A French researcher has built a device allowing disabled people to write or draw on a computer screen using only their eyes, a report said Thursday.
With head-mounted cameras monitoring their eye movements, test subjects were able to write and draw on a blank computer screen in the latest breakthrough for people trapped in immobility by disease or accident.
"For persons deprived of limb movement, this offers a fast, creative and personal means of linguistic and emotional expression," said the report by Jean Lorenceau of France's CNRS research institute.
Lorenceau's system, still just a prototype, compensates for saccadic, or jumpy, eye movements to allow a smooth writing style.
After four half-hour training sessions, his subjects were able to write at a rate of about 25 letters per minute.
Similar systems exist, but none that allow a person to trace their own letters with this level of precision.
In July, engineers said they had built a device using mass-produced video gaming equipment that lets disabled people control a computer cursor with just their eyes -- with a price tag of under $30 (25 euros).
Other technologies require electrode implants in the brain, an expensive procedure.
Such technology offers hope for restoring some level of independence to people suffering from multiple sclerosis, Parkinson's disease, muscular dystrophy and spinal cord injuries or amputees.
In the EU alone, there were more than 16 million people with disabilities who would benefit from such a system, an earlier study had found.
