This input device is provided with an image acquisition unit (151) which acquires images captured of a body moving by a user's volition, a motion trajectory extraction unit (152) which, from the trajectory followed by the body, extracts multiple continuous motion trajectories fitting pre-stored motion patterns, a relative information acquisition unit (153) which acquires relative information indicating the relation between the multiple motion trajectories, and an input determination unit (154) which determines the user's input to a device on the basis of the relative information. |
