Description

  The present invention relates to a display control device that moves an image displayed on a touch panel and a display device using the display control device.

  Conventionally, a touch screen image scroll system and method described in Patent Document 1 have been proposed. According to this touch scroll image scroll system, a screen (touch panel surface) is touched with a fingertip (operation body), and the image displayed on the screen is vertically moved by moving (sliding) in a desired direction on the fingertip screen. It can be moved in the direction. When the user's fingertip moves away from the screen, the system senses that the fingertip has left the screen, and then decelerates the vertical movement speed of the image.

  In the touch screen image scroll system described in Patent Document 1 described above, by detecting the amount by which the fingertip is slid, the amount of sliding of the fingertip and the amount of operation on the electronic device side operated thereby are reciprocated in either direction. They are set equal to each other.

  However, from the viewpoint of ergonomic detection, the sliding operation from the upper direction to the lower direction is relatively easy, whereas the sliding operation from the lower direction to the upper direction is difficult to perform due to the structure of the hand. In order to solve such a problem, a touch panel described in Patent Document 2 and an electronic device including the touch panel have been proposed. An electronic device equipped with this touch panel can change the recognition sensitivity in accordance with the sliding direction when performing processing (for example, raising or lowering the volume) according to the sliding direction of the fingertip. More specifically, the detection sensitivity of the slide operation from the downward direction to the upward direction is higher than the detection sensitivity of the slide operation from the upward direction to the downward direction so that the operation is recognized even with a small slide amount (movement amount) of the fingertip. Can be done.

  By the way, the electronic device provided with the touch panel and touch panel of patent document 2 operates the touch panel installed in the perpendicular | vertical state, for example. Therefore, as described above, the detection sensitivity of the slide operation from the downward direction to the upward direction is higher than the detection sensitivity of the slide operation from the upward direction to the downward direction so that the operation can be recognized even with a small slide amount (movement amount) of the fingertip. By increasing the height, it is possible to perform a sliding operation from the downward direction to the upward direction, which is difficult to operate.

  However, since the touch panel and the electronic device including the touch panel described in Patent Document 2 are assumed to be used only when the angle of the touch panel is fixed in a vertical state, for example, the tilt angle of the touch panel ( Even if the (tilt angle) is changed, the detection sensitivity (response sensitivity) of the sliding operation (contact movement operation) in the up and down directions is not changed, so the display screen according to the contact movement operation on the touch panel surface is not changed. The display object cannot be moved accurately.

  The present invention has been made in view of such circumstances, and even when the tilt angle (tilt angle) of the touch panel is changed, the display object on the display screen according to the touch movement operation to the touch panel surface more accurately. A display control apparatus capable of moving the display and a display apparatus using the display control apparatus are provided.

  When the display control device according to the present invention performs movement control of a display object on the display screen in accordance with a contact movement operation by an operating body on the surface of the touch panel in a display unit provided with a touch panel on the display screen, the operation is performed. The movement control of the display object is performed at a first response sensitivity with respect to the contact movement operation in the upward direction on the touch panel surface of the body, and the contact movement operation in the downward direction on the touch panel surface of the operation body is performed. A display control device that controls movement of the display object with a second response sensitivity lower than the first response sensitivity, an inclination angle detection unit that detects an inclination angle of the touch panel surface with respect to the horizontal, and In accordance with the tilt angle detected by the tilt angle detecting means, the difference between the first response sensitivity and the second response sensitivity increases as the tilt angle approaches vertical. Configuration and composed with a response sensitivity control means for controlling the response sensitivity to contact movement operation of the operating member in the touch panel surface as.

  According to such a configuration, when the movement control of the display object on the display screen is performed according to the contact movement operation by the operation body on the touch panel surface in the display unit provided with the touch panel on the display screen, the touch panel surface of the operation body The movement of the display object is controlled with the first response sensitivity with respect to the upward contact movement operation on the touch panel, and from the first response sensitivity with respect to the downward contact movement operation on the touch panel surface of the operating body. When performing the movement control of the display object with the low second response sensitivity, the tilt angle detection unit detects the tilt angle with respect to the horizontal surface of the touch panel surface, and the response sensitivity control unit determines the tilt angle according to the detected tilt angle. Because the response sensitivity to the touch movement operation of the operating body on the touch panel surface is controlled so that the difference between the first response sensitivity and the second response sensitivity becomes larger as the angle becomes closer to the vertical. As the inclination angle to the horizontal of the touch panel surface approaches if brought close to the vertical direction, the contact movement operation in the upward direction becomes possible to operations on the moving distance of the small operating body than the contact movement operation in the downward direction.

