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.

Perception based predictive tracking for head mounted displays

A virtual reality (VR) console receives slow calibration data from an imaging device and fast calibration data from an inertial measurement unit on a virtual reality headset. Using a model of the VR headset, the VR console identifies model locators corresponding to locators on the VR headset and generates estimated positions for locators included in slow calibration data. The VR console adjusts calibration parameters so a relative distance between estimated positions of the locators and positions of their corresponding model locators is less than a threshold value. From the estimated positions, the VR console generates calibrated positions of a reference point on the VR headset associated with images from the slow calibration data. The VR console determines predicted positions of the reference point from the calibrated positions and adjusts calibration parameters so intermediate estimated positions of the reference point are within a threshold distance of the predicted positions.
