor 70 has: a thin plate-shaped circular part 70A having a diameter substantially equal to the diameter of the rotating part 60, and a pair of columnar parts 70B and 70C extending in the plumb direction from the diagonal position of the thin plate-shaped circular part 70A (i.e., a position 180° away from the rotating shaft 50 as the center). The shape, size, etc. of the pair of columnar parts 70B and 70C are not particularly limited. For example, the columnar parts are configured to extend in a cylindrical shape. In addition, the columnar parts 70B and 70C may be formed integrally with the thin plate-shaped circular part 70A, or may be configured to be connected to the thin plate-shaped circular part 70A.

[0054] The front ends of the columnar portions 70B and 70C extend beyond the bottom surface of the rotating portion 60 and are located in contact with or close to the surface of the fixed portion 40. When the rotating portion 60 rotates about the shaft 50, the conductor 70 also rotates together, and the front ends of the columnar portions 70B and 70C rotate and move in a manner that describes an arc on the surface of the fixed portion 40.

[0055] like Figure 4 As shown, when the user pinches the side of the knob 20A with two fingers F, a conductive path K1 passing through the fingers F and the thin plate-like circular part 70A, and the columnar part 70B, and a conductive path K2 passing through the fingers F and the thin plate-like circular part 70A, and the columnar part 70C are formed. According to the changes in the electrostatic capacitance on the conductive paths K1 and K2, the positions of the columnar parts 70B and 70C can be detected by the touch sensor 30.

[0056] In this embodiment, whether or not a knob is provided and where the knob is provided are determined based on (1) the size of the electrostatic capacitance and (2) the distribution shape of the detection coordinates. The general situation of this determination is as follows.

[0057] (1) Size of electrostatic capacitance

[0058] Generally speaking, the electrostatic capacitance detected when the knob 20A is pinched with a finger is smaller than when the display is directly touched with a finger. This is because Figure 4 As shown, various knob components (fixed parts, adhesives, etc.) are interposed between the finger F and the touch sensor 34. Therefore, by setting a threshold value according to the detection value of the electrostatic capacitance via the knob 20A, it is determined that the touch on the display is not by a finger but by a touch on the knob, that is, the knob is provided or mounted.

[0059] (2) Distribution shape of detection coordinates

[0060] like Figure 4 As shown, the conductor 70 built into the knob 20A has a thin plate-shaped circular portion 70A and a pair of columnar portions 70B and 70C arranged at diagonal positions thereof. The distribution shape of the detection points is fixed according to the position of the conductor when the knob 20A is pinched with fingers F.

[0061] Figure 5A Detection distribution of electrostatic capacitance detected by the touch sensor 30 when the knob 20A is pinched by a finger F is shown. The electrostatic capacitance value S1 with a small value corresponds to the position of the finger F close to the touch sensor, and the electrostatic capacitance value S2 with a large value corresponds to the position of the two columnar portions 70B and 70C of the conductor 70. The two columnar portions 70B and 70C are capacitively coupled with the touch sensor 30, and the touch sensor 30 detects the two electrostatic capacitance values ​​S2 corresponding to the columnar portions 70B and 70C.

[0062] Since two columnar portions 70B and 70C are located diagonally to the rotation center of circular portion 70A, the size of knob 20A and the center point of knob 20A can be calculated based on the diagonal positions of columnar portions 70B and 70C, and the setting position of knob 20A can be determined. Figure 5B Observed from above Figure 5A The two coordinates of the electrostatic capacitance S2 respectively represent the positions of the diagonally arranged columnar parts 70B and 70C, and the center point C of the diagonal positions is calculated, and the center point C is determined as the setting position of the knob 20A. In addition, the coordinates of the two electrostatic capacitances S1 represent the positions of the two fingers F, in other words, the coordinates represent the outline of the knob 20A. Therefore, the size of the knob 20A can be determined based on the coordinates of the electrostatic capacitance S1, or based on the coordinates of the electrostatic capacitance S2 and the coordinates of the electrostatic capacitance S1.

[0063] Figure 6 : is a diagram showing the change / update process of the setting position of the knob involved in the present embodiment. The user sticks the knob on the display using an adhesive or the like (S10). The operation unit determines whether the knob is set based on the size of the electrostatic capacitance, and then detects the position of the columnar parts 70B and 70C of the conductor 70, determines the setting position of the knob based on the detected position, and automatically updates the original setting position based on the determined setting position. Then, the user's knob operation is detected (S30). In this way, it is possible to determine whether the knob is set and the setting position, without the need for the user to rewrite the coordinates of the setting position of the knob to the operation unit when installing the knob as in the prior art ( Figure 3 Step S20).

[0064] [Example]

[0065] Next, the first embodiment of the present invention will be described in detail. Figure 7 1 is a block diagram showing the structure of an input device according to the first embodiment of the present invention. The input device 100 of the present embodiment includes: a capacitive touch panel 110, a knob 120 mounted on the surface of the touch panel 110, a detection controller 130 for detecting the operation of the touch panel 110 or the knob 120, a display 200, and an image controller 210.

