Touching invisible buttons floating in the air may seem strange, but so-called spatial computing is a new way of interacting with cars, games and even touchscreens.

Many devices with resistive touchscreens also include a stylus for more precise pointing.

The potential of graphene is practically unlimited. It can be used in cancer therapy, in flexible touchscreens, or for batteries that will charge in seconds.
