Abstract: A method from controlling a computer is disclosed. The method includes receiving position data defining an actual position of a sensed object, applying a first scaling profile to the position data. The first scaling profile includes at least one scaling curve defining a relationship between the actual position relative to a virtual position in a rendered scene within an application program executed on the computer. The scaling curve defines a range of actual positions of the sensed object relative to a range of changes in virtual position. The method further includes controlling display of the rendered scene according to the first scaling profile, where changes in actual movement of the sensed object generate corresponding scaled movement of the virtual position in the rendered scene.

Abstract: A system and method for controlling operation of a computer based on movements and/or position of a movable object. The system includes a sensing apparatus configured to obtain positional data based on movements of a sensed object. Engine software may process the positional data and generate control commands to produce a virtual position in an application running on the computer. A visual comparator is operatively coupled with the engine software and configured to display an actual indicator and a virtual indicator to provide a visual comparison between the virtual position and the actual position of the sensed object.
