New device allows disabled people to draw on a computer using only their eyes

• The Raw

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.
