DIRECT THREE-DIMENSIONAL POINTING USING LIGHT TRACKING AND RELATIVE POSITION DETECTION

摘要

A computing system for direct three-dimensional pointing includes at least one computing device, and a pointing/input device including at least one light source and a motion sensor module for determining absolute and relative displacement of the pointing/input device. At least one imaging device is configured for capturing a plurality of image frames each including a view of the light source as the pointing/input device is held and/or moved in a three-dimensional space. Two or more imaging devices may be provided. A computer program product calculates at least a position and/or a motion of the light source in three-dimensional space from the plurality of sequential image frames and from the pointing/input device absolute and relative displacement information, and renders on the graphical user interface a visual indicator corresponding to the calculated position and/or the motion of the light source. Methods for direct three-dimensional pointing and command input are described also.

1. A computing system for direct three-dimensional pointing and command input, comprising:
at least one computing device having at least one processor, at least one memory, and at least one graphical user interface; a pointing/input device including at least one light source and a motion sensor module providing information regarding an absolute and a relative displacement of the pointing/input device to the at least one computing device; at least one imaging device operably linked to the computing device processor and configured for capturing a plurality of image frames each including a view of the at least one light source as the pointing/input device is held and/or moved in a three-dimensional space and within a field of view of the at least one imaging device; and at least one non-transitory computer program product operable on the computing device processor; wherein the at least one computer program product includes executable instructions for calculating at least a position and/or a motion of the at least one light source in three-dimensional space from the plurality of sequential image frames and from the pointing/input device absolute and relative displacement information, and for rendering on the graphical user interface a visual indicator corresponding to the calculated position and/or the motion of the at least one light source.
