Abstract
A single camera detects user interactions with separate infrared light sources, such as structured light for three dimensional detection and an infrared curtain surface touch interactions. A touch input module monitors user interactions with a desktop surface, such as at a projected or display mat user interface presentation, and selectively illuminates the separate infrared light sources to support camera detection based upon the user interactions. For example, separate infrared light sources illumination in an interleaved manned at variable rates based upon analysis of visible light or structured light images captured by the camera.
