Amusement system based on an optical instrumentation method for the living body
First Claim
1. An amusement system using an optical instrumentation method for the living body comprising at least one light illumination device for irradiating the subject with light, at least one light detector which condenses the transmitted light irradiated by the light illumination device and propagated through the living body, a display unit provided with a screen which displays at least one object, and a computing part which controls the display unit based on a measurement signal related to the intensity of the transmitted light measured by said light detector, wherein a state comprising at least one of said objects displayed on said screen varies according to the intensity variation of the signal measured by said one or more light detectors.

Abstract
An amusement system is provided wherein a variation of light intensity transmitted through a living body which reflects a metabolite concentration or concentration variation in the living body reflecting a mental state or brain activity, is measured, and the measurement result is reflected in an object displayed on a screen. By bringing a light illumination device and light detector in contact with the skin of a subject, the intensity of the light propagated in the subject is detected, and the detection result is transmitted to an electronic calculator. The position, shape or color of the object displayed on the screen is made to vary according to the variation of this detected intensity. Thus, human thought can be measured and the state of the object on the screen controlled without using an existing input device such as a mouse, joystick or handle.
