    The main challenge addressed by CloudTeams is bridging the communication and collaboration gap between software developers and end users throughout the whole software development process in order to develop better software. CloudTeams solves the problem by bringing together software developers and end users into one platform, thus providing a seamless environment where interaction with customers will feel natural and will validate the software product. It integrates popular software development tools and services by mashing them up with common practices. A sustainable community of end users provides their activity data through their avatars to the development teams at any stage of the software development cycle, from idea generation to beta testing.

    Position paper: Tools for the development of accessible and interoperable services for the Web of Things

    The Web of Things is about extending the Internet of Things [Ashton 2009] concept beyond the connection of things and considering issues like heterogeneity, scalability and usability with respect to progressive computing [Mayer et al. 2013]. By introducing web technologies, the concept overpasses Machine-to-Machine (M2M) communication and incorporates interaction with users into the landscape. Until now, there is not a lot of research in this domain on developing accessible applications for people with special needs. This position paper presents our initial approach to define and implement a semantic web-based framework for interoperable and accessible services in the Web of Things, which extends previous work of the authors for web 2.0 applications.

    The development of products that are accessible to the largest possible group of users can be regarded as a major challenge for manufacturers of consumer products. It is therefore crucial, that the product development process is supported by practical methods and tools that can help incorporate these essential human factors in early phases of the development process. Ergonomic evaluation and user testing with real users are user centred design methodologies often conducted by companies that are not only complex, but can be very time and cost-intensive. As an alternative approach virtual user models (VUM) have been proposed for supporting the early phases of the product development process. In this paper we will present the modelbased design approach of the European research project VICON s upporting inclusive design of consumer products particularly at the early stages of product development.

    From keyword extraction to key action extraction

    In this paper, we present a new approach where we apply text mining approaches from computational linguistics to identify key action within usage data. The key actions identify the more relevant activity patterns of a learner and thereby provide information on the learning goals and its current status. This information is being used for self-directed learning approaches.

    The dataTEL white paper develop during the dataTEL workshop at the ARV2011. The workshop was motivated by the issue that very less educational datasets are publicly available in TEL, so that the outcomes of different TEL adaptive applications and recommender systems that support personalised learning are hardly comparable. In other domains like in e-commerce it is a common practise to use different datasets as benchmarks to evaluate recommender systems algorithms to make the results comparable (MovieLens, Book-Crossing, EachMovie dataset). So far, no universally valid knowledge exists in TEL on algorithm that can be successfully applied in a certain learning setting to personalise learning. Having a collection of datasets could be a first major step towards a theory of personalisation with in TEL that can be based on empirical experiments with verifiable and valid results. Therefore, the main objective of the dataTEL workshop was to explore suitable datasets for TEL with a specific focus on recommender and adaptive information systems that can take advantage of these datasets. In this context, new challenges emerge like unclear legal protection rights and privacy issues, suitable policies and formats to share data, required preprocessing procedures and rules to create sharable datasets, common evaluation criteria for recommender systems in TEL and how a dataset driven future in TEL could look like.

    Utilizing cell phones for bystander intervention during emergencies

    Due to the ubiquity and ever-increasing capabilities of cell phones, they have been exploited for mobile data collection in diverse domains [1]. In this position paper, we hypothesize that bystanders can contribute to the handling of emergencies by means of usage of smart phones. To examine our hypothesis, we conducted at first 24 interviews, as described in [2]. Time staggered we also interviewed two persons who experienced the crisis at a stampede [3] at the Love Parade music festival in Germany in the year of 2010. Based on the results of both studies, we draw conclusions for the design of a potential mobile emergency app being dedicated for bystanders.

    Widget user interface considerations for ROLE widgets
    ( 2011)
    Wolpers, Martin
    ;
    The development of computer-based learning environments aims to create a truly personal and individual learning experience. A learning environment should be self explaining and easy to use. Thus, the design and development of the user interface plays a major role in the learning experience. Furthermore, personal learning environments (PLEs) provide the learner with the ability to build their own learning environments by compiling respective services, contents and peers. In this context, the European project ROLE focuses on the development of an architecture to enable learners to compile their learning environment within the browser using widget technology. In this paper, we briefly discuss the suggestions and best practices of the ROLE project for the design of widget interfaces to run wit hin the ROLE enabled PLEs.
