EYE POTENTIAL DETECTION DEVICE, EYE POTENTIAL DETECTION METHOD, EYEWEAR AND FRAME

摘要

PROBLEM TO BE SOLVED: To detect eye potential as large as possible and easily respond to eye movement detection with high accuracy.;SOLUTION: A minimum of four EOG electrodes in the periphery of both eyes of a user is disposed as follows. First, two electrodes of the left eye side (152a, 152b) and two electrodes of the right eye side (151a, 151b) are disposed in the line symmetry to the line drawn in the vertical direction (e.g., the line along a user's nose ridge) from a center point of the line for connecting the center of both left and right eyes. Two electrodes (152a, 151a) of the upper side and two electrodes (152b, 151b) of the lower side from a line for connecting the center of both left and right eyes are disposed by avoiding a left predetermined range (AXL) comprising an inflection region where the detection polarity of the eye potential is changed when straddling the perpendicular passing a left eye center position (P1) to the left or right, and a right predetermined range (AXL) comprising an inflection region where the detection polarity of the eye potential is changed when straddling the perpendicular passing a right eye center position (P2) to the left or right.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
