Abstract

PURPOSE:To input data based upon information on the movement, etc., of the view point of an operator by detecting the view point information on the operator, performing information processing according to the detection result, and inputting the processing result to an electronic computer. CONSTITUTION:The operator 11 puts on an eye camera 2 and views a predetermined visual field. An eye camera interface 3 detectors a signal corresponding to the movement, Then, the movement of the view point of the operator 1 is decoded by a signal processor 4 to decide what the operator 1 wants to transmit. This decision result is transmitted to the electronic computer 5 through an interface. This transmission result is fed back by an information transmitter 7 for the operator 1.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a data input device for an electronic computer, and particularly to an eye camera type data input device that allows data to be input using an eye camera. It is.

[Prior Art] FIG. 3 is a schematic diagram of a conventional keyboard type data input device disclosed in, for example, Japanese Patent Laid-Open No. 60-29825. In this third factor, 8 is a keyboard, 9 is an encoder, 10 is a calculation unit that processes a key press signal;
1 is a CPU, 12 is a ROM, 13 is a RAM, 14 is a clock circuit, and 15 is a counter.

Next, the operation will be explained. When the operator who is supposed to input data presses down any key on the keyboard 8,
A signal for recognizing the depressed key is sent from the keyboard 8 to the arithmetic unit 10 via the encoder 9, and necessary processing is performed within the arithmetic unit 10. Thereafter, input data corresponding to this key is input to the computer.

[Problems to be Solved by the Invention] In such conventional data input devices using a keyboard, the operator's intention is input only by pressing down on a key, so the operator has to judge which key to operate. However, the user is forced to recognize the position of the key and press the key down with pressure above a certain level. That is, there is a problem in that the operator cannot input data unless he performs the series of operations described above.

This invention was made in order to solve the above-mentioned problems, and is an eye camera type data input that allows data to be input from information such as the movement of the operator's viewpoint using an eye camera. The purpose is to obtain equipment.

[Means for solving problems] An eye camera type data input device according to the present invention.

An eye camera is attached to the operator who is to input data and detects the operator's viewpoint information, and the eye camera receives the operator's viewpoint information detected by the eye camera and performs the necessary information processing based on this viewpoint information. The device has a signal processing device for processing the signal processing device, and an interface for inputting the signal processing results by the signal processing device to an electronic computer.

[Function] In the eye camera type data input device of the present invention, the eye camera is attached to the operator, the operator's viewpoint information is detected by the eye camera, and the signal processing device performs appropriate information processing based on the detection result. The results of this processing are then input to a computer via an interface.

[Embodiments of the invention] Embodiments of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is an operator who is to input data, 2 is an eye camera attached to and used by the operator 1, 3 is an interface for the eye camera 2, and 4 is an operator's intention to be input by the eye camera. A signal processing device for making judgments based on the viewpoint information detection results; 5 is a computer into which the operator 1 attempts to input data; 6 is an interface between the signal processing device 4 and the computer 5 (an input device thereof); The operation of the sixth order, which is the information transmitter provided in the computer 5 to the operator 1, will be explained. First, the operator 1 who wants to input data wears the eye camera 2 and selects a pattern that corresponds to the information he/she wants to convey from among the patterns that cause the user to look at a predetermined field of view or move a specific viewpoint. to generate a predetermined pattern. For example, ABC...
If you want to select a pattern that corresponds to "A" from ..., all you have to do is stare at a certain part of your field of vision for 3 seconds where the data pattern corresponding to "A" exists. . As a result, when the operator wants to input the character information "A", he or she performs the action of staring at the character "A" for 3 seconds, and the eye camera interface 3 detects a signal corresponding to that action.After that, The signal processing device 4, which determines the operator's intention from the viewpoint information results, decodes the operator's viewpoint movement and determines what the operator is trying to convey.
It is determined that the character is rAJ.

This determination result is then transmitted to the electronic computer 5 via the interface 6. Note that this transmission result is fed back to the operator 1 by the information transmitter 7, so the operator 1 continues the input work in the same manner as a conventional keyboard-type data input device while checking the input result. Can be interrupted and corrected.

In addition, in the above embodiment, an example was shown in which a person looks at a specific position for a certain period of time, but it is also possible to look at multiple positions in succession, and the viewpoint information input from the eye camera 2 can be used even if only one eye is used. good.

Further, as shown in FIG. 2, the screen of a visual display 16 attached to the computer 5 is set as a predetermined field of view, and various information screens can be switched and displayed using the visual display 16, or An arbitrary screen may be specified in advance so that the input by the operator 1 is easy and reliable.

[Effects of the Invention] As described above, according to the present invention, information on the operator's intention can be transmitted based on the position and movement of the operator's viewpoint. This has the effect that even people who do not have the motor skills or functions to operate a conventional keyboard can enter data.
