What will be the effect of different ambience conditions on the accuracy of balance recovery measurements using a camera based system

Making use of an exergame using a camera-based system can result in less falling among stroke patients. Studies showed promising results so such a method could be used in a home environment. This study focuses on what the effect can be of light conditions, background conditions and clothing on balance recovery measurements using a camera-based system. The results of this study show that different ambience conditions will have an effect on balance recovery measurements and should be taken into account when designing a camera-based system that will be used in a home environment. Wearing casual clothing instead of black clothing and having items in the background will increase the accuracy of balance recovery measurements using a camera-based system. However, when the distance between the camera and the participants increases from about 3 meters to 3.3 meters, the accuracy of balance recovery measurements dramatically decreases.
