Seeing Stars – Bespoke AR for Mobiles


We’ll explore the development of the Fireballs in the Sky app, designed for citizen scientists to record sightings of meteorites (“fireballs”) in the night sky. We’ll introduce the maths for AR on a mobile device, using the various sensors, and we’ll throw in some celestial mechanics for good measure.

We’ll discuss the prototyping approach in Processing. We’ll describe the iOS implementation, including: libraries, performance tuning, and testing. We’ll then do the same for the Android implementation. Or maybe the other way around…
