Edgewrite looks like the same kind of thing the old Palm Pilots used.

Graffiti, yes. Edgewrite should perhaps be called "Cornerwrite;" in its optimized alphabet, the every stroke begins and ends in a corner and every change in direction is at a corner. https://en.wikipedia.org/wiki/Graffiti_(Palm_OS) https://en.wikipedia.org/wiki/Graffiti_(Palm_OS)

  Yes that would indeed by an accurate description!

Yes the author of edgewrite talks extensivly about grafiti but claims some advantages over that system. I'd like to do a web demoable implementation of edgewrite but it's kind of hard for me to get a hand on a Palm Pilot. Have you used that system?

I saw a guest lecture last semester from Rob Haitani, the UI designer on the original Palm Pilot [1]. He talks about their Graffiti text entry from about 00:07:00 to 00:12:00: One thing we learned from our testing was, the absolute speed and accuracy weren’t actually the critical point. It was really the overall experience... So with the [Apple] Newton [handwriting recognition] and other technologies, you would write something, and you would go one Mississippi two Mississippi, and boom it would show up. And if it’s wrong, oh crap. You erase it, and then you try again like one Mississippi two Mississippi. But with Graffiti you’re just going a-b-c-d-e, and if you make a mistake, like your keyboard on your computer, you just have this backspace stroke, and so it’s very fast to recover from errors, so you just keep going. I think there's a parallel here with swiping gestures for words on smartphone keyboards, where I find that when the gesture is misinterpreted, it's frustrating because I'll have to delete the entire word and redraw it, or tap out individual letters. Which just feels bad. As a side note related to that, in the same class there was also a guest lecture from Shumin Zhai, who worked on SHARK and subsequent systems which would eventually become ShapeWriter/Swype [2]. Very cool overview to how the system works conceptually.

  Thank you so much for your comment and the links. Looks like a lot of tasty material for me to put my teeth in. Yes it seems that swype's spiritual ancestor somehow is edgewrite / graffiti text entry systems. please check out my rss http://tbf-rnd.life/feed http://tbf-rnd.life/feed if you want to get more info. I have a long backlog and I hope some interesting views as well. Also there'll be code!
