The paper addresses the problem of how to make a human–computer interaction user-friendlier within a problem solving environment (PSE). Pre-operative planning of a vascular reconstruction procedure is a case study for this research. The Virtual Radiology Explorer (VRE) presented in the paper has being deployed for the virtual reality (VR) and desktop projection modalities. Both projection modal...

∗ This research is conducted while the author was with CAIP Research Center, Rutgers University, New Brunswick, NJ. Abstract Collaborative services and applications are becoming increasingly important and complex and have requirements for real-time multimedia support, high bandwidth availability, and low delays. The collaborative application view of QoS encompasses transport network, end system...

We introduce EasyEx, a recommendation-based book exchange system which identifies potential exchanges for a user solely based on the user’s item list. EasyEx is novel, since it effectively identifies books that are likely appealing to users, and optimizes book-exchange cycles to increase serendipity, instead of simply swapping books on users’ wish lists as performed by existing item-exchange al...

Introduction. In this paper we propose a multi-agent Selective Dissemination of Information service to improve the research community's access to digital library resources. The service also provides a new recommendation approach to satisfy researchers' specific information requirements. Method. The service model is developed by jointly applying Semantic Web technologies (used to define rich des...

Computing environments of the future should satisfy two competing requirements: first, users should be able to take full advantage of the capabilities, devices and resources available at each location. Second, users should be free to focus on their real tasks, rather than being distracted by dealing with the configuration and reconfiguration of computer systems to support those tasks. Unfortuna...

Reconsidering IT usage as part of a cultural phenomenon drives us to envisage the development of a new instrument to assess the construct of Individual IT Culture (IITC). IT-culture is a concept which has started only recently to appear in IS literature. Grounding our research in psycho sociology and the theories of needs and motivation, which have considerably evolved in the last two decades, ...

Past research suggests Facebook use is linked to perceptions of social capital, a concept that taps into the resources people gain from interactions with their social network. In this study, we examine a sample of public Facebook status updates (N=20,000) for instances in which users request a response from their network. These attempts to mobilize resources offer insight into the mechanisms th...
