Wheelchair-bound can navigate via tongue piercing Dec 1st 2013, 20:35, by Sam Shead, Techworld.com Researchers have demonstrated that it's possible for someone to navigate a computer or steer a wheelchair with a tongue piercing and a few sensors. The team at Georgia Institute of Technology in Atlanta showed that the movement of a tiny magnet in a tongue piercing can be detected by sensors and converted into commands, which can control a range of devices. Navigating by tiny joystick The Tongue Drive System (TDS) allows the user to use their tongue like a joystick once it has been pierced with a barbell-shaped titanium piercing. This piercing is embedded with a high-strength magnet and its location within the mouth is recognized by four sensors mounted on a headset, two of which are placed on slim arms beside each cheek. The sensors then wirelessly transmit data to an iPod with an app that has been developed to convert various tongue movements into instructions for the device that the user wants to control, such as a wheelchair.
