Abstract

<P>PROBLEM TO BE SOLVED: To provide a position input device which allows coordinate information to be inputted at one arbitrary point in the air regardless of the absence of a plane. <P>SOLUTION: When a main body 10 is tilted to the front, the rear, the right, or the left at one arbitrary point in the air, a biaxial acceleration sensor 10a detects tilts of two axes as voltage differences respectively and converts them to a movement direction and an extent of movement by an AD converter and a control part and outputs them. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to a position input device that designates the position of a cursor on a display screen according to tilt information.

Patent Publication No. 7-5983 Patent Publication 2002-287890 The mouse is a kind of computer position input device used for designating a cursor position on a display screen such as a CRT display. For example, the mouse can be used to read the position information of XY by electrically detecting the rotation angle of a sphere attached to the bottom surface, or to detect frictional vibration or optical reflection to detect X-Y position information. Some read -Y position information.

However, since all of the conventional mice described above need to be moved on a flat work table, work with the mouse is accompanied by spatial restrictions. Therefore, the mouse could not be used depending on the work environment.

An object of the present invention is to provide a position input device that eliminates such drawbacks and can be used in any environment.

In the present invention, in order to solve the above-mentioned problem, in a position input device that designates the position of the cursor on the display screen in accordance with the tilt information, movement information detection means that incorporates an acceleration sensor that detects a voltage difference at the time of tilt, A position calculating unit that obtains a movement amount in each direction from a voltage difference at the time of tilting, a position that receives information on the movement amount and the movement direction, obtains a cursor position on a display screen, and outputs a movement command to the cursor A position input device comprising: generating means.

In the present invention, the movement information detecting means in the position input device incorporates a biaxial acceleration sensor for detecting a voltage difference during tilting. For this reason, movement in the X and Y directions can be performed at an arbitrary point in the air with an inclination by front / back / left / right rotation.

Further, since the horizontal position of the acceleration sensor is the origin of the position information, the cursor can be moved to a desired position by tilting with respect to the horizontal position. Therefore, it can be used without a flat work table, and can be used anywhere as long as there is a space that can rotate back and forth and right and left around the position input device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a position input device of the present invention. In the figure, the movement information detecting means 1 has a built-in biaxial acceleration sensor 1a, and the acceleration sensor 1a detects biaxial voltage differences Vx and Vy when the device itself tilts. The movement amount calculation means 2 calculates the direction and movement amount from the biaxial voltage difference Vx, Vy detected by the acceleration sensor 1a.

The position generation means 3 receives the information on the direction and the movement amount, obtains the movement position of the cursor 4a on the display screen 4, and outputs a movement command to the cursor.

In FIG. 2, the position input device includes a biaxial acceleration sensor 10 a, click buttons 11 and 12, a scroll 13, a control unit 14, and a transmission unit 15 housed in the main body 10.

The biaxial acceleration sensor 10a has a known configuration and is commercially available. In the figure, the biaxial acceleration sensor 10a is arranged so that the left-right direction is the X-axis and the front-rear direction is the Y-axis. Thereby, the biaxial acceleration sensor 10a detects the inclination when the main body 10 inclines back and forth and left and right at an arbitrary point in the air as a voltage difference, and converts it into a moving direction and a moving amount by the control unit and outputs it.

The direction is determined depending on whether the voltage difference is positive or negative with respect to the center voltage value of the X and Y axes of the biaxial acceleration sensor due to the inclination, and the amount of movement is determined by the voltage value.

Furthermore, since the horizontal position of the acceleration sensor is the origin, the cursor can be moved to a desired position by tilting in a desired direction while viewing the cursor on the display screen.

The transmission unit 15 is configured to transmit the coordinate information and control information from the control unit 14 as a transmission signal such as an electric signal, an infrared light signal, and a radio signal.

The present invention can be attached to the back of the hand of FIG. 3 from the method of operating at an arbitrary point in the air, attached to the head like the hat of FIG. 4, or operated on the table as a sphere of FIG. 5.

It is a block diagram of the position input device of the present invention. It is a figure which shows the mouse | mouth as a movement information detection means. It is a figure which shows the mouse attached to the back of the hand as a movement information detection means. It is a figure which shows the mouse attached to the cap as a movement information detection means. It is the figure which attached the base to the spherical mouse | mouth as a movement information detection means.
