    Ambient Assisted Living (AAL) offers possibilities for promising new IT-based health care services that are resulting in new challenges for its design process. We introduce a novel approach for engineering AAL services (AALSDA) which combines methods from service engineering and participatory design. We demonstrate this approach by developing and implementing an electronic data capture system, NuTrack, for self-reporting of nutrition status. The approach uses different concepts for AAL service design and delivery: service engineering for standardizing and structuring service processes, reasonable IT-support for automation of parts of services that need no person-to-person interaction, participatory design to integrate end-users in the development process, and patient integration for personalizing and improving the depth of performance of service providers' service delivery. For illustration, we present the case of chronic disease patients suffering from impaired fine motor skills. Our approach is applied in a pilot study with prototypes tested in focus groups and workshops with patients, caregivers and physicians. The results demonstrate good applicability and feasibility of the concept, and provide new insights for the future design, development and implementation of AAL services.

    Growing expenses for health care services in hospitals stress the potential of a well applied IT governance for cost reduction, productivity gains and a possible source for competitive advantages. The underlying explorative study analyzes the current status of IT governance through a survey among 206 IT decision makers in German hospitals. The quantitative analyses show that the most important requirements of IT managers for IT are the optimization and standardization of processes, that IT investments shift from administrative to medical IT applications, and that private hospitals display relatively higher IT budgets than do non-profit or public hospitals based on financial turnover. Further, two types of future IT decision makers are empirically identified. The types differ regarding their future role as initiators for process optimization and regarding the degree of involvement in strategic decision making.

    Patient data, particularly emergency data, must be available to medical personnel within a short time frame and independent of potential interruption of (mobile) network connections. Additionally, medical data is confidential information that must not openly be available to anyone with physical access to the storage media. The planned German electronic Health Card (eHC) is supposed to hold emergency data. However, the eHC smart card will not always be available to caregivers in emergency situations, e.g., unconscious patient, since it cannot be duplicated, customized or read without physical contact. We therefore propose the SemTag prototype which utilizes Near Field Communication (NFC) technology to provide secure and quick access to medical information. Caregivers have the opportunity to store encrypted medical data on tags for a particular group of addressees, e.g., for emergency cases in homecare environments. The tags can be placed on highly visible locations, e.g., entrance areas of homes and carried by the user inform of a token. Neither ubiquitous network access nor the unique eHC is necessary, to view emergency medical data within home care environments. Hence NFC tags can be regarded as a tool for information and identification alternative to distributed information systems for the collaboration of caregivers. This manuscript shows the technical storage and encryption process of emergency data on NFC tags. The technical feasibility, benefits, limitations and future research prospects of the prototype system are discussed.

    This study presents a novel approach towards establishing online social connections using Facebook and NFC-enabled mobile phones. There is increasing convergence between users’ real life social networks and their online social networks, with online connections following actual social acquaintance and interactions. Accordingly there is a need to provide users with means of accessing and establishing online connections in social networking platforms such as Facebook as and when they interact with other people in their real lives. The NFriendConnector is a prototype application which fulfills this functionality. This paper describes the design and development of the prototype application. The expectation confirmation theory is used to analyze the extent to which the NFriendConnector fulfills this inherent need among users and how this influences their intention to adopt and use the prototype. The proposed research model is tested in an experimental setup.

    Meditec is a German manufacturer of instruments for surgeries. The company is quality leader in this sector and supplies many German and international hospitals. However, the opportunities for differentiation against competitors decrease continuously. New competitors from emerging markets are challenging the market position of established companies in this industry. Meditec is therefore forced to change its strategy and business model in order to survive in this novel competitive environment. The management of Meditec has decided to traverse from a pure product manufacturer to a customer-centric solution provider. This transformation requires the development of new processes, competencies and capabilities – especially with respect to IT and IT services. This teaching case helps in understanding the role of IT in product-service systems (PSS) and PSS-based business models. Therefore the case illustrates why IT is necessary to establish a PSS-based business model and why a customer-centric view is important for this kind of business model.

    Social integration is crucial for the overall well-being of the elderly who are more prone to social exclusion because of the natural aging process. We propose online social networking as means to enhance social connectedness and social support – two aspects of social networks that have significant implications for the well-being of elderly. While prior research investigating the benefits of online social networking has primarily focused on user groups such as teenagers and college students, there is less understanding on how online social networks can be used to support and strengthen social ties among elderly. This study intends to investigate means of increasing social connectedness and social support among elderly through participation in online social networks, and the resulting implications on overall satisfaction with life. Our aim is to identify features of online social networks that cater to the specific social connectedness and support related requirements of elderly users.

    Traditional paper-based longitudinal or cross section panel surveys, used for market research are time and cost consuming and can suffer from contaminating effects like social desirability bias or respondent conditioning. Electronic data capture methods can improve the time and cost efficiency of market research panels. Radio Frequency Identification (RFID) technology allows a seamless and non-intrusive integration of information systems into everyday life environments. This enables the automated electronic acquisition of media usage data, without direct interference with the media consumption and thus without the contaminating effects of traditional panel surveys. Consequently, we introduce an RFID-based prototype system called MUSE (Media Usage in Supportive Environments) that supports automatic measurements of print media usage in public environments. MUSE was tested in an initial field study over the course of six weeks in the waiting room of a German medical practice. The study showed that MUSE could monitor the usage of print media, laid out for waiting patients, autonomously and with minimal errors. Furthermore, the RFID technology was perceived as nonintrusive. This study is the first to show how RFID enhanced real world settings can be used for nonintrusive media usage analysis in real life. Based on the findings we derive recommendations for future research for RFID supported media usage analysis.
