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 of displaying augmented reality, comprising:

identifying an object as a totem;

determining at least one characteristic pertaining to an interaction of a user of an augmented reality display system with the totem; and

determining a user input based at least in part on the at least one characteristic pertaining to the interaction of the user with the totem.

2. The method of claim 1, further comprising storing a correlation map, wherein the correlation map comprises a set of predetermined characteristics of the interaction with the totem and a corresponding set of user input commands, wherein the user input is determined based at least in part on the stored correlation map.

3. The method of claim 1, wherein the at least one characteristic pertains to a movement of the totem.

4. The method of claim 1, wherein the at least one characteristic pertains to a direction of movement of the totem.

5. The method of claim 1, wherein the at least one characteristic pertains to a placement of the totem relative to the world.

6. The method of claim 5, wherein a predetermined reference frame is consulted to determine the interaction of the user with the totem.

7. The method of claim 5, wherein the predetermined reference frame comprises a head-centric reference frame.

8. The method of claim 5, wherein the predetermined reference frame comprises a hand-centric reference frame.

9. The method of claim 5, wherein the predetermined reference frame is a body-centric-reference frame.

10. The method of claim 1, wherein the at least one characteristic pertains to a movement of the user relative to the totem.

11. The method of claim 1, further comprising designating the real object as the totem.

12. The method of claim 1, further comprising selecting a known pattern of interaction with the totem;

and mapping the selected known pattern of interaction to a user input command.

13. The method of claim 12, wherein the mapping is based at least in part on user input.

14. The method of claim 1, further comprising rendering a virtual user interface in relation to the identified totem.

15. The method of claim 1, wherein the predetermined reference frame comprises a world-centric reference frame.
