Most of us don’t like touchscreens because of their lack of tactile feedback and this Nokia concept tries to fix this issue with a small pump, that fills the buttons with a liquid, so the user can feel it. Actually, this might be a great idea, but currently we probably don’t have the necessary technology to do that, so the concept will remain a concept for a long time or even forever. Still, it remains a great idea and it would improve the touchscreens considerably.