[0066] The touch panel 110 includes, for example, a plurality of detection sensors formed at positions where a plurality of electrode lines on the X side and the Y side intersect, and the detection sensors detect changes in electrostatic capacitance when a user's finger or hand approaches or contacts the touch panel 110. The touch panel 110 is mounted on the display 200, and provides a user input interface for inputting buttons to icons and the like displayed on the display 200. The image controller 210 generates images of icons and the like to be displayed on the display 200, and is mounted, for example, in a vehicle-mounted device.

[0067] The knob 120 and the touch panel 110 together provide a user input interface. The physical operation information when the user operates the knob 120 is expressed as a change in the electrostatic capacitance of the touch panel 110, and the change in the electrostatic capacitance is detected. Figure 4 The knob 20A shown has the same structure and is composed of a donut-shaped rotary operation element (rotary encoder). The knob 120 can be mounted at any position on the touch panel 110, for example, by attaching the bottom of the knob 120 to the surface of the touch panel 110 with a double-sided adhesive.

[0068] The knob 120 includes a cylindrical housing made of an insulating material such as plastic, and a conductor 70 is provided inside or near the surface of the housing to rotate with the rotation of the knob 120. The shape and material of the conductor 70 are not particularly limited, and here, the conductor 70 includes a thin plate-shaped circular portion 70A and a pair of columnar portions 70B, 70B extending from the diagonal portions of the circular portion 70A in the plumb direction, and when the knob 120 is rotated, the conductor 70 also rotates and moves together.

[0069] The columnar portions 70B and 70C are capacitively coupled to the detection sensor of the touch panel 110 , and when the user pinches the knob 120 with the finger F or rotates the knob 120 , the positions of the columnar portions 70B and 70C are detected by the detection controller 130 .

[0070] The detection controller 130 is electrically connected to the touch panel 110, controls the overall operation of the touch panel 110, and detects the user's operation input to the touch panel 110 or the knob 120. The detection controller 130 is composed of hardware and / or software, for example, by using a controller including ROM / RAM, and software for controlling the touch panel 110 is installed in the ROM / RAM.

[0071] The detection controller 130 is as follows Figure 7 As shown in FIG. 1 , the touch panel 110 includes a driving / measuring unit 132, an operation detecting unit 134, and a setting position determining unit 136. The driving / measuring unit 132 drives a plurality of electrode lines on the X side and / or the Y side of the touch panel 110, and measures the electrostatic capacitance of each detection sensor of the driven electrode line. The operation detecting unit 134 detects the operation of the touch panel 110 or the operation of the knob 120 based on the electrostatic capacitance measured by the driving / measuring unit 132.

[0072] For example, when the finger F of the user approaches or contacts the touch panel 110 , the operation detection unit 134 detects the touch position on the touch panel 110 based on a change in the electrostatic capacitance of the corresponding detection sensor.

[0073] In addition, if the user's finger F touches the knob 120, the operation detection unit 134 detects the touch on the knob based on the change in the electrostatic capacitance. As the touch on the knob 120 has a small electrostatic capacitance, it is detected separately from the touch on the display. The detection of the touch on the knob 120 can be used to determine whether the knob 120 is mounted on the touch panel 110.

[0074] Furthermore, when the user's finger F touches the knob 120, the operation detection unit 134 detects the position of the conductor based on the change in electrostatic capacitance on the conductive path of the conductor 70 passing through the knob 120. In this way, the operation detection unit 134 detects the touch or the touched position of the touch panel 110, the touch or the touched position of the knob 120, the position of the conductor of the knob 120, and the like based on the change in electrostatic capacitance.

[0075] The setting position determination unit 136 determines the setting position of the knob based on the detection result of the operation detection unit 134. If the operation detection unit 134 detects that the knob 120 is mounted on the touch panel 110 (that is, the finger F touching the knob 120 is detected), the setting position determination unit 136 then calculates the center point based on the detected positions of the pair of columnar portions 70B and 70C of the conductor 70, and determines the calculated center point as the setting position of the knob 120. If the setting position determination unit 136 determines the setting position of the knob 120, the coordinates of the setting position are written to the operation unit (for example, the memory or register of the operation detection unit 134). In this way, it is possible to detect the operation of the mounted knob. The mounted knob may be any of a newly installed knob, a later-attached knob, or a replacement knob.

[0076] Next, Figure 8 The following is a flow of determining the setting position of the knob according to the present embodiment. First, the setting position determination unit 136 determines whether a touch is detected by the operation detection unit 134 (S100). Specifically, a touch is detected when the electrostatic capacitance is equal to or greater than a threshold value.

