    A Virtual Reality Simulator for Timber Fabrication Tasks Using Industrial Robotic Arms.
    (Mensch und Computer 2023 - Tagungsband, 2023) Bossecker, Eric;  Sousa Calepso, Aimée; Kaiser, Benjamin; Verl, Alexander; Sedlmair, Michael
    Virtual Reality (VR) simulators are well known applications for immersive spaces. When it comes to Human-Robot Collaboration(HRC), training and safety are important aspects that can be supported by simulators. In this demo, we propose a workflow between ROS and a VR application that allows the use of real robot programming plans to control the robot's digital twin. We also provide the results of a short evaluation that was done with 6 experts, where they provided insights for future improvement and use cases. Our demo is the first step towards a full integrated system where path planning and fabrication steps can be tested with users without any of the risk and cost that are involved when using real industrial robots.

    Züri teilt: Facilitating Resource Sharing Practices in Neighborhoods
    (Mensch und Computer 2023 - Tagungsband, 2023) Fedosov, Anton;  Ochsenbein, Lisa;  Mele, Ivan;  Oster, Robin;  Rivière, Maude;  Gisin, Ronny
    In the non-profit sharing economy context, an increasing number of resource sharing collectives and organizations (e.g., libraries of things) and peer-to-peer grassroots sharing initiatives leverage underutilized household resources (e.g., tools) to optimize their shared use for the benefit of their local communities. However, a number of social-technical challenges prevent the endurance and growth of such initiatives. Prior research highlighted the specific difficulties related to poor visibility of members’ activities and often high social barriers that hinder interactions among neighbors and strangers. In our prior work, stemming from our continuous engagement with one local sharing community in Switzerland over several years, through fieldwork, interviews, and co-creation studies, we elicited a set of design opportunities to address the emergent community's challenges. Based on these design considerations, we developed Züri teilt, a mobile application to facilitate resource sharing practices among neighbors aligning with the slow, temporal, and gradual nature of their relationships.

    Scalable Design Evaluation for Everyone! Designing Configuration Systems for Crowd-Feedback Request Generation
    (Mensch und Computer 2023 - Tagungsband, 2023) Haug, Saskia; Sommerrock, Sophia; Benke, Ivo; Maedche, Alexander
    Design evaluation is an important step during software development to ensure users’ requirements are met. Crowd feedback represents an effective approach to tackling scalability issues of traditional design evaluation methods. Crowd-feedback systems are usually developed for a fixed use case and designers lack knowledge on how to build individual crowd-feedback systems by themselves. Consequently, they are rarely applied in practice. To address this challenge, we propose the design of a configuration system to support designers in creating individual crowd-feedback requests. By conducting expert interviews (N=14) and an exploratory literature review, we derive four design rationales for such configuration systems and propose a prototypical configuration system instantiation. We evaluate this instantiation in exploratory focus groups (N=10). The results show that feedback requesters appreciate guidance. However, the configuration system needs to find a balance between complexity and flexibility. With our research, we contribute with a generalizable concept to support feedback requesters to create individualized crowd-feedback requests to support scalable design evaluation for everyone.

    Predicting Mouse Positions Beyond a System's Latency Can Increase Throughput and User Experience in Linear Steering Tasks
    (Mensch und Computer 2023 - Tagungsband, 2023) Wiese, Jannik; Henze, Niels
    Latency is present in all interactive systems and decreases user experience and performance. Previous work developed approaches that predict user actions and show these predictions to reduce latencies’ negative effects. While this can increase user experience and performance, it is unclear if predicting beyond a system’s latency results in further improvements. Therefore, we investigated the effects of predicting beyond a system’s latency. We collected data from 60 participants performing Steering Law tasks to systematically train an artificial neural network (ANN) that predicts 100ms into the future. We integrated the ANN into the Steering Law task and buffered users’ inputs to simulate latency between 50ms and -50ms. A study with 30 participants showed that decreasing latency beyond the system’s latency increases throughput up to -50ms. Subjective measures improved up to -16.67ms without negative effects on agency. Overall, we show that predicting beyond a system’s latency can increase performance and user experience.

    TrainOn: An Open Source Plugin for Developing Online Trainings and Conducting Studies in WordPress TrainOn: Ein Open Source-Plugin für die Entwicklung von Online-Trainings und Durchführung von Studien in WordPress
    (Mensch und Computer 2023 - Tagungsband, 2023) Mallwitz, Tim; Janneck, Monique; Sternitzke, Max; Mergan, Hamid
    Web-based platforms do not always offer the necessary prerequisites for the development and scientific monitoring of online interventions. Also, the use of these platforms is often associated with high licensing fees. This article presents TrainOn, an open source plugin for WordPress that can be used to create complex interactive online trainings as well as to realize online surveys and complex study designs.Webbasierte Plattformen bieten nicht immer die notwendigen Voraussetzungen zur Entwicklung und wissenschaftlichen Begleitung von Online-Interventionen. Auch ist die Nutzung dieser Plattformen häufig mit hohen Lizenzgebühren verbunden. Dieser Beitrag stellt TrainOn vor, ein Open Source-Plugin für WordPress, mit dem komplexe interaktive Online-Trainings erstellt sowie Online-Befragungen und komplexe Studiendesigns realisiert werden können.

