Telemedicine creates virtual medical collaborative environments. We propose here a novel concept of virtual medical devices (VMD) for telemedical applications. VMDs provide different views on biomedical recordings and efficient signal analysis. In this paper we present a telemedical EEG analysis environment based on virtual reality technologies. The same(More)
In this paper we present a model-driven approach to content repurposing. Our work is inspired by the OMG's Model Driven Architecture (MDA). The MDA is an approach to system specification and interoperability based on the use of hierarchically organized formal models. The MDA approach uses a platform-independent base model (PIM), and one or more(More)
—In this paper, we show how spreadsheets, an end-user development paradigm proven to be highly productive and simple to learn and use, can be used for complex service compositions. We identify the requirements for spreadsheet-based service composition and present our framework that implements these requirements. Our framework enables spreadsheets to send(More)
There is a great variety of theoretical models of emotions and implementation technologies which can be used in the design of affective computers. Consequently, designers and researchers usually made practical choices of models and develop ad-hoc solutions that sometimes lack flexibility. In this paper we introduce a generic approach to modeling emotional(More)
While many multimedia systems allow the association of semantic annotations with media assets, there is no agreed-upon way of sharing these among systems. As an initial step within the multimedia community, we identify a small number of fundamental processes of media production, which we term canonical processes. We specify their inputs and outputs , but(More)
