The term Interface as related to this class most likely refers to the notion of a user "Interface." A user interface consists of both an input and an output, but refers in total to the collective means of human interaction with machines, computers, or other complex devices. The interface allows humans to manipulate a complex system which they otherwise could not operate. Computer keyboards are an example of a Graphical Interface, where input entered through the keys produce a visual output on the monitor. Tangible Interfaces, place more emphasis on physical interaction within the environment. New video game Interfaces emerging today are constantly working to alter our engagement with gaming software. The Nintendo Wii is an example of how a user interface often times is more crucial to an experience than is the actual software. As interfaces evolve, the interactivity of human beings with technologically advanced systems will increase our ability to experience technology in entirely new ways.
