Fair Dice: A Tilt and Motion-Aware Cube with a Conscience

Abstract

As an example of sensory augmentation of a tiny object, a small cube-sized die is presented that perceives rolls and records what face it lands on. It is thus able to detect bias for unfair behaviour due to its physical imperfections. On a deeper level, this case study demonstrates the integration of energy-efficient sensor fusion, combination of classifiers, and a wireless interface to adaptive classification heuristics.
