Abstract

Assistive technology is taken one step ahead with the introduction of sophisticated eye-tracking and gaze-tracking techniques which track the movement of the eye and the gaze location to control various applications. This paper describes in detail the low-cost hardware development and the software architecture for a real-time eye-tracking based wireless control system using the open-source image processing framework of AForge.NET. The system developed has been tested in the field of remote robotic navigation, using the Lego NXT Mindstorm robot, and wireless home automation, using the X10 transmission protocol. The system designed uses a wireless camera to detect the eye movements and transmit control signals over a wireless channel. This provides a highly useful alternative control system for a person suffering from quadriplegia i.e. full body paralysis. Tests conducted to measure the processing time, system accuracy and error aid in evaluating the performance of the developed eye-tracking system.
