Apple patent application reveals tactile-feedback keyboard

With Apple tablet rumors mounting and anticipation causing its market share to rise, it looks like there is still more innovation to be uncovered. Apple filed a patent application called “Keystroke Tactility Arrangement on a Smooth Touch Surface” which entails a dynamic surface that changes depending on how a user interacts with it. In order to keep a smooth surface while pointing and swiping, like on the iPhone, and getting some ridges or bumps on the surface for typing, the surface of the screen would have to physically change depending on use. So, when you’re just pointing on the screen, there are no bumps — type on the screen and bumps appear.

Another patent application called “Multipoint Touch Surface Controller” will allow greater flexibility with multi-touch systems. The patent says:

While virtually all commercially available touch screen based systems available today provide single point detection only and have limited resolution and speed, other products available today are able to detect multiple touch points. Unfortunately, these products only work on opaque surfaces because of the circuitry that must be placed behind the electrode structure.

Apparently, removing the limitations of an opaque surface would allow for better speed and accuracy, as well as the ability to detect more contact points on the screen. So, with better multi-touch technology and possibly a surface that reacts to how you use it, future Apple products, like a tablet, could see a huge leap forward with regards to how we interact with touch screen devices today.
