    Evaluation of Online Consulting Using Co-browsing: What Factors Are Related to Good User Experience?
    (Springer, 13.06.2019) Christ, Oliver; Mutuura, Kamalatharsi; Papageorgiou, Andreas; Ahram, Tareq; Falcão, Christianne
    Technological advancements have changed many, if not all industries. This paper focuses on changes for service providers. Many services have been implemented without the knowledge about their effectiveness and user acceptance. This paper evaluates a web browser-based support framework for banks that provides customers with assistance through text chat and co-browsing.

    Immersive virtual reality during work out with movable sports equipment: the effect on oculomotor, disorientation, and nausea before and after training
    (AHFE Open Access, 2023) Christ, Oliver; Deuber, Michelle; Gächter, Anina; Guedel, Jordin; Papageorgiou, Andreas; Ahram, Tareq; Taiar, Redha
    The combination of immersive virtual reality and sport has garnered significant attention in the academic world and the industry domains. There is a decent amount of literature that shows positive effects but also critical voices when it comes to learning and wellbeing in a virtual world during work out. In our study we postulate the hypothesis that subjects with a higher degree of predisposition in simulation sickness will show higher values in all three subscales of the simulation sickness questionnaire (SSQ) while doing exercise with sports gear with moveable parts in a fully immersive VR application than subjects with lower degrees of predisposition in motion sickness. However, our data did not support the hypothesis. Surprisingly, we even found a disproportionate significant improvement in the oculomotor subscale of the SSQ. These results are being discussed and further studies are being suggested.

    Social Robots: Development and Evaluation of a Human-Centered Application Scenario
    (Springer Nature, 2019) Schulze, Hartmut; Kaufmann, Kaspar; Ziakas, Eleni; Catanzariti, Marco; Stoppa, Giancarlo; Burkhard, Roger; Tanner, Alexandra; Ahram, Tareq; Taiar, Redha; Colson, Serge; Choplin, Arnaud
    This study aimed to develop and evaluate an application scenario for the use of a social robot, following a human-centered design approach. The social robot, which assisted the reception desk staff of a hotel by answering simple, repetitive and time-consuming questions (e.g. parking information, directions), was perceived predominantly positive by employees and guests of the hotel. However, the results suggested that to effectively reduce the employees’ workload and to provide a reliable source of information for the guest, the robot had to work on a high level of autonomy and technological stability. Additionally, the use of a social robot may estrange guests and employees alike, as they prefer human interaction or are fearful of job loss, respectively. An early inclusion of the employees in the design process has shown to reduce fears and increase acceptance towards the social robot and its integration into the workforce.

    Symbols and Functions in Human Machine Interface: Are Google Icons a Possible Solution for Intercultural Usability?
    (Springer, 03.04.2020) Christ, Oliver; Papageorgiou, Andreas; Mutuura, Kamalatharsi; Ahram, Tareq; Taiar, Redha; Gremeaux-Bader, Vincent; Aminian, Kamiar
    We explored the possibility of taking icons from Android Smartphones, for the use in graphical user interfaces (GUI) in bakery sheeter. This idea was generated from the fact that Android Smartphones are sold worldwide and that the icons used in the menu should have a degree of popularity that most people could deal with. With this research question in mind we created a mixed method design for the study (qualitative and quantitative data). Results show that some icons were able to represent basic navigation function in industrial machines.

    Training in Immersive Virtual Reality: A Short Review of Presumptions and the Contextual Interference Effect
    (Springer, 03.04.2020) Christ, Oliver; Ziegler, Cyrill; Hirschi, Andreas; Genovese, Rosina; Papageorgiou, Andreas; Ahram, Tareq; Taiar, Redha; Gremeaux-Bader, Vincent; Aminian, Kamiar
    The increase of shipped consumer immersive virtual reality (IVR) up to 6 million units in 2019 shows the increasing popularity of this medium. Invests of 8 billion dollars are anticipated in the next five years for the training sector. With the development the question arise, what effects and advantages can be expected using IVR in human training? This paper reviews three important areas, when it comes to the design of immersive virtual reality trainings: 1. cognitive load, 2. spatial imagination and the contextual interference effect.
