1. A system comprising: a detection and tracking algorithm running on a processor that is coupled to a sensor, wherein the detection and tracking algorithm is coupled to a gestural interface; a gestural interface application running on a processor that is coupled to a sensor, the gestural interface application receiving data from the sensor corresponding to an object detected by the sensor, generating images from each frame of the data, wherein the images represent a plurality of resolutions, detecting blobs in the images and tracking the object by associating the blobs with tracks of the object, detecting a pose of the object by classifying each blob as corresponding to one of a plurality of object shapes, and generating a gesture signal in response to the pose and the tracks and controlling a component coupled to the interface system with the gesture signal.
