Extending Mobile Devices with Spatially Arranged Gateways to Pervasive Services
Workshop on Pervasive Mobile Interaction Devices (PERMID) in conjunction with Pervasive 2007, Toronto, Canada, May 2007. (bib)

Discovery and interaction with services is as much a user interface problem as a networking problem. In this paper we introduce a system in which mobile devices are seamlessly extended with Gateways to services in their environment. The gateways are realized as widgets that are arranged around the edge of the mobile devices user interface to indicate the direction of discovered services, thus providing the user with an overview of interaction opportunities. The gateways also afford direct access to services integrate with the devices interface, for example supporting dragand- drop of objects to a gateway and through the gateway to the corresponding service.
