    We present the design artifact Travel Safety, a mobile travel risk information system (IS). Besides offering general travel risk information, the iPhone application leverages social media, in particular Twitter, to source travel risk information from multiple foreign offices. This provides a comprehensive real-time information base for the application and enables dispatch of automatic travel warnings. On the basis of Travel Safety we want to explore if content from social media can be leveraged to increase the attractiveness and usage of applications. Furthermore, we want to understand critical success factors in the context of using social media content. Travel Safety was evaluated in a large field study with 422 participants. The study reveals that applications can indeed successfully be enriched by social media content. However, our results also reveal that a fully automated sourcing of social media content without human content management bears significant challenges.

    Indoor room-climate influences our everyday life on many levels. High room temperature decreases our productivity and our ability to concentrate. Moreover, many medical conditions can be traced back to bad indoor room-climate. In this paper we present an information system (IS) for room-climate monitoring. Our system is an informative art system being equipped with standard room climate sensors for temperature, humidity and carbon dioxide. In contrast to conventional monitoring systems a display embedded in a standard art frame presents the current room climate on the basis of classical art. Changing room conditions are reflected in the painting in real-time. By implementing the presented IS we pursue a research avenue which is dedicated to a more fundamental research questions: "Are hedonic, art-based IS superior to utilitarian, non-art-based IS in respect to usage and impact?

    Large amounts of energy are wasted because heating systems run round-the-clock even though residents are out or occupy only a small part of their home. Major reasons for this behaviour are the non-intuitive heating controls and missing direct feedback about the heating activity or even energy consumption. In addition, bad ventilation behaviour, e.g. tilted windows, may lead to unhealthy room climate as well as significant heat losses. To address these problems, we analysed the requirements for a supporting information system. We present a first prototypical implementation of an individual-room heating and ventilation system which combines automation, an intuitive user interface and supporting feedback. This should empower residents to achieve energy-efficient heating and improved comfort.
