Method, device and system for rehabilitating cognitive function by using virtual object model

Abstract

The present disclosure relates to a method by which a device provides a service so as to enable cognitive function rehabilitation by using a virtual object model. The method includes the steps of: generating first preliminary stimuli for identifying egocentric neglect in a visual range of a subject; obtaining first reaction information about the first preliminary stimuli; determining an egocentric cognition range in which the subject can egocentrically recognize visual stimuli; sequentially generating second preliminary stimuli for identifying allocentric neglect in the egocentric cognition range; obtaining second reaction information about the second preliminary stimuli; determining an allocentric cognition range in which the subject can allocentrically recognize visual stimuli; generating input stimuli for the subject in consideration of the egocentric cognition range and the allocentric cognition range; and obtaining third reaction information, according to a predetermined reaction operation of the subject, for the input stimuli.
