摘要
Methods and systems for surface-free pointing and/or command input include a computing device operably linked to an imaging device. The imaging device can be any suitable video recording device including a conventional webcam. At least one pointing/input device is provided including first and second sets of visible point light sources, wherein the first and second sets emit differently colored light. The imaging device captures one or more sequential image frames each including a view of a scene including the first and second sets of visible point light sources. One or more software programs calculate a position and/or a motion and/or an orientation of the pointing/input device in the captured image frames by identifying colored areas corresponding to the first set of aligned visible point light sources. Certain activation patterns of individual point light sources are mapped to particular pointing and/or input commands.
