<p>PROBLEM TO BE SOLVED: To provide a game machine which measures the density of a metabolite in a living body reflecting a mental state and brain activity and the change in optical intensity transmitted through the living body reflecting the change of the density and reflects the result in measurement to an object displayed on a screen. SOLUTION: By bringing optical illuminators (1-1), (1-2) and a photodetector (1-5) into contact with the skin of a patient (1-3), the optical intensity propagated through the inside of the patient is detected and the result in detection is sent to a computer (1-8). Then, in accordance with the change in the detected optical intensity, the position, shape and color of the object displayed on the screen (1-9) are changed. It is possible to control the state of the object on the screen directly by measuring what is thought by a person without using an existent input device represented by a mouse, a joy stick, a handle, or the like.</p> |
