Viewing material is placed on the viewing surface. The camera, viewing surface, and material all remain substantially stationary. The camera captures and stores an initial image of the material in the memory. The software then tracks the location of a tracking element within the field of view then maps the location to a portion of the initial image in memory using an X-Y coordinate system, and/or identifies character elements of the material adjacent the tracking element then maps the character elements to corresponding character elements of the initial image in memory. An enhanced image is then displayed on the display corresponding to the mapped portion of the initial image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Viewing aid with tracking system, and method of use","description":"A viewing aid includes a camera, a viewing surface within a field of view of the camera, a memory, a display, and software programmed to track a tracking element within the field of view.
