Eye tracking methodology: theory and practice

Focusing on recent advances in analytical techniques, this third edition of Andrew Duchowski's successful guide has been revised and extended. It includes new chapters on calibration accuracy, precision and correction; advanced eye movement analysis; binocular eye movement analysis; practical gaze analytics; eye movement synthesis. Eye Tracking Methodology opens with useful background information, including an introduction to the human visual system and key issues in visual perception and eye movement. The author then surveys eye-tracking devices and provides a detailed introduction to the technical requirements necessary for installing a system and developing an application program. Modern programming examples (in Python) are included and the author outlines the gaze analytics pipeline, a step-by-step data processing sequence from raw data to statistical analysis. Focusing on the use of modern video-based, corneal-reflection eye trackers - the most widely available and affordable types of systems, Andrew Duchowski takes a look at a number of interesting and challenging applications in human factors, collaborative systems, virtual reality, marketing and advertising. His primary focus is on methodology, and how analysis of eye movements can enhance research and development of anything that is inspected visually. Stefan Robila, reviewing the second edition says, "The book is written in an easy-to-understand language. Given its breadth, it may be most appropriate for scientists and students starting in this field. ... Overall, I found it to be a solid book on a fascinating topic.
