Motion Karaoke is an interactive toy that allows players to recored body-movements, challenging each other to repeat them as precisely as possible. The game can be played regardless of age or most forms of impairment.

Built on a MicroPython system, the device tracks 3d-motion using an accelerometer and translates it to light and haptic feedback in real time.

Core of the system is a MicroPython Pyboard and its accelerometer. The toy records a movement by storing the accelerometer-data and compares two movements by processing the two arrays with a series of algorithms, checking the similarity.
