PERCEPTION BASED PREDICTIVE TRACKING FOR HEAD MOUNTED DISPLAYS |
摘要 |
There is disclosed a method of and apparatus for predictive tracking for a head mounted display. The method comprises obtaining one or more three-dimensional angular velocity measurements from a sensor monitoring the head mounted display and setting a prediction interval based upon the one or more three-dimensional angular velocity measurements such that the prediction interval is substantially zero when the head mounted display is substantially stationary and the prediction interval increases up to a predetermined latency interval when the head mounted display is moving at an angular velocity of or above a predetermined threshold. The method further includes predicting a three-dimensional orientation for the head mounted display to create a predicted orientation at a time corresponding to the prediction interval, and generating a rendered image corresponding to the predicted orientation for presentation on the head mounted display. |
