How To Build A Low-Cost Eye-Tracking System

Eye tracking, previously the purview of well-funded laboratories, is now available to any individual who wishes to study gaze patterns. Advances in eye-tracking technology have made it possible for those with meager budgets but an abundance of motivation to engage in studies that examine participants\u27 eye movements and fixations. This article presents a how-to guide for creating low-cost eye-tracking solutions and includes discussion of optical hardware, tracking software, and data analysis programs. The wider availability of eye-tracking technology ensures that the broader scientific community has access to techniques that can inform design and enhance research. © 2012 Human Factors and Ergonomics Society
