ANALYSIS SYSTEM, ANALYSIS METHOD, ANALYTIC DATA ACQUISITION DEVICE, AND ANALYTIC PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/138767
Kind Code:
A1
Abstract:
Provided is an analysis system for analyzing the function of semicircular canals by rotational stimulation, the analysis system having a vestibulo-ocular reflex data acquisition unit for acquiring first vestibulo-ocular reflex data obtained by dividing the vestibulo-ocular reflex rotation angle amount by the rotation angle amount of the head position, and second vestibulo-ocular reflex data obtained by dividing a remaining rotation angle amount, which is a difference obtained by subtracting at least the rotation angle amount based on compensatory eye movement (CUS) from the rotation angle amount of the head position, by the rotation angle amount of the head position. The analysis system analyzes the function of the semicircular canals on the basis of the second vestibulo-ocular reflex data, or on the basis of the first vestibulo-ocular reflex data and the second vestibulo-ocular reflex data.
