Title:
DEPTH SENSORY PERCEPTION MEASURING INSTRUMENT
Document Type and Number:
Japanese Patent JP3778182
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To objectively and quantitatively measure the generation degree of depth sensory perception of a person under observation by measuring ophthalmography for both eyes.
SOLUTION: The depth sensory perception measuring instrument has an ophthalmography signal processing circuit 3 performing the signal processing of the sensor output of a both-eye ophthalmography measuring sensor 2, saccade removing parts 7 and 8 for removing the saccade components of the processed signal with respect to left and right eyes, a mutual correlation part 10 for calculating the mutual correlation of the speed components of the angles of rotation of left and right eyes from which saccade components are removed and an analyzing part 11 for calculating the volume of a region wherein the mutual correlation value of the speed or acceleration of left and right ophthalmographys are less than a certain value or the area of two-dimensional projection of this region, the mutual correlation of left and right ophthalmographys or the dispersion of left and right ophthalmographys. By this constitution, the generation degree of depth sensory perception of the person under observation is measured.
