Will Eye-Tracking Shape the Future of CHI?

Eye Tracking is currently a multidisciplinary field of study. Even though its roots are in Neuroscience and Psychology, nowadays, the field has become of interest for many other types of researchers, from Computer Science to Marketing. While the original applications were focused on the study of attention, visual paths and fixations, at the moment we are seeing how the interest has gravitated towards the interactions.

Using the gaze point as an input method provides a lot of possibilities for novel interactive applications. This approaches to this technology rely most on achieving a consistent relationship between the position of features in our eyes (usually pupil centre of reflections with different types of light) and the point on our visual field that is the target of our gaze, using the point we are looking at as a pointer or an indicator of the user intentions.
Research applications have been proven to be successful, but we have yet to see massive, non-niche commercial applications. Most of the consumer systems that make use of this technology are either aimed to be assistive technologies or in very early stages of development. Nonetheless, the big industry actors are making moves to position themselves in the market, so it is to be expected that, alongside the growth of virtual and augmented reality, this technology will become mainstream in the future.
