Abstract

Various technologies pertaining to shared spatial augmented reality (SSAR) are described. Sensor units in a room output sensor signals that are indicative of positions of two or more users in the room and gaze directions of the two or more users. Views of at least one virtual object are computed separately for each of the two or more users, and projectors project such views in the room. The projected views cause the two or more users to simultaneously perceive the virtual object in space.

Description

Background technique [0001] Spatial Augmented Reality (SAR) technology creates an augmented reality experience by using projected light to change the appearance of a physical environment. Whereas many augmented reality methods involve drawing graphics on top of live video fed from a handheld device or a headset, SAR places graphics directly on physical objects so it doesn't distract the user from the real world. A "see-through" head-mounted display can achieve a similar effect; however, conventional head-mounted displays support a limited field of view and are somewhat bulky, thereby potentially preventing face-to-face interaction between users. [0002] Under the right circumstances, a SAR system can change the appearance of a surface of an object so that it appears that such a surface is made of a particular material. For example, a SAR system can make a carpeted floor look like a mossy swamp to the user. To achieve this effect, an accurate geometric model of the physical ...
