EOG based wheelchair control for quadriplegics

Quadriplegics is paralysis caused by illness or injury to a human that results in the partial or total loss of all their limbs and torso. Quadriplegics is highly dependent on an assistant for wheelchair movement. It is not always the case where the helper is with the patient all the time, therefore independence is encouraged among the wheelchair users. The eye movement can be considered as a significant communication tool for tetraplegia. The signal from the eye muscles, called electrooculogram is generated due to different eye movements, directions and levels. The signal strength for various eye movements are obtained using EOG electrodes. So it has been proposed to control the wheelchair of physically handicapped people with their eye movements.
