Hi, The W3C pointer events working group [1] has put out their first editors draft of the Pointer Events specification [2]. Pointer events offer a number of advantages over the current mouse event + touch event model in WebKit. In particular, having apps state clearly and declaratively [3] whether a touch that starts on an element should result in browser behavior like scrolling or events which can be handled from JavaScript is potentially a big win for touch scrolling performance (something we struggle with in Chrome). Also, with the increasing sales of windows touch screen devices and adoption of IE10, touch input compatibility with IE seems like a valuable goal.
If anyone here is interested in providing feedback on the pointer events design, I'd encourage you to join the working group (or at least post your comments to public-pointer-events [4]). The most significant missing piece from the specification is a description of interoperability with touch events (similar to the section on mouse events [5]), but I'm optimistic there will be something reasonable here soon (Mozilla and Opera are both involved and so care about this issue too). Outside of the design details, are there any thoughts or concerns about WebKit getting an implementation of pointer events at some point?
