Electric wheelchairs are designed to aid paraplegics. Unfortunately, these cannot be used by persons with higher degree of impairment, such as quadriplegics, i.e. persons that, due to age or illness, cannot move any of the body parts, except of the head. Target of this project is to develop a solution able to move the wheelchair by the movement of the head. With an accelerometer which is placed on a cap, which is worn by the patient, it’s possible to obtain the head motion recognition. By means of the accelerometer data processing, stepper motors are controlled in order to move the joystick of an electric wheelchairs.
