Abstract
Communication at the human-computer interaction level, is discussed. The presentation layer, or user interface, to computer programs acts as a shield to a far more complex array of processes. Using simple navigational and functional commands, the user can manipulate a computer program and achieve desired results quickly. This is not always the case, however, and deficiencies in both usability and information access continue to plague ordinary computer users. With increasing public reliance on computer-generated information, powerful computer applications must be amenable to nontechnical users. The most commercially viable and prominent of these efforts are explored, with particular emphasis on the evolving role of artificially intelligent technologies.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
