Abstract:
1. A method of predictive tracking for a head mounted display comprising: obtaining one or more three-dimensional angular velocity measurements from a sensor monitoring a head mounted display; 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 one or more angular velocity measurements indicate that the head mounted display is substantially stationary and the prediction interval increases up to a predetermined latency interval when the one or more angular velocity measurements indicate that the head mounted display is moving at an angular velocity at or above a predetermined threshold, the prediction interval being equal to or less than the predetermined latency interval; predicting a three-dimensional orientation for the head mounted display using the one or more three-dimensional angular velocity measurements extrapolated over the prediction interval 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.
