Abstract

A method (60) of pre-caching user interaction elements, includes monitoring motion patterns (40) with an electronic input device having a gesture recorder and a writing surface using a three-dimensional position of the recorder with respect to the writing surface, analyzing the monitored motion patterns (42) made while the recorder is off the writing surface to determine if the recorder is approaching a target area at the writing surface (44), the target area having an associated functionality, and triggering the functionality (50)before contact between the recorder and the target area. The steps are repeated continuously. The analyzing step (42) determines if the recorder is moving towards the writing surface, and, if so, a two-dimensional location of the recorder with respect to the plane of the writing surface is determined (46) and a trajectory is defined based upon the location and movement of the recorder off the writing surface. A control area disposed at an endpoint of the trajectory is identified (48) as the target area to be triggered. Alternatively, a plurality of trajectories between the recorder and a control area is defined based upon recorder location and movement off the writing surface and correlated with the actual trajectory. For the trajectory with the highest degree of correlation, a corresponding control area is defined as the target area to be triggered. Triggering of multiple control areas can be simultaneous or sequential. The method can be used with a variety of systems including an inductive stylus and tablet system and a radio frequency stylus and tablet system.
