How to use mobile devices as input devices for multi-player interaction in a copresent game on big screens with a low barrier to entry?

Details

With Glowshrooms, we wanted to create a game that multiple people could interact with using their phones, with a goal of minimizing churn (and maximizing fun!).

Most people already contain a device in their pockets that provides rich sensor data, so we wanted to utilize this in an engaging interactive experience.

We succeeded by implementing a quick onboarding via QR code - no app downloads required.
