Eye-Gaze-Controlled Wheelchair System with Virtual Keyboard for Disabled Person Using Raspberry Pi

Abstract

Eye-gaze technology enables people to operate a system by gazing at instructions on a screen. It can assist paralyzed people who are unable to communicate with others due to their inability to speak or use their muscles well enough to write on paper or type on a keyboard. So, this paper presented an eye-gaze-driven wheelchair with a virtual keyboard for paralyzed people. The main aim was to make it easier for individuals with impairments to use wheelchairs and type on a keyboard, as well as to eliminate the need for assistance for the impaired person. The system integrates an eye-controlled wheelchair with a virtual keyboard using a low-cost system. In this system, the wheelchair was controlled by eye movement and the virtual keyboard was controlled by eye blinking. The camera was positioned in front of the disabled person to take real-time images and track eye movement. The wheelchair travels left, right, and forward according to eye movement. The whole system was controlled by a Raspberry Pi.
