Head Motion Controlled Wheelchair for Physically Disabled People

Abstract

Physically disabled people face difficulties in daily life because of their body impairment from their birth or due to an accident or illness. The project’s goal is to design a wheelchair that could function for a disable-person who cannot move other parts of the body correctly, keeping their words in mind with the help of head movements. Medical equipment manufactured to assist disabled peoples are very complicated, limited, and costly. A head motion controlled wheelchair is an intelligent wheelchair with facilities for navigating, recognizing obstacles, and moving automatically by managing detectors and motions. The prototype of the wheelchair performs head motion through a microcontroller. Furthermore, data processing is performed with the help of an accelerometer. The controller filters the indication and allows the action of the wheelchair for its navigation. The ultrasound detector helps to resist impediments. Usually, it is expensive, but we have designed it at an inadequate cost so that ordinary people from underdeveloped or developing countries can use it. The system memorizes the head gesture for further referencing it as the stable gesture or “neutral position” after identifying the start signal. The dc motors will drive the wheelchair during the gesture of control mode. The motors will not work, and consequently, the wheelchair will not run when the head is neutral.
