Abstract
Embodiments of the invention provide apparatuses, methods, and systems for projecting images into a projection zone, while having the capability to detect the presence and movement of objects in the projection zone and to interact with those objects, according to programmed interactions. One of the programmed interactions may be to detect objects in the projection zone and avoid projecting light onto them. The capability to detect and avoid objects in the projection zone may allow for the use of high intensity light images including laser light images around people and animals without the risk of eye injury. Another programmed interaction may be to project an illuminated image around people and objects in the projection zone to emphasize their presence and movement.
