[Show abstract][Hide abstract] ABSTRACT: The hospital and the health-care center of a community, as persons' life-care and health-care settings, need to provide more and better services for patients or residents. Establishing Electronic Medical Record (EMR) system is the necessity in hospital, and providing pervasive services is the further trend. Based on the EMR database, this paper presents a user-centric pervasive computing service model (PCSM) that coordinates application services over network and heterogeneous platforms nearby users to form a service environment for medical and health-care. It also provides doctors with legacy information service support without modification to exiting information system based on the PCSM.
[Show abstract][Hide abstract] ABSTRACT: As innovative technologies like ubiquitous computing and grid computing continue to emerge and become more popular, the amount of resource available on them has come to an extreme extend. However, traditional provider-centric resource sharing architecture focuses on defining service interfaces so that users must know exactly where and how to explicitly ask for resources. This method can not satisfy user's personalized task requirements. To solve the problem, this paper puts forward a user- centric resource sharing architecture which called U- RSA. The U-RSA mainly focuses on abstracting the currently personal computing environment from user's perspective. This paper also discusses the key technologies of our architecture.

Applications available for end-users have become increasingly abundant, distributed and heterogeneous in pervasive computing environment. How to share and utilize these applications is a significant research problem in pervasive computing environment. This paper puts forward a User-centric Applications Sharing Model (U-ASM). The U-ASM mainly focuses on abstracting the applications from service providers and end-users, and then utilizes virtualization technology to encapsulate applications and uses ontology organize distributed applications as a logic unit with semantic relationships so that it can provide better quality of service for end-users. The research result has been applied in R&D Infrastructure and Facility Development of Ministry of Science and Technology and has great flexibility and extensibility.
[Show abstract][Hide abstract] ABSTRACT: In pervasive computing environments, users can interact with a wide range of services, but which do not include legacy application services such as interactive desktop applications. How to use legacy service as a kind of transparent service mechanism in a pervasive computing environment is an important problem to solve during the transition from personal computing to pervasive computing. This paper presents a user-centric service framework that coordinates application services over network and heterogeneous networked devices nearby users to form a user's virtual computing environment. It also provides legacy support without modification to existing softwares based on virtual desktop and virtual device
[Show abstract][Hide abstract] ABSTRACT: This paper presents a ubiquitous computing technology called Virtual Personal Computing Environment (VPCE), which enables users to access their personalized computing environments anywhere using any available terminals. The key feature of the VPCE is that it can be constructed dynamically by reassembling application services and resources distributed over networks, which is different from the traditional desktop personal computing environment that is tied to an individual computer to execute. In VPCE, users work with a heterogeneous collection of application services, and data access by application as well as the application accessed by users are distributed over networks, while the applications and data distribution is transparent to the users.
