Abstract
A display system comprises a projector combined with a retro reflective screen and a viewer distance from the projector such that the observation angle is less than approximately 2-3 degrees. The brightness of the image on the screen for the proposed display system is increased by a factor of ˜100-500× as compared to traditional display systems with for an equivalent power/intensity light source.
Claims20
A display system providing an augmented reality experience, comprising:
- a retroreflective screen configured to reflect incident light to a viewer that is at an observation angle less than about 3° at a distance of at least about 2 feet from said retroreflective screen;
- a projector for projecting light characterizing an image or video associated with at least one virtual object directly onto said retroreflective screen, which at least one virtual object is associated with a tangible physical object in optical communication with said viewer;
- and
- a computer processor in communication with said projector, wherein said computer processor is programmed to direct said projector to project said light characterizing said image or video associated with said at least one virtual object directly onto said retroreflective screen, which at least one virtual object is associated with said tangible physical object in optical communication with said viewer, such that said viewer is provided with said augmented reality experience.

A method for providing an augmented reality experience, comprising:
- a. directing light characterizing an image or video associated with at least one virtual object from a projector directly onto a retroreflective screen in optical communication with said projector, which at least one virtual object is associated with a tangible physical object in optical communication with a viewer;
- and
- b. presenting light reflected from said retroreflective screen to said viewer that is at an observation angle less than about 3° at a distance of at least about 2 feet from said retroreflective screen, which at least one virtual object is associated with said tangible physical object in optical communication with said viewer, such that said viewer is provided with said augmented reality experience.
