Abstract
In one embodiment, a method of rendering images includes providing eyewear having at least one lens capable of mutual occlusion for optical see-through HMD applications. A display module routes image from an ambient real world environment first through a spatial light modulator so that selective portions of the real world scene can be pixel-wise occluded. The resultant modulated image is then combined with another computer generated virtual image and then routed to the viewer. In another embodiment an electrically actuated switchable occlusion mechanism is provided within the display module that allows the ability to provide the occlusion capability only when needed.
