ABSTRACT
Interface” can mean many things—a game controller, a display device, a system of manipulating a virtual character, the way the game communicates information to the player, and many other things. To avoid confusion and to understand it properly, we need to separate it out into component parts. Information flows in a loop from player to game to player to game, round and round. It is almost like this flow pushes a waterwheel that generates experience when it spins. One kind of interface that tends to be associated with juicy fun is the touch interface found on phones and tablets. Touch interfaces have done a lot to change the world of gaming in a very short time. Young children, in particular, seem to take to touch interfaces with surprising ease. One important goal of any interface is to communicate information.
