    Automation and its Effects on Mental Workload in Industrial Sectors
    (Mensch und Computer 2024 - Workshopband, 2024) Staab, Verena
    Automation technology has profoundly transformed modern life, promising further evolution in safety and efficiency. However, it also fundamentally alters work dynamics, notably in the maritime sector where automation is increasingly prevalent. This dissertation investigates how automated systems impact mental workload and human-technology interactions in maritime contexts. By adapting a framework based on cognitive load theory, it analyzes predictors (e.g., automation, system design, level of autonomy, individual differences) of mental workload through systematic reviews and experimental studies. Key challenges include recruiting specialized maritime participants and deploying equipment in operational settings. By addressing these challenges, the dissertation aims to enhance understanding and implementation of automation, offering practical insights for optimizing human-technology interfaces in maritime automation.

    Digital Human Modeling for Design and Evaluation of Human-Machine Systems
    (MMI Interaktiv - Human: Vol. 1, No. 12, 2007) Naumann, Anja; Rötting, Matthias
    Digital Human Modeling is an emerging area that bridges computer-aided engineering design, human factors engineering and applied ergonomics. Especially for ergonomics questions, digital humans are already being used. The paper describes different fields for the application of digital human modeling in product design, assembly and manufacturing. Current research on digital human modeling in training, risk assessment of workplaces, hand-object interaction, modeling eye movement, and the assessment of comfort is highlighted. The case is made for a combination of anthropometric models and cognitive models. In addition, the consequences of a wider application of digital human modeling in product design, assembly and maintenance are discussed, especially with regard to the education of engineers and human factors specialists.

    Examining Joy of Use and Usability During Mobile Phone Interactions within a Multimodal Methods Approach
    (Mensch und Computer 2022 - Tagungsband, 2022) Lingelbach, Katharina; Tagalidou, Nektaria; Markey, Patrick S.; Föll, Bettina; Peissner, Matthias; Vukelić, Mathias
    Objective: We investigate experienced joy of use (JoU) and usability using a multimodal methods approach by systematically varying mobile phone interactions. Methods: We combined subjective and objective measures to investigate whether positive emotional experiences and moments of joy during the interaction can be distinguished from neutral and negative emotional experiences. In a study with 30 participants, electroencephalography (EEG), electrocardiography (ECG), electrodermal activity (EDA), facial emotion recognition, and questionnaires were used. Results: There were greater positive experiences in interactions designed to elicit JoU, even under bad usability. We did not observe a difference between the conditions in the EEG indices. However, a higher heart rate and components in the EDA phasic response as well as facial muscle activity associated with anger were linked to good usability combined with no JoU. Conclusion: The multimodal methods approach reveals great potential to investigate JoU and usability in naturalistic scenarios. Application: The developed framework provides a groundwork to evaluate and improve interactions with technology. Thereby, users and their emotional experiences are placed at the centre when designing user interfaces. By detecting moments of joy, this approach can support a better understanding of how technology can be purposefully designed for joyful experiences.

    Is There Anything Else...?" Role-Play Exploration To Use Response Times As A Relationship-Building Effect With Voice Assistants"
    (Proceedings of Mensch und Computer 2024, 2024) Schäfer, Antonia; Freyer, Mark Jonathan
    The rapid advancement of language models is driving significant developments in voice assistants, enabling tasks to be performed without graphical or tactile user interfaces and fundamentally changing human-machine interaction. This article explores interaction with intelligent voice assistants (IVA) to improve usability and user experience. The focus is on designing the interaction between question and answer in the response time. The study demonstrates the effectiveness of the role-playing method in testing machine interactions in an accessible way, leading to the development of sound interactions. Furthermore, the study shows that the latency of a response can be divided into three distinct phases that can be deliberately designed. Additional findings indicate that the use of acoustic feedback and clear signals reduces uncertainty and enhances perceived response time.

    Safety-Critical Personality Aspects in Human-Machine Teams of Aviation
    (i-com: Vol. 15, No. 3, 2016) Eschen, Solveig C. S.; Keye-Ehing, Doris; Gayraud, Katja
    Working safely and successfully in highly automated human-machine interfaces of future aviation is not only a matter of performance, but also of personality. This study examines which personality aspects correlate with safety-critical performance in human-machine teams. The research tools HTQ (Hybrid Team Questionnaire) and HINT (Hybrid Interaction Scenario) were combined for a comprehensive exploratory study. The HTQ includes personality scales measuring broad factors of personality (Big Five) as well as more specific scales and was added with objective personality assessments to measure risk taking. The simulation tool HINT simulates relevant processes in future human-machine team interaction in aviation. In a study with 156 applicants for aviation careers, safety-critical relations of some facets of general personality as well as risk taking were found. Especially personality aspects concerning disinhibiting, spontaneous behaviour and sensation seeking show correlations with poorer performance in the HINT simulation.

    Towards Human-Robotic Collaboration: Observing Teamwork of Experienced Surgeons in Robotic-Assisted Surgery
    (Mensch und Computer 2022 - Tagungsband, 2022) Cypko, Mario A.; Timmermann, Lea; Sauer, Igor M.; Müller-Birn, Claudia
    Current robotic systems in surgery are telemanipulators, but the future will likely be more automated. Past and current developments literally put the robotic system at the center of the action, and force the surgical team to adapt to it. In addition to important advantages of robotic surgery, empirical studies identify serious disadvantages in sensory perception and team communication, leading to decreased situational awareness among the surgeon and the team. We therefore raise two interrelated questions: Which actors of a surgical team should be part of a controlled, semi-automated robotic assistance and how should the collaborative interaction between the actors (including the robot) be designed. Previous research has examined the situation awareness in robotic-assisted surgeries with bedside assistant, being either residents or specifically trained registered nurse first assistants, with advantages of one over the other. We built on this work by observing for the first time robotic-assisted surgeries with highly experienced bedside assistants, senior surgeons. We found that a senior surgeon in this role excelled once again, for example, through lively medical discussions and independent problem solving, and was more likely to give us clues about a thoughtful development of semi-autonomous, collaborative surgical robots. These new insights will form the basis for subsequent interviews in which surgical teams will reflect on their expectations of the robotic agency. Our overarching goal is then to translate the results into new user interface designs for robotic surgery through repeated cycles of participatory design workshops and expert evaluations.
