Description

  The present invention relates to an input reception device including a touch panel.

  There is an information device (for example, an in-vehicle navigation device) provided with a touch panel as an input device on a display surface of a display device. In such an input device, a selection item (such as an icon) is displayed on the display screen, and selection of the selection item is received from the user by touching the touch panel. The user looks for the desired selection item while viewing the display screen and touches it. Therefore, the user needs to look at the display screen when operating the touch panel.

  In this regard, there is a technique in which a vibration device is arranged on the touch panel and the touch panel is vibrated when the selection item is touched to notify the user that the selection item is touched (see Patent Document 1). According to this technique, the user can know the position of the selection item by touch even without staring at the display screen.

  By the way, some users prefer an input device that allows fine input operations with few finger movements. In the conventional technique, the user can know the position of the selection item by vibration, but needs to move the position of the finger until the selection item is searched. Therefore, the conventional technique cannot answer the need to perform a fine input operation with few finger movements.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to perform an input operation even with a few finger movements by using a clear feedback by a vibration pattern to the touch panel in an input device equipped with a touch panel.

  FIG. 4 is a functional block diagram of the arithmetic processing unit 1. In addition, description is abbreviate | omitted about the function for performing a navigation process which is basic operation | movement of the vehicle-mounted navigation apparatus 100. FIG.

  As illustrated, the arithmetic processing unit 1 includes a main control unit 101, an input processing unit 102, a touch panel vibration control unit 103, an input content determination unit 104, and a display processing unit 105.

  The main control unit 101 is a central unit that controls each functional unit. For example, an input to the input device 5 is detected via the input processing unit 102, an instruction from the user is analyzed, and each functional unit is controlled so that a process corresponding to the instructed content is executed. In addition, the touch panel vibration control unit 103 is instructed to drive the touch panel vibration device 9 to generate vibration with a predetermined vibration pattern. In addition, it instructs the input content determination unit 104 to determine the input content to the input device 5. Further, data for drawing the display screen is generated, sent to the display processing device 105, and instructed to be displayed on the display 2.

  The input processing unit 102 receives an input signal from the input device 5 such as the touch panel 51 and sends it to the main control unit 101.

  The touch panel vibration control unit 103 controls the vibration operation of the touch panel vibration device 9 in accordance with an instruction from the main control unit 101. The touch panel vibration control unit 103 determines the vibration pattern of the touch panel vibration device 9 using the vibration pattern information 200.

  FIG. 5 is a diagram showing a configuration of touch panel vibration pattern information 200. As illustrated, the touch panel vibration pattern information 200 stores a record 202 to which a code 201 for identifying the input reception screen is assigned for each input reception screen. Each record 202 stores a touch time 204 and a vibration pattern 205 for each touch reception area 203. The touch reception area 203 is an area on the touch panel (or a corresponding area on the screen) that is received as an input when touched. The touch reception area 203 corresponds to a display area for a scroll instruction reception button during map display, a display area for a button for receiving a page turning request, a display area for a volume adjustment button, and the like.

  With reference to the touch panel vibration pattern information 200, the vibration pattern can be determined based on the currently displayed input reception screen, the touched position, and the touch time.

  FIG. 6 shows an example of a vibration pattern. The horizontal axis is time, and the vertical axis is vibration intensity. It is assumed that the touch time is longer in the order of (A1), (A2), and (A3) and in the order of (B1), (B2), and (3), respectively. The vibration pattern 205 stored in the vibration pattern information 200 is, for example, as shown in (A1) to (A3), with the vibration V having a predetermined intensity continuing for a predetermined time as one vibration, the touch time 204 becomes longer. Try to increase the number of times. That is, the longer the touch time 204, the longer the vibration time per unit time. Alternatively, as in (B1) to (B3), the vibration intensity may be increased as the touch time 204 is longer.

  Returning to FIG. The input content determination unit 104 performs a process of determining the input content from a user operation performed on the input device 5 such as the touch panel 51 according to the main control unit 101 and sending the determination result to the main control unit 101. For the determination, the input content determination information 210 is used.

  FIG. 7 is a diagram illustrating a configuration of the input content determination information 210. As illustrated, the input content determination information 210 stores a record 212 to which a code 211 (corresponding to the code 201 in FIG. 5) for identifying the input reception screen is assigned for each input reception screen. . Each record 212 stores a touch time 214 and an input content 215 for each touch reception area 213 (corresponding to the touch reception area 203 in FIG. 5). For example, in the case of a scroll instruction acceptance screen during map display, the input content 215 stores the scroll speed level (high, medium, low) according to the touch time 214. In addition, in the case of a page turning reception screen in which selection items are displayed as a list, the input content 215 stores the number of pages to be turned according to the touch time. In the case of the volume adjustment screen, the increase / decrease of the volume level is stored according to the touch time.

  With reference to the input content determination information 210, the input content can be obtained based on the input reception screen currently displayed, the touched position, and the touch time.

  Returning to FIG. The display processing unit 105 performs processing for displaying a screen on the display 2 according to the main control unit 101.

<Description of operation>
Next, the operation of the in-vehicle navigation device 100 configured as described above will be described.

