【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of the present invention. In the figure, 1 is a screen of a display device such as a CRT, 2 is a designated position detecting means for detecting a designated position of a finger or the like on the display screen, or a position where the finger is pulled out. An optical type that detects a specified position depending on the position where the light is blocked, or a type that detects a resistance change due to finger pressing is used. The designated position detecting means 2 outputs the designated position on the screen as a signal of X-axis coordinates and Y-axis coordinates.

Reference numeral 3 designates a designated position signal from the designated position detecting means 2 and inputs the designated position (the designated position (the designated position is selected at a touch-down timing when a finger is pointed, and the finger is displayed on the screen. It is determined whether the mode executed at the lift-off timing separated from the top (or pulled out) and the mode selected and executed at the touch-down timing are within the preset valid touch target. It is an effective touch area judgment means.

When the effective touch area determining means 3 detects that the designated position is within the valid touch target, 4 moves the cursor or the icon KL to the designated position, and moves the cursor or the icon KL to, for example, a high level. It is a first cursor display means for displaying in a first display form such as a light display.

When the effective touch area determination means 3 detects that the designated position is outside the valid touch target, 5 moves the cursor or icon KL to the designated position, and moves the cursor or icon KL to the first position. The second cursor display means for displaying in a second display form such as a border (or white) display that can be distinguished from the first display form. 6 is a keyboard, 7 is a mouse, and a cursor or an icon can be moved and operated by these pointing devices.

The operation of the apparatus thus configured will be described below. It is assumed that, for example, a graphic, an overview screen, a menu screen, or the like is drawn on the screen 1 by a screen program. In addition, a touch target 31 is defined on the screen at a predetermined position according to the content of the screen drawn on the screen. In FIG. 1, only one touch target is shown for convenience of explanation, but normally, a plurality of touch targets are provided for each screen.

It is assumed that the operator has performed a touch screen operation for designating a touch target 31 for instructing to open a window screen in which, for example, specific information is displayed, for example, in a graphic displayed on the screen. Then, the designated position detecting means 2 outputs the designated position on the screen as a signal of the X-axis coordinate and the Y-axis coordinate. The valid touch area determining means 3 inputs the designated position signal from the designated position detecting means 2 and determines whether or not the designated position is within the valid touch target of the preset touch target 31. .

Here, when the designated position of the finger designated by the operator is outside the touch target 31, the effective touch area determination means 3 detects that the designated position is outside the valid touch target. . In response to the detection result, the second cursor display means 5 moves the cursor or the icon KL to a designated position designated by the operator, and the cursor or the icon KL is, for example, outlined (or outlined). ) Display in a second display form such as a display.

If the designated position of the finger designated by the operator is within the touch target 31, the effective touch area determination means 3 detects that the designated position is within the valid touch target, and the first cursor display is performed. The means 4 moves the cursor or the icon KL to the designated position and makes the cursor or the icon KL highlighted, for example. When such a designation to the effective touch area is detected, the corresponding window is displayed at the timing depending on the mode to be executed by the lift-off of the finger described above or the mode to be selected and executed by the touchdown, or The operation defined in the touch area will be performed.

An operation in which the operator touches the CRT screen with the finger (inserted), that is, moves the finger position while operating the touch screen (called a drag operation) When a finger is put into the effective touch target 31 from outside the touch target 31, the effective touch area determination unit 3 detects it and the display of the cursor or the icon KL is outlined (or white). The display mode is changed from the (without) display mode to a highlight display (first display mode) indicating that the touch screen operation is effective.

FIG. 2 is a schematic flowchart showing the above operation. Depending on whether or not the designated touch position on the screen is within a valid touch target, a cursor or an icon is displayed at the designated touch position in a different display form.

In this way, the operator can intuitively grasp from the cursor display whether or not the touch screen operation is effectively performed. In this embodiment, the first display form showing that the touch screen operation is valid is highlighted, and the second display form showing that the touch screen operation is invalid is a blank form. However, if these are display forms that can be distinguished from each other, for example, the display color may be changed, or a blinking display form may be adopted.

Further, the operation of the cursor or the icon may be commonly performed by a keyboard or a mouse in addition to the operation by the touch screen.
