Key Hunter is a prototype of a modern location-based key hunting game with competitive game elements utilizing novel beacon technologies. It was developed with Ionic and the Estimote SDK PhoneGap Plugin. This game prototype resulted from the course “Exploring Disruptive Technologies” at the Vienna University of Technology as a team-project. This lecture’s theme was focused on beacon technologies (e.g. Apple’s iBeacon) and how to utilize this technology in novel and unusual ways.
