Title: Development of a low-cost, portable, tablet-based eye tracking system for children with impairments
Abstract: Eye tracking technology can enable children with severe speech and motor impairment to communicate. Eye tracking systems for the use of human computer interaction have long been an area of interest in the assistive technology field. However, a number of factors have prevented eye tracking from being an accessible technology, including the invasiveness, robustness, availability, and cost of eye tracking systems. Moreover, a common drawback of some commercial eye tracking systems is that head motion is not typically considered, and many systems are not portable or mobile.
This work describes the design and development of an eye tracking system for children with disabilities. The system is an economical alternative to commercially available devices. It does not require any sophisticated hardware, and is tablet-based. It uses raw images from a webcam and relies on distinct features of the eye that can be detected and tracked using image processing functions. The simple eye tracking system can differentiate between 16 different points of gaze enabling the user to have access to 16 options on a 4 by 4 display.
