Human computer interaction in the year 2000

Much of the work in the field of computer human interaction consists of finding out what is wrong with existing interfaces or which of several existing alternatives is better. Over the next few decades, the possibilities for computer human interaction will explode. This will be due to: 1) continued decrease in the costs of processing and memory, 2) new technologies being invented and existing technologies (e.g., handwriting recognition, speech synthesis) being extended, 3) new applications and 4) new ideas about how people can interact with computers. While changes along these lines are bound to occur, we need not take the view that investigators in human-computer interaction are to be passive observers of some uncontrolled and uncontrollable evolution. Indeed, we can help steer this process by visions of what the future of human computer interaction could and should be like.
