Augmentative Alternative Communication using Eyelid Movement Remote Detection by Speckle Patterns Tracking System for Amyotrophic Lateral Sclerosis Disease

Not Accessible

Your library or personal account may give you access

Abstract

The implementation of augmentative alternative communication optical device for ALS speech problem is presented. The sensor is based on temporal tracking of back-reflected secondary speckle patterns generated when illuminating an eyelid with a laser.
