StrokeIt
Back-and-forth gesturesPosted by Elmo
<HTML>Is it a side effect of your gesture recognition system that Strokeit can't recognize inline left-right or up-down gestures? I guess if it's based on a bitmap analysis that sort of thing might confuse it.
If there's a way you could add support for them, I think it would be worth the effort. Those gestures are the next simplest after straight lines, and are a lot easier to execute than curves or zigzags.</HTML>
<HTML>I'll second that!
Still not 100% sure what order to do things in. Do I draw a gesture, click learn, then add new gesture? Or do I add new gesture, draw it and then click learn? Or is it learn, draw, new? Nothing wrong with the way you have decided to do things, just that there is a lack of visual feedback to let you know if you have done things the right way or wrong way round... Also too easy to overwrite existing gestures with your own wonky ones...</HTML>
<HTML>To define a new symbol:
1) Go into learning mode. While in learning mode, StrokeIt will not exectute any commands, it will simply show you what, if anything, the symbols you draw are recognized as. 2) Draw a symbol. If strokeit recognizes the symbol, it will be be shown in the "recognized as" spot. If it's not, it will be listed as <Unrecognized Gesture> 3) You can tell strokeit what that symbol should be by selecting it from the "save as" list. If you don't want to modify the symbol, simply draw another one. StrokeIt will only learn the new symbol if you click "Learn". You can't overwrite gestures, you can only add to them. And adding a symbol to an existing gesture involves drawing an unrecognized gesture, *selecting the existing gesture from the list*, and clicking "save as".</HTML>
<HTML>First, It's not clear that just opening the Learning dialog box changes the behavior of Strokeit. Maybe just saying "Strokeit is now in Learning Mode", or having an activate/deactivate toggle would help.
>And adding a symbol to an existing gesture involves drawing an unrecognized gesture, >*selecting the existing gesture from the list*, and clicking "save as". That part is especially unclear. There's no visual indication of the "state" of the program that they're saving. I think I'd lose the review button, and instead always leave the just-drawn gesture on the screen. It would help people understand what exactly they're "saving" when they press the button. I'm not sure about how to make the actual symbol->gesture association more clear. I think the "ultimate" interface would let you actually see all the symbols that are associated with a given gesture, and let you selectively add and remove them. This would also help learning the builtin gestures, as currently you have to go to the web site and browse the predefined profiles to learn how to draw them.</HTML>
<HTML>Sometimes you need to "learn" already known gestures. I was having a hard time getting strokeit to recognize my M's, so adding a few learning things helped a lot. I also suppose some people would rather draw some things differently than as it was built in (especially as there's no list that says what each one looks like).
Like for my P's, I find it more intuitive to go down/up/draw the loop than starting from the bottom.</HTML>

Tetrad I had the same thought, so I created <a href="http://www.suicidalweasel.com/~ben/strokeit/">http://www.suicidalweasel.com/~ben/strokeit/</a> listing each shape. Then Jeff told me about <a href="http://tcbmi.com/strokeit/actions.shtml?app=files/All%20Symbols.cfg">actions Symbols</a> that are hidden on this website.</HTML> |
