One of the main gripes of the iPhone when first introduced was the lack of a physical keyboard which allowed for tactile feedback. This was very difficult to implement considering the iPhone utilized a touch screen which manipulated the keyboard, any sort of feedback was eliminated altogether. Malcolm Hall and Eve Hoggan, students at the University of Glasgow overcame this limitation and implemented a Haptic keyboard system.

Although the concept exists, the prototype is less than ideal due to the few bugs found that killed the demo experience. However, it is a big first step in the right direction despite this being a prototype. The concept is demonstrated in a text editor but cannot be enabled for other Apps such as Mail, Notes or even Safari.

For the daring, the Haptic demo can be downloaded here.
