Abstract

Claims (28)

1. A virtual image system, comprising:

a display subsystem configured to present a plurality of frames being presented to an end user; and

a processor configured to:

for each of at least some of the plurality of frames being presented to the end user, determine a location of appearance of a virtual object in a field of view of the end user relative to an end user frame of reference;

adjust a presentation of at least one subsequent frame based at least in part on the determined location of appearance of the virtual object in the field of view of the end users;

predict an occurrence of a head movement of the end user based at least in part on the determined location of appearance of the virtual object in the field of view of the end user;

estimate at least one value indicative of an estimated speed of the predicted head movement of the end user;

determine at least one first value that at least partially compensates for the estimated speed of the predicted head movement of the end user;

render the at least one subsequent frame based at least in part on the determined first value; and

estimate at least one change in a speed in the predicted head movement of the end user, wherein the at least one change in the speed occurs between a start of the predicted head movement and an end of the predicted head movement, and wherein estimating the at least one value indicative of the estimated speed of the predicted head movement includes estimating the at least one value indicative of the estimated speed that at least partially accommodates for the at least one estimated change in the speed in the predicted head movement of the end user.

2. The system of claim 1 , wherein the virtual object is newly introduced in the field of view of the end user temporally relative to previous frames presented to the end user.

3. The system of claim 2 , wherein the newly introduced virtual object is determined to likely attract an attention of the end user.

4. The system of claim 1 wherein the virtual object is in a new position in the frame relative to a position in at least one previous frame.

5. The system of claim 1 , wherein the processor is further configured to select the virtual object based on input indicative of an attention of the end user to the virtual object.

6. The system of claim 5 wherein the input indicative of the attention of the end user to the virtual object is based at least in part on an appearance of the virtual object in a new position as presented to the end user relative to a position of the virtual object as previously presented to the end user.

7. The system of claim 5 wherein the input indicative of the attention of the end user to the virtual object is based at least in part on how quickly a position of the virtual object as presented to the end user changes relative to the position of the virtual object as previously presented to the end user.

8. The system of claim 1 wherein the virtual object is in a new position as presented to the end user relative to a previous position of the virtual object as previously presented to the end user.

9. The system of claim 1 wherein the processor is further configured to adjust the presentation of the at least one subsequent frame by presenting the at least one subsequent frame with a center of the at least one subsequent frame shifted toward, but not centered on, the determined location of appearance of the virtual object in the field of view of the end user.

10. The system of claim 1 , wherein the processor is further configured to adjust the presentation of the at least one subsequent frame by presenting the at least one subsequent frame with a center of the at least one subsequent frame shifted to the determined location of appearance of the virtual object in the field of view of the end user.

11. The system of claim 1 wherein the processor is further configured to estimate at least one change in the speed in the predicted head movement of the end user by estimating the at least one change between a first defined time after the start of the predicted head movement and a second defined time before the end of the predicted head movement.

12. The system of claim 1 , the processor is further configured to:

estimate at least one value indicative of an estimated acceleration of the predicted head movement of the end user;

determine at least one second value that at least partially compensates for the estimated acceleration of the predicted head movement of the end user; and

render the at least one subsequent frame based at least in part on the determined second value.

13. The system of claim 1 , the processor is further configured to further comprising:

receive information indicative of an identity of the end user; and

retrieve at least one user specific historical attribute for the end user based on the received information indicative of the identity of the end user, wherein the user specific historical attribute is indicative of at least one of a previous head movement speed for the end user, a previous head movement acceleration for the end user, and a previous eye movement to head movement relationship for the end user.

14. The system of claim 1 wherein the virtual object is at least one of a virtual text object, a virtual numeric object, a virtual alphanumeric object, a virtual tag object, a virtual field object, a virtual chart object, a virtual map object, a virtual instrumentation object or a virtual visual representation of a physical object.
