Abstract: A biosignal-based avatar control system according to an embodiment of the present disclosure includes an avatar generating unit that generates a user's avatar in a virtual reality environment, a biosignal measuring unit that measures the user's biosignal using a sensor, a command determining unit that determines the user's command based on the measured biosignal, an avatar control unit that controls the avatar to perform the command, an output unit that outputs an image of the avatar in real-time, and a protocol generating unit for generating a protocol that provides predetermined tasks, and determines if the avatar performed the predetermined tasks. According to an embodiment of the present disclosure, it is possible to provide feedback in real-time by understanding the user's intention through analysis of biosignals and controlling the user's avatar in a virtual reality environment, thereby improving the user's brain function and motor function.

Abstract: The training apparatus according to an embodiment includes: a support unit; a guide unit fixed on the support unit and including rails which extend in a front-rear direction; a sliding unit which is movable in the front-rear direction along the rails of the guide unit; a pillar-shaped rotation axis fixed on the support unit; a footrest unit which supports a user's foot; a lower support formed below the footrest unit; and a connection rotating unit formed below the footrest unit and connected to the rotation axis of the support unit through insertion to allow the footrest unit to rotate around the rotation axis. A plurality of springs installed inward from two sidewalls of the sliding unit is configured to come into contact with the lower support of the footrest unit and apply pressure from two sides when the footrest unit rotates.