[0077] Next, the position determination unit 136 is set to determine whether the detection value is within the threshold value of the touch via the knob (S110). Generally speaking, the electrostatic capacitance detected when the knob 120 is pinched with a finger is smaller than when the touch panel is directly touched with a finger. This is because various knob components (fixed parts, adhesives, etc.) are interposed between the finger F and the touch panel 110. Therefore, by setting a threshold value corresponding to the detection value of the electrostatic capacitance when passing through the knob 120, it is determined that the knob is mounted on the touch panel 110.

[0078] Next, when the setting position determination unit 136 determines that the touch is through the knob, it determines whether the detection points are more than two points (S120). In other words, it determines whether the positions of the two columnar components 70B and 70C of the conductor 70 are detected. When it is determined that the detection points are more than two points, the setting position determination unit 136 calculates the size of the knob and the center point of the coordinates based on the coordinate positions of the detection points (S130). The setting position determination unit 136 determines the calculated center point as the setting position of the knob, and writes the setting position to the operation unit (for example, the operation detection unit 134 or other operation processing unit).

[0079] When the knob setting position is written, the operation of the knob 120 is detected, and the image controller 210 updates the GUI etc. according to the knob operation etc. (S140). For example, the operation amount is determined according to the rotation angle (rotational movement amount of the columnar portion of the conductor) when the knob 120 is rotated. Fig. 9 An example of an algorithm for detecting the rotation angle of a knob is shown. Fig. 9 As shown in (A), the coordinates of the center point of the knob are set to the 0 degree position as the reference. Here, an example of setting is shown in which the right side is set to 0 degrees and the angle increases counterclockwise. Fig. 9 As shown in (B), the position angle of the conductor built into the knob is calculated. For example, if there is a conductor between 0° and 90°, it is detected as 45°. Fig. 9 As shown in (C), when the position of the conductor moves from 45° to 90°, the rotation amount is judged to be 45°.

[0080] On the other hand, if it is not determined in step S110 that the touch is via the knob, and if it is not determined in step S120 that the detection points are more than 2 points, the process returns to the beginning, and the presence or absence of touch is determined each time. If the finger is removed (touch is not detected), the process ends.

[0081] As described above, according to this embodiment, the setting position of the knob is determined based on the detection point or detection position of the conductor when the knob is operated, and the determined setting position is provided to the operation unit that detects the operation of the knob. Therefore, there is no need for the user to write the setting position of the knob to the operation unit every time the knob is replaced or set as in the prior art. This can reduce the trouble of replacing the knob or setting the knob and improve the convenience of the knob with excellent customization.

[0082] Next, the second embodiment of the present invention will be described. In the first embodiment, the pair of columnar portions 70B and 70C of the conductor 70 are arranged diagonally to detect the positions of the columnar portions 70B and 70C. However, in the second embodiment, Fig.10As shown in (A), the two columnar parts 70D and 70E of the conductor 70 of the knob 120A are not arranged diagonally, but are arranged at a certain angle interval (for example, 90°) and the positions of the columnar parts 70D and 70E are detected. Fig.10 In another example of (B), the conductor 70 includes one columnar portion 70F, and the position of the columnar portion 70F is detected.

[0083] In the second embodiment, for example, a calibration mode for determining the setting position of a knob is installed. In this calibration mode, after the knob is set, a rotation operation is performed to rotate the knob one circle, and the setting position or size of the knob is determined based on the detected position of the conductor obtained by the rotation operation.

[0084] Fig.11 FIG. 2 is a diagram for explaining a method for determining the setting position of the knob in the calibration mode. Fig.11 As shown in (A), Fig.10 The knob 120A shown in (A) is mounted on the protective glass. When the knob 120A is pinched with fingers, the positions of the two columnar parts 70D and 70E are detected.

[0085] Next, if Fig.11 As shown in (B), in the calibration mode, the knob 120A is rotated by a finger. When the knob 120A is rotated, the columnar parts 70D and 70E rotate and move. During the rotation of the knob 120, the driving / measuring unit 132 drives / measures the electrode wire in a certain cycle, and detects the positions of the columnar parts 70D and 70E in each cycle.

[0086] Next, if Fig.11 As shown in (C), the setting position determination unit 136 calculates the center point C based on the circular trajectory shape formed by the rotational movement of the detection points, namely the columnar parts 70D and 70E, and determines it as the setting position of the knob.

[0087] As described above, according to this embodiment, even if the columnar portion of the conductor is not necessarily located at the diagonal position, the setting position of the knob can be determined. Fig.10 In the case of the knob 120B of the conductor having one columnar portion 70F as shown in (B), the knob 120B can be rotated to determine the position of the knob in the same manner based on the movement trajectory of the columnar portion 70F. Furthermore, in the above example, the knob is rotated once, but the rotation angle of the knob does not necessarily have to be one circle, and may be half a circle, as long as the center point can be calculated. Furthermore, the number of columnar portions of the conductor is not limited to one or two, and may be three or more.
