Abstract: A system includes a head mounted display (HMD) device comprising at least one display and at least one sensor to provide pose information for the HMD device. The system further includes a sensor integrator module coupled to the at least one sensor, the sensor integrator module to determine a motion vector for the HMD device based on the pose information, and an application processor to render a first texture based on pose of the HMD device determined from the pose information. The system further includes a motion analysis module to determine a first velocity field having a pixel velocity for at least a subset of pixels of the first texture, and a compositor to render a second texture based on the first texture, the first velocity field and the motion vector for the HMD, and to provide the second texture to the display of the HMD device.
