Abstract

In one example, a head mounted display system includes detecting a position of a head of a user of the head mounted display, predicting a position of the head of the user of the head mounted display at a time after a time that the position of the head of the user was detected, and rendering image data based on the predicted head position.

First claim

What is claimed is:

1 . A head mounted display system comprising:
one or more processor to:
detect a position of a head of a user of the head mounted display;
predict a position of the head of the user of the head mounted display at a time after a time that the position of the head of the user was detected; and
render image data based on the predicted head position.

2 . The head mounted display system of claim 1 , comprising a transmitter to transmit the rendered image data to the head mounted display.

3 . The head mounted display system of claim 1 , the one or more processor to create an image to be displayed on the head mounted display based on the predicted position and based on the rendered image data.

4 . The head mounted display system of claim 1 , the one or more processor to display an image on the head mounted display based on the rendered image data.

5 . The head mounted display system of claim 1 , the one or more processor to estimate an expected field of view of the user at a time of display, and to render the image data based on the predicted head position and based on the expected field of view.

6 . The head mounted display system of claim 1 , the one or more processor to perform a two dimensional transform on the rendered image data.

7 . The head mounted display system of claim 1 , the one or more processor to maintain a weighted average of past head position vectors, and to predict the position of the head based on the weighted average.

8 . The head mounted display system of claim 1 , the one or more processor to predict the position of the head based on a filtering method.

9 . The head mounted display system of claim 1 , the one or more processor to predict the position of the head based on dead reckoning.

10 . The head mounted display system of claim 1 , the one or more processor to render the image data based on a predicted amount of motion and latency.

11 . The head mounted display system of claim 1 , the one or more processor to determine a latency to display the rendered image data, and to predict the position of the head of the user based on the detected position and based on the determined latency.

12 . A method comprising:
detecting a position of a head of a user of a head mounted display; predicting a position of the head of the user of the head mounted display at a time after a time that the position of the head of the user was detected; and rendering image data based on the predicted head position.

13 . The method of claim 12 , comprising transmitting the rendered image data to the head mounted display.

14 . The method of claim 12 , comprising creating an image to be displayed on the head mounted display based on the predicted position and based on the rendered image data.

15 . The method of claim 12 , comprising displaying an image on the head mounted display based on the rendered image data.

16 . The method of claim 12 , comprising estimating an expected field of view of the user at a time of display, and rendering the image data based on the predicted head position and based on the expected field of view.

17 . The method of claim 12 , comprising rendering the image data based on a predicted amount of motion and latency.

18 . The method of claim 12 , comprising determining a latency to display the rendered image data, and predicting the position of the head of the user based on the detected position and based on the determined latency.

19 . One or more tangible, non-transitory machine readable media comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to:
detect a position of a head of a user of a head mounted display; predict a position of the head of the user of the head mounted display at a time after a time that the position of the head of the user was detected; and render image data based on the predicted head position.

20 . The one or more tangible, non-transitory machine readable media of claim 19 , comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to transmit the rendered image data to the head mounted display.

21 . The one or more tangible, non-transitory machine readable media of claim 19 , comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to create an image to be displayed on the head mounted display based on the predicted position and based on the rendered image data.

22 . The one or more tangible, non-transitory machine readable media of claim 19 , comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to display an image on the head mounted display based on the rendered image data.

23 . The one or more tangible, non-transitory machine readable media of claim 19 , comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to:
estimate an expected field of view of the user at a time of display; and render the image data based on the predicted head position and based on the expected field of view.

24 . The one or more tangible, non-transitory machine readable media of claim 19 , comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to render the image data based on a predicted amount of motion and latency.

25 . The one or more tangible, non-transitory machine readable media of claim 19 , comprising a plurality of instructions that, in response to being executed on at least one processor, cause the at least one processor to:
determine a latency to display the rendered image data; and predict the position of the head of the user based on the detected position and based on the determined latency.
