“Ubiquitous” has been the key buzzword in the research community as well as in everyday life these days. In Korea, ubiquitous become decorative words for many new products, which has not necessarily enough link to the world of ubiquitous. In research field, many public, private sectors research activities decorated with the word of “ubiquitous” has drawn so much attention, but still, little exa...

Technologies such as augmented Reality (AR), 3D Virtual Worlds (3DVWs) and mobile phones are extending education to other spaces beyond the classroom or the Virtual Learning Environments (VLEs). However, the richness of across-spaces learning situations that could be conducted in all these spaces is hampered by the difficulties (encompassed under the “orchestration” metaphor) that teachers face...

Wireless sensor networks (WSNs) enable smart environments to provide pervasive and ubiquitous applications, which give contextaware and scalable services to the end users. In this paper, an agent-based architecture is proposed for knowledge discovery and the variation in received signal strength indicator (RSSI) is used for knowledge extraction. Several experiments are conducted in an in-door e...

In this paper we present why tele-monitoring is a promising application domain for Ubiquitous Computing. We discuss how the characteristics of ubiquitous information systems can be applied in the design of tele-monitoring applications and what special conditions and problems have to be regarded. Finally, we present the results of the implementation of such an application realized in a joint res...

The ever-increasing rise in the number of chronically ill people is a growing burden on healthcare institutions. People with chronic illnesses such as heart disease, being among the leading causes for morbidity and mortality, need constant monitoring of their health conditions. Remote health monitoring of patients residing in their homes helps reduce healthcare costs. Current telemedicine solut...
