Apple patents another haptic feedback solution

AppleInsider reports that Apple is still bouncing around ideas for a screen that allows for haptic feedback on its iOS devices. A new patent filed this week outlines a system of screens on a device designed to not only detect touch and protect the underlying technology but also provide physical feedback in various areas of the screen.

We've talked about this before, and Apple's been working on it for a while; as nice as the iPhone and iPad's screens are, there are some functions (like typing on a keyboard or hitting buttons in games) that call for a little more physical feedback. The patent also mentions things like giving users notice when they've reached a limit (as in scrolling or panning across pictures) or providing clicks on a scroll wheel.

Unfortunately, this is all still in the prototype stages. For whatever reason (I can guess a few, from power requirements to manufacturing costs), Apple still hasn't included any of this technology in a production device. But they're obviously very interested in providing haptic feedback, so hopefully, it won't be too long before we see an idea like this come to fruition.
