Tongue-Drive to Help the Disabled Take Control of Technology

A group of researchers have developed an experimental tongue-based system that may allow people with debilitating disabilities control wheelchairs, computers and other devices with relative ease.

Electrical engineer Maysam Ghovanloo developed the Tongue Drive system in collaboration with graduate student Xueliang Huo.

Oral Cancer | Mouth Cancer - Types, Causes, Symptoms, Diagnosis, Treatment & Prevention
Oral cancer is a cancer that develops in any part of the mouth. It is more common in men over 40.

Since the tongue is directly connected to the brain via cranial nerves, it usually remains mobile when other body parts lose function to disease or accidents.

That mobility underlies the new system, which may one day provide greater flexibility and simplicity to individuals who would otherwise use sip-and-puff controls or brain implants.

The findings have been presented on June 29 at the 2008 Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) Annual Conference in Washington, D.C.

Developmental Disturbances of the Tongue
Tongue is the only muscle that is attached to only one end. The abnormalities of the tongue include tongue disease, tongue tie and size-related anomalies.

"Tongue Drive is inherently wireless and touch-free because it relies on a tiny magnetic tracer attached to the tongue with no power consumption," said Ghovanloo.

"Tongue movements are also fast, accurate and do not require much thinking, concentration or effort," added Ghovanloo.
