    DriveAssist - A V2X-Based Driver Assistance System for Android
    (Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Diewald, Stefan; Möller, Andreas; Roalter, Luis; Kranz, Matthias
    In this paper, we introduce the Android-based driver assistance system DriveAssist. The application allows the visualization of traffic information that originates from Vehicle-to-X (V2X) communication services as well as from central traffic services (CTSs) on the user’s smartphone. Besides giving the driver an overview of the traffic around her/him on a map view, DriveAssist can also run in the background and trigger warning messages for certain traffic incidents. The system design allows for augmenting any vehicle with a sophisticated audio-visual information system for V2X data and information, and thereby complements the vehicle’s on-board driver assistance systems at competitive costs.

    M3I: A Framework for Mobile Multimodal Interaction
    (Mensch & Computer 2014 - Tagungsband, 2014) Möller, Andreas; Diewald, Stefan; Roalter, Luis; Kranz, Matthias
    We present M3I, an extensive multimodal interaction framework for mobile devices, which simplifies and accelerates the creation of multimodal applications for prototyping and research. It provides an abstraction of information representations in different communication channels, unifies access to implicit and explicit information, and wires together the logic behind context-sensitive modality switches by a rule-based approach. In this paper, we present the structure and major features of our framework, and show exemplary implementations of interaction modalities with help of M3I.

    Simulation and Digital Prototyping of Tangible User Interfaces
    (Mensch & Computer 2014 - Tagungsband, 2014) Diewald, Stefan; Möller, Andreas; Roalter, Luis; Kranz, Matthias
    Physical prototyping is an important part in research and development of tangible user interfaces (TUIs). On the way from the idea to a working prototype, hardware prototypes usually have to be crafted repeatedly in numerous iterations. However, this can be very time- and cost-intensive when non-standard, expensive hardware components are part of the design. This brings us to think about digital prototypes that exhibit the same functionality as a physical TUI, but reduce the amount of resources that have to be spent. For that reason, we present a middleware-based process that allows developing and testing fully functional implementations of a tangible user interface as a digital device in a 3D virtual environment.

    The Healthcare and Motivation Seat - A Survey with the GewoS Chair
    (Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Roalter, Luis; Linner, Thomas; Möller, Andreas; Diewald, Stefan; Kranz, Matthias
    The demographic change in the world’s population raises new problems for healthcare, such as rising costs for caretaking on elderly people. Ambient Assisted Living (AAL) aims at assisting elderly people through technical equipment to manage their daily tasks in their own homes. One of the important approaches is to monitoring vital parameters without actually sending nursing staff to the person in need of care. Additionally, by including motivational factors (e.g. sports and fitness programs), the person’s health state can be influenced. In this paper, we present a survey within a group of elderly people aged between 40 and 70 years, which is representative for the end-user group the GewoS Chair is designed for. Furthermore, we will discuss the elderly people’s behavior when dealing with new technologies and systems improving further attempts on this target group.

    Today, you walk! – When Physical Fitness Influences Trip Planning
    (Mensch & Computer 2014 - Tagungsband, 2014) Diewald, Stefan; Möller, Andreas; Roalter, Luis; Kranz, Matthias
    Technology-based self-tracking of physical activity is a new trend. However, monitoring one’s own behavior does not automatically motivate one to increase physical exercising. For that reason, we propose a concept that uses the tracked data for providing fitness routes in everyday trip planning, which are tailored to the users’ needs, personal preferences, and fitness levels. We argue that utilizing the monitored data for directed exercising during daily routines can add value to the quantified-self movement.
