Summary of the Invention

Problems to be Solved by the Invention

[0004] In a display device that performs capacitive touch operations, a user interface (hereinafter referred to as a three-dimensional UI) has been proposed in which the touch position is tactilely recognized by providing an uneven shape on the cover glass, and the touch position can be understood without looking.

[0005] FIG. 1(A) is an example of an operation of a conventional flat touch panel. The user U visually recognizes the operation icon 12 displayed on the display 10 and inputs by performing a touch operation on the position of the operation icon 12 (the example in the figure is a musical note).

[0006] Figure 1(B) shows an example of operation of a touch panel with a three-dimensional UI, and Figure 1(C) is a schematic cross-sectional view of the three-dimensional UI. A transparent cover lens 26 with an uneven surface is attached to the touch panel 24, and the display 20 displays operation icons 22 in a position that overlaps with the cover lens 26. User U performs input by touching the cover glass 26 with their finger. A highly sensitive electrostatic sensor is used for touch detection, which can detect the capacitance (distance) of the finger even when it is far from the sensor, making it possible to determine whether or not a touch has been made even through the thick cover lens 26. This makes it possible to reduce touch errors (operation errors) in situations where it is difficult to pay attention to the in-vehicle display while driving.

[0007] As mentioned above, a 3D UI requires the touch panel to mimic the shapes of various physical switches (buttons, knobs, sliders, etc.) present in the vehicle interior and to detect their operation, thus requiring support for a wide variety of operation gestures.

[0008] One example is the type of in-vehicle switch 30, as shown in Figure 2(A), which is pulled upwards (or lifted) at the end, similar to a power window switch. When a touch panel is designed to mimic the shape of such a pull-type switch 30, as shown in Figure 2(B), it is necessary to attach a cantilevered cover glass 60 (or similar material such as resin) to the surface of the touch panel 50 mounted on the display 40, which provides a grip for the finger.

[0009] However, because there is a distance between the capacitance-detecting sensor and the finger's touch position, and because the finger is lifted in the opposite direction to the sensor (arrow direction), it is difficult to accurately detect the finger pulling operation due to the configuration of the cover glass 60.

[0010] As a possible solution, one could consider mounting a touch sensor 64 for detecting capacitance on the back surface of the cantilevered operating section 62 of the cover glass 60, as shown in Figure 2(C). However, this is not practical because it would increase the number of parts in the touch sensor 64 and complicate the structure.

[0011] Therefore, a structure and method are needed that can more accurately detect pulling operations while maintaining a configuration that mimics the pull-type switch 30 shown in Figure 2(B).

[0012] The present invention aims to solve these conventional problems and to provide an input display device that can detect pulling operations on a three-dimensional operating part. [Means for solving the problem]

[0013] The input display device according to the present invention comprises a display for displaying an image, a capacitive touch panel mounted on the display and having at least one three-dimensional operating part on its surface, and a detection means for detecting operations on the touch panel, wherein the three-dimensional operating part has a pull portion that mimics the shape of a pull-type switch, and the detection means determines whether or not a pull operation is performed by detecting a change in capacitance in accordance with a change in the distance from the finger touching the pull portion to the touch panel.

[0014] In one embodiment, the operating unit is attached to the touch panel so as to be detachable via an elastic member. In one embodiment, the elastic member is provided between the bottom surface of the operating unit and a fixed part supporting the display. In one embodiment, the operating unit has a pulling portion and a bottom surface portion located below the pulling portion, and the elastic member is provided between the pulling portion and the bottom surface portion. In one embodiment, the operating unit has a pulling portion and a bottom surface portion located below the pulling portion, and the elastic member is provided between the pulling portion and a fixed part supporting the display. In one embodiment, the pulling portion is composed of a member that is elastically deformable in the pulling direction. In one embodiment, the detection means determines that a pulling operation has been performed if the decrease in capacitance of the pulling portion is greater than or equal to a threshold. In one embodiment, the detection means determines that a pressing operation has been performed if the increase in capacitance of the pulling portion is greater than or equal to a threshold. In one embodiment, the detection means determines whether or not a pulling operation has been performed by detecting a change in capacitance due to a change in the shape of a finger touching the pulling portion. In one embodiment, the input display device further includes display means for displaying icons representing input operations at positions on the display corresponding to the operation section. [Effects of the Invention]

