Handwriting recognition is essential to some people's vision of future computing. It sure is to mine. This short article at The Inquirer will tell you about one such technology. The company, Epos, does not build anything, instead seeking to license the technology to others. I think they have a winner, here, and would love to have a sample.
There are others. I have a friend who programs for Electronic Arts, the game maker, here in the Dallas/Fort Worth, TX area. He tells me that within EA exists a very good pen recognition program that could be developed into a winning product, though he says the company probably won't do that. This is simply an offshoot of what they do for a living and is not seen as a product.
Further; rumor has it that Wacom, the tablet input people, will soon have a new tablet that has enough memory to be used without a PC for dozens of pages of dense text, then uploaded to the computer via encrypted BlueTooth or unencrypted USB/Firewire, depending on your preference. Combined with good handwriting recognition, this could be a killer app for a lot of people, myself included.
Interesting times, eh?
