Remote control system with teeth

Japanese scientists say they have developed a remote control system that identifies jaw movements to make simple commands for a music player or other electronic devices. The system is a headset or a device mounted on a rim.

"We can give orders without using our hands ," said Fumio Miyazaki, Osaka University's lead researcher. Infrared sensors identify the movements on the temples when the user opens or closes the mouth and turns the signal into a command.

In order for the device to understand the command, the jaw movement should last about 1 second to distinguish movements when speaking, eating or chewing gum.

This system allows you to order a music player or cell phone without using your hands in a crowded train, as well as helping disabled people to operate the wheelchair. It can also become a new interface for computers instead of the mouse to surf the web.
