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.
