Computerworld: "There is a lot of confusion between pervasive or ubiquitous computing on the one hand and human-centric computing on the other. They are not the same. Pervasive computing implies a lot of equipment, where the focus is on a lot of devices that are themselves computers. Human-centric computing, however, focuses on the human. Today, computers are hard to use. If we make them more pervasive and use more of them, there will be that much more aggravation around us. By focusing on human-centered systems, we declare that our goal is to serve humans. Whether that calls for more or less stuff is secondary." (2001-05-13)
