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