Universal computing device

Abstract

The universal input device provides a common user interface for a variety of different computing platforms including printed documents. Using the present system, one may use the universal input device to control various computing devices as well as capture handwritten electronic ink and have the electronic ink be associated with new or stored documents. The universal input device can be identified by a specific identification in order to allow for multiple users to operate on a document and / or within an application program simultaneously or not. An off-set optical system with infrared illumination handles perspective and helps detect positional encoding which can be covered by existing ink under common visible light illumination.

Description

[0001] This application is a continuation-in-part of US Patent Application Serial No. 10 / 284,417, filed October 31, 2002, and entitled "General Computing Device," which is hereby incorporated by reference. technical field [0002] Features of the present invention are generally directed to computer input devices for generating smooth electronic ink. More specifically, features of the invention are directed to input devices that can be used on divergent platforms while providing a common user interface. Background technique [0003] Computing systems have dramatically changed the way we live. The first wave of computers were prohibitively expensive and cost-effective to use only in commercial settings. As computers have become more readily available, the use of personal computers at work and at home has become so widespread that computers have become as common as desks in offices and dining tables at home. Microprocessors are already incorporated into every aspect of our da...
