The study of Web-Based online mathematical expression recognizing technologies

As to recognizing mathematical expressions, we have designed online handwriting recognizing systems of mathematical expressions, MatheWriter and Embedded-MatheWriter, which have succeeded to be embedded in Office (like Word) and mobile equipments (like PDA). The paper expounds the system structure and basic functions of recognition system. On the basis of these studies, it also expounds the recognizing technology of mathematical expressions based on the Net and Internet Explorer, and from the perspective of Web´s characteristics, the Web-based MatheWriter is developed to help the mathematical workers find a more convenient and free model to solve difficult problems of expression input. Furthermore, it sets up a platform for inquiring into how to build a more natural and harmonious human-computer environment under the environment of ubiquitous computing through the design and realization of expression editor of this non-keyboard input.
