US Patent 10338677 Adjusting image frames based on tracking motion of eyes

In some examples, techniques and architectures for operating a device that may be wearable, such as a head-mounted device, may be used for virtual reality applications. A processor of the device may operate by dynamically tracking the cornea, and thus the gaze direction, of a user's eyes. By tracking the gaze direction, retinal velocity of a display image projected onto the retina, measured in the retina coordinate frame may be computed. Display times of image frames viewable by the user may be modified based on the retinal velocity.
