Figure 1. We explore the use of text-based stimuli to enable gaze interaction with public displays using the Pursuits technique [47]. Motivated by the fact that much of the content on large displays is text, we investigate two use cases: (a) Users can spontaneously interact with text-based content without calibration. A sample application could be a survey where answers in the form of text are selected by reading them (left). (b) An eye tracker can be calibrated implicitly as users read text on the screen (right). After calibration, fine-grained information on the user's gaze point are obtained. ABSTRACTIn this paper we show how reading text on large display can be used to enable gaze interaction in public space. Our research is motivated by the fact that much of the content on public displays includes text. Hence, researchers and practitioners could greatly benefit from users being able to spontaneously interact as well as to implicitly calibrate an eye tracker while simply reading this text. In particular, we adapt Pursuits, a technique that correlates users' eye movements with moving on-screen targets. While prior work used abstract objects or dots as targets, we explore the use of Pursuits with text (read-and-pursue). Thereby we address the challenge that eye movements performed while reading interfere with the pursuit movements. Results from two user studies (N=37) show that Pursuits with text is feasible and can achieve similar accuracy as non text-based pursuit approaches. While calibration is less accurate, it integrates smoothly with reading and allows areas of the display the user is looking at to be identified.
