Genie was a great recognition engine developed by nathanael when he was at disney. It was impressive compared with HP tablet pc software. You could steer the complete UI with it. Nathanael went to show it to Smasung research labs and HP at that time. Just before the layoff of SqueakC from HP Genie - learns in one pass a gesture no need to rehearse or you to adapt - had sophisticated settings (display size, battery consumption, speed of the stroke) - context dictionary so the same gesture could have different meaning in different contexts - has a really good documentation this are some of the class comments http://www.iam.unibe.ch/~schaerli/smalltalk/genie/genieIntroduction.htm Now Genie needed a hook in the min event pasteUp loops so we removed the patch because it was slowly the complete UI. Now that we have a cleaner event model and hook I would really love to see how we could hook Genie in Pharo. Since they is an interest for iPhone and may be new tablet. Stef
