Private and Public refers to a characteristic of who can view rules (and therefore certain xR experiences) and which objects upon which rules may or may not be applied. Making an xR experience private means that such rules or xR experience can restricted to a specified or known user (or defined subset of users) meeting a certain criteria. Making an xR experience public means the experience is made available to all users or a specified type of group of users based on predefined properties.
Proximity refers to the distance between objects, actors, xR experiences, and rendering devices based on varying locations and time. Proximity may be specific to rendering device and rendering device capability. For example, rendering device may need to calculate and format proximity differently based on car heads up display on windshield, wearable glasses, retinal display or phone. Proximity may apply to and be determined differently for visual distance, sound distance and smell distance. For example, a sound coming from a certain direction or angle may be made to behave more realistically by having it sound like it is getting closer or farther away as a consumer moves their current position or head relative to the virtual sound source.
A Real World Data Representation Service (RWDRS) refers to systems and/or services that store image, video, point matrices, polygon meshes, voxels (light field information), depth maps or other recognition information that can be used to identify an object and its location and facilitate seamlessly mapping of an xR experience to objects and/or locations.
A Rendering Device refers to a phone, glasses, head-up display (HUD) or other device (e.g., used by a consumer to render and consume an xR experience vis one or more of sight, sound, touch, smell or taste.
