Wireless vibrotactile feedback system for postural response improvement.

This paper presents an evaluation of a real-time wireless body sensor network for the improvement of postural balance response. The system senses body sway using accelerometers and provides vibrotactile feedback to multiple points on the inner forearm, allowing the subject to obtain a clear indication of imbalanced movements within their center of gravity and respective surroundings. The wireless body sensor network is ergonomic, allowing the subject to feel comfortable and experience unconfined movements during its use.
