IMPLIMENTATION OF VIRTUAL REALITY IN REHABILITATION

摘要

In the field of rehabilitation providing training motivation (enjoyment) is very important. This paper outlines the employment of VR (Virtual Reality) to increase rehabilitation training motivation. A large scale yet portable semi-immersive 3 dimensional display is placed in front of existing rehabilitation training equipment. The patient wears a pair of polarized glasses (active polarization) and thus interacts with the dynamic scenery (hills and valleys) in a 3 dimensional virtual world. Feedback is provided through a 3D spatial sensor mounted on one of the pedals (in the case of lower limb exercises). By monitoring the patient's speed of operation any variation in speed, particularly slowing down, typically indicating physical fatigue, a form of visual virtual loading is applied by changing the ascent rate on the pathway from ascent (slow progression per cycle - psychologically difficult) to a descent (rapid progression per cycle of patient operation - psychologically easy).
