Display image control means 45.

  When receiving information from the input detection unit 3 that the two positions are touched by the user, the control unit 4 executes predetermined event processing by the event processing execution unit 42. The content of the event processing is determined by a combination of the two contact position information detected by the input detection unit 3. Even if the contact position information of only one place is received, the control unit 4 does not execute any event processing. Moreover, even if three or more contact position information is received, the control part 4 does not perform any event processing.

  FIG. 2 shows colors (color A, color B, and color C in the illustrated example) used for displaying labels, buttons, and selection item names. Use colors that make the visual difference clear to the user. For example, the color A is “red”, the color B is “blue”, and the color C is “yellow”.

  FIG. 3 shows an example of a conventional touch panel input device, in which both sides of selection input are displayed on the display panel unit 5 which is a small screen. Nine items from the selection item 1 label L1 to the selection item 9 label L9 are displayed. From the selection item 1 label L1 to the selection item 9 label L9 displayed on the touch panel input device 1, the user selects one label of the item that the user wants to select.

  The input detection unit 3 detects the position of the screen selected and input by the user, and event processing corresponding to the item selected and input is executed by the control unit 4. When selecting “selection item 5” that can be selected by the user, the portion of the selection item 5 label L5 is touched with a finger. However, the display position of the selection item 5 label L5 adjacent between the selection item 4 label L4 and the selection item 6 label L6 due to vibration, trembling of the hand, optical illusion, perspective error, etc., is precisely touched. difficult.

  FIG. 4 is a selection input screen in which the same nine selectable items as in FIG. 3 are displayed on the display panel unit 5 by the touch panel input device 1 of the first embodiment. The A button 6 is displayed in color A, the B button 7 is displayed in color B, and the C button 8 is displayed in color C. The selection item 123 label L10 includes labels (selection item 1 label L1 to selection item 3 label L3) displaying “selection item 1”, “selection item 2”, and “selection item 3” that can be selected by the user. Selectable label. The selection item 456 label L11 includes labels (selection item 4 label L4 to selection item 6 label L6) displaying “selection item 4”, “selection item 5”, and “selection item 6” that can be selected by the user. Selectable label. The selection item 789 label L12 includes labels (selection item 7 label L7 to selection item 9 label L9) displaying “selection item 7”, “selection item 8”, and “selection item 9” that can be selected by the user. Selectable label. The selected item 1 label L1, the selected item 4 label L4, and the selected item 7 label L7 are displayed in the same color A as the A button 6, and the selected item 2 label L2, the selected item 5 label L5, and the selected item 8 label L8 are B buttons. 7, the selected item 3 label L 3, the selected item 6 label L 6, and the selected item 9 label L 9 are displayed in the same color C as the C button 8.

  The labels that the user can select and input by touching the touch panel input device 1 are a selection item 123 label L10, a selection item 456 label L11, and a selection item 789 label L12. The total area of the label for the user to touch is about three times the area of each selectable label shown in FIG. The user may touch any one of the desired selection item 123 label L10 to the selection item 789 label L12 while touching any one of the desired A button 6 to C button 8.

  For example, the selection item 2 label L2 is selected simply by touching the B button 7 anywhere on the selection item 123 label label L10. Even if the B button 7 is touched and the selection item 1 label L1 or the selection item 3 label L3 in the selection item 123 label label L10 is accidentally touched, the selection item 2 label L2 is correctly selected.

  For example, if the touch panel input device 1 is configured so that the display of labels other than the selection item 1 label L1, the selection item 4 label L4, and the selection item 7 label L7 disappears when the A button 6 is touched, it is more visually recognized. It becomes easy to understand and operability is improved.

  FIG. 5 is an example in which the selection item names are displayed in text in the colors of the labels used in FIG. 4 instead of the selection item 1 label L1 to the selection item 9 label L9 illustrated in FIG. The total area of the label for the user to touch is about three times the area of each selectable label shown in FIG.

  Even if only one of the A button 6 to C button 8 or the selection item 123 label L10 to the selection item 789 label L12 is touched, the touch panel input device 1 detects the position of the screen selected and input by the user. The control unit 4 does not execute any event processing. In the touch panel input device 1 of the first embodiment, one of the three A buttons 6 to C 8 and one of the three selection items 123 label L10 to one of the selection items 789L12 are in contact with each other in two places. When an event is detected, event processing is executed by a combination of the touched label and button. Even if two labels and two buttons are touched, the touch panel input device 1 detects information on the touched position and state, and the number of touched parts, but the control unit 4 does not execute event processing.

  FIG. 6 is an explanatory diagram illustrating a first stage of a method in which a user selects and inputs using the touch panel input device 1 according to the first embodiment.

