Eye movement analysis system, the method of operating eye movement diagnostic apparatus and eye movement analysis system

摘要

PROBLEM TO BE SOLVED: To provide an eyeball movement analysis system, an eyeball movement diagnostic device and an eyeball movement analysis method, capable of easily confirming whether or not the movement data of an eyeball can be suitably separated into a gradual phase and a rapid phase.SOLUTION: An eyeball movement analysis system 22 analyzes movement data of an eyeball in a balance function inspection. The eyeball movement analysis system 22 includes: an input part 221; a phase separation part 223; an angle detecting part 224; a distribution calculating part 225; and an output part 226. The phase separation part 223 separates the movement data input from the input part 221 into a gradual phase and a rapid phase in the eyeball movement based on a predetermined threshold. The angle detecting part 224 detects an angle made between a first displacement vector of the eyeball in the gradual phase and a second displacement vector of the eyeball in the rapid phase subsequent to the gradual phase. The distribution calculating part 225 calculates a frequency distribution of angles made between the first displacement vector and the second displacement vector.