[0015] According to the present invention, the presence or absence of a pulling operation is determined by detecting a change in capacitance corresponding to a change in the distance from the finger touching the pulling part to the touch panel. Therefore, without increasing the number of parts in the touch sensor, it is possible to detect pulling operations more accurately with a simple structure. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0017] Next, embodiments of the present invention will be described. The input display device of the present invention provides an interface between a human and a machine. The input display device of the present invention is not particularly limited, but is applied to, for example, an electronic device equipped with a display with a touch panel. An electronic device equipped with a display with a touch panel is, for example, an in-vehicle device having a navigation function, an audio-visual function, a TV function, and the like.

Example

[0018] Next, embodiments of the present invention will be described in detail with reference to the drawings. Figure 3 is a block diagram showing the configuration of an input display device according to an embodiment of the present invention. The input display device 100 of this embodiment includes a display 110 for displaying images and videos, a capacitive touch panel 120 mounted on the display 110, one or more three-dimensional UI parts (or operation parts) 130 having a three-dimensional shape attached to the surface of the touch panel 120, and a controller 140 that controls the display of images on the display 110 and the detection of touches on the touch panel 110.

[0019] The display 110 is not particularly limited, but includes, for example, a liquid crystal panel or an organic EL panel, and displays image data provided by the controller 140. For example, below the 3D UI section 130, icons representing input operations for the 3D UI section 130 are displayed.

[0020] The touch panel 120 includes, for example, a plurality of detection units (sensors) formed at the intersection of multiple X-side and Y-side electrode lines, and these detection units change capacitance when a user's finger or hand approaches or touches the touch panel 110. The touch panel 120 is mounted on the display 110 and provides an input interface for the user to input icons and the like displayed on the display 110.

[0021] The touch panel 120 further includes one or more three-dimensional UI parts (operating parts) 130 on the surface of the transparent panel. The three-dimensional UI parts 130 have a shape that allows the user to pull them with their fingers, and for example, they have a cantilevered pulling part 134 that pulls (or lifts) the end upward, as shown in Figure 2(B), mimicking the shape of a power window switch as shown in Figure 2(A). The number and size of the three-dimensional UI parts 130 are not particularly limited, but the three-dimensional UI parts 130 are configured such that the capacitance at the position changes when the user's hand or fingers pull or lift the three-dimensional UI part 130.

[0022] Figure 3 shows an example in which four three-dimensional UI units 130 are mounted below the touch panel 120. The three-dimensional UI units 130 are made of transparent materials such as acrylic, polycarbonate, or glass, and icons representing user input operations are displayed at positions on the display 110 corresponding to the three-dimensional UI units 130. However, the entire three-dimensional UI unit 130 does not need to be transparent; parts that do not interfere with the icons may be opaque. The user visually identifies the icons displayed below the three-dimensional UI unit 130 and performs input by pulling on the three-dimensional UI unit 130.

[0023] Next, an overview of the input display device 100 of this embodiment will be described with reference to Figure 4. Figure 4(A) shows a schematic cross-section of the three-dimensional UI section 130. As shown in the figure, the display 110 is fixed on a product cover (or cover glass, etc.) 170, and a touch panel 120 is mounted on it. The three-dimensional UI section 130 is attached to the surface of the touch panel 120.

[0024] The three-dimensional UI section 130 includes, for example, a base section 132 and a tension section 134 that extends from the base section 132 in a cantilevered manner. The base section 132 is attached to a predetermined position on the touch panel 120 using, for example, double-sided adhesive. The mounting position of the base section 132 and the coordinates indicating the shape of the base section 132 are pre-registered in the controller 140. For example, if the base section 132 is circular, the coordinates of its center and radius are registered, and if the base section 132 is rectangular, the coordinates of the intersection of its diagonals and the coordinates of its corners are registered. The height of the tension section 134 of the three-dimensional UI section 130 is also registered.

