We at Nokia have implemented tactile feedback (i.e. Haptics) support for
touch-based user interfaces and are now ready to land the implementation to
the WebKit trunk. Since the real-time requirements of a realistic feel are
very tight, it is not possible to implement the haptic feedback via a simple
javascript event handler. We have considered various alternatives and
concluded that the best and most future-proof way is to utilize CSS to
specify the tactile feedback style of a web element.
Thus, we implemented a -webkit- CSS extension that enables web developers to
specify the feel of an element. This is important for custom JavaScript
controls to behave identically to native controls. The specification is
currently at http://www.starlight-webkit.org/CSS/css3-haptics.html and the
implementation work is ongoing at
https://bugs.webkit.org/show_bug.cgi?id=40263. We have also been discussing
about this at www-style mailing list to get feedback.
We are actively driving the standardization with the Nokia standardization
team and will make any necessary changes of the final standard, if any. As it
is likely that this extension will be used mainly by JavaScript libraries, we
are not too concerned about the potential legacy the standardization may
introduce.
Finally, the haptic feedback of web elements will be implemented in Nokia
smartphones and we would like to commit the implementation to the open source
even before product launch. All feedback would be more than welcome!
My impression from the thread on www-style (starting here
http://lists.w3.org/Archives/Public/www-style/2010Jun/0389.html) was that
there was very little consensus over the haptic feedback-related CSS
properties. I think it's premature to land an implementation in WebKit until
the specification has been more widely discussed, and has a greater degree of
acceptance.
