MOTOROLA'S LEXICUS CLAIMS HANDWRITING BREAKTHROUGH

December 2, 1994 -- Lexicus Corp, the Palo Alto handwriting recognition
software developer acquired by Motorola Inc last year, is set to go with
its flagship Lexicus Longhand Handwriting Recognition Software for
Developers. Claimed to be the first cursive handwriting recognition
software designed for the Windows for Pen operating system, the software
applies neural network technology to recognise and correct natural
handwriting - cursive, print or a mixture of the two - and is claimed to
provide faster and more accurate recognition than previously available.
The neural network technology is used to train the Lexicus Longhand system
to recognise natural handwriting. Lexicus sees Longhand being used in
medical applications such as prescription writing, psychiatric notes and
clinical drug trials, and sales force automation, market surveys and
police incident reports.

It is claimed to be able to correct spelling errors and accommodate
difficult-to-recognise cursive handwriting. Accuracy is derived from a
25,000 word built-in dictionary with a customisable user dictionary to
correct errors on the fly, anticipate common user words, and recognise
proper nouns. It is claimed to do its thing at 12 characters per second,
making handwritten text more legible, readable and more efficiently
stored. Lexicus Longhand is user-installable without additional hardware
or software beyond the Windows for Pen requirements, the company says, and
is writer-independent, easily learned and does not require training.
Lexicus Longhand learns each user's vocabulary and adapts to the user's
subject matter, but it can also accommodate multiple users in a shared
environment.

It converts cursive handwriting to ASCII, saving space and enabling users
to save text on notebooks and input text to client-server and
enterprise-wide computer systems. Saved text can then be searched for key
words at a later date - all of which explains why Motorola thought that a
company working in such a currently unfashionable and unfancied niche was
worth buying. The developer version of Lexicus Longhand will be shipping
next month and will sell for $150.
