Patent application highlights Apple's continued flirtation with haptic feedback

We could all use a little feedback, right? Even Apple. The company has been toying around with the concept of haptic feedback for a while now, at least so far as patent applications are concerned. Another application filed in November or 2010 has surfaced. Of course, what we told you back in 2009 about the tenuous connection between an application and an actual product is as relevant as ever. Still, Apple's concept for a "tiered haptic system" which "may use one or more arrays of shape change elements to provide a wide range of tactile feedback" demonstrates that, at least as of late 2010, Cupertino was still working to rethink the way it sees touchscreens.
