Abstract: A method for orienting a dual mouse optical scanner on an orthogonal grid pattern comprising the steps of (a) placing a dual mouse scanner on a grid pattern at a small angle to the vertical lines of the grid pattern and commencing motion detection with the two mice, (b) setting the coordinate position of each mouse at (0,0), (c) rotating the scanner in a predetermined manner while measuring the vertical distance on the grid pattern between the two mice for each new position of the scanner, (d) determining an average scanner position amongst all scanner positions having the same maximum vertical grid distance between the mice, and (e) establishing the coordinate position of one mouse at the average scanner position as the origin of a coordinate system in the memory of a computer in communication with the scanner and the vertical line closest to the origin and the coordinate position of the other mouse as the vertical axis of the coordinate system.

Abstract: A method for using a scanner to scan pixel data from an image on a page and map the scanned pixel data in a computer's memory is disclosed comprising the steps of (a) placing a scanner having an elongated detector array of detector elements and two optical mice located in relation to the ends of the array on a transparent grid pattern covering an image on a page to be scanned, (b) determining the orientation of the scanner with respect to the grid pattern using motion detection information provided by the two mice, (c) positioning the scanner at a starting point from which to start detecting the position of the mice and commencing scanning of the page by moving the scanner across the surface of the grid pattern, and (d) storing pixel data scanned by each detector element at a memory address of a computer in communication with the scanner which corresponds to a coordinate position on the grid pattern determined to be nearest the actual position of a particular detector element.
