Eye tracking and universal access: Three applications and practical examples

Abstract

The human eye is an essential component in the communication between computers and their operators. For this reason, eye tracking technology provides a valuable perspective into HCI. This paper discusses three applications of eye tracking technology to the challenge of universal access. The first is the use of gaze-controlled systems that allow disabled users to operate computers and other modern technology. The second is the use of eye tracking as a research methodology to be used in designing interfaces that help to bridge the digital divide. The third is the use of eye data to examine cognitive attributes (i.e., workload, fatigue, etc.) of operators of complex systems as they complete critical tasks. Practical examples of each of the three applications are provided. © 2011 Springer-Verlag.