  The display control device according to the present invention is configured such that the response sensitivity control means controls the first response sensitivity and the second response sensitivity to the same response sensitivity when the touch panel surface is in a horizontal state. can do.

  According to such a configuration, when the touch panel surface is in a horizontal state, the first response sensitivity and the second response sensitivity are controlled to the same response sensitivity by the response sensitivity control means. Since the ease of the contact movement operation and the downward contact movement operation is not ergonomically different, the operation on the touch panel can be performed more accurately.

  In the display control apparatus according to the present invention, the response sensitivity control unit controls a difference between the first response sensitivity and the second response sensitivity according to the tilt angle detected by the tilt angle detection unit. Later, when the tilt angle of the touch panel surface with respect to the horizontal is different, the difference between the first response sensitivity and the second response sensitivity is controlled again so as to correspond to the different tilt angles. Can do.

  According to such a configuration, after the response sensitivity control unit controls the difference between the first response sensitivity and the second response sensitivity according to the tilt angle detected by the tilt angle detection unit, the horizontal level of the touch panel surface is further increased. Since the difference between the first response sensitivity and the second response sensitivity is again controlled so as to correspond to a different tilt angle even when the tilt angle with respect to is different, the operation on the touch panel always corresponds to the tilt angle. The response sensitivity can be recognized, and the touch panel can be operated more accurately.

  The display control device according to the present invention includes a coordinate detection unit that acquires a coordinate position of the touch panel that is touched by a contact operation by the operating body, and a movement distance of the coordinate position detected by the coordinate detection unit. Contact movement operation determination means for determining whether or not the contact movement is the contact movement operation, and the response sensitivity control means determines whether the operation movement is the contact movement operation based on a movement distance of the coordinate position. The response sensitivity can be changed by changing a threshold value serving as a reference for determining whether or not.

  According to such a configuration, it is determined whether or not the contact operation is a contact movement operation based on the movement distance of the coordinate position of the touch panel touched by the contact operation by the operating body, and a threshold value serving as a reference for the determination is determined. By changing the response sensitivity, the touch panel can be operated more accurately.

  A display device according to the present invention includes a display unit in which a touch panel is provided on a display screen, and the display control device according to any one of claims 1 to 4.

  According to such a configuration, since the display unit having the touch panel on the display screen and the display control device according to any one of claims 1 to 4, the tilt angle of the touch panel is changed. In addition, since the response sensitivity of the contact movement operation in the vertical direction can be changed, the operability of the touch panel and the mobility of the display object on the display screen can be improved.

  According to the display control device of the present invention, when performing movement control of a display object on the display screen according to a contact movement operation by the operation body on the surface of the touch panel in a display unit provided with a touch panel on the display screen, The movement control of the display object is performed with the first response sensitivity with respect to the upward touch movement operation on the touch panel surface of the touch panel, and the first with respect to the downward touch movement operation on the touch panel surface of the operating body. When performing the movement control of the display object with the second response sensitivity lower than the response sensitivity, the tilt angle detection unit detects the tilt angle with respect to the horizontal surface of the touch panel surface, and the response sensitivity control unit according to the detected tilt angle The response sensitivity to the touch movement operation of the operating body on the touch panel surface is increased so that the difference between the first response sensitivity and the second response sensitivity becomes larger as the tilt angle becomes closer to the vertical. Therefore, as the tilt angle of the touch panel surface with respect to the horizontal gets closer to the vertical direction, the touch movement operation in the upward direction can be operated with the movement distance of the operating body less than the touch movement operation in the downward direction. Therefore, even when the inclination angle of the touch panel is changed, it is possible to move the display object on the display screen in accordance with the touch movement operation to the touch panel surface more accurately.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of an in-vehicle device including a display control device according to the first embodiment.

  In FIG. 1, an in-vehicle device 100 (display device) has a processing unit 11 constituted by a computer unit (including a CPU). Connected to the processing unit 11 is a display unit configured by a display screen 13 capable of displaying images and the like provided in the passenger compartment and a touch panel 12 provided on the upper surface of the display screen 13 and capable of various operations. The processing unit 11 is connected to an AV unit 17 capable of reproducing music and video from a disk medium such as a CD / DVD and a navigation unit 18 for performing vehicle navigation processing. Further, the processing unit 11 includes a storage unit 14 (for example, HDD) in which various types of information (for example, map information, facility information, music information, etc.) used by the AV unit 17 and the navigation unit 18 are stored, and a vehicle. An output circuit 15 for supplying an audio signal to a speaker 16 provided in the room is connected. The processing unit 11 is connected to an inclination angle detection sensor 19 for detecting an inclination angle with respect to the horizontal surface of the touch panel 12 constituting the display unit.

