<p>PURPOSE:To feed a character and a mark with no use of hand and finger by providing a character/mark plate and a device which measures the movements of human eyeballs gazing steadily the desired character on said plate. CONSTITUTION:The 1st eyeball 1b gazes steadily a character/mark plate 7', and the 2nd eyeball 1a which moves in response to the movement of the eyeball 1b is illuminated by a light source 3 via a half mirror 2. The reflected light sent from the eyeball 1a is detected by a 2-dimensional position detector 5 via a lens 4. The position data outputted from the detector 5 is supplied to an arithmetic processing part 8 via a foot switch 10. Then the position data is coded and outputted from the part 8.</p> |
