Abstract:
A method of pre-caching user interaction elements, which comprises:monitoring motion patterns 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; providing one or more control areas at the writing surface; analyzing the monitored motion patterns made while the recorder is off the writing surface to determine if the recorder is approaching the writing surface; when it is determined that the recorder is approaching the writing surface, defining a plurality of trajectories between the recorder and each of the one or more control areas based upon the location and movement of the recorder off the writing surface; monitoring an actual trajectory of the recorder; correlating the plurality of trajectories with the actual trajectory; and for one of the plurality of trajectories with a highest degree of correlation, defining a corresponding control area as at least one target area, the at least one target area having an associated functionality; and triggering at least one aspect of the functionality before contact between the recorder and the at least one target area.
