Introduction
The ease of use provided by the classic pen and paper “interface” is unsurpassed.
However,pen and paper are hardly supported by current information technology.
The integration of paper based devices and modern computers has been hampered by two problems.
Pen And Paper
Paper has a high resolution and is thus pleasant to read.
Paper can be easily folded and crushed.
Paper supports fast input of both textual as well as graphical data.
Recording Handwriting
It has been possible to capture handwriting on paper by utilizing a standard digitizer lying beneath the paper.
The ideal device would be a pen capable of capturing handwriting,and sending recognition results to the proper destination via a wireless internet connection.
Patterned Paper
This approach is based on a barely perceptible pattern printed on all documents allowing handwritten input.
The pattern is a composition of combinatorial combinations of standard sub-patterns .
