Smart Wheel Chair for Quadriplegics

quadriplegia is paralysis where the person is unable to move all his limbs. The primary cause of quadriplegia is a spinal cord injury, but other conditions such as cerebral palsy and strokes can cause a similar paralysis. The amount of impairment resulting from a spinal cord injury depends on the part of the spinal cord injured and the amount of damage done. Injury to the spinal cord can be devastating because the spinal cord and the brain are the main parts of the central nervous system, which sends messages throughout your body. This paper proposes algorithm to detect the eye movement, known as Coherence algorithm. The proposed paper uses eye to control the wheel chair. The Coherence algorithm detects whether it is the movement of eye towards left or right. The eye blinking feature is also used by the algorithm to control the starting and stopping of wheelchair, then a heart beat sensor is used to detect the heart beat values, Whenever the heart beat values crosses a threshold value, then a buzzer is activated and a call is made to the concerned person using GSM.
