Absolute Position Encoding and Decoding Scheme

Existing pointing systems like mouse, track ball and digital tablet track the movement in x-y co-ordinates. All these systems need a PC. Absolute Pen Position Encoding and Decoding Scheme presented in this paper tracks the absolute position of a pattern printed on a paper and also records the page number. Such system is a necessity in recording voluminous data and storing them on the computer. The proposed pen position system reads the encoded pattern printed on the paper, processes it using existing image processing techniques, identifies x, y location, page number and makes it available for use in computer environment.
