Description

  The present invention relates to an information display device and a touch panel operation method.

  In an in-vehicle navigation device, it is common to provide an interface equipped with a touch panel and operated by touching a screen with a finger. In this interface, a button image is displayed on the screen, and when a finger touches the button image, the button is pressed, and a predetermined operation is performed. When a touch panel is used as the input means, if the buttons displayed on the screen are made smaller than the fingertips or arranged at a narrow interval, the possibility of an operation error increases. For this reason, the number of operation parts such as buttons that can be prepared on one screen is naturally limited.

  As a method for dealing with the above-described limitation, there is a method in which two functions are assigned to one button and the two functions are selectively used according to the length of the button being pressed (Patent Document 1). In this method, the time during which the finger is touching the button is measured, and if the time is less than the predetermined time, the first function is executed. On the other hand, if the finger has been touching the button for a longer time than the predetermined time, the second function is executed. The latter operation of touching a button with a finger for a longer time than a predetermined time is called a long press operation. In order to notify the user that a long press operation has been detected when using the above-described method, a method of making a beep sound when a predetermined time has elapsed since the button was pressed is known.

Have. The disk drive 23 is loaded with a DVD-ROM 24 in which map data is stored.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. The control circuit 11 performs a predetermined route search process based on the map data stored in the DVD-ROM 24. Then, the processing result is displayed on the display monitor 16 as a recommended route.

  The current location detection device 14 is a device that detects the current location of the vehicle. The current location detection device 14 includes a vibration gyro 14a, a vehicle speed sensor 14b, a GPS (Global Positioning System) sensor 14c, and the like. The vibration gyro 14a detects the traveling direction of the vehicle. The vehicle speed sensor 14b detects the vehicle speed. The GPS sensor 14c detects a GPS signal from a GPS satellite. The navigation device 1 determines a map display range, a route search start point, and the like based on the current location of the vehicle detected by the current location detection device 14, and displays the current location on the map.

  The image memory 15 stores image data to be displayed on the display monitor 16. This image data includes road map drawing data and various graphic data, which are appropriately generated based on the map data stored in the DVD-ROM 24. The navigation device 1 can perform map display and the like by using the image data generated in this way.

  The disk drive 23 reads map data from the DVD-ROM 24. The map data includes map display data, route search data, and the like. The map display data and the route search data include road link information and node information stored in the map data. The map display data has map data of a plurality of scales from wide areas to details, and the scale of the display map can be changed according to a user request. The map data may be read from a recording medium other than the DVD-ROM 24, such as a CD-ROM or a hard disk.

  The display monitor 16 provides the user with various information such as a road map near the vehicle position as a screen display based on various information such as map data. The speaker 17 outputs sound for instructing the user to perform various input operations and for guiding the route. The input device 18 has an input switch for a user to set various commands, and is realized by an operation panel, a remote controller, or the like. The user manually operates the input device 18 according to an instruction on the display screen of the display monitor 16 or a voice instruction from the speaker 17 to select a destination and set the destination.

  The touch panel 20 is a transparent touch switch laminated on the surface of the display monitor 16, and an image displayed on the display monitor 16 is displayed through the touch panel 20. The touch panel 20 sends a signal corresponding to the operation position on the touch panel 20 to the touch panel control unit 19. Then, the touch panel control unit 19 calculates the pressed position of the touch panel 20.

  When the display screen of the display monitor 16 is pressed, the touch panel 20 is pressed. Then, a destination is set at the pressed position, or processing defined in the pressed buttons and display menu is executed.

  The radio receiver 21 receives a radio broadcast and outputs an audio signal. The modulation system (AM, FM) and frequency of the received radio broadcast are set by the control circuit 11.

  When the destination is set by the user, the navigation apparatus 1 performs a route calculation from the current location detected by the GPS sensor 14c to the destination based on a predetermined algorithm. The route thus obtained (hereinafter referred to as a recommended route) is displayed on the screen in a manner different from other roads by changing the display form, for example, the display color. Thereby, the user can recognize the recommended route on the map on the screen. In addition, the navigation device 1 instructs the user in the direction of travel using a screen or voice so that the vehicle can travel according to the recommended route, thereby guiding the route of the vehicle.

  Next, touch panel operation in the navigation device 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 2 is a display screen of the display monitor 16 displaying a screen for selecting a radio broadcast. On the upper part of the display screen 30, the modulation method, frequency (31), and frequency change buttons (32, 33) of the radio broadcast being received are displayed. When the button 32 is pressed, the frequency 31 decreases, and when the button 33 is pressed, the frequency 31 increases.

  In the lower part of the display screen 30, four preset buttons (34, 35, 36, 37) for calling a preset frequency are displayed. Below each button is a frequency display (P1, P2, P3, P4) assigned to that button. The preset button can be operated by either a short press or a long press. Short press refers to an operation of pressing a button and finishing the press before a predetermined time has elapsed. Moreover, long press refers to the operation which finishes pressing, after pressing a button more than predetermined time.

  When a predetermined time for determining that the button is long-pressed while the button is pressed, a flash operation is performed on the display screen 30. The flash operation refers to an operation for performing a special display for a short time on the entire display screen. This special display is, for example, a display in which the entire screen is filled with white, or a display in which the display content of the entire screen is negative-positive inverted. By performing the flash operation, the user can recognize that a predetermined time determined to be a long press has elapsed.

  By pressing the preset button for a short time, the frequency assigned to each button is set to the received frequency, and the display content of the frequency display 31 is changed. When the preset button is pressed for a long time, the frequency being received is assigned to the long-pressed preset button, and the display content of the corresponding frequency display (P1, P2, P3, or P4) is changed. The frequency assigned to the preset button is stored in the data storage unit 22.

