I am not aware of any such at effort at the W3C (although the InidieUI might be doing some work that is loosely related <http://www.w3.org/WAI/IndieUI/>). Gestures were discussed when the Web Events WG (Touch Event API) was chartered and they were explicitly *not* included in scope because of IP/patent concerns <http://www.w3.org/2010/webevents/charter/Overview.html>. > The only related documents I could find are [0] from 2009 and a > proprietary Microsoft implementation [1]. > > In case there is none Iıd like to start one. Perhaps starting a Community Group would be a good way to get started. (If you decide to go that route and need a supporter, please let me know. I don't know if I would actually formally join such a CG but I do support having a Public conversation about this topic.) > Currently I am writing (yet another) JS library [2] to support some > gestures like tap, dbltap, hold, pinch, flick, swipe. > Other libraries like Hammer [3] canıt handle multiple pointers > simultaneously or lack of accuracy when detecting gesture [4] (e.g. Hold > is not aborted on move). > > Imho a specification should cover a Gesture interfaces and its properties > + constraints like the maximum movement (in inch) for a pointer to be > recognised as a tap or the ³hold" time.

I Cc'ed the Touch Events CG and Pointer Events WG lists since some of those people might be interested. -AB > Regards, > Damien > > > [0] http://lists.w3.org/Archives/Public/www-dom/2009AprJun/0134.html > [1] http://msdn.microsoft.com/en-us/library/ie/dn433243%28v=vs.85%29.aspx > [2] https://github.com/PolyTouch/PolyTouch.js > [3] http://eightmedia.github.io/hammer.js/ > [4] https://github.com/Polymer/PointerGestures/ > [5] > http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2010-February/279622.ht > ml > > > >
