JP2001188645A - Joy stick - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it possible to use a joy stick by a physically handicapped person, a healthy person of a state in which his (or her) hands can not be used, a state in which the hands are made to intentionally disabled from being used or a state in which the hands are made intentionally not to be used by eliminating the necessity of manual operation. SOLUTION: A sensor 1 detects living body information from each part of a human body and an information collection unit 2 unifies detected information to conduct the impedance transformation of a signal, the removal of noise, etc. A data processing unit 3 executes data statistic processing and classifies categories. A joy stick driver 4 outputs a joy stick output on the basis of the result of category classification.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Conventional joysticks are premised on manual operation. However, it is used in a device in which a person with a physical disability in hand operation or a handicapped person cannot use a hand or intentionally disables or does not use a hand.

[0002]

2. Description of the Related Art In a conventional joystick, a switch is turned on and off as an input signal by tilting the stick back and forth and left and right with a hand. Further, the encoder is linked to the movement of the stick to capture the finer movement of the stick as an input signal. In any case, it is assumed that the operation is performed by hand.

[0003]

When a person with a physical disability or a healthy person cannot use his hands,
Or, it is used in a device in which a hand is intentionally disabled or not operated.

[0004]

SUMMARY OF THE INVENTION There are several physiological factors that change due to human emotions. By measuring one or more physiological elements among them, collecting them collectively, and performing statistical data processing, it was demonstrated that they can be classified into several categories corresponding to emotions.

[0005] By associating the category with the operation direction of the joystick, a joystick that does not depend on the hand operation has become possible.

[0006] Among physiological factors that change due to human emotions, the state of brain waves and the change in heart rate appear clearly. Θ wave and α wave in brain wave corresponding to emotion category
It was experimentally confirmed that there was a remarkable difference between the strength patterns of the wave and the β wave. Above all, the intensity of the β wave is strongly correlated with the emotion category. The difference between the patterns is made to correspond to the operation direction of the joystick.

FIG . 1 shows the configuration of the present invention. Biological information is detected from each part of the human body by the sensor 1, the information is united by the information collecting unit 2, and impedance conversion of a signal and further removal of noise are performed. The data processing unit 3 performs statistical processing of data and performs category classification. Based on the result of the category, the joystick driver 4 outputs a joystick output.

In the second aspect, the function of the first aspect is performed by taking brain waves and heart rates as biological information.

According to a third aspect of the present invention, as the biological information, the strong and weak patterns of the θ wave, α wave, and β wave in the brain wave are
It is an element of category classification.

[00010]

According to the present invention, a joystick that does not depend on the operation of a hand can be used, so that a person with a physical disability or a healthy person cannot use a hand or intentionally cannot use or use a hand. It is now possible to operate with no condition. .

Claims (3)

[Claims] 1. A joystick that functions based on the result of measuring physiological elements that change due to human emotions, collecting them collectively, and performing statistical data processing. 2. The joystick according to claim 1, wherein brain waves and heart rates that greatly change due to emotions are measured, collectively collected, and function based on the result of statistical data processing. 3. The joystick according to claim 1, wherein the joystick functions by measuring a β wave in an electroencephalogram that changes greatly due to emotion and performing statistical data processing.
