Abstract
As global positioning, wireless communication, and mobile display technologies continue to advance, our notion of place will change. Information objects-first geocoded signs and later animated special effects-will begin to populate real physical space on what we call WorldBoard channels. WorldBoard is a proposed global infrastructure to associate information with places and ultimately to provide people with enhanced information perception services. This paper explores the notion of a WorldBoard from four perspectives: historical background, technical feasibility, potential applications, and social implications. Recent developments, ranging from lower-cost Global Positioning System (GPS)-enabled car navigation systems to Casio Electronics' first-of-a-kind GPS-enabled wristwatch, foreshadow increased availability of location-aware information services and products. While significant technical, application development, and social challenges remain before a complete WorldBoard infrastructure can be made broadly, uniformly, and cost-effectively available, some feasible first steps toward this important goal are recommended. Finally, a notion like WorldBoard offers an opportunity to reflect on how technological possibilities unfold.