  First, the case where a scroll instruction is received during map display will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart of the input content determination process in such a case. FIG. 9 is a screen transition diagram.

  The flow in FIG. 8 is started when the map display processing unit 105 displays a map and accepts a scroll instruction (S101).

  The input processing unit 102 monitors whether or not the touch panel 51 has been touched (S102). If there is a touch (Y in S102), the main control unit 101 is notified that a touch has been detected and the touch position.

  The main control unit 101 initializes the elapsed time t to 0 (S103). Then, an elapsed time t after initialization is obtained (S104).

  Next, the main control unit 101 determines whether or not the elapsed time t has exceeded a predetermined threshold (S105). Here, the threshold value is the maximum value of the time stored in the touch time 204 of the vibration pattern information 200. Specifically, the main control unit 101 acquires from the vibration pattern information 200 a record 202 corresponding to an input reception screen currently being displayed (a scroll reception screen during map display). Then, the maximum value of the time stored in the touch time 204 in the touch reception area 203 corresponding to the touch position notified by the input processing unit 102 is obtained from the acquired record data, and is set as a threshold value.

  When the elapsed time t is less than the threshold value (N in S105), the main control unit 101 shifts the process to S107. On the other hand, when the elapsed time t exceeds the threshold (Y in S105), the main control unit 101 initializes the elapsed time t to 0 (S106), and the process proceeds to S107.

  Note that when the elapsed time t exceeds a threshold value (maximum value of the touch time), the reason why the elapsed time t is initialized to 0 is to repeatedly generate a vibration pattern defined by the vibration pattern information 200.

  In step S107, the main control unit 101 instructs the touch panel vibration control unit 103 to determine a vibration pattern and vibrate the touch panel 51.

  In response to this, the touch panel vibration control unit 103 obtains a vibration pattern according to the elapsed time t. Specifically, first, the touch panel vibration control unit 103 acquires, from the vibration pattern information 200, a record 212 corresponding to an input reception screen currently displayed (a scroll instruction reception screen during map display). And the vibration pattern 205 which is the touch time 204 corresponding to the elapsed time t is acquired from the data of the acquired record in the touch reception area 203 corresponding to the touch position. And the touch panel vibration apparatus 9 is controlled so that a vibration generate | occur | produces with the calculated | required vibration pattern. As a result, the touch panel vibration device 9 generates vibration with the vibration pattern obtained by the touch panel vibration control unit 103. Then, the touch panel 51 vibrates.

  Next, the main control unit 101 determines whether or not the touch state continues through the input processing unit 102 (S108). If it continues (Y in S108), the main control unit 101 returns to S104 and continues the process.

  On the other hand, when the user's finger is released and not in the touched state (N in S108), the main control unit 101 instructs the input determination unit 104 to determine the input content of the user.

  In response to this, the input determination processing unit 104 performs a process of determining the input content of the user (S109). Specifically, the input determination processing unit 104 acquires a record corresponding to the currently displayed screen (map) from the input content determination information 210. And the input content 215 which is the touch time 214 corresponding to the elapsed time t is acquired from the acquired record in the touch area 213 corresponding to the touch position. Then, the acquired input content is sent to the main control unit 101.

  In this way, the main control unit 101 acquires the input content of the user and ends the input content determination process.

  The input content determination process has been described above.

  FIG. 9 is a screen transition diagram when a scroll instruction is received during map display.

  A map 310 is displayed on the display screen 300. The touch panel 51 has a predetermined area 315 for receiving a scroll instruction together with the direction of the scroll instruction. Note that an area 315 may be displayed. When the main control unit 101 detects a touch on any of the areas 315, the main control unit 101 determines that a scroll instruction has been issued. The scroll direction is determined based on which area 315 is touched. Further, the input content determination unit 104 determines the instructed scroll speed based on the length of time that the user has been touched.

  FIG. 9 shows a state in which an area 315 for accepting an instruction to scroll the touch panel 51 in the right direction is touched by the user's finger F.

  When the finger F touches the area 315 that receives the scroll instruction, the number of vibrations V per unit time of the touch panel 51 increases as the touch time increases. If the finger is released when the number of times of vibration V is one (non-touch state), the input content determination unit 104 determines that the content of the instruction is to set the scroll speed to “low speed”. Then, the main control unit 101 scrolls the map at “low speed”. On the other hand, when the finger is released when the number of times of vibration is the third time (non-touch state), the input content determination unit 104 determines that the content is an instruction content for setting the scroll speed to “high speed”. Then, the main control unit 101 scrolls and displays the map at “high speed”.

  FIG. 10 is a screen transition diagram when page turning is accepted by the touch panel when the selection items are displayed in a list.

  A list of selection items is displayed on the display screen 300. The touch panel 51 has a region 325 for receiving a page turning instruction together with its direction. On the display screen 300, a page turning button 325a is displayed at a position corresponding to the area 325. The main control unit 101 determines that the page turning instruction has been given when the area 325 is touched. Further, the turning direction is determined depending on which area 325 is touched. Further, the input content determination unit 104 determines the number of pages to be instructed according to the length of the touched time.

