Hilaire ported the $1 stroke/gesture recognizer to Cuis. I had
remembered the PalmOS Graffiti system of single character pen/stroke
character recognition, but $1 and Protractor recognizers did not do as
well as I would like with these gestures.
The saying goes "An Engineer is someone who can build for a dollar what
any damn fool can build for ten."
So I did a literature search and came up with a "ten cent" strategy.
It is currently untuned, with alpha quality recognition, but there is
now a Cuis-Smalltalk-UI/tools/UI-StrokeRecognizer.pck.st which I thought
I might demo.
If you want to play, just
Feature require: 'UI-StrokeRecognizer'
then use the World Menu -> New Morph.. >> StrokeInput
-> StrokeInputMorph -- shows attached gesture graphic
-> CompassTrainingMorph -- Allows one to define and register gestures
[Need "explore morph" to access].
-> EditorwithStrokeInput -- A text editor which allows stroke input
as well.
The Graffiti system was done for small screens and measured ~20% faster
than "thumb typing" on those tiny "smart"phone keyboards.
I am going on vacation soon and won't get much chance to improve
recognition before I get back, but I think this is a good example of
building a tool to be successful (the CompassTrainingMorph).
See CompassRecognizer class comments for overview/details.
I see the next First Wednesday is 2nd October, and I leave on the 3rd,
so could do this.
[Hilaire, I will need to "preflight" the Jitsi/meetup to be sure my old
computer can show the screen.]
Anyway, if everything works out and the stars align, would folks like to
see a demo on 2 October?
