Abstract
A system and method are described for selecting and identifying a unique object or feature in the system user's three-dimensional (“3-D”) environment in a two-dimensional (“2-D”) virtual representation of the same object or feature in a virtual environment. The system and method may be incorporated in a mobile device that includes position and orientation sensors to determine the pointing device's position and pointing direction. The mobile device incorporating the present invention may be adapted for wireless communication with a computer-based system that represents static and dynamic objects and features that exist or are present in the system user's 3-D environment. The mobile device incorporating the present invention will also have the capability to process information regarding a system user's environment and calculating specific measures for pointing accuracy and reliability.
