While bored, we found ourselves spinning our phones in our hands. Why not turn it into an a game?
We conceptualized and developed a method for detecting flips on an android phone. The phone actually has to be "flipped" not just turned. We spent time analyzing the data and writing classifiers to ensure the flip detector is robust to attempts to generate fake flips.
After creating the flip detector, we created a short mini-game where the user attempts to achieve a high score by flipping their phone as many times in one toss. A future mini game would be F.L.I.P. (like H.O.R.S.E. in basketball), where you challenge your friends to match a specific flip combination.
