  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a touch panel device according to an embodiment of the present invention. In this figure, the touch panel device according to the present embodiment includes a touch panel 10, a display 11, a touch panel event / real time processing unit (coordinate information output means) 12, and a buffer built in the touch panel event / real time processing unit 12. 13, a GUI state transition processing unit (object display transition unit) 14, and a drawing control unit (drawing control unit) 15.

  The touch panel 10 is arranged on the screen of the display 11, detects a touch on the screen with a user's finger or a dedicated pen, and outputs position information at that time. Touch panel touch detection includes pressure-sensitive, electrostatic, infrared, and ultrasonic methods. For example, the pressure-sensitive method detects pressure changes, and the electrostatic method detects electrical signals due to static electricity. . The display 11 is a display device such as an LCD or a CRT display, and displays objects such as graphic buttons and icons.

  The touch panel event / real-time processing unit 12 has a buffer 13 for storing position information. The buffer 13 stores the position information fetched from the touch panel 10 and reads it in the stored order as GUI information as event information. Input to the state transition processing unit 14. The touch panel event / real-time processing unit 12 inputs event information indicating the position of the touched finger to the drawing control unit 15. The generation and output of event information indicating the position of the touched finger has not been performed conventionally, and is one of the points of the present invention.

  By inputting event information indicating the position of the touched finger directly to the drawing control unit 15 instead of inputting it to the GUI state transition processing unit 14, it is possible to display it on the display 11 without time lag. Thereby, even when the GUI process is heavy, the user can immediately confirm that the touch operation has been performed, and can prevent the touch operation from being performed many times in succession.

  FIG. 2 is a diagram showing a data structure of the buffer 13 incorporated in the event / real-time processing unit 12 for the touch panel. The count area A1 in which the count value for measuring the real time is recorded and the touch on the touch panel 10 are shown. A coordinate area A2 where the position is recorded, a flag area A3 indicating the presence / absence of a touch on the touch panel 10 and dragging, and a done flag area A4 indicating the end of one event. The buffer 13 is a so-called ring buffer in which data is overwritten from the beginning when the data is stored until it is full.

  As shown in FIG. 2, when the touch panel 10 is touched, coordinate data (for example, (10, 20)) of the touch position is stored, and the flag is set to “on”. The done flag is set to “1” by a signal sent from the GUI state transition processing unit 14 at the time when the current event ends, and is set to “0” until then.

  Further, when a drag operation is performed on the touch panel 10, the coordinate data (for example, (11, 22)) of the start point at that time is stored, and the flag becomes “drug”. After that, when the user moves in the dragged state, coordinate data is stored every time counting up. Thereafter, when the end point is reached, the flag is changed from “drug” to “off”. The done flag is set to “1” according to a signal sent from the GUI state transition processing unit 14 after the drag event ends, and is set to “0” until then.

  Returning to FIG. 1, the GUI state transition processing unit 14 performs a process of transitioning the state of the graphic object displayed on the display 11 by the drawing control unit 15 in accordance with the event information from the touch panel event / real time processing unit 12. That is, a process for transitioning the graphic object corresponding to the touch position of the touch panel 10 to the touched object is performed.

  For example, when the object is a button and a position on the button of the touch panel 10 is touched, the button is changed to a pressed button. The GUI state transition processing unit 14 performs a process of transitioning the graphic state according to the occurrence of an event, and then outputs a signal for setting the done flag of the buffer 13 corresponding to the event to “1” for the touch panel event / real time processing unit 12. To enter.

  The drawing control unit 15 draws a predetermined object on the display 11 and draws the object after the transition when information for changing the state of the object is input from the GUI state transition processing unit 14. In addition, when a drag operation is performed, the start point and the end point, and the locus between them are drawn. Further, when information indicating the position of the finger is input from the touch panel event / real-time processing unit 12, a graphic of the size of the fingertip is drawn on the corresponding graphic object.

Here, FIG. 3 is a diagram illustrating an example of a graphic display when the button BT is touched. When the button BT is touched, a graphic finger indicating the fingertip as shown in FIG. 3A is displayed so as to overlap the button BT until the end of the event, and a thick border around the portion overlapping the button BT is displayed. L F1 is displayed.

