This should be a "new feature request" of course - sorry for the wrong type.
New issue 35 by kdekoo...@gmail.com: Add accelerometer / gyroscope support
http://code.google.com/p/gwt-mobile-webkit/issues/detail?id=35
Although not (yet) part of the HTML 5 spec it is possible to detect
accelerometer / gyroscope events in JavaScript. It would be great if there
was a GWT wrapper for this.
More info on how it can be done:

Oh and the sample site is awesome: http://isthisanearthquake.com/.