[0025] In this embodiment, the 3D UI section 130 detects the change in the distance from the finger U to the detection section (sensor) of the touch panel 120 (hereinafter referred to as the finger distance) when the finger U touches the pulling section 134, thereby enabling the detection of a pulling operation on the pulling section 134.

[0026] As shown in FIG. 4(A), for example, like the operation of a power window switch, when the finger U is hooked on the end of the pulling part 134 and a pulling operation is performed, the change in the finger distance D at which the finger U moves away from the touch sensor is detected to determine the presence or absence of a pulling operation. When the finger distance D increases due to the pulling operation, the value of the capacitance detected by the touch sensor decreases. Therefore, in this embodiment, a detection structure using a cushioning material 180 shown in FIG. 4(B) that makes it easier for a change in the finger distance D to occur when pulled by the finger U, or a pulling detection algorithm that detects the deformation of the finger U during a pulling operation as shown in FIGS. 4(C) and (D) is implemented to realize the detection of a pulling operation.

[0027] For the detection structure using a cushioning material, when the user lifts the pulling part 134 and the finger distance D increases, the shape, material, size, mounting position, etc. of the cushioning material are not particularly limited. In the detection structure shown in FIG. 4(B), two cushioning materials 180 that can be elastically deformed in the vertical direction are attached between both ends of the bottom 132 of the three-dimensional UI part 130 and the product cover 170. For the cushioning material 180, an elastic member such as rubber, spring, sponge, or resin can be used. When the user performs an operation of pulling the pulling part 134 with the finger U, the three-dimensional UI part 130 is slightly lifted upward by the cushioning material 180, and a slight distance L is generated between the bottom 132 and the surface of the touch panel 120. As a result, the finger distance changes from D to D1 (D < D1), and this change brings about a change in capacitance for determining the presence or absence of a pulling operation.

[0028] In the above example, the three-dimensional UI part 130 is made separable from the touch panel 120 in the pulling direction using the cushioning material 180. However, for example, by giving elasticity to the pulling part 134 itself of the three-dimensional UI part 130, the pulling part 134 may be displaced in the pulling direction without using a cushioning material. For example, the width of the cantilever-like base of the pulling part 134 can be narrowed, or the thickness of the base can be thinned to facilitate elastic deformation, or the pulling part 134 can be made of an elastic material.

[0029] Next, a pulling detection algorithm for detecting finger deformation will be described. FIG. 4(C) shows a state where finger U touches the pulling portion 134, and the finger distance at this time is D. When the user hooks and lifts finger U on the pulling portion 134, the shape of the finger is compressed in the pulling direction by the stress. As a result, the finger distance changes from D to D2 (D < D2). This change in finger distance brings about a change in capacitance that can detect the pulling operation, The touch panel 120 has a sensitivity capable of detecting such a change in capacitance.

[0030] Next, the details of the controller 140 will be described. The controller 140 is electrically connected to the display 110 and the touch panel 120, and performs image control of the display 110 and touch control of the touch panel 120. The controller 140 holds data such as the height, shape, position, and video display area of the three-dimensional UI unit 130, performs display area correction processing, touch detection and operation determination (touch coordinate detection, finger distance / capacitance magnitude detection) from the output value of the touch panel 120, and performs processing such as video display / video switching according to it, and is responsible for all processing of the input display device. The processing of the controller 140 is executed by hardware and / or software, and for example, is executed using a microcontroller including an arithmetic processing unit, ROM / RAM, etc.

[0031] As shown in FIG. 3, the controller 140 includes a touch detection unit 150, an operation determination unit 160, and a display control unit 170. The touch detection unit 150 drives a plurality of electrode lines on the X side and / or Y side of the touch panel 120, measures the capacitance of each detection unit of the driven electrode lines, and provides the measurement results to the operation determination unit 160.

[0032] The operation determination unit 160 detects touch operations and pulling operations on the touch panel 120 based on the measurement results of the touch detection unit 150. Here, "touch" includes not only contact between the user's finger and the touch panel 120, but also when the finger approaches within a certain distance of the touch panel 120. For example, when the user's finger touches or approaches the flat surface of the touch panel 120, the operation determination unit 160 determines that a touch operation has occurred based on the change in capacitance of the corresponding detection unit. Similarly, when the user's finger touches or approaches the three-dimensional UI unit 130, the capacitance of the detection unit corresponding to the three-dimensional UI unit 130 changes, and this change in capacitance determines that a touch operation has occurred on the three-dimensional UI unit 130.

