    Bridging the Energy Literacy Gap
    (Mensch und Computer 2024 - Workshopband, 2024) Michahelles, Florian; Kassem, Khaled
    This work presents a prototype, built from multiple hardware components and equipped with a user interface, designed to enhance energy literacy, facilitating better understanding and informed energy decisions that can drive policy changes. We showcase the prototype and discuss its integration into broader energy strategies.

    Enhancing the Supervision of Out-of-View Robots: A Study on Multimodal Feedback and Monitoring Screens
    (Mensch und Computer 2023 - Tagungsband, 2023) Kassem, Khaled; Shahu, Ambika; Tüchler, Christina; Wintersberger, Philipp; Michahelles, Florian
    Objective: investigating the effect of two support methods (multimodal feedback, monitoring screens, and a combination of both) on human dual-task performance, cognitive workload, and user experience when supervising an out-of-sight autonomous robot. Method: A 2x2 within-group user study was conducted in VR with 26 participants involving a cognitive-cognitive dual-task setting. Participants had to simultaneously solve math problems and supervise the robot. Different support methods were provided: multimodal feedback, a screen showing real-time robot activity, and a combination of both. Objective performance metrics and subjective feedback on cognitive load and user experience were collected using standard questionnaires. Data were statistically analyzed, and thematic analysis was performed on post-study debriefing interviews. Results: The support methods improved overall user experience and positively impacted robot collaboration performance while decreasing math task performance. Cognitive load was unaffected. Multimodal feedback with a monitoring screen was perceived as the most helpful. Conclusion: The results suggest that multimodal feedback can improve user experience and improve supervision, but may partially decrease primary task performance. The findings highlight the importance of examining the effect of support methods in specific situations, depending on task priority.

    Exploring Human-robot Interaction by Simulating Robots
    (Mensch und Computer 2022 - Workshopband, 2022) Kassem, Khaled; Michahelles, Florian
    As collaborative robots enter industrial shop floors, logistics, and manufacturing, rapid and flexible evaluation of human-machine interaction has become more important. The availability of consumer headsets for virtual and augmented realities has lowered the barrier of entry for virtual environments. In this paper, we explore the different aspects of using such environments for simulating robots in user studies and present the first findings from our own research work. Finally, we recommend directions for applying and using simulation in human-robot interaction.

    Push Me: Evaluating Usability and User Experience in Nudge-based Human-Robot Interaction through Embedded Force and Torque Sensors
    (Proceedings of Mensch und Computer 2024, 2024) Kassem, Khaled; Saad, Alia; Pascher, Max; Schett, Martin; Michahelles, Florian
    Robots are expected to be integrated into human workspaces, which makes the development of effective and intuitive interaction crucial. While vision- and speech-based robot interfaces have been well studied, direct physical interaction has been less explored. However, HCI research has shown that direct manipulation interfaces provide more intuitive and satisfying user experiences, compared to other interaction modes. This work examines how built-in force/torque sensors in robots can facilitate direct manipulation through nudge-based interactions. We conducted a user study (N = 23) to compare this haptic approach with traditional touchscreen interfaces, focusing on workload, user experience, and usability. Our results show that haptic interactions are more engaging and intuitive but also more physically demanding compared to touchscreen interaction. These findings have implications for the design of physical human-robot interaction interfaces. Given the benefits of physical interaction highlighted in our study, we recommend that designers incorporate this interaction method for human-robot interaction, especially at close quarters.

    Robots for Public and Social Spaces - Design for Intent Communication, Collaboration and Acceptance
    (Mensch und Computer 2023 - Workshopband, 2023) Häkkilä, Jonna; Kassem, Khaled; Kirjavainen, Emma; Kraus, Johannes; Michahelles, Florian; Müller, Heiko; Pfleging, Bastian; Seyffer, Norman; Trost, Kai Erik
    Intent communication is crucial for human-robot interactions, allowing robots to understand and respond to human intentions and enabling humans to comprehend potentially autonomous robots’ intentions. Social robots have become increasingly popular in various fields, from healthcare to education, due to their ability to interact with humans naturally and intuitively. Enabling seamless communication between robots and humans is a key challenge in developing effective social robots. This workshop explores the intersection of intent communication and user experience in social robotics, with a focus on human-centered human-robot interaction.The workshop aims to bring together researchers, developers, and practitioners from academia and industry to discuss recent advances in intent communication and user experience design in social robotics. Participants can present their research, share experiences, and engage in interactive discussions with other attendees. The workshop provides a forum for collaboration and knowledge exchange to advance the state-of-the-art in social robotics and HRI. This is the second iteration of the RoboX workshop at MuC.
