From the reviews:
"The book provides an in-depth overview of the science and applications behind eye-tracking. ... To its merit, the content for each chapter is supplemented with further readings sections, which will allow interested readers to delve deeper in one direction or another. 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." (Stefan Robila, ACM Computing Reviews, October 2008)
From the reviews of the second edition:
"The four-part structure enables you to quickly locate material suited to your background and needs; additionally, each chapter concludes with a helpful summary and discussion of further resources. ... the book does offer useful information for those interested in conducting eye tracking studies."
