Alternative Communication Device For Stroke People

Abstract

Adults with acquired neurological disorders (stroke, Traumatic Brain Injury ...) develop their disability for verbal communication and literacy capabilities as typical speakers and writers. Depending upon their neurological condition, they gradually or suddenly lose their speech or language capabilities and are required to rely on Alternative Communication systems(ACS) to meet their communication needs. This technology offer valuable opportunities to people with physical disabilities. The attractive features of this system include noninvasive signal recording, little training requirement, and a high information transfer rate. This project presents the design and development of a system that brings out a disabled person from the condition of prisoner in his own body. Stroke is one of the main causes of disability in the world. About 20% of stroke patients experience aphasia, with 20-30% of these individuals exhibiting severe communication deficits for at least a portion of their recovery period. Alternative Communication (ACS) encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production of spoken.
