- 摘要：
PROBLEM TO BE SOLVED: To implement mouse cursor control using ocular potential.
SOLUTION: A power noise component is removed from each of digital values corresponding to a first ocular potential signal detected by a pair of electrodes placed above and below an eyeball and a second ocular potential signal detected by a pair of electrodes placed to the left and right of the eyeball. A difference is then calculated between each of the digital values corresponding to the first and second ocular potential signals and a calibration value corresponding to the digital value. The direction of movement of the line of sight on a display screen is next identified by the result of comparison of each calculated difference with a threshold of directional change corresponding to the ocular potential signal, and a mouse cursor is moved by a set distance in the identified direction.
