FREE-SPACE MULTI-DIMENSIONAL ABSOLUTE POINTER USING A PROJECTION MARKER SYSTEM

摘要

Methods and apparatuses for a free-space multi-dimensional absolute pointer using a projection marker system are described herein. In one embodiment, a presentation system includes, but is not limited to, a projection- based marker apparatus to project one or more optical spots on a display surface for displaying machine generated content capable of being manipulated via a cursor of a pointing device, a handheld device to wirelessly capture the projected optical spots from the display surface, and a control unit communicatively coupled to the projection-based marker apparatus and the handheld device to determine coordinates of the cursor based on characteristics of the captured light spots. Other methods and apparatuses are also described.