  FIG. 10 shows a state in which an area 325 for accepting page turning in the direction in which the page number is larger is touched by the user's finger F. As the touch time becomes longer, the number of vibrations V per unit time of the touch panel 51 increases. When the finger is released when the number of vibrations is the second time (non-touch state), the input content determination unit 104 determines that the number of pages to be turned is two pages. Then, the main control unit 101 acquires and displays a page obtained by adding 2 to the currently displayed page number. On the other hand, when the finger is released when the number of vibrations is the fourth time (non-touch state), the input content determination unit 104 determines that the number of pages to be turned is four pages. Then, the main control unit 101 acquires and displays a page obtained by adding 4 to the currently displayed page number.

  FIG. 11 is a screen transition diagram when volume adjustment is received by the touch panel.

  On the display screen 300, a screen 330 for volume adjustment is displayed. The touch panel 51 has a region 335 for receiving a sound volume adjustment instruction along with its direction (whether it is increased or decreased). On the display screen 300, a volume adjustment acceptance button 335a is displayed at a position corresponding to the area 335.

  The main control unit 101 determines that there is an instruction to adjust the volume when the area 335 is touched. Further, the direction of adjustment is determined based on which area 335 is touched. Further, the input content determination unit 104 determines an instruction for a width to be adjusted (amount of change) based on the length of the touched time.

  FIG. 11 shows a case where an area 335 for receiving an instruction to increase the volume is touched by the user's finger F. As the touch time becomes longer, the number of vibrations V per hour of the touch panel 51 increases.

  If the finger is released at the second vibration frequency (non-touch state), the input content determination unit 104 determines that the instruction is to increase the volume level by two levels. Then, the main control unit 101 increases the current volume level by two levels. On the other hand, when the finger is released when the number of times of vibration is the fourth (non-touch state), the input content determination unit 104 determines that the instruction is to increase the volume level by four levels. Then, the main control unit 101 increases the current volume level by 4 levels.

  The embodiment of the present invention has been described above. According to the embodiment, the vibration pattern of the touch panel is changed according to the touch time, and the input content is determined according to the touched time. The timing for releasing the finger can be determined according to the content to be input. That is, the user can perform a fine input operation at substantially the same position without moving the finger greatly.

  Thereby, a single button can have a plurality of functions. That is, since different input contents can be received with the same button, the number of buttons displayed on the screen can be reduced. It is possible to prevent the screen from being covered with buttons because of the display of buttons that accept fine settings. Moreover, although the place where the user on a touch panel is easy to push is limited, according to the said embodiment, since the number of buttons can be decreased, a button can be provided intensively in the place where a user is easy to push. In addition, since the display space of the buttons can be narrowed, a dedicated space for receiving a touch may be provided in the display screen separately from the space for displaying the map and the content.

  The main control unit 101 can set the selection of the vibration pattern type from the user via the input device 5.

<Modification>
The present invention is not limited to the above embodiment. The above embodiment can be variously modified.

  For example, the input content may be determined based on the vibration pattern when the touch is not touched (or just before that). For example, instead of the input content 215 corresponding to the touch time 214 of the input content determination information 210 shown in FIG. 7, the input content 215 corresponding to the vibration pattern (205 in FIG. 5) is stored. Then, in the process of determining the input content (S109 in FIG. 8), the following is performed. That is, the input content determination unit 104 acquires the record 212 of the input reception screen currently displayed from the input content determination information 210. Then, from the acquired record 212, the input content 215 of the vibration pattern corresponding to the vibration reception pattern 213 corresponding to the touch position and corresponding to the vibration pattern determined in S107 (that is, the previous vibration pattern) is acquired. Then, the acquired input content is sent to the main control unit 101.

  Moreover, you may provide the function which notifies topography by vibration. Specifically, when a map is traced with a finger, a stronger vibration is generated at a higher altitude position. FIG. 12 is a flowchart of vibration processing during map display. This flow starts when a map is displayed (S201). When the input processing unit 102 detects a touch on the touch panel 51 (S202), the main control unit 101 obtains the altitude of the position on the displayed map corresponding to the touch position from the map data. Then, the touch panel vibration control unit 103 is instructed to vibrate the touch panel 51 with a vibration pattern corresponding to the altitude (S203). The touch panel vibration control unit 103 determines a vibration pattern corresponding to the altitude in advance. Then, the vibration pattern is determined from the altitude notified from the main control unit 101, and the touch panel vibration device 9 is controlled (S204). For example, the vibration intensity is increased as the altitude is higher. The main control unit 101 performs the processes of S203 to S204 while the touch state continues (S205).

  FIG. 13 shows a change in vibration intensity when the touch panel 51 is traced with a finger while the map 310 is displayed on the display screen 300. It is assumed that the user's finger traces the touch panel 51 as shown by an arrow as shown in FIG. As shown in FIG. 13B, the vibration intensity changes according to the altitude of the touched position on the map. Note that the touch panel vibration control unit 103 may increase the number of vibration openings (vibration time) per unit time as the altitude is higher. Further, in the case where the vehicle cannot travel, such as the sea or river, the vibration pattern may be changed from the place where the vehicle does not.
