Claim One:
1. A viewing aid comprising: a camera; a viewing surface within a field of view of the camera, and substantially fixed relative to the camera; a memory in data communication with the camera; and a display in data communication with the memory; wherein the camera is configured to capture an initial image of viewing material on the viewing surface and to store the initial image in the memory; the viewing aid further comprising software programmed to 1) determine a first location of a tracking element within the field of view by identifying X-Y coordinates of the location based on an X-Y reference frame associated with the field of view, 2) map the location to a corresponding first mapped portion of the initial image in the memory which is less than the full initial image, 3) display on the display a first magnified image generated from the initial image stored in the memory, the first magnified image corresponding only to the first mapped portion of the initial image, 4) continuously track a motion of the tracking element to successive locations within the field of view different than the first location using the camera, 5) map the successive locations to corresponding successive mapped portions of the initial image in the memory which is less than the full initial image, and 6) display on the display successive magnified images generated from the initial image stored in the memory, the successive magnified images corresponding only to respective successive mapped portions of the initial image thereby panning the initial image to correspond to the motion of the tracking element.
