Creating video games pushes the state-of-the-art in computer interface designs. The video game environment requires the computer to process a wide range of input devices and compute the appropriate audio, video, and tactile user feedback. Processing has to be fast enough to introduce no perceptible delays to the player. The user interface extends beyond the mechanical processing of inputs and outputs. The game player doesn't want to be conscious of "using a computer" but rather is stepping into a story. The fact that computer technology is used in creating the play field, refereeing the game, and often is the actual opponent must be hidden by using some of the best tricks in story telling, game theory, and the field of human development psychology. The presentation will cover progress in the video game area from the early days at Atari to the latest simulator games.