[0033] Furthermore, when the operation determination unit 160 detects a touch operation on the 3D UI unit 130, if a change in capacitance occurs at the touch location within a certain period of time, it determines whether or not a pulling operation has occurred based on that change. In other words, as shown in Figures 4(B) and 4(D), if the capacitance changes in accordance with a change in finger distance, and that change is above a certain threshold, it is determined that a pulling operation has occurred on the 3D UI unit 130. When the operation determination unit 160 determines that a touch operation or a pulling operation has occurred, the controller 140 provides the input to other electronic devices or performs display control or other actions in accordance with the input.

[0034] The display control unit 170 displays images or videos on the display 110 and displays icons at corresponding positions on the 3D UI unit 130. The icons can be designed to represent user input operations; for example, an icon representing power window operation is displayed below the 3D UI unit 130. The display control unit 170 also switches the image displayed on the display 120 to a different image when the operation determination unit 160 determines that a touch operation or pull operation has occurred.

[0035] Next, the details of the three-dimensional UI section 130 in this embodiment will be described. First, the method for detecting finger distance in the three-dimensional UI section 130 using cushioning material will be described. In the structure shown in Figure 5(A), cushioning material 180 is placed between the product cover 170 and the bottom surface 132 of the three-dimensional UI section 130. When the pulling section 134 is pulled with a finger U, the cushioning material 180 stretches vertically, causing the bottom surface 132 to separate from the surface of the touch panel 120. This increases the finger distance between the touch panel 120 and the finger U, and decreases the capacitance detected by the touch panel 120. If this change in capacitance is above a threshold, it is determined to be a pulling operation.

[0036] On the other hand, as shown in Figure 5(B), when the end of the pulling portion 134 is pressed in with a finger U, the opposite of the pulling operation, the cushioning material 180 is compressed vertically, the bottom portion 132 comes closer to the surface of the touch panel 120, and the distance between the finger U and the touch panel 120 decreases, so the capacitance detected by the touch panel 120 increases. If this change in capacitance is above a threshold, it is determined to be a pressing operation.

[0037] Furthermore, the cushioning material 180 is attached in an appropriate position so as not to reduce the visibility of the displayed icons or to reduce the structural flexibility of the three-dimensional UI section 130. In the three-dimensional UI section 130 shown in Figure 5(A), the bottom section 132 and the tension section 134 may be integrally molded, or the two may be bonded together with adhesive or double-sided tape. If the bottom section 132 and the tension section 134 are integrally molded or bonded together, it is desirable to install or attach the cushioning material 180 to the outer periphery of the sensor or icon display of the touch panel 120.

[0038] If the cushioning material 180 is transparent, or does not need to be transparent, it may be sandwiched and bonded between the bottom portion 132 and the tension portion 134, as shown in Figure 5(C). In this case, the tension portion 134 changes in the tension direction or the pressing direction via the cushioning material 180, while the bottom portion 132 does not change.

[0039] Furthermore, in the case where the bottom portion 132 and the tension portion 134 of the three-dimensional UI portion 130 are not in direct contact or attached to each other, as shown in Figure 5(D), the cushioning material 180 is attached between the tension portion 134 and the product cover 170 on the side of the bottom portion 132, the touch panel 120, and the display 110. In this case as well, the tension portion 134 changes in the pulling direction or the pressing direction via the cushioning material 180, while the bottom portion 132 does not change.

[0040] Next, a method for detecting finger distance in the three-dimensional UI section 130 without using cushioning material will be described. If the sensor has sufficient accuracy to detect small changes in finger distance (for example, about 2 mm), pulling and pressing operations can be detected even in a structure without cushioning material. Figures 6(A) and (B) show what happens when finger U touches the end of the pulling section 134, and the finger distance from the sensor to the finger is D. Figures 6(C) and (D) show how finger U deforms (collapses) when pulling is performed by hooking finger U onto the end of the pulling section 134, and as finger U deforms by about 2 mm, the finger distance from the sensor to finger U increases to D2 (D2>D).

