1. A computing system for tracking a motion and/or an orientation of a pointing/input device, comprising:

  • a computing device having at least one processor, at least one memory, and at least one graphical user interface;

    at least one pointing/input device including a first set of aligned visible point light sources emitting light of a wavelength defining a first predetermined color and a second set of visible point light sources emitting light of a wavelength that defines a second predetermined color that is different from the first predetermined color;

    an imaging device operably linked to the computing device and configured for capturing a plurality of sequential image frames; and

    at least one computer program product operable on the computing device processor, the at least one computer program product including executable instructions for determining at least a position and/or a motion and/or an orientation of the at least one pointing/input device from digital data of the plurality of sequential image frames providing views of the first and second sets of visible point light sources held and/or moved in a three-dimensional space within a field of view of the imaging device, and for rendering on the graphical user interface a visual marker corresponding to the determined position and/or the motion and/or the orientation of the at least one pointing/input device.
