PURPOSE: An operation recognition based on a physical model is provided to supply a general framework for operation recognition without depending on complex statistical analysis. CONSTITUTION: A simulated physical object is generated(802). A mobile device receives sensor data reacting to the detected operation. The sensor data include power or impact. The power or impact is applied to a physical object(804). The simulated physical object state is observed(806). Input about an application is supplied based on the observed state(808).
