Abstract

PURPOSE:To improve working efficiency by providing a light emitting means to emit focusing light, a display means, a light receiving means, and a coordinate position judging means. CONSTITUTION:The titled device is constituted of a display device 1, a display 2, a half-mirror 3, a light receiving device 4, a light emitting device 5, a coordinate position judging device 6, and the focusing light 7. When a worker faces with the display 2 after loading the light emitting device 5 at the head of the worker, the focusing light 7 emitted from the light emitting device 5 is separated to the display 2 and the light receiving device 4 by the half-mirror 3, then, projected. An X-axis and a Y-axis can be found from the position of the focusing light 7 projected on the light receiving device 4 by the coordinate position judging device 6. In such a way, it is possible to obtain a coordinate position desired by the worker by the action of the head of the worker, and to improve the working efficiency since no disturbance for another work such as the input of a keyboard, etc. is generated by such action.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to coordinate input when using a computer.

2. Description of the Related Art A conventional coordinate input device, as shown in FIG. For those that obtain X and Y coordinate data, or as shown in Figure 4, hold the stylus 16 in one hand and
An example of this is one that obtains X and Y coordinate data from a sensor 18 inside the tablet 17 by pressing the tip of the tablet against the tablet 17.

Problems to be Solved by the Invention However, with the configuration of the coordinate input device described above, when changing input coordinates, it is necessary for the operator to hold the coordinate input device by hand. When doing this, work efficiency decreases.

Means for Solving the Problems The present invention for solving the problems described above includes a light emitting means for emitting focused light, a display means, and when the focused light emitted from the light emitting means is irradiated onto the display means. , a coordinate input device comprising a light receiving means capable of sensing this focused light, and a coordinate position determining means for determining the position of the focused light irradiated onto the light receiving means.

Effect ``) According to the configuration described above, when focused light emitted from a light emitting means fixed to a part of the body is irradiated onto the display means, part or all of the focused light is also irradiated onto the light receiving means, and the focused light is emitted from the light emitting means fixed to a part of the body. From the light receiving means irradiated with light, the coordinate position on the display means can be determined by the coordinate position updating means.

Embodiment A first embodiment of the present invention will be described with reference to FIG.

The coordinate input device of the first embodiment includes a display device 1.
Display 2. Half mirror 3, light receiving device 49 light emitting device 5. Coordinate position determination device6. It consists of focused light 7.

When a worker wears the light emitting device 5 on his head and faces the display 2, the focused light 7 emitted from the light emitting device 5 is divided by the half mirror 3 and irradiated onto the display 2 and the light receiving device 4. . A coordinate position determining device 6 determines the X and Y coordinates from the position of the focused light 7 irradiated onto the light receiving device 4.

In the coordinate input device of this embodiment, the coordinate position desired by the worker can be obtained by the movement of the worker's head, and does not interfere with other tasks such as keyboard input, so that work efficiency can be improved.

In this embodiment, if the thickness of the half mirror 3 is thin, even if the angle at which the focused light is irradiated from the light emitting device 6 to the display 2 changes, the accuracy of the coordinate position obtained by the coordinate input device will be maintained. The operator can work with a large degree of freedom regarding the work position without changing the position.

Next, a second embodiment will be described with reference to FIG.

The coordinate input device of the second embodiment includes a display device 8.
Display 9. Light receiving device 10. Light emitting device 11. Coordinate position determination device 12. From the focused light 13.

Here, the light-receiving device 1o in this embodiment is constructed of, for example, a transparent film that cannot block the screen displayed on the display 9, and reacts only to the focused light 13 emitted from the light-emitting device 11. For example, there are those that react only to the focused light 13 of a specific frequency emitted by the light emitting device 11, those that react only to the focused light 13 that has a specific blinking frequency that is different from the blinking frequency of a display display or room lighting, and This can be realized by configuring a device that has a high sensing threshold and reacts when it receives a high amount of focused light emitted by the light emitter 11.

The worker wears the light emitting device 11 on his head and displays the display 9.
When the user turns toward the user, the display 9 and the light receiving device 10 are irradiated with focused light 13 emitted from the light emitting device 11 . A coordinate position determining device 12 determines the X and Y coordinates from the position of the focused light 13 irradiated onto the light receiving device 1o.

With the coordinate input device in this embodiment, as in the first embodiment, the worker can obtain the desired coordinate position by the movement of the worker's head, and keyboard input, etc., does not interfere with the pond work, so the work can be done easily. It can increase efficiency.

Effects of the Invention As explained above, according to the present invention, one hand is not occupied when inputting coordinates, so it is possible to significantly improve work efficiency when inputting coordinates in parallel with keyboard input.
