Abstract
University campuses, like many other public and private institutional settings, pose challenges to visitors and newcomers finding their way from place to place. In some cases, such campuses have grown to the size of a small town. Maps and tour guides have traditionally been the means used to assist visitors find their way; however, the recent development of high-power, low-cost mobile computing opens the door to portable electronic navigational aids. This paper focuses on user interface concerns in a personal digital assistant (PDA) based campus guide. Cognitive and visual display engineering principles are used to develop a preferred preliminary design. Subjective feedback and quantitative data on the user interface are gathered in a small pilot study. The appropriateness of the design and its implications for future work are also discussed.
