Three-dimensional (3D) human-computer interaction system using computer mouse as a 3D pointing device and an operation method thereof

摘要

A three-dimensional user interface system includes at least one pointing/input device and an imaging device configured for capturing one or more image frames each providing at least two different views of a scene including the at least one pointing/input device. The imaging device is a multi-view imaging device which provides at least two different views of the scene per each of the one or more image frames captured. One or more software programs calculate from reference points in the image frames at least a spatial and a velocity parameter of the at least one pointing/input device when moved through a three-dimensional space and for rendering on a graphical user interface of a computing device a visual marker corresponding to the spatial and velocity parameters of the at least one pointing/input device in three-dimensional space. Methods for three-dimensional pointing and/or data input incorporating the described system are also provided.

1. A three-dimensional user interface system, comprising:
at least one pointing/input device including a plurality of visible indicia on a surface thereof; a multi-view imaging device configured for capturing a plurality of sequential image frames, each of the captured image frames providing at least two different views of a scene comprising the at least one pointing/input device; and at least one computer program product operable on a computing device having at least one processor, at least one memory, and at least one graphical user interface; wherein the at least one computer program product includes executable instructions for calculating from the plurality of sequential image frames at least a spatial and a velocity parameter of the at least one pointing/input device when moved through a three-dimensional space, and for rendering, on the graphical user interface, a visual marker corresponding to the spatial and velocity parameters of the at least one pointing/input device in three-dimensional space.