When the event ends, a thick frame line L F1 is displayed as a thin frame line L F2 as shown in FIG. When the button BT is touched in this way, a graphic FING indicating the fingertip is displayed so as to overlap the button BT, and a thick frame line L F1 is displayed around the portion overlapping the button BT of the graphic FING indicating the fingertip during the event processing. Is displayed with a thin frame line L F2 from the time when the event processing is completed.

Thereby, the user can visually confirm the sensitivity of the touch panel 10. As a result, when an invalid operation such as pressing an unusable button during event processing is performed, it is possible to easily distinguish whether the operation itself is invalid or a sensitive touch panel 10 error. Thus, the user can reduce the feeling of stress. In other words, if it is displayed with a thick frame line L F1 when it is touched, it can be determined that the operation has been accepted, and thus it can be seen that the operation is invalid when the same operation is performed thereafter. On the other hand, if it is touched but not displayed with the thick frame line L F1 , it is understood that it is a sensitivity error.

  The graphic FING indicating the user's fingertip may be erased when the done flag becomes “0” or after a certain time.

On the other hand, FIG. 4 is a diagram illustrating an example of a display when a drag operation is performed on the touch panel 10. As shown in this figure, when a drag operation is performed, the start point and the end point are displayed with a thick frame line L F3 about the size of the fingertip, and the trajectory from the start point to the end point is displayed with a thin frame line L F4 . indicate. By displaying the start point and the end point with a thick frame line L F3 , the start point and the end point can be clarified. Thereby, the user can visually confirm the sensitivity of the touch panel 10. Note that the display may be erased by the drag operation when the done flag becomes “0” or after a certain time.

The above is summarized as follows.
When a position on the touch panel 10 corresponding to a graphic object (for example, a button) displayed on the display 11 is touched, a frame line L F1 that is about the size of a fingertip and thicker than usual is superimposed on the object. Drawing is performed on the display 11, and this drawing state is continued until the event processing is completed. When the event processing is completed, the frame line L F1 is displayed with a thin frame line L F2 . Thereafter, the frame line L F2 is erased when a certain time elapses or when the done flag becomes “0”.

When drag operation to move the graphic on the display 11 is a display object (e.g. an icon) is executed, and from the start point is displayed in the start and end points respectively of the fingertip size of about thick border L F3 The trajectory up to the end point is displayed with a thin frame line LF4 . After reaching the end point, the frame lines L F3 and L F4 are erased when a certain time elapses or when the done flag becomes “0”.

Thus, according to the touch panel device of the present embodiment, a frame about the size of the fingertip is displayed at a position on the display screen corresponding to the touch position of the touch panel 10 with a frame line L F1 that is thicker than usual. If there is a graphic button (object), the graphic button (object) is drawn so as to overlap with the button, and when the event processing by the current touch is finished, the thick frame line L F1 is changed to the thin frame line L F2 . When a drag operation is performed, the start point and the end point are displayed with a thick frame line L F3 about the size of the fingertip, and the locus between the start point and the end point is displayed with a thin frame line L F4 .

Therefore, if it is displayed with a thick frame line L F1 when touched, it can be seen that the operation is accepted, and if the same operation is performed thereafter, the operation is invalid. If it is touched, but it is not displayed with the thick frame line L F1 , it can be understood that it is a sensitivity error, so that it is possible to reduce the stress of the user due to invalid operation or sensitivity error.

  In the above-described embodiment, a frame line about the size of the fingertip is displayed, but the following may be used instead of the frame line. Further, in each of the following cases including the frame line, whether the event process is being performed or the event process has been completed can be confirmed by, for example, changing each density.

(1) Draw a semi-transparent circle (ellipse) where objects such as buttons and icons can be seen with the size of a fingertip.
(2) In color display, monochrome display, that is, black and white circle (ellipse) is drawn.
(3) Draw a circle (ellipse) of color inversion, that is, negative / positive inversion.
(4) Draw a distorted circle (ellipse).

  Also, in the above embodiment, the frame line such as the touch position is changed from the thick line to the thin line, but the line type such as the line width and the line shape such as the thin line to the thick line and the solid line to the dotted line is changed. You may make it do.

  The present invention has an effect that, when an invalid operation such as touching a disabled button during event processing is performed, it is possible to clearly distinguish whether the operation itself is invalid or a touch panel missensitive. In addition to information devices such as car navigation systems, personal computers, ATMs, mobile phones, and PDAs, it can be applied to all devices that can use touch panel devices such as home appliances such as TVs and microwave ovens.
