Here are some pointers to our recent papers generally relevant to optical character recognition, but more specifically aimed at reading mathematical expressions from typeset documents. We have not worked on handwritten documents or real-time handwriting recognition. I've been thinking about how to represent scientific documents for use on the world-wide web. So have a number of other people.
Comments are more than welcome.
If you have only a slow connection to the network, you might consider deferring the downloading of the figures in this next paper. It is an html description of current work here in interactive zoning and OCR processing. Optical Character Recognition and Parsing of Typeset Mathematics. They re-typeset it by hand. Progress in recognizing typeset mathematics.
