Eye Tracking Methodology : Theory and Practice

Despite the availability of cheap, fast, accurate and usable eye trackers, there is still little information available on how to develop, implement and use these systems. This second edition of Andrew Duchowskis successful guide to these systems contains significant additional material on the topic and fills this gap in the market with this accessible and comprehensive introduction. Opening with useful background information, including an introduction to the human visual system and key issues in visual perception and eye movement, the second part surveys eye-tracking devices and provides a detailed introduction to the technical requirements necessary for installing a system and developing an application program. The book focuses on video-based, corneal-reflection eye trackers - the most widely available and affordable type of system, before closing with a look at a number of interesting and challenging applications in human factors, collaborative systems, virtual reality, marketing and advertising.
