Wheelchair control system for quadriplegics and ocular keyboard

Quadriplegia is a condition caused by a degenerative disease or a sudden condition that causes loss of movement from the neck down. The inactivity of the upper and lower limbs makes it impossible to drive a manual or electric wheelchair, requiring another person to get around. In response to this issue was held a control device integrated in a manual wheelchair. The control system uses electrical signals generated by the human body (specifically on the face) that result in displacement of the wheelchair. Some diseases such as amyotrophic lateral sclerosis (ALS) have the effect of progressive muscle paralysis affecting the muscles related to verbal and written communication, so they are impossible to communicate with their family, for that reason we design an ocular keyboard that allows the user to write through eye movements.
