Eye-writing Tech May Help People with Limiting Conditions Communicate Freely

Researchers at Université Pierre et Marie Curie in Paris have made a new discovery that may help people use eye movements to draw and write in cursive. The technology is described in a paper published recently in the online publication Current Biology.

“Contrary to the current belief, we show that one can gain complete, voluntary control over smooth pursuit eye movements. The discovery also provides a tool to use smooth pursuit eye movements as a pencil to draw, write, or generate a signature.”

According to the researchers, the eye-writing technology could make communication easier for people with Lou Gehrig’s disease or other conditions where arm and leg movement capabilities have been lost.

The technology may also help to improve eye movement for those with conditions such as ADHD or dyslexia, the researchers say. In addition, it could prove useful for helping surgeons or athletes to strengthen eye-based skills needed in such professions.