  In addition, the processing unit 11 constitutes a display control device together with a display unit in which the touch screen 12 is provided on the display screen 13. Since the touch panel 12 has high transparency, an image (display object) displayed on the display screen 13 through the touch panel 12 can be visually recognized. Furthermore, the touch panel 12 is a resistive film type touch panel. For example, when the surface of the touch panel 12 is traced or repelled (performs a contact movement operation), a voltage signal corresponding to the position coordinates of the contact point is output. It has come to be. Based on this signal, the coordinates of the contact point are obtained.

  In addition, the touch panel 12 has a response sensitivity setting function for setting a response sensitivity to a touch movement operation on the surface of the touch panel 12 in each of the upper and lower directions when the touch panel 12 is operated. Specifically, the touch panel 12 has a direction in which it is easy to operate the fingertip (operation body) according to a tilt angle (tilt angle) with respect to the horizontal of the touch panel 12 set by a response sensitivity control function of the processing unit 11 described later. The lower threshold (for example, the coordinate value for 10 dots) to set a low response sensitivity when the operation is repelled, and the direction in which the fingertip is difficult to operate (upward), or An upward threshold value (for example, coordinate values for 5 dots) that sets a high response sensitivity when a repelling operation is performed can be set to be output.

  In addition, the touch panel 12 includes a contact detection function for detecting that the fingertip (operation body) has touched the touch panel 12 and a coordinate detection function for determining which position on the touch panel 12 the fingertip has touched. ing. As a result, the detected coordinate position due to the touch on the touch panel 12 is sequentially acquired, and the direction in which the coordinate value changes is analyzed, so that the user's fingertip (operating body) can move either upward or downward with respect to the touch panel 12. It is possible to determine whether the contact movement operation is performed in the direction.

  The processing unit 11 can change the response sensitivity of the touch panel 12 according to a predetermined condition (for example, the tilt angle of the touch panel 12 detected by the tilt angle detection sensor 19). have.

  For example, a display control process of a screen (display object) displayed on the display screen 13 is performed by the processing unit 11 and the display unit in which the touch panel 12 is provided on the display screen 13 having the above functions.

  FIG. 2 is a flowchart showing a display control processing procedure by the display unit and the processing unit 11. Hereinafter, it demonstrates according to a flowchart.

  In FIG. 2, the processing unit 11 causes the tilt angle detection sensor 19 to detect the tilt angle θ that is the tilt angle of the surface of the touch panel 12 with respect to the horizontal (S11). Then, the processing unit 11 determines which angle the tilt angle θ detected in step S11 is from 0 ° to 90 ° (S12, S13, S14). At this time, for example, as shown in FIG. 3A, when the touch panel 12 and the display screen 13 provided in the in-vehicle device 100 are assembled in a vertical state with respect to the in-vehicle device body, the processing unit 11 The tilt angle θ1 is in the range of 60 ° <θ1 ≦ 90 ° (YES in S14), and the upper threshold is set to z dots and the lower threshold is set to k dots (S17). Specifically, since the tilt angle θ1 of the surface of the touch panel 12 is approximately 90 °, the contact movement operation to the touch panel 12 with respect to the upward direction is difficult to perform compared to the contact movement operation with respect to the downward direction. The difference between the upward threshold value z and the downward threshold value k is set to the maximum within the setting range. For example, the processing unit 11 sets the difference between the upper threshold value z and the lower threshold value k to 5 dots.

  On the other hand, as shown in FIG. 3B, when the touch panel 12 and the display screen 13 provided in the in-vehicle device 100 are connected in a tilted state with respect to the in-vehicle device body, the processing unit 11 is tilted. Assuming that the angle θ2 is in the range of 30 ° ≦ θ2 ≦ 60 ° (YES in S13), the upper threshold value is set to y dots and the lower threshold value is set to k dots (S16). Specifically, since the tilt angle θ2 of the surface of the touch panel 12 is approximately 50 °, the contact movement operation to the touch panel 12 with respect to the upward direction is somewhat difficult to perform compared to the contact movement operation with respect to the downward direction. The difference between the upper threshold y and the lower threshold k is set to a medium value within the setting range. For example, the processing unit 11 sets the difference between the upper threshold y and the lower threshold k to 3 dots.

