Title:
VIRTUAL REALITY GAME- AND BIOSIGNAL SENSOR-BASED VESTIBULO-OCULAR REFLEX ASSESSMENT AND REHABILITATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/262973
Kind Code:
A2
Abstract:
The present invention relates to a virtual reality-based vestibulo-ocular reflex (VOR) assessment and rehabilitation apparatus. The virtual reality game- and biosignal sensor-based VOR assessment and rehabilitation apparatus may comprise: a biosignal sensing unit which senses and notifies of head movement and eye movement of a patient using an eye tracker and an inertial measurement unit (IMU) sensor attached or installed to a head-mounted display device; a VOR function assessment unit which, when a VOR function assessment is requested, configures and provides a game for VOR function assessment, and then obtains a VOR gain by calculating and quantifying the ratio of eye to head movement from the sensing result of the IMU sensor and the eye tracker; a patient-personalization control unit which, when rehabilitation exercise is requested, determines, on the basis of the VOR gain of the patient, the types and order of rehabilitation games, and a rehabilitation level; and a rehabilitation game providing unit which, according to the types and order of the rehabilitation games, configures and provides games for at least one among smooth pursuit, saccades, VOR rehabilitation exercise, amplified VOR rehabilitation exercise and suppressive VOR rehabilitation exercise, and determines the difficulty levels of the games on the basis of the rehabilitation level.
