Physical Feedback in Virtual Rehabilitation System Using Vibration Motor

Abstract

It is useful for patients and therapists to undergo rehabilitation using techniques such as Virtual Reality(VR). This study aims at the improvement of arm function by adding sense of touch information to sight information to be provided in VR. As a method, this study obtained feedback information by sense of touch using Leap Motion Controller, Unity, KKHMF UNO R3 and vibration motors. The vibration motors are attached to each real finger-tip to obtain the sense information of touch of the finger in projected virtual space. When the system recognized that subjects contact with an object in the virtual space, the system made the vibration motors activate. A comparison experiments with and without the vibration motor was to test it and investigated how feedback information affected it.
