Eighteen ALS patients will be trained to control a new communication device (Eye On Line: EOL) that permit over smooth eye movements to generate digits, letters, words or drawing at will. The intervention consists in a training program during six visits over 3 weeks on site allowing a gradual acquisition of the eye-writing. The primary objective of the study is to assess the feasibility of the use of EOL device in ALS patients. The EOL device potentially offers a creative and personal means of linguistic and emotional expression in subject with motor disability.