[0041] Next, Figure 7 shows the flow of the operation determination operation of the operation determination unit 160 when no cushioning material is used. The operation determination unit 160 detects the presence or absence of a finger below the pulling part 134 based on the capacitance measurement result by the touch detection unit 150 (S100). As shown in Figure 8, the position coordinates when the finger U is hooked onto the pulling part 134 (part of arrow H) and the finger distance / capacitance threshold when the finger U is below the pulling part 134 (part of arrow V) are registered in advance in the operation determination unit 160. Note that although only the coordinate range in one direction of arrow H is shown in the figure, the coordinate range indicated by arrow H may be specified as planar coordinates.

[0042] The operation determination unit 160 determines that finger U is below the pulling unit 134 if it detects that finger U is within the position coordinates indicated by arrow H and within the capacitance threshold (within finger distance) indicated by arrow V, based on the measurement results of the touch detection unit 150.

[0043] Next, the operation determination unit 160 determines that a pulling operation has occurred by observing the change in capacitance (S110). Figure 9(A) shows the state before the pulling operation, and Figure 9(B) shows the state during the pulling operation. As shown in Figure 9(B), the pulling operation causes the fingertips to be compressed or crushed, changing the angle of the fingers, which causes the finger distance to change from D in Figure 9(A) to D2. As a result, the capacitance value detected by the sensor of the touch panel 120 decreases. The operation determination unit 160 determines that a pulling operation has occurred by detecting this change in capacitance.

[0044] Next, if the operation determination unit 160 determines that a pulling operation has occurred, it observes the change in capacitance to determine the end of the pulling operation (S120). Figure 10(A) shows the state during the pulling operation, and Figure 10(B) shows the state after the pulling operation has ended. As shown in Figure 10(B), in the operation to end the pulling operation, the finger returns to its original position, the opposite of the pulling operation, and the finger distance changes from D2 in Figure 10(A) to D. As a result, the capacitance value detected by the sensor of the touch panel 120 increases. The operation determination unit 160 determines the end of the pulling operation by detecting this change in capacitance.

[0045] Next, Figure 11 shows the results of verifying the change in capacitance when pulling operations are performed on the 3D UI section without using cushioning material on the actual device. The vertical axis represents the capacitance value, and the horizontal axis represents the number of detected data points. Note that the actual device used for this verification performed capacitance detection at 80 fps (frames per second).

[0046] As shown in the graph, the capacitance value was generally 1100 or higher when the 3D UI part 130 was not being pulled (when the finger distance was small), and the capacitance value decreased to generally 800-600 when the 3D UI part 130 was being pulled (when the finger distance was large). Therefore, by setting the threshold for determining whether or not a pulling operation has occurred to within the range of 800 to 1100 (for example, setting the threshold to 950), it is possible to accurately determine whether or not a pulling operation has occurred.

[0047] Furthermore, Figure 12 shows the results of verifying the change in capacitance when the 3D UI section is pressed on the actual device. The vertical axis represents the capacitance value, and the horizontal axis represents the number of detected data points. Note that the actual device used for this verification performed capacitance detection at 80 fps (frames per second).

[0048] Unlike pulling operations, pressing operations do not cause a change in finger distance due to finger compression. Therefore, it is necessary that the pulling portion 134 of the three-dimensional UI portion 130 itself is made of a flexible material (Figure 12(A)), or that a cushioning material 180 is sandwiched between the three-dimensional UI portion 130 and the product cover (Figure 12(B)) to reduce the finger distance when pressing.

[0049] In this detection example, although the difference in detected values ​​between the presence and absence of a push operation is not as large as during a pull operation, the change in capacitance during a push operation can be read from the graph. For example, by setting a threshold of 325 or higher or lower for the capacitance value, it is possible to determine whether the device is in a pushed-in or unpushed-in state.

[0050] Thus, according to this embodiment, in products with a three-dimensional UI, accurate detection of pulling operations becomes possible with a simple structure without increasing the number of touch sensors. This makes it possible to support the operation gestures of pull-type switches with a three-dimensional UI.
