Location-Sensitive Services: It's Now Ready for Prime Time on Cellular Phones!

摘要

Today's wireless devices have the capability to receive information that is tailored to customers' needs at a particular location. A unique set of location-based services - called PNT and including user-solicited information, worldwide mapping, route guidance, positioning and ecouponing - has been created for tiny displays and limited input of mobile Internet-enabled cellular phones. A first version is available on an Ericsson R380s. A set of user interfaces has been designed. This makes finding information more intuitive than ever before: interfaces have been optimized for mobile use that demands not only quick and direct manipulation but also easy navigation.
