Trigger Hunter, 2.0 is an iOS augmented-reality game that was designed in Spring 2017 and developed in Fall 2017. The objective for this application is to teach children about their own asthma and how to manage it in a fun and engaging experience. We decided to teach children specifically about the environmental triggers that can cause asthma and can be found in a common household. With the recent development of mobile augmented reality APKs such as ARKit, we decided to integrate this new technology within our game.

We conduct 3 in-lab and one crowd-sourced experiment in the domains of politics and movies. We find mixed results that interaction traces (visual scents of historical interactions) can increase awareness of bias and impact interactive behavior and decision making.

This experiment used Apple's ARKit in conjunction with the AFrame Javascript webVR framework. Using ARKit’s plane detection as an anchor for the VR experience allows users to experience six degrees of freedom using mobile devices without external trackers.
