Patients without the ability to use their limbs may have a new way to communicate, thanks to researchers in France. This offers hope to sufferers of strokes, spinal injuries, or degenerative diseases such as ALS, or Lou Gehrig's disease, who may be left without the ability to type, pick up a pen, or even speak.
The researchers developed a system that allows users to write in cursive on a video monitor using only their eyes. Dr. Jean Lorenceau of the Universite Pierre et Marie Curie in Paris has developed a method for translating eye movements into writing on a screen, and by doing so has simultaneously advanced possibilities for patients and solved a tricky puzzle posed by biology. The results are in today's issue of the journal Current Biology.
