I'm working on it.... whether I'll ever finish is uncertain though :-)
What I currently have is a little "scribble pad" application with
handwriting recognition built in, so if you tap somewhere you can
start drawing letters and digits and they are added to the scribble
pad page as text.
This is largely just to test and experiment with handwriting
I'm in the process of re-writing the recognition code so that it
(hopefully) makes fewer mistakes. It currently gets confused between
l (drawn like L) and e, has trouble recognising 8 and v, and various
other little issues. But I find it usable.
Then I'll put the recogniser into a program that grabs all touchscreen
events and feeds them back as either key strokes or stylus events.
My initial plan is that:
- a tap goes straight through as a mouse click
- a stroke is interpreted as a written symbol
- a tap-and-drag (like you can do in a notebook's touchpad) becomes
- a vertical stroke in the right 1/3 of the screen becomes a
I don't know how the tap-and-drag will feel - it might be too
Eventually (if I get that far) I'd like to have a little widget in the
illume status bar to allow selection of abc/123/stroke. But that will
be much later.
