A web app reads the phone accelerometer via the device motion event, segments gestures by a threshold chosen from user tests (about 16–17 m/s²), and classifies motion sequences with K‑NN + Dynamic Time Warping as the distance metric. The demo maps left/right/up/down gestures to on‑screen arrows in real time, implemented in JavaScript, and the pipeline (segmentation → DTW distances → K‑NN) proves robust enough to control a simple game.
