It is really heartening to listen about that a person can even control his computer without using a mouse and controller. The researchers at Microsoft has come up with patent for a device that has to be a music based control scheme where hand jesters can be used as to employ and run over things like simple MP3 player while jogging or either open car’s trunk, remotely. In order to reach out and desire these tasks a system that is called Electromyogrpahy, or EMG has been used.

Under this technology electrodes has been used over arms, legs, head and chest to track muscle movements as keyed to specific actions and commands as sent to computer, video game system, vehicle or any other device provided for having “hands-free” control scheme.
