Abstract

PURPOSE:To rapidly and accurately move a cursor position and to make it unnecessary to prepare a specific space for operation for moving the cursor by arranging a contact type coordinate input device in front of the screen of an image display device so as to superpose the two units to each other. CONSTITUTION:When an optional point of the contact type coordinate input device 2 superposedly arranged in front of the screen of the image display device 1 is touched with a finger or the like, the touched position is recognized by a touched position recognizing function of an electronic computer, the recognized result is coordinate-converted by a coordinate conversion function and the cursor is displayed at a position just under the touched position of the device 2 on the screen of the device 1. Thereby the cursor can be easily, rapidly and accurately moved by moving the touch position and a specific operation space for cursor movement can be omitted, so that the installation place of the device can be made compact.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to electronic computers, word processors, etc., which are equipped with a CRT display device, which is one of the image display devices, and a keyboard device, which is one of the input devices. It relates to various information processing devices.

[Conventional technology]

Conventional information processing devices are configured to move a cursor displayed on the screen of an image display device using various input devices such as a keyboard device, a mouse, and a light pen.

For example, to move a cursor on the screen using a keyboard device, assign cursor movement commands up, down, left, and right to specific keys (cursor keys) on the keyboard device, and input coordinates by operating the specific keys to move the cursor up and down. Move it to either the left or right. In this case, the cursor is moved by pressing the cursor key described above, and the cursor is moved by a distance corresponding to the duration or the number of cursor key operations, so it takes a long time to move the cursor to a distant position. The problem was that it took time.

In addition to moving the cursor using the cursor keys as described above, the cursor may also be moved by inputting coordinates using a mouse or light ben.

In this way, by using the mouse or light pen, you can quickly move the cursor to any desired position by moving the mouse or light pen.

To move the cursor, in addition to a mouse or a light pen, a contact type coordinate input device such as a touch panel is used, and this is superimposed on the screen of a thin flat panel display device, and the contact type coordinate input device on the screen is used. An information processing device that moves a cursor by inputting coordinates by directly touching the cursor has also been proposed (for example, Japanese Patent Laid-Open No. 78621/1983).

FIG. 7 shows a schematic diagram of an information processing device using a contact type coordinate input device. In FIG. 7, 31 is a contact type coordinate input device consisting of a touch panel, and 32 is, for example, a CR
The image display device is a T-display device, 33 is a keyboard device, and 34 is a thin flat panel display device.

In such an information processing device, the contact type coordinate input device 31
is superimposed on the thin flat panel display device 34 that displays an image such as a keyboard pattern, used as the keyboard device 33, and set to cursor movement mode, so that the screen of the image display device 32 and the contact type coordinate input device can be connected. 31 in a one-to-one correspondence, the contact type coordinate input device 3
A cursor is displayed on the corresponding part of the image display device 32 corresponding to the part touched by the user.

[Problem to be solved by the invention]

When moving the cursor using a mouse or light pen as described above, there is a problem that an operation space is required to move the mouse or light pen, which makes it impossible to downsize the installation location of the device. Alternatively, since the operation is indirect using a light pen, there is a problem that malfunctions are likely to occur.

Similarly, the information processing device shown in FIG. 7 has a configuration in which the image display device 32 and the contact type coordinate input device 31 are separated, and the image display device 32 is operated by touch operation of the contact type coordinate input device 31. Moving the cursor, that is, controlling the cursor position, is an indirect operation, which can easily cause malfunctions.

In addition, in information processing devices equipped with a contact type input device on the front of the screen of an image display device such as a conventional CRT display device, although it has input functions such as selecting command menus, it is difficult to move the cursor. It has no control function.

Therefore, an object of the present invention is to provide an information processing device that can easily, quickly, and accurately move the position of a cursor displayed on the screen of an image display device, and that does not require a special operation space for moving the cursor. That's true.

[Means to solve the problem]

The information processing device of the present invention includes a contact type coordinate input device having a coordinate system that is arranged in front of a screen of an image display device and has a one-to-one correspondence with a coordinate system on the screen; A touch position recognition function that recognizes the touch position of a finger, etc., a coordinate conversion function that converts the touch position recognized by the touch position recognition function into coordinates, and a coordinate conversion function on the screen of the image display device. It also has a cursor display function that displays a cursor at the position corresponding to the entered input coordinates.

[For production]

According to the configuration of the present invention, when a finger or the like is used to touch any point on the contact type coordinate input device arranged in front of the screen of the image display device, the touch position of the contact type coordinate input device is changed to the touch position recognition function. The recognition result is converted by the coordinate conversion function, and based on the input coordinates obtained by the coordinate conversion function, the cursor display function displays a point on the screen of the image display device just below the touch position of the contact type coordinate input device. The cursor will be displayed at the location.

The detection of this touch operation and the display of the corresponding cursor are repeated within a very short period of time, and when the touch position is moved linearly while sliding a finger etc. on the contact type coordinate input device, The cursor position moves linearly. Furthermore, when the touch position is moved in a dotted manner without sliding the finger or the like on the contact type coordinate input device, the position of the cursor jumps accordingly.

At this time, a contact type coordinate input device corresponding to the screen of the image display device on a one-to-one basis is placed in front of the screen of the image display device, and the screen of the image display device corresponding to the touch position of the contact type coordinate input device is placed in front of the screen of the image display device. Since the cursor is displayed at the corresponding position on the screen of the image display device, the position where the cursor should be displayed on the screen of the image display device and the position where the touch operation should be performed on the contact type coordinate input device exactly overlap, and the touch position can be moved. By doing so, the cursor can be moved easily, quickly and accurately.

Furthermore, since the coordinates are input using a contact input type coordinate input device superimposed on the screen of the image display device, a special operation space for moving the cursor is not required.
