Schematics of a collider-based movement detection algorithm. The IMUs measure human kinematics and colliders are computed and checked for exceeding bounds. If a collider is activated within a set time detection window, t, its ID is added to a hash chain. The process repeats until no more activations occur within the time detection window, signaling the end of the chain. The completed chain is then sent to check the matching in the predefined hash table to identify the movement.