  As shown in FIG. 3C, when the touch panel 12 and the display screen 13 provided in the in-vehicle device 100 are connected in a horizontal state with respect to the in-vehicle device body, the processing unit 11 has a tilt angle. Assuming that θ3 is in the range of 0 ° ≦ θ3 <30 ° (YES in S12), the upward threshold is set to x dots and the downward threshold is set to k dots (S15). Specifically, since the tilt angle θ3 of the surface of the touch panel 12 is approximately 0 °, the contact movement operation to the touch panel 12 with respect to the upper direction and the contact movement operation with respect to the lower direction have the same degree of ease of operation. The difference between the upper threshold value x and the lower threshold value k is set to the minimum within the setting range. For example, the processing unit 11 sets the difference between the upper threshold value x and the lower threshold value k to 0 dots, that is, the same value.

  Note that when the tilt angle θ3 is in the range of 0 ° ≦ θ3 <30 °, the difference between the upper threshold value x and the lower threshold value k is set to the same value, but the touch panel 12 and the display screen 13 are When the user is in the horizontal state, no operation is performed by the user. Therefore, even if the user's fingertip touches, the display object displayed on the display screen 13 may be controlled to a value that does not move.

  As described above, after the upper threshold value and the lower threshold value are set in steps S15 to S17, the processing unit 11 determines whether or not the tilt angle θ detected by the tilt angle detection sensor 19 is changed. (S18). Accordingly, when it is determined that the tilt angle θ has been changed (YES in S18), the processing unit 11 repeats the processing from steps S11 to S17 again. On the other hand, when it is determined that the tilt angle θ has not been changed (NO in S18), the processing unit 11 causes the touch panel 12 to determine whether or not the fingertip (operation body) has touched the touch panel 12 (S19: contact). Detection means). Accordingly, when it is determined that the operating tool is not in contact with the touch panel 12 (NO in S19), the processing unit 11 returns to the process of step S18 again and continues the process. On the other hand, when it is determined that the fingertip (operation body) has touched the touch panel 12 (YES in S19), the processing unit 11 causes the touch panel 12 to acquire the coordinate value of the touch panel 12 touched by the operation (S20). : Coordinate detection means).

  Then, the processing unit 11 sequentially acquires the detected coordinate position by the touch operation on the touch panel 12, and analyzes the direction in which the coordinate value changes, thereby determining whether the operation is a contact movement operation (a tracing operation and a flip operation). It is determined whether or not (S21). Accordingly, when it is determined that the operation on the touch panel 12 by the fingertip is not a tracing operation (contact movement operation) (NO in S21), the processing unit 11 returns to the process of step S19 again and repeats the subsequent processes. . On the other hand, when it is determined that the operation on the touch panel 12 by the fingertip is a tracing operation (YES in S21), the processing unit 11 performs a tracing operation (upward) with respect to the touch panel 12 by the user's fingertip (operation body) ( It is determined whether or not a contact movement operation has been performed (S22).

  As a result, as shown in FIG. 4, when it is determined that the drag operation has been performed on the touch panel 12 (YES in S <b> 22), the processing unit 11 is set in steps S <b> 15 to S <b> 17. It is determined whether or not the tracing operation has been performed more than the direction threshold (S23). On the other hand, as shown in FIG. 5, when it is determined that the drag operation is not performed on the touch panel 12 (that is, the drag operation is performed downward) (NO in S22), The unit 11 determines whether or not the drag operation has been performed for the downward threshold or more set in steps S15 to S17 (S24). As a result, when the tracing operation is performed exceeding the threshold value set in each of the vertical directions (YES in S23 and YES in S24), the processing unit 11 sends an operation signal corresponding to the tracing operation (contact movement operation). The image is output to the display screen 13 and the image displayed on the display screen 13 is scrolled (the display object is moved) (S25).

  Then, the processing unit 11 determines whether or not the operation on the touch panel 12 has been completed (S26). As a result, when it is determined that the operation on the touch panel 12 has ended (YES in S26), the display control process is ended (END). On the other hand, it is determined that the operation on the touch panel 12 has not been completed (NO in S26) and that the drag operation has not been performed exceeding the thresholds set in the vertical directions (NO in S23 and NO in S24). When this happens, the processing unit 11 returns to step S19 and repeats the subsequent processing.

  As shown in FIG. 6, whether or not the processing unit 11 has moved in either the upward or downward direction even when the fingertip contact movement operation is diagonally downward to the right. Is determined (S22). Therefore, for example, even when the contact movement distance of the fingertip (operation body) exceeds a predetermined distance for determining that it is a contact movement operation, it is predetermined in either the downward direction or the upward direction. When the touch movement of the fingertip of the distance is not performed, the image displayed on the display screen 13 is not moved.

