Abstract-Bringing heterogeneous devices like industrial machines, home appliances, and wireless sensors into the Web assumes the usage of well-defined standards and protocols. Our approach combines the Web Service standard for devices DPWS with the embedded system and component management standard OSGi. It implements the specifications of OSGi Remote Services, as well as OASIS Discovery, Eventing, SOAPover-UDP, and DPWS. Furthermore, runtime WSDL generation and interpretation is supported, as well as the presentation URL feature which automatically provides a web browser user interface for interactive device access. Thus, our approach is an appropriate and comprehensive basis for the seamless, flexible, and standard-compliant integration of things into the Web.
The project CordiAAL purposes the goal of developing a training system for patients with cardiovascular diseases. The first aim is to reduce the anxiety of overexertion by using a continuous monitoring of vital parameters and the second is to increase the patients' motivation according to a moderate physical activity by the virtual environment of the system. The training can be done alone or in common with several patients in a virtual group, regardless of the patients' location. When grouped together, the performance of the individual patient is aligned, so that patients with different fitness levels are able to work together. The evaluations revealed that the increase in motivation could be achieved by training in the virtual environment in virtual groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
