For blind athletes, it is impossible to perfect technique by observing the movements of others. Trainers must guide the athlete by directly moving his/her body parts to enable muscle memory. Recently, PhysOrg has collaborated with researchers at Imperial College London to develop the Ghost system for blind athletes. The system is a vibrational feedback device that trainers can program with waypoints to guide the user through each step of a correct movement. The trainer only has to program the device once and the athlete is able to repeatedly practice the specific movements while Ghost monitors accuracy by using vibrations and audio cues. Users can also import motion recordings from star athletes to help improve technique. In the future, researchers hope to use the technology to help stroke patients or those recovering from other neurological conditions.
