The dr. Jean Lorenceau, University Pierre and Marie Curie in Paris, has developed a device by which the movements of our eyes can be used as a way of writing.
This product was not developed earlier because of a simple cause: lack of technology. The human eye produces many involuntary movements, and these to be interpreted by the device became anything but writing desired. With some new developments, dr. Lorenceau been able to use an optical illusion called "reverse-phi motion" which was widely studied last year. Finally, with the addition of this illusion to the system, it was possible to monitor the voluntary movements of the human eye.
Lorenceau says that with practice 90 minutes a person can use the system to write about 20 characters per minute. Yes, there is a great speed, but for many people with various disabilities, is a new form of expression. In addition to letters, you can also use the system to write numbers and drawings.
