Abstract

Big challenge related to the contemporary research on ubiquitous and pervasive computing is that of seamless integration. For the next generation of ubiquitous and distributed applications to emerge, disruptive functionality towards opportunistic and heterogeneous device ensembles is required on all levels of operation. In this paper, we present middleware-level resource management service for situated displays in public smart spaces, acting as a scheduler and an arbiter for mobile clients. From this service, we focus on multidimensional resource discovery, which facilitates mobile users in locating and deploying situated displays in public and semi-public smart spaces. Dimensions for discovery include dynamic availability of the displays in both spatial and temporal scales, user and rolebased access control, as well as the support for intended service. We have implemented the discovery service and subjected it for alpha testing in an indoor setting. We report a proof-of-concept implementation of the ScreenSpot system and demonstrate an approach of visualizing the discovery results to the user.