  The user confirms each item displayed on the touch panel input device 1. Here, it is assumed that the user wants to select and input “selection item 5”. The user confirms the display color of “selection item 5” displayed in text on the selection item 456 label L11. The display color of “selection item 5” is the same color B as the display color of the B button 7. The user touches the position where the B button 7 is displayed with the finger of the hand H1. Once contacted, the B button 7 remains in contact. If the B button 7 is once released, the B button 7 is contacted again and remains in contact. Even if a label or button other than the B button 7 is accidentally touched, if the button or label is released and the B button 7 is touched again, an event that is not intended by the user will not occur.

  FIG. 7 is an explanatory diagram illustrating a second stage of a method in which the user selects and inputs “selection item 5” using the touch panel input device 1 according to the first embodiment.

  The user touches the selection item 456 label L11 while touching the B button 7 as illustrated in FIG. The control unit 4 executes event processing of “selection item 5” by a combination of the button (B button 7) and the label (selection item 456 label L11).

  Since the user touches the selection item 456 label L11 while touching the B button 7, the index finger touching the B button 7 is supported, and the selection item 456 label L11 is touched even if there is a slight vibration. Is not difficult. The label of FIG. 7 is about three times as large as the label illustrated in FIG. 3, so that even if the hand shakes slightly and the hand is out of order, the item to be selected can be selected accurately and easily. it can.

  Even if the selection item 456 label L11 is touched first and the B button 7 is touched as it is, the event processing of “selection item 5” is executed.

  FIG. 8 is a flowchart illustrating an example of processing performed by the touch panel input device 1 according to the first embodiment.

  In step S11, the control unit 4 instructs the display panel unit 5 to display buttons and selection items.

  In step S <b> 12, the display panel unit 5 displays buttons and selection items instructed from the control unit 4. On the other hand, the user confirms the display color of the desired selection item and touches the button having the same display color as that selection item.

  In step S13, the input detection unit 3 detects whether or not the user has touched the button. In step S14, when the input detection unit 3 cannot confirm contact with the button, the process returns to step S13 and waits for the user to touch the button.

  On the other hand, if the input detection unit 3 has confirmed contact with the button in step S14, the input detection unit 3 detects whether the user has touched the label in step S15.

  In step S16, when the input detection unit 3 cannot confirm contact with one button and one label, the process returns to step S13, and when contact with one button and one label can be confirmed, in step S17. The input detection unit 3 detects a contact position on the input panel unit 2 by the user.

  In step S <b> 18, the control unit 4 starts executing predetermined event processing according to the button position and the label position detected by the input detection unit 3.

  In the flowchart illustrated in FIG. 8, the presence / absence of contact with the button is first detected (steps S <b> 13 to S <b> 14), and then the presence / absence of contact with the label is detected (steps S <b> 15 to S <b> 16). The order of processing is not limited to this. First, the presence / absence of contact with the label may be detected (steps S15 to S16), and then the presence / absence of contact with the button (steps S13 to S14) may be detected. You can go.

[Second Embodiment]
In the input detection unit 3 in the second embodiment, the contact position detection unit 31 detects the position of the input panel unit 2 where the user touches the finger and releases the contacted finger, and the contact presence / absence detection unit 32 It is detected whether the input panel unit 2 is touched with a finger and the finger is released.

  In the control unit 4 according to the second embodiment, the contact image detection unit 43 detects which part of the display panel unit 5 corresponds to the part where the user touches and separates the input panel unit 2. The control unit 4 receives the information that the two positions are touched from the input detection unit 3, and executes event processing when receiving information that the finger is separated from the touch panel input device 1 at one of the positions. To do. The content of the event process is determined by a combination of position information in a state where the finger is in contact and position information when the finger is released. Or it determines with the combination of the positional information when a finger | toe is removed simultaneously at two places. Even if the control unit 4 receives the information that the two positions are in contact with each other, the control unit 4 does not execute the event process unless the information received after the reception is received.

  The control unit 4 receives information indicating that one of the three buttons is in contact and information indicating that one of the three labels is in contact, and then releases the button or label. Is received, and each event process is executed. The content of each event process is determined by the combination of the button and the label. In the combination of a button and a button, or a label and a label, the control unit 4 does not execute the event process and enters a selection input waiting state again.

  For example, the selection item 456 label L11 is touched while the B button 7 is touched, and the finger is released from the label. The control unit 4 executes event processing of “selection item 5” by a combination of the B button 7 and the selection item 456 label L11. Even if the selection item 123 label L10 is accidentally contacted while the B button 7 is kept in contact, the event processing of “selection item 2” is not executed unless the finger is removed from the contacted label L10. If the finger that has selected the selection item 123 label L10 is not released from the touch panel input device 1 and is slid to the selection item 456 label L11 as it is, the event processing of “selection item 5” is started.

