Healthcare costs in the US are approximately 15% of GNP and are anticipated to reach 17% of GNP in the near future. Management of chronic diseases via technology based ubiquitous patient monitoring services has been widely proposed as a viable option for economizing healthcare resources, and providing efficient, quality healthcare. The process of ubiquitous patient monitoring is information int...

NEC’s Activities for Developing Business Solutions and Technology Needed for a Ubiquitous Society By Yutaka KASAHARA* and Keiji YAMADA† This paper describes the prospect of a ubiquitous society and the concept of the ubiquitous system on which it is based. Integrating ubiquitous networks and ubiquitous computers, the system, will provide many application services, some of which are introduced i...

A significant increase in real world event monitoring capability with wireless sensor networks brought a new challenge to ubiquitous computing. To manage high volume and faulty sensor data, it requires more sophisticated event filtering, aggregation and correlation over time and space in heterogeneous network environments. Event management will be a multi-step operation from event sources to fi...

A dramatic increase of event monitoring capabilities by wireless sensors requires new, more sophisticated, event correlation over time and space. This new paradigm implies composition of events in ubiquitous computing environments and event Correlation will be a multi-step operation from event sources to final subscribers, combining information collected by wireless devices into higher level in...

This paper presents ActivitySpot, a ubiquitous computing framework for supporting localized activities, i.e., activities strongly associated to a specific physical environment, performed by occasional visitors. The ActivitySpot framework implements an activity-centered approach to ubiquitous computing, by defining a conceptual model inspired by Activity Theory and implementing a software infras...

This paper presents a study of the comparison of different healthcare services to identify the characteristics and of a pervasive and ubiquitous healthcare system which is described as the healthcare provided for home based and moving patients that could enable remote and continuous monitoring and medical services anywhere and anytime. The study has identified the different classification of he...

Ubiquitous computing means network connectivity everywhere, linking devices and systems as small as a drawing pin and as large as a worldwide product distribution chain. What could happen when people are so readily networked? This paper explores issues arising from two possible emerging models of ubiquitous human computing: fungible networked brainpower and collective personal vital sign monito...

Information technology is an integral part of daily life in many domains, including communication, computing, entertainment, and education. However, despite its pervasiveness, digitalization in various purposes and application in many human-based activities, it still plays the role of assisting and supporting people in manipulating and acquiring information. This study developed a ubiquitous le...

With the great progress of technologies, computers are embedded into everywhere to make our daily life convenient, efficient and comfortable. In the learning field, ubiquitous technologies make it possible to provide services to learners anytime and anywhere in the real world. In this paper, we present an ubiquitous environment to support college students, professors, and visitors in a laborato...
