Graffiti (PalmOS)
Graffiti is the handwriting
recognition software used in PDAs
based on the Palm
OS. Graffiti also runs on the Pocket
PC, where it's called "Block Recognizer".
The software is based primarily on upper-case characters that
can be drawn blindly with a stylus on a touch-sensitive panel.
Since the user typically cannot see the character as it is being
drawn, complexities have been removed from four of the most
difficult letters. 'A', 'F', 'K' and 'T' all are drawn without
any need to match up a cross-stroke.
The Graffiti system has been the subject to a patent issue from Xerox,
with its Unistrokes technology. Because of this, Palm
has discontinued the use of the Graffiti system as it stood in
further versions of its Palm OS software and instead licensed a
variant of the Jot system from CIC,
however the two systems are not identical.
