    Global versus Regional User Requirements for the Vehicle HMI
    (Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Menrath, Iris; Wagner, Verena; Wolter, Stefan; Becker, Stefan
    Based on global product development, unification of HMI concepts in the automotive sector plays an important role. To understand the scope of the HMI globalization or the need for regional adaptations, several investigations with participants from China, North America and Europe have been carried out. Different display aspects like color and labels were tested with the help of flash animations, computer simulations and prototype components. The results show that for color a global HMI solution can be found, whereas for item labels regional differences do exist.

    Integrated HMI Concept for Driver Assistance and Automation
    (Mensch und Computer 2016 – Workshopband, 2016) Brockmann, Martin; Allgaier, Angela; Timofeev, Michael; Becker, Stefan
    The present study describes the development of an integrated ADAS HMI concept within the European-funded research project interactIVe, its implementation and user-centred validation in a driving simulator. The HMI concept integrated visual, haptic and acoustic information-, warning- and intervention (IWI) strategies, and allowed the driver to select between three different assistance and automation levels. The concept was implemented in the fully interactive Ford HMI driving simulator and was validated in an empirical user study with N=24 participants. The vast majority of the sample was positive about the idea of integrated assistance functions integrated in three selectable modes. Good comprehensibility and learnability of the mode selection concept could be proven. The visual display concept with safety zone segments around the vehicle - representing the safety-shield metaphor - was positively recognized. User feedback and observation results also revealed some weaknesses in system usability. Detailed suggestions for improvement could be derived.

    ODRL 2.0 revisited
    (INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Becker, Stefan; Hück, Benjamin; Naujokat, Katharina; Schmeiser, Arne Fritjof; Kasten, Andreas
    The Open Digital Rights Language (ODRL) is one major rights expression language which has been in development since 2001. ODRL allows to define policies which describe who is allowed to do what with a good. Despite its long history, ODRL 2.0 still has some drawbacks concerning the syntax and semantics of its entities and relations. This paper presents the results of an in-depth analysis of these shortcomings and outlines possible solutions. These include proposals to simplify the Core Model of ODRL to be better understood by new users as well as to prepare ODRL for the usage with encodings other than XML.
