Personal digital assistants (PDAs) combined with wireless networking are beginning to let mobile users access the same information they once used only from the office or at home. However, researchers have long realized that it's important not to treat mobile computing simply as a scaled-down version of desktop computing. Rather, mobility has profound consequences for the way in which we use computers. For example, desktop users might concentrate on a computer display for long periods, but mobile users are often mobile because they want to interact with the world around them. Consequently, a common situation when using a PDA to find information about our immediate environment is to continuously switch between looking around and looking at the PDA display.
