A METHOD AND APPARATUS FOR HANDWRITING CAPTURE, STORAGE, AND IND EXING

摘要

A handwriting capture and storage device (HCSD) comprises a digitizer (170) for generating X, Y coordinates corresponding to movement of a pen on a digitizer surface. A micro-controller (121) stores the X, Y coordinate data in a compressed format in a randomly accessible permanent storage (123). The X, Y coordinate data is provided later to a digital processing system for further processing to perform functions such as character recognition. An HCSD need not perform character recognition function, the device can be implemented to consume minimal power and space. The present invention further provides a flexible indexing scheme which enables a user to organize information written as multiple pages. The indexing scheme allows data to be added into pre-existing pages without having to copy the whole page to a new place in the non-volatile memory.
