Abstract
In an exemplary display system adapted to display an image to an observer using a display where at least one of the display and observer is subjected to physical vibration referred to as jitter, accelerometers are mounted to elements subject to jitter and associated with the observer. A processing system uses acceleration measurements from the accelerometers to calculate an x-axis and y-axis jitter correction factors based on a comparison of the acceleration measurements, and generates a video output in which the visual information is displaced along the x-axis and y-axis based on the x-axis and y-axis jitter correction factors so that an image corresponding to the video output shown on the display appears to the observer as not having jitter.
