CLAIMS

1. A head mounted display device for motion based view matrix tuning comprising: a display;

a processor;

a non-volatile storage device holding instructions executable by the processor to:

detect a reference location that is at least a threshold distance away from a rendering focal plane of the head mounted display device;

generate a first plurality of view matrices, each view matrix corresponding to a different inter-pupillary distance within a first range of inter-pupillary distances;

render a first plurality of holograms, each hologram rendered using a different view matrix from the first plurality of view matrices;

display the first plurality of holograms on the display at the reference location; output a first instruction to a user of the head mounted display

device to move the user' s head while viewing the first plurality of holograms and to select a hologram from among the first plurality of holograms with a most stable appearance; determine a calibrated inter-pupillary distance based on the view

matrix of the selected hologram; and

calibrate the head mounted display device based on the calibrated inter-pupillary distance.

2. The head mounted display device of claim 1, wherein the threshold distance is between 10% and 40% of a distance from the head mounted display device to the rendering focal plane.

3. The head mounted display device of claim 1, wherein the reference location is a physical marker having an identifiable characteristic known to the head mounted display device.

4. The head mounted display device of claim 1, wherein the reference location is a physical surface viewed by the head mounted display device.

5. The head mounted display device of claim 1, wherein the first plurality of holograms are static 3D images.

6. The head mounted display device of claim 1, wherein the first plurality of holograms are dynamic 3D images.

7. The head mounted display device of claim 1, wherein the non-volatile storage device holds further instructions to:

determine a second range of inter-pupillary distances based on the calibrated inter-pupillary distance;

generate a second plurality of view matrices, each view matrix corresponding to a different inter-pupillary distance within the second range of inter-pupillary distances; render a second plurality of holograms, each hologram rendered using a different view matrix from the second plurality of view matrices;

display the second plurality of holograms on the display at the

reference location;

output a second instruction to the user of the head mounted display

device to move the user' s head while viewing the second plurality of

holograms and to select a second hologram from among the second plurality of holograms with a most stable appearance; and

recalculate the calibrated inter-pupillary distance based on the view matrix of the selected second hologram.

8. The head mounted display device of claim 7, wherein the second range of inter-pupillary distances is a smaller range than the first range of inter-pupillary distances.

9. A method for motion based view matrix tuning for a head mounted display device, the method comprising:

detecting a reference location that is at least a threshold distance away from a rendering focal plane of the head mounted display device;

generating a first plurality of view matrices, each view matrix corresponding to a different inter-pupillary distance within a first range of inter-pupillary distances;

rendering a first plurality of holograms, each hologram rendered using a different view matrix from the first plurality of view matrices;

displaying the first plurality of holograms on the display at the

reference location;

outputting a first instruction to a user of the head mounted display

device to move the user' s head while viewing the first plurality of

holograms and to select a hologram from among the first plurality of

holograms with a most stable appearance;

determining a calibrated inter-pupillary distance based on the view

matrix of the selected hologram; and

calibrating the head mounted display device based on the calibrated inter-pupillary distance.

10. The method of claim 9, wherein the reference location is a physical marker having an identifiable characteristic known to the head mounted display device.

11. The method of claim 9, wherein the reference location is a physical surface viewed by the head mounted display device.

12. The method of claim 9, wherein the first plurality of holograms are static 3D images.

13. The method of claim 9, wherein the first plurality of holograms are dynamic 3D images.

14. The method of claim 9, further comprising:

determining a second range of inter-pupillary distances based on the calibrated inter-pupillary distance;

generating a second plurality of view matrices, each view matrix corresponding to a different inter-pupillary distance within the second range of inter-pupillary distances; rendering a second plurality of holograms, each hologram rendered using a different view matrix from the second plurality of view matrices;

displaying the second plurality of holograms on the display at the

reference location;

outputting a second instruction to the user of the head mounted display device to move the user's head while viewing the second plurality of holograms and to select a second hologram from among the second plurality of holograms with a most stable appearance; and

recalculating the calibrated inter-pupillary distance based on the view matrix of the selected second hologram.

15. The method of claim 14, wherein the second range of inter-pupillary distances is a smaller range than the first range of inter-pupillary distances.
