    “I Want My Control Room To Be. . . ”: On the Aesthetics of Interaction in a Safety-Critical Working Environment
    (Mensch und Computer 2022 - Tagungsband, 2022) Flegel, Nadine; Pöhler, Jonas; Van Laerhoven, Kristof; Mentler, Tilo
    Control rooms are safety-relevant working environments characterized by complex IT infrastructure. With regard to the interaction of operators with control room systems, usability has been the major criteria for decades. However, there is increasing discussion about the extent to which the concept of user experience (UX) also plays a role in such safety-critical contexts. What is still largely missing is the application of concrete UX-specific methods in the context of control rooms. This paper explains how and with what results 9 operators used an interaction vocabulary focusing on pragmatic and hedonic qualities to complete the sentence “I want my control room to be. . . ”. Results first suggest that pragmatic, i.e., usability-oriented, attributions are of greater importance to operators. However, especially the more UX-specific terms of the interaction vocabulary, which were initially not found to be so relevant, yielded many valuable hints and inspiration for the future design of control room workplaces. By reflecting on the process of discussing the aesthetics of interactions in such a safety-critical working environment, recommendations are provided for considering UX in safety.

    Investigating Cognitive Load in Emergency Control Room Simulations
    (Mensch und Computer 2023 - Workshopband, 2023) Pöhler, Jonas; Vitt, Antonia; Flegel, Nadine; Mentler, Tilo; van Laerhoven, Kristof
    We propose a novel approach to measure cognitive load in emergency control room operators using their breathing patterns. By using LstSim, a community-driven emergency control room simulator, we aim to recreate the work environment of a dispatcher, induce a cognitive load, and measure the response in the user’s breathing. Participants were monitored and recorded through wearable sensors, depth cameras below the screens, and simulation-internal parameters and interactions. The participants’ breathing patterns were analyzed to identify changes in breathing amplitude in response to varying levels of cognitive load. The results of our study provide compelling evidence that a simulated control room environment is successful in inducing cognitive load on participants shown in a significant increase in NASA TLX scores as well as a 13% increase in breathing amplitude. Despite the challenges posed by this individual variability, our findings also highlight the potential of using breathing as a real-time, noninvasive measure of cognition in control rooms. This has significant implications for the design and operation of emergency control rooms, potentially leading to the development of more responsive systems that adapt to the operator’s cognition load, thereby enhancing performance and effectiveness.

    Use Cases and Design of a Virtual Cross-Domain Control Room Simulator
    (Mensch und Computer 2022 - Workshopband, 2022) Mentler, Tilo; Flegel, Nadine; Pöhler, Jonas; Van Laerhoven, Kristof
    Control rooms are facilities of central importance in many safetycritical domains (e.g., rescue services, traffic management, power supply). At the same time, they are characterized by a complex IT infrastructure that can only be integrated and adapted to a limited extent for research activities in the area of human-computer interaction. Previous work has already shown that virtual reality simulators of control rooms can be a suitable tool for these purposes. However, the solutions to date are very domain-specific, which makes it difficult to transfer knowledge and also to test aspects that are not primarily domain-specific (e.g., multimodal forms of interaction). This paper presents the concept of a domainindependent control room simulator and the development status regarding two use cases (build mode, simulation mode). Finally, further development and use of this approach are discussed.

    What is a control room? In search of a definition using Word Embeddings
    (Mensch und Computer 2024 - Workshopband, 2024) Pöhler, Jonas; Flegel, Nadine; Mentler, Tilo; Van Laerhoven, Kristof
    Definitions are hard. But they provide valuable insight into the subject at hand. This paper presents a comprehensive analysis of the term "control room" using word embeddings to provide a nuanced definition. The study leverages the ACM Digital Library to compile a corpus of texts related to control rooms, generating word embeddings to capture semantic relationships. Key aspects identified include the physical space, ergonomic design, multimodal information presentation, warning systems, contextual awareness, and command functions of control rooms. The analysis also explores adjacent clusters, highlighting tactile interfaces, interactive surfaces, and the use of large displays to enhance operator performance and situational awareness. The findings underscore the technological, ergonomic, and operational dimensions critical to the definition and functionality of control rooms.
