    A User Interface Concept for Context-Aware Recommender Systems
    (Mensch und Computer 2016 - Tagungsband, 2016) Hiesel, Patrick; Wörndl, Wolfgang; Braunhofer, Matthias; Herzog, Daniel
    A context-aware recommender system incorporates the knowledge of different contextual factors - such as time or weather information - to improve the item suggestions made to a user. While this provides great benefit to users, it might be hard for them to grasp why certain items are relevant, given the complexity of a context-aware recommender. In this paper, we propose, implement and evaluate a user interface concept that seeks to tackle this challenge. We show how popularity graphs can be used to inform the user about the relevance of items in different contexts and how users perceive different contextual factors given our concept. A user study with 14 participants demonstrates that our concept is valid and appreciated by users.

    Towards Model-based Development of Context-aware Augmented Reality Applications
    (Softwaretechnik-Trends Band 39, Heft 2, 2019) Yigitbas, Enes; Jovanovikj, Ivan; Sauer, Stefan; Engels, Gregor
    Augmented Reality (AR) is a technique that enables users to interact with their physical environment through the overlay of digital information. With the spread of AR applications in various domains (e.g. product design, manufacturing or maintenance) and the introduction of concepts such as Pervasive Augmented Reality (PAR), the aspect context-awareness started to play an important role. By sensing the user’s current context and adapting the AR application accordingly, an adequate user experience can be achieved. Due to the complex structure and composition of AR applications, their development is a challenging task. Although, context-awareness for AR systems was addressed to some extent, a systematic method for development of context-aware AR applications is not fully covered yet. Therefore, in this paper, we identify the main challenges for development of context-aware AR applications and sketch our solution idea for a model-based development framework
