Developing mobile services for specific user groups using virtual environments

Specifying customized mobile and ubiquitous services for special needs group, such as the elderly is a difficult task. Customized services are needed to reflect different health care issues. To test and develop new customized mobile and ubiquitous services, a mixed reality virtual test platform is proposed. The architecture of the test platform combines real sensor data to obtain the context, with the RealXtend virtual environment. Specific user processes are defined using QFD which is also used in the development of appropriate services. This paper lays out the general architecture for the system, how real sensors interact with RealXtend and how the individual processes is discovered using QFD and RealXtend.