  The processing when a short press is performed and the processing when a long press is performed are managed with a data structure described below. FIG. 3 is a diagram showing a data structure associating button operations with processing to be executed. Each screen has a list of display components displayed on the screen. Each display component is assigned an event that occurs in the display component and the processing content when the event occurs. In FIG. 3, when the preset button 34 existing on the display screen 30 is short-pressed, the process of switching the frequency being received is performed, and when the long press is performed, the process of changing the preset value is performed. It is shown.

  In addition, although the description about the above long press was performed using the channel selection screen of radio broadcasting, it is natural that it can apply also to another screen.

  Next, specific processing contents for executing the button short pressing process or the long pressing process will be described with reference to the drawings. FIG. 4 is a flowchart for explaining the processing contents for executing the short press processing or long press processing of the button. This process is realized by the control circuit 11 executing a control program recorded in the ROM 12. When the navigation device 1 is in a state of accepting input from the user, this process is continuously executed.

  First, in step S1, it is determined whether or not the button is pressed. If the button has been pressed, an affirmative determination is made in step S1, and the process proceeds to step S2. On the other hand, if a negative determination is made in step S1, the process ends without executing either the short press process or the long press process. In step S2, a timer for measuring the time during which the button is pressed is started. In step S3, it is determined whether or not the value of the measurement time recorded by the timer is greater than the threshold value of the time for which it is determined that the long press is performed. If the timer value is greater than the threshold value, an affirmative determination is made in step S3, and the process proceeds to step S4. On the other hand, if a negative determination is made in step S3, the process proceeds to step S6. In step S4, it is determined whether or not the user has been notified of the long press. If the long press has already been notified, an affirmative determination is made in step S4, and the process proceeds to step S6. On the other hand, if a negative determination is made in step S4, the process proceeds to step S5. In step S5, the screen is flashed to notify the user of a long press. Thereafter, an affirmative determination is made in step S4.

  In step S6, it is determined whether or not the button is being pressed. If the button is pressed, an affirmative determination is made in step S6, and the process returns to step S3. On the other hand, if a negative determination is made in step S6, the process proceeds to step S7. In step S7, a timer for measuring the time during which the button is pressed is stopped. In step S8, as in step S3, it is determined whether or not the time recorded by the timer is greater than the threshold value. If the timer value is greater than the threshold value, an affirmative determination is made in step S8, and the process proceeds to step S9. In step S9, a long press process assigned to the pressed button is executed. On the other hand, if a negative determination is made in step S8, the process proceeds to step S10. In step S10, a short press process assigned to the pressed button is executed. As described above, the button short press process or the long press process is executed.

According to the navigation apparatus according to the first embodiment described above, the following operational effects can be obtained.
(1) Two operations, short press and long press, were introduced for one display component. Thereby, it is possible to allow the user to select more functions with a limited number of display components.

  The navigation device 101 performs a short button pressing process or a long pressing process by a process similar to that of the first embodiment. However, when a long press operation is detected, vibration is generated using the vibration device 25 instead of flashing the screen. The user can recognize that the long press operation has been detected by checking the vibration transmitted to the finger, not the screen change.

  According to the navigation apparatus according to the second embodiment described above, the following functions and effects can be obtained in addition to the functions and effects obtained by the navigation apparatus according to the first embodiment. Instead of flashing the screen, the user is notified that a long press operation has been detected by transmitting vibration to a finger or the like that is pressing the touch panel 20. Thereby, since notification can be performed with respect to tactile sensation instead of sight, it is possible to confirm that a long press operation has been performed even if the user does not pay attention to the display monitor 16.

  The first embodiment and the second embodiment described above are navigation devices including a touch panel. The present invention can be applied not only to a navigation device but also to an arbitrary information display device provided with a touch panel. The third embodiment described in detail below is a mobile communication terminal including a touch panel that notifies a user that a long press operation has been detected by flashing a display screen.

--Third embodiment--
FIG. 5 is a block diagram showing the mobile communication terminal 201 in the present embodiment. Similar to the navigation device 1 in the first embodiment, the mobile communication terminal 201 includes a control circuit 211, a ROM 212, a RAM 213, an image memory 215, a display monitor 216, a speaker 217, an input device 218, a touch panel 220, and a data storage unit 222. Is provided. Furthermore, the mobile communication terminal 201 includes a communication device 226 for communicating with an external network or a communication device.

  In the mobile communication terminal 201 as well, as with the navigation device 1 in the first embodiment, when a button displayed on the display monitor 216 is pressed and held, the display screen is flashed. Thereby, the same effect as the navigation apparatus 1 in the first embodiment can be obtained.

The following modifications are also within the scope of the present invention.
(1) The screen flash in the first embodiment and the vibration in the second embodiment may be performed simultaneously. Thereby, the detection of the long press operation can be notified to both the visual sense and the tactile sense.
(2) The user may be notified that the long press operation has been detected by changing the color of the button. For example, the button is displayed in red while the predetermined time has not elapsed, and the button is displayed in blue after the predetermined time has elapsed. Further, the background color of the screen may be changed instead of the button color.

  As long as the characteristics of the present invention are not impaired, the present invention is not limited to the above-described embodiments, and other forms conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention. .

  In addition, the correspondence between each component of the navigation device in the embodiment described above and each component of the claims is as follows. The display monitor 16 corresponds to a display monitor, the ROM 12 corresponds to a storage unit, and the control circuit 11 corresponds to a control unit.
