Building a system and app to showcase some really cool possibilities when using two eye trackers. Together, users can search hotels on a large map – both their gaze is indicated, in order to improve the user’s teamwork.

In this demo we present a gaze aware display that dynamically adapts its content to two users’ interests and attention simultaneously. Prior gaze-interactive systems can only support a single user and require tedious isolated calibration procedures for each usage. We developed a system that allows multiple people to walk up to a large gaze-interactive display that can sense their interests and current focus of attention. For demonstration, we built a tourist map application that first implicitly calibrates users, and then reveals additional information when users look at destinations of interests.
