Smartphone Eyetracking

Our Caltech team (led by Na Yeon Kim), partnered with Google Resesarch, and conducted a proof-of-concept study that investigated social attention in autism using a smartphone eye-tracking technology.

We showed participants natural scene images and short YouTube videos, while measuring their eye movements from a screen-based eye-tracker and a smartphone eye-tracker.

We found consistent results measured between the screen-based and smartphone eye-trackers. Autistic participants are more likely to focus on nonsocial aspects of the video, such as objects or background patterns, while neurotypical subjects focus more on social aspects, such as people’s faces.
