Touch/Feel Screen

The major problem with touchscreens is that you can't feel the boutons that you are pushing. So as a result you have to always be looking at the screen when you're typing and it is easy to push a wrong bouton. This is very annoying if you are trying to multitask. Researchers at Carnegie Mellon University have realized this and have make their own touchscreen. This touchscreen is very unique because it can change it's shape to form boutons that you can push. This design is very simple and can only form certain limited bouton shapes.
