Subject: Unistrokes for the Zoomer?
Status: RO


I have had my zoomer for a couple of months now, and I am very pleased
with the hardware, but the user interface needs a little work.
I want to be able to take notes on it and use it as digital paper when I
brainstorm, but the character recognition routine is too slow for the 
scaled down CPU, and the slow CPU is necessary for long battery life.

Personally, I doubt that fast full-character recognition is possible with a 
7.5 Mhz CPU, but I am also certain that something like Unistrokes can 
be recognized in real time.  I have no problems with learning a new way 
to write.  So, has anyone implemented on such a system?  If not, what software 
would I need to implement one myself?  How well does the Geos SDK document 
how digital ink is implemented on the ZPDA?  I essentially want
an extra keyboard option.  Can one be added?

Thanks!

PS.  For those who have not heard of unistrokes, It is a way to represent 
     characters with single strokes of a pen.  The strokes do not look like
     English letters, but with real-time character recognition, such
     similarities are not necessary.
