Head Motion Controlled Mouse With Home Appliance Control For Quadriplegic Patient

People with severe disabilities often struggle to interact with home devices, making even basic tasks difficult or impossible due to their physical limitations. The Human Computer and human Gesture Interface System is a lightweight wearable prototype that uses head movements for cursor control and cheek muscle twitches for clicks and appliance control, specifically designed to aid individuals with quadriplegia. Quadriplegia is a spinal cord injury which turns to paralysis of the whole body at least the shoulders down which is a great barrier. This paper proposes a prototype of human computer and human gesture interface device, using which, a quadriplegic patient can control a computer cursor and home appliances exclusively with head motions and cheek muscle twitches. The proposed system aims to create a hands-free head motion-subjugated device for computer cursor and electrical appliance control by using an accelerometer to read the values created by the patient’s head movement and translate that into mouse cursor movement and flex sensors to detect cheek muscle twitches and translate that into mouse cursor clicks and turn home appliance switches on and off. This study presents the entire process for developing a system prototype, as well as the system’s capabilities and benefits over currently available assistive technology. Those who suffer from arm problems or quadriplegia may find great assistance from this promising technological advancement.
