Alternate technology that could take games to the next level

blueBook

Gaming potential
For an RPG a blueBook could take the place of your character's spell book. When you want to cast a spell, you press a selection of arcane words or quaint antique symbols. There's massive potential for blueBook within military simulations, too. How about a paper map, where you can mark waypoints in the game by tapping on the map? And why not replace old piracy prevention codewheels with a blueBook? Press the following four letters to prove you're not a dirty code-thief.

It's an obvious addition to simple teaching games too: give a child a book with cows and sheep, where pressing on a cartoon bovine brings up a video of the real thing. Everyone likes cows, right?
