For my Master’s Thesis I created a location-based mobile game that aims to motivate citizens to actively participate and discuss urban topics. In the game Community Circles citizen create geo-referenced contributions (ideas, issues, opinions & polls). Each contribution has an impact area that grows with its activity and can merge into communities. Further, each contribution has a lifetime, which can be extended due to the activity. The long-term goal is to grow and keep communities alive.
The game prototype consisted of a functional hybrid mobile app and a backend server. The concept was evaluated during a game trial involving real users. Following are some screenshots of the app:
In the video below you can see a demo of the game concept. It shows the dynamic evolving of contributions and communities. This demo was written in Processing.
