Non-Intrusive Head Movement Control for Powered Wheelchairs

While joysticks are commonly used to control wheelchairs, they may not be suitable for individuals with severe disabilities such as quadriplegia. Existing solutions like headrest switches, sip-and- puff devices, or tongue drive systems have limitations in terms of usability and control. This study explores a non-intrusive head movement control system for powered wheelchairs, aiming to improve mobility for people with motor impairments. Using head movement tracking technology, the system interprets gestures and translates them into wheelchair commands. Experimental trials and user feedback demonstrate the system’s effectiveness and positive user experience, indicating its potential as a practical assistive technology tool for enhancing wheelchair maneuverability and user autonomy.