  In the vehicle-mounted device 100 including the display device according to the first embodiment of the present invention as described above, the user's fingertip on the surface of the touch panel 12 in the display unit in which the processing unit 11 is provided with the touch panel 12 on the display screen 13. When the movement control of the display object on the display screen 13 is performed in accordance with the contact movement operation (tracing operation, flip operation) by the (operation body), the inclination angle with respect to the horizontal of the surface of the touch panel 12 detected by the inclination angle detection sensor 19 is set. Correspondingly, an upward threshold (first response sensitivity) set for an upward tracing operation on the surface of the touch panel 12 of the fingertip, and a downward direction set for a downward tracing operation The difference from the threshold value (second response sensitivity) is controlled so as to increase as the inclination angle of the surface of the touch panel 12 approaches the vertical direction. That. Therefore, as the tilt angle of the surface of the touch panel 12 with respect to the horizontal approaches the vertical direction, the contact movement operation in the upward direction can be performed with a smaller fingertip movement distance than the contact movement operation in the downward direction.

  With such a configuration, in the in-vehicle device 100 including the display control device according to the first embodiment of the present invention, even when the tilt angle (tilt angle) of the touch panel 12 is changed, the surface of the touch panel 12 is more accurately detected. The image (displayed object) on the display screen 13 can be moved in response to the drag operation (contact movement operation).

  FIG. 7 shows a smartphone 20 (display device) according to the second embodiment of the present invention. Similar to the vehicle-mounted device 100 according to the first embodiment described above, the processing unit 11 and the display unit having the display screen 13 provided with the touch panel 12 are provided. Also in such a smart phone 20, display control of the display thing displayed on the display screen 13 in the processing unit 11 and the touch panel 12 is possible similarly to the vehicle-mounted device 100.

  The smartphone 20 is also provided with an inclination angle detection sensor 19. As a result, for example, as shown in FIG. 8, the display control process can be performed even for a smaller change when the inclination changes than the inclination of the display unit in the in-vehicle device 100 described above. Specifically, when the smartphone 20 is in the state shown in FIG. 8A, the processing unit 11 sets the upward threshold value set in the upward contact movement operation on the touch panel 12 and the downward contact movement operation. The difference from the downward threshold set in is maximized. From this state, when the smartphone 20 is gradually tilted as shown in FIGS. 8B, 8C, and 8D, the inclination angle of the smartphone 20 with respect to the horizontal of the touch panel 12 is adjusted accordingly. Get smaller. The processing unit 11 reduces the difference between the upper threshold and the lower threshold in accordance with the decrease in the tilt angle.

  By doing in this way, also in the smart phone 20 which concerns on the 2nd Embodiment of this invention, like the vehicle-mounted apparatus 100 which concerns on the 1st Embodiment of this invention, the processing unit 11 provided in the smart phone 20, and The touch panel 12 can more accurately control the image (displayed object) displayed on the display screen 13.

  In addition, the display control apparatus comprised by the processing unit 11 and the display unit (touch panel 12 and display screen 13) which concern on this invention is not limited to the case where it is used for the vehicle equipment 100 or the smart phone 20, but what kind Form may be sufficient.

  As described above, the display control device (the processing unit 11 and the display unit) and the display device (the in-vehicle device 100 or the smartphone 20) using the display control device according to the present invention are in a display unit in which a touch panel is provided on a display screen. When performing the movement control of the display object on the display screen according to the contact movement operation by the operation body on the touch panel surface, the first response sensitivity with respect to the contact movement operation in the upward direction on the touch panel surface of the operation body. When the movement control of the display object is performed and the movement control of the display object is performed with the second response sensitivity lower than the first response sensitivity with respect to the downward contact movement operation on the touch panel surface of the operation body, The angle detection means detects the tilt angle of the touch panel surface with respect to the horizontal, and the response sensitivity control means causes the tilt angle to approach vertical according to the detected tilt angle. Since the response sensitivity to the touch movement operation of the operating body on the touch panel surface is controlled so that the difference between the first response sensitivity and the second response sensitivity becomes large, the tilt angle with respect to the horizontal of the touch panel surface becomes closer to the vertical direction. The display control device for moving the image displayed on the touch panel, which has the effect that the operation for moving the contact in the upward direction can be operated with the movement distance of the operating body less than the operation for moving the contact in the downward direction, and It is useful as a display device used.