[Third Embodiment]
As illustrated in FIG. 9, when the control unit 4 in the third embodiment is in contact with the input panel unit 2 by the user in addition to the components of the first embodiment or the second embodiment. In addition, a time measuring means 46 for starting time measurement is provided.

  The control unit 4 calculates the currently selectable items and displays a maximum of five selection item names on the touch panel input device 1 (when operating with each finger of one hand). For example, a number from “1” to “5” is assigned to each selection item name, and which selection item corresponds to what number is displayed on the display panel unit 5 at the same time. When the information that the input panel unit 2 is touched with the user's finger is received from the input detection unit 3, the time measuring unit 46 starts measuring time. For example, when one second has elapsed, the control unit 4 receives information on the number of touched points from the input detection unit 3. When the control unit 4 receives information on the number of locations, the control unit 4 executes event processing. The content of the event process is determined by information on the number of locations in contact with each other one second after contact and number information assigned to the selection item. When the number of locations in contact is zero, no event processing is executed and the process waits for selection input again.

  FIG. 10 is a selection input screen displayed on the display panel unit 5 in the touch panel input device 1 according to the third embodiment. Here, it is assumed that four selectable items displayed on the screen are calculated by the control unit 4. The user selects one item from the four selection items. The control unit 4 assigns numbers “1” to “4” to the four selection items, respectively. The number described in the left part of each selection item represents the number of locations in contact with the touch panel input device 1. “Selection item 1” indicates that the touch panel input device 1 needs to be touched in one place, “Selection item 2” requires two places, “Selection item 3” indicates three places, and “Selection item 4” indicates four places. . When the user touches the input panel unit 2, the control unit 4 starts measuring time by the time measuring unit 46 and executes each event process at the number of touched points after 1 second.

  FIG. 11 is an explanatory diagram illustrating a method in which a user selects and inputs “selection item 2” using the touch panel input device 1 according to the third embodiment. It is assumed that the user confirms an item to be selected and selects and inputs “Selection Item 2”. The user confirms the character “2” on the left side of “selection item 2”. The number “2” indicates that the touch panel input device 1 is touched at two places.

  The user touches two places on the touch panel input device 1 with two fingers and maintains the state for one second while keeping the contact. Then, the predetermined event processing corresponding to “selection item 2” is started by the control unit 4. Even if the user accidentally touches the touch panel input device 1 with three fingers at three locations, if one finger is released and two fingers are touched within one second after the start of contact, , “Selection item 2” event processing is started. Alternatively, when all three fingers that are in contact within 1 second after the start of contact are released, the control unit 4 again waits for selection input.

  FIG. 12 is a flowchart illustrating a processing example by the touch panel input device 1 according to the third embodiment.

  In step S31, the control unit 4 instructs the display panel unit 5 to display the selection items to which numbers are assigned.

  In step S <b> 32, the display panel unit 5 displays the selection items instructed from the control unit 4. On the other hand, the user confirms the number of the desired selection item and touches the input panel unit 2 with the same number of fingers as the number.

  In step S33, the input detection unit 3 detects whether or not the user touches the input panel unit 2. If the input detection unit 3 cannot confirm the contact of the input panel unit 2 in step S34, the process returns to step S33 and waits for the user to contact the input panel unit 2.

  Conversely, if the input detection unit 3 has confirmed contact with the input panel unit 2 in step S34, the input detection unit 3 determines in step S35 the number of contact points by the user (the number of the finger touching the input panel unit 2). Number).

  In step S36, the control unit 4 starts measuring time and waits until a predetermined time (1 second in the above example) elapses in step S37.

  After a predetermined time has elapsed, in step S38, the input detection unit 3 detects again the number of contact points by the user. In step S39, if there is a change in the number of contact points by the user, the process returns to step S33, and if there is no change in the number of contact points by the user, the process proceeds to step S40.

  In step S <b> 40, the control unit 4 starts executing predetermined event processing according to the number of contact points on the input panel unit 2 detected by the input detection unit 3.

  As described above, as described in the first to third embodiments, the label area is the conventional number when selecting and inputting from a plurality of selectable items displayed on the touch panel of a limited size. By operating with a plurality of fingers, erroneous contact with the touch panel can be prevented, and selection input intended by the user can be performed efficiently, accurately and easily. Therefore, the operability of the touch panel input device 1 is greatly improved.
