Since its inception, eye tracking has been employed by cognitive scientists to study reading, learning, attention, and neurology; by marketers to examine the effectiveness of ad and package designs; and by human factors engineers to guide automotive and airplane cockpit design. These and other disciplines have had great success leveraging eye tracking as a behavioral research method and to inform the design of communications and interactions. Recently, as eye tracking technology has become more affordable and accessible, academics, research suppliers, and eye tracking equipment makers have been experimenting with applying eye tracking to behavioral research in new domains.
