Progress in mobile devices, wireless networks and context-aware technologies are bringing pervasive healthcare into reality. With the help of wireless PDAs and portable computers, people may enjoy high quality care from a well-orchestrated team of healthcare professionals in the comfort of their own homes. The main technical challenges include mobility, adaptability, privacy, access authorizati...

Pervasive computing is allowing healthcare to move from care by professionals in hospital to self-care, mobile care, and at-home care. The pervasive healthcare system, CARA(Context Aware Real-time Assistant), is designed to provide personalized healthcare services for chronic patients in a timely and appropriate manner by adapting the healthcare technology to fit in with normal activities of th...

This paper proposes a Human-centered Pervasive Computing System Model (HPC), a Layered Architectural Analysis and Design Method (LAAD) and a Waterfall Prototyping Process Model (WPP). Based on the HPC model and the LAAD method, a pervasive computing based multimodal tele-home healthcare system is designed and partly implemented using the Waterfall Prototyping Process. The design and implementat...

Using a pervasive healthcare system as example, a new approach to specification of user requirements for pervasive IT systems is presented. A formal modelling language, Coloured Petri Nets, is applied to describe what we call Executable Use Cases, EUCs. EUCs are precise, detailed, and executable descriptions of future work processes and their computer support. In particular, EUCs allow user req...

With the brilliant advance of ubiquitous technologies, it is possible to provide more smart and pervasive healthcare services in a smart home environment. Despite of these remarkable advances of technologies, there are few smart home-based personalized healthcare services which fully consider not only user’s current situation but also user’s social relationship. In this paper, we try to model c...

P ERVASIVE healthcare may be defined from two perspectives: first, as the application of pervasive computing—or ubiquitous computing, proactive computing, ambient intel-ligence—technologies for healthcare, health, and wellness management; second, as making healthcare available everywhere , anytime—pervasively. Essentially, pervasive healthcare addresses those technologies and concepts that inte...

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...

The technology needed to realize the goal of fully pervasive and mobile computing is rapidly coming together. Its emergence represents an unprecedented opportunity to expand the power of the Internet beyond traditional computing devices, enabling a world of smart spaces and smart appliances providing often invisible support for a variety of context-aware services with tremendous environmental a...
