The signals are sent to a CPU1 through an analog switch 9, amplifier 10, and AD converter 11 and calculated. After the calculation, coordinates of a cursor, etc., are displayed at the point on the CRT2, to which the operator pays his attention.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a coordinate value input device for a computer.

BACKGROUND ART Conventionally, input methods such as a joystick, a light pen, and a mouse have been used to input coordinate values into a computer.

However, since all of these methods require operators to operate using their hands, they must take their hands off the keyboard when inputting coordinate values, making it difficult to perform tasks that involve inputting characters, numbers, etc. had the drawback of poor operability.

There is also a method of detecting the movement of the worker's viewpoint from the eyeball potential, but this method requires a large-scale and expensive device, and requires the installation of various detection devices on the worker's face, etc. However, there was a drawback in that it increased the burden on the workers.

Purpose of the Invention The present invention solves the above-mentioned deficiencies in the prior art, provides a simple and inexpensive device configuration, reduces the burden on the operator, and eliminates the need to take one's hands off the keyboard. To provide a coordinate value input device for a computer which can input coordinate values by simply changing the direction of a worker's face with respect to a CRT display, has good operability, and can improve work efficiency. With the goal.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention includes a light emitting element provided either on the face of the worker or around the 011'LT display, and a light emitting element that directs the light from the light emitting element to the worker's face. The OR system receives the light directly depending on the position and direction of the worker's head, or indirectly through a reflector attached to the worker's face, and generates a signal according to the intensity of the light.
(3) To display the coordinates of a cursor, etc. at the position of the operator's attention on the ORT display based on the multiple light receiving elements arranged around the T display and the signals from the light receiving elements. and control means.

EXAMPLE An example of the present invention will be described below with reference to the drawings.
In the drawing, 1 is a word processor or computer.

This is an OPU (central processing unit) of a computer such as a computer, and is capable of performing various calculations necessary for carrying out the present invention. An OAT display 2 capable of displaying the output of the 0PU1 is provided on the top of the 0PU1, and the operator can work while checking the display on the ORT display 2. Further, a keyboard 3 is provided at the front of the 0PU1, and data can be entered using the keyboard 3.

A light emitting element 4 is disposed around the front surface of the CIT display 2, at the top of the enclosure, and emits infrared light toward the operator in front of the ORT display 2. Reflective glasses 5 as reflectors capable of removing ultraviolet rays are worn on the worker's face, and reflect the light from the light emitting elements 4 according to the position and (4) direction of the worker's head. There is. At the left and right sides and at the bottom of the front surface of the CRT display 2, first
- An eighth light receiving element (i, 7.a) is provided, which indirectly receives the light from the light emitting element 4 as reflected light from the reflective glasses 5, and generates a signal according to the intensity of the light. It looks like this.

As shown in FIG. 8, the first to eighth light receiving elements 6, 7
．． An analog switch 9 is connected to 8, and the signals from each of the light receiving elements 6 to 8 are sequentially sent to the amplifier 10 based on a command from 0PU1.

A 4-converter 11 is connected to the amplifier 10, which converts the amplified electrical signal number into a digital signal and outputs it as 0PU.
1 processing is possible. In this embodiment, the control means is composed of OF'ff1K, and each light receiving element 6
The signal from the % converter 11 based on .
The position and direction of the head of the worker wearing the reflective glasses 5 are calculated, and the coordinates of a cursor or the like are displayed at the position on the display 2 that the worker is paying attention to. .

Next, the operation of this coordinate input device will be explained according to the flowchart shown in FIG.

Now, as shown in FIG. 1, when a worker inserts data by operating the keys on the keyboard 3 while wearing reflective glasses 5, the data displayed on the OAT display 2 is When the light from the light-emitting element 4 is reflected by the reflective glasses 5' and reaches each light-receiving element 6, 7, 8, for example, the second
A signal is generated from each light receiving element 6.7.8 according to the distribution of reflected light as shown by concentric circles in the figure.

The signal is sent to 0PU1 via the analog switch 9, amplifier 10, and converter 11 shown in Fig. 8, and the center of the reflected light distribution, that is, the position and direction of the worker's head, is calculated at OPU1. Then, the coordinates of a cursor or the like are displayed on the OR'l' display 2 at the position that the worker is paying attention to.

Therefore, the operator can freely move the cursor position without taking his hands off the keyboard 3, simply by shaking his head left and right or up and down and focusing on a predetermined position on the OR'l' display 2. This allows data insertion work to be performed efficiently.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may be configured as follows.

(1) Instead of the reflective glasses 5, a reflective dormitory mirror that can be attached to the forehead etc. can be used as a reflector.

(2) The light emitting element 4 is attached to the forehead of the worker without using a reflector, and the light from the light emitting element 4 is configured to directly reach the light receiving elements 6 to 8.

(3) Light transmission distance from the light emitting element 4 to the light receiving elements 6 to 8 based on the total amount of light detected by each of the light receiving elements 6 to B, that is, the spatial distance between the ORT display 2 and the worker's head , and thereby add the depth coordinate value to the vertical and horizontal two-dimensional coordinates in the above embodiment, thereby making it possible to input the three-dimensional coordinate value.

Effects of the Invention As detailed above, the present invention has a simple and inexpensive device configuration, reduces the burden on the operator, and eliminates the need to take one's hands off the keyboard. Coordinate values can be input simply by changing the direction of the worker's face, providing excellent operability and improving work efficiency.
