A pair of engineers at the Applied Physics Laboratory’s (APL) National Security Technology Department at John Hopkins University are using Activision's Guitar Hero III: Legends of Rock for Nintendo Wii as part of their work in developing an innovative prosthetic arm. Bobby Armiger and Jacob Vogelstein have rewired the game’s controller giving amputees a chance to rock out while testing out their latest prosthetic prototypes.
Their work has led to the creation of two prototypes and a surgical technique that reroutes nerves that once controlled a patient’s arm to the muscles that remain. The signals sent from the reattached nerves are picked up through the skin to control the prosthetic arm. But for those signals to be recognized, they must first be identified properly. More...
This detection process is similar to training voice-recognition software but rather than analyzing tones, the APL system records and classifies muscle twitches. Traditional methods of calibrating mechanical limbs to recognize and respond properly to electrical signals in residual muscles are an exhausting and draining process, explains Armiger. That is where Guitar Hero comes in.
