A novel approach to performing unsupervised mobility assessment tests in domestic environments is presented. As a part of the aTUG concept the approach is based on the idea to segment assessment tests into components made up of recurring movement patterns which are measured independently by use of ambient sensor technologies. Quality criteria are defined which compute a score of eligibility for usage of sensor data to assess a certain test component. Valid component measurements are recombined to complete assessment tests according to a technical assessment test description defining the flow of segments and their constraints. An experiment has been conducted within a field trial with five elderly people aged 64-84 years over five weeks. The flats of all people were equipped with home automation (HA) sensors. A laser range scanner (LRS) was placed in one flat. Results from the fully-equipped flat show that the presented quality criteria are suitable to select LRS measurements according to their eligibility to assess a certain component. HA sensors and the LRS were used to compute a self-selected gait velocity of 0.71m/s unsupervised at home. TUG using the aTUG apparatus and a stopwatch was used as clinical reference data yielding a mean gait velocity of 1.18m/s. For the described setting a difference of 0.47m/s between capacity and performance in gait velocity was found.

The demographic change and the cost pressure in the healthcare sector drive the need for efficient and secure medical homecare solutions which apply for the people who are elderly or in anastasis. As the complexity of such systems is rising, there is a need of a common foundation of components which can be reused to lower the implementation effort of such systems. The European ITEA2 OSAmI research project targets such a common foundation of basic components for a basic, widely applicable service-oriented component platform. The German OSAmI-D subproject develops a construction kit based on the OSAmI component platform with a particular focus on services for medical and E-Health applications. The results of the ongoing project and especially the foundation of reusable components are demonstrated in the scenario of home-based ergometer training during the rehabilitation of patients with cardiologic illnesses.

In this paper conceptions and architectural considerations of the OSAMI project and their specializations towards the requirements of the e-health domain by the German subproject (OSAMI-D) are described. Along with the expected shift of healthcare service between stationary towards ambulatory care, a standardized way of integrating medical data acquired at home into the IT infrastructure of hospitals and the synchronization with medical workflows have to be implemented. Therefore, the OSAMI-D project will provide open source components that implement the required interfaces. Preliminary results of the requirements analysis and the implementation of first domain-specific services are presented. These services are used to realize two home care scenarios, which support ambulant cardiologic rehabilitation (indoor and outdoor). Special emphasis is placed on standards and formats for the communication and storage of patient data.

Providing health care and assistance at home becomes more and more important due to the aging society and - in general - a health system under financial pressure. It is generally accepted that these services have to be supported by an eHealth infrastructure that enables the exchange of patient related data between different health institutions and assistance systems athome (referred to by the term AAL). In this paper a service-oriented architecture for delivering eHealth / AAL services at home using a hardware platform such as a residential gateway or a set-top-box is proposedand exemplified by three different services: (1) telerehabilitation of patients after heard surgery, (2) support of hearing impaired people and (3) the monitoring of Activities of Daily Living (ADL).
