Abstract

An augmented reality display system comprises a passable world model data comprises a set of map points corresponding to one or more objects of the real world. The augmented reality system also comprises a processor to communicate with one or more individual augmented reality display systems to pass a portion of the passable world model data to the one or more individual augmented reality display systems, wherein the piece of the passable world model data is passed based at least in part on respective locations corresponding to the one or more individual augmented reality display systems.

Claims

1. A method for displaying augmented reality, comprising:

displaying a virtual object to a user of an augmented reality display system;

associating a navigation object to the virtual object, wherein a navigation object is configured to be responsive to one or more predetermined conditions; and

modifying at least one parameter of the virtual object in response to the one or more predetermined conditions.

2. The method of claim 1, further comprising maintaining a collection of navigation objects, wherein a plurality of navigation objects of the collection of navigation objects are associated with the virtual object.

3. The method of claim 1, wherein the one or more predetermined conditions comprises a presence of a structure.

4. The method of claim 1, wherein the one or more predetermined conditions comprises a detection of a light source or a source of light.

5. The method of claim 1, wherein the one or more predetermined conditions comprises a detection of a sound or a source of sound.

6. The method of claim 1, wherein the one or more predetermined conditions comprises a source of food or water.
