Alternative care environments for regular nursing homes are highly warranted to promote health and well-being of residents with dementia that are part of an age-friendly and dementia-friendly city and society. Insight is lacking on how to translate evidence-based knowledge from theory into a congruent conceptual model for innovation in current practice. This study reports on the co-creation of an alternative nursing home model in the Netherlands. A participatory research approach was used to co-create a conceptual framework with researchers, practitioners and older people following an iterative process. Results indicate that achieving positive outcomes for people with dementia, (in)formal caregivers, and the community is dependent on how well the physical, social and organizational environment are congruently designed. The theoretical underpinnings of the conceptual model have been translated into “the homestead,” which is conceptualized around three main pillars: activation, freedom and relationships. The Homestead Care Model is an illustrative example of how residential care facilities can support the development of age-friendly communities that take into consideration the needs and requirements of older citizens. However, challenges remain to implement radical changes within residential care. More research is needed into the actual implementation of the Homestead Care Model.

This paper reports on an architecture, and a working implementation, for using secondary screens in the interactive television environment. While there are specific genres and programs that immerse the viewer into the television experience, there are situations in which people perform as well a secondary task, whilst watching. In the living room, people surf the web, use email, and chat using one or many secondary screens. Instead of focusing on unrelated activities to television watching, the architecture presented in this paper aims at related activities, i.e., to leverage the user impact on the content being watched. After a comprehensive literature review and working systems analysis, the requirements for the secondary screen architecture are identified and modelled in the form of a taxonomy. The taxonomy is divided into three high-level categories: control, enrich, and share content. By control we refer to the decision what to consume and where to render it. In addition, the viewer can use the secondary screen for enriching media content and for sharing the enriched material. The architecture is validated based on the taxonomy and by an inspection of the available services. The final intention of our work is to leverage the viewers' control over the consumed content in our multi-person, multi-device living rooms.

Inclusion of content with temporal behavior in a structured documents leads to such a document gaining temporal semantics. If we then allow changes to the document during its presentation, this brings with it a number of fundamental issues that are related to those temporal semantics. In this paper we study modifications of active multimedia documents and the implications of those modifications for temporal consistency. Such modifications are becoming increasingly important as multimedia documents move from being primarily a standalone presentation format to being a building block in a larger application. We present a categorization of modification operations, where each category has distinct consistency and implementation implications for the temporal semantics. We validate the model by applying it to the SMIL language, categorizing all possible editing operations. Finally, we apply the model to the design of a teleconferencing application, where multimedia composition is only a small component of the whole application, and needs to be reactive to the rest of the system. The primary contribution of this paper is the development of a temporal editing model and a general analysis which we feel can help application designers to structure their applications such that the temporal impact of document modification can be minimized.

INTRODUCTIONIn the first generation of multimedia documents, the document format served as a simple transport wrapper for a byte stream of content. In the second generation, the document often contained additional temporal, styling and structuring primitive that allowed the transformation for interoperable playback on compliant multimedia players and some user interaction. In both cases, the multimedia content is dynamic, temporally and spatially constrained by the document, but the document itself is static: the relationships described by it do not change. Currently, multimedia documents are entering a new generation: the document is embedded as part of a larger application, where the content of the document may be adapted during rendering time, based on the needs and directives of the embedding application. These adaptations can change the underlying multimedia data, but also the general presentation structure. Examples of such applications include live editing of broadcast content [10] and interactive multimedia applications that make use of Web services [11]. In this paper, we use the term multimedia transformations to refer to the process of adapting various aspects of a multimedia document while it is playing.A representative example of dynamic multimedia applications is a video conferencing system that allows multiparty playing of an electronic board game [23]. The application needs to support multi-party social communication, guided by verbal and physical cues from users, as well as camera actions that are...
