(57) [Abstract] [Purpose] To realize a pointing device that controls the position of a pointer on a touch screen at a place different from the pointer. A pointer display means for pointing a certain place on the screen, an input device for determining a position where the pointer is displayed on the screen, a position conversion means for coordinate-converting a signal from the input device, and the position. Control means for inputting a signal from the converting means and outputting the data to the display circuit, and for outputting the setting to the position converting means at the time of coordinate conversion, and for displaying the pointer from the data from the controlling means on the screen. A pointing device having a display circuit for converting into display data and outputting to display means.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pointing device, and more particularly, to a pointing device in which a positional relationship between an input position on a touch screen and a pointer is improved.

[0002]

[Prior Art]

 FIG. 5 shows the operation of controlling the position of the pointer on the conventional touch screen. At this time, the position where the finger was placed was detected and the pointer was placed at that position.

[0003]

[Problems to be solved by the device]

 For this reason, there are problems such as covering the pointer with a hand when moving the pointer. Therefore, an object of the present invention is to realize a pointing device which controls a position of a pointer on a touch screen at a place different from a pointer.

[0004]

[Means for Solving the Problems]

 The present invention provides a display means for displaying a pointer for pointing a certain place on the screen on the screen, an input device for determining the position where the pointer is displayed on the screen, and a signal from the input device as a coordinate. Position conversion means for conversion, control means for inputting a signal from the position conversion means and outputting data to the display circuit, and for outputting the setting to the position conversion means at the time of coordinate conversion, data from the control means Is a pointing device characterized in that a display circuit for converting the pointer into display data for displaying on the screen and outputting to the display means is provided.

[0005]

[Action]

 Since a window is provided on the screen and the pointer movement direction is entered in it, the position of the pointer can be controlled on the touch screen at a location different from the pointer.

[0006]

【Example】

 FIG. 1 is a basic configuration diagram of the present invention.

In the figure, reference numeral 1 denotes an input device which determines a position where a pointer is shown on the screen. Specifically, a window is provided on the screen of the touch screen to detect the distance and direction of the finger movement. Reference numeral 2 denotes a position conversion means, which performs coordinate conversion of the signal from the input device 1 based on the setting from the control means 3. The control means 3 inputs the signal from the position conversion means 2 and outputs the data to the display circuit 4, and also outputs the setting for coordinate conversion to the position conversion means 2. The display circuit 4 converts the data from the control means into display data for displaying the pointer on the screen. A display means 5 displays a pointer for pointing a certain place on the screen on the screen. In this case, the control means 3 and the position conversion means 2 are considered to be software programs executed by the CPU or the like.

The operation of such a configuration will be described. First, the input device 1 will be described. FIG. 2 shows an example of detection of the input device 1 by infrared rays. In this way, infrared rays run vertically and horizontally on the screen of the touch screen, and when a finger or the like touches the infrared rays, the X and Y coordinates are detected. FIG. 3 shows a screen during operation. In the figure, 10 is a pointer and 20 is a sensing unit. This sensing unit 20 is a window provided on the screen of the touch screen, and a display as shown in FIG. That is, at this time, since the normal touch screen operation is performed in this window, the input device 1 detects how much the finger has moved in the X and Y directions. The detected result is output to the position conversion means 2. In the position conversion means 2, information such as the position of the pointer 10 on the screen or the ratio of the moving distance detected by the input device 1 to move the pointer 10 is input from the control means 3, and the pointer 10 on the screen is input. Find the position. The position obtained here is output to the display circuit 4, and the pointer 10 is displayed on the display means 3. With this series of operations, the position of the pointer can be controlled on the touch screen at a place different from the pointer.

FIG. 4 shows a specific operation method. Thus, the pointer 10 also moves in the direction in which the finger moves, and the moving distance of this finger may be set by the control means 3 or the like. The movement within the window indicates the relative distance.

[0010]

[Effect of the device]

 As is clear from the above description, the present invention has the following effects. You can control the position of the pointer on the touch screen in a place different from the pointer. In addition, since the proportion of movement can be expanded or reduced, finer movement control can be performed.
