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?