    HoloBoard: A gamified balance board experience
    (Mensch und Computer 2023 - Tagungsband, 2023) Frölke, Robin; Benjamin, Butz; Lux, Gregor; Gerken, Jens
    In this demo, we present HoloBoard, a HoloLens2-based Augmented Reality application, which gamifies traditional balance board training to make it more engaging and enjoyable. Ankle injuries are among the most common injuries in many ball sports. Balance training, such as training programs which use a balance board, can help stabilize foot joints and prevent injuries. Traditional balance training is often inadequate because there is no feedback, and the "monotonous" movements are perceived as "boring". Our application is based on the Unreal game engine and utilizes the HoloLens2 to engage the player in various ball sports related game types such as catching, heading and dodging, thereby requiring various body movements similar to traditional balance board training programs.

    From ChatGPT to FactGPT: A Participatory Design Study to Mitigate the Effects of Large Language Model Hallucinations on Users
    (Mensch und Computer 2023 - Tagungsband, 2023) Leiser, Florian; Eckhardt, Sven; Knaeble, Merlin; Maedche, Alexander; Schwabe, Gerhard; Sunyaev, Ali
    Large language models (LLMs) like ChatGPT recently gained interest across all walks of life with their human-like quality in textual responses. Despite their success in research, healthcare, or education, LLMs frequently include incorrect information, called hallucinations, in their responses. These hallucinations could influence users to trust fake news or change their general beliefs. Therefore, we investigate mitigation strategies desired by users to enable identification of LLM hallucinations. To achieve this goal, we conduct a participatory design study where everyday users design interface features which are then assessed for their feasibility by machine learning (ML) experts. We find that many of the desired features are well-perceived by ML experts but are also considered as difficult to implement. Finally, we provide a list of desired features that should serve as a basis for mitigating the effect of LLM hallucinations on users.

    Participative Technology Development of ICT tools for Risk Communication and Disaster Management
    (Mensch und Computer 2023 - Tagungsband, 2023) Anniés, Jeannette;  Papathanasiou, Chrysoula;  Knudsen, Selby;  De Vito, Pietro; Sampson, Orestis; Michalis, Panagiotis; Karagiannidis, Lazaros; Amditis, Angelos; Barbagelat, Marco; Mandri, Eva; Ilengo, Gianluca; Ravizza, Daniele; Karaca, Fatmanur
    In the scope of the H2020 project RiskPACC, ICT tools are co-designed to be applied to the field of Disaster Risk Management (DRM). These tools follow the project's approach to enhance the communication between Civil Protection Authorities (CPAs) and citizens. This work accompanies two demonstration videos for the AEOLIAN AR mobile application and the Social Media platform HERMES. Both tools show novel approaches to enable end-users, such as citizens, to communicate with CPAs during all phases of DRM in a two-way communication flow. The tools have been co-designed during three rounds of targeted workshops with five organisations representing local authorities facing natural and anthropogenic hazards. Concluding the co-creation processes, the tools have improved to TRL6 (AEOLIAN) and TRL5 (HERMES). This work gives background information on the relevance, development, and main features of the solutions.

    Interactive Soundscape Tabletop to Promote Immersive Sound Experiences for People Living With Dementia and Their Caregivers
    (Mensch und Computer 2023 - Tagungsband, 2023) Held, Patrizia;  Röhrl, Florian; Schnell, Norbert
    Music interventions have been proven effective in activating people living with dementia, even in the advanced stages of the disease. Alongside music, sound-based activities are vital for the care of those affected. However, the use of sound-based activities in the daily care of people living with dementia is challenging and lacks research. To address this gap, sound-related interactive media can play a significant role. Currently, existing systems rarely allow individuals with dementia to create personalized sound experiences. In the DIDEM project, we are exploring digital solutions in a participatory development process to improve everyday sound experiences for people with dementia. In this demonstration, we introduce a prototype of an interactive soundscape tabletop designed specifically for collaborative activities with people living with dementia within institutional settings.

    VRoom – Development of a Virtual Reality learning environment for the utilization of color in an architectural context
    (Mensch und Computer 2023 - Tagungsband, 2023) Reckter, Holger;  Lüttich, Thomas
    Usage of Virtual Reality (VR) applications in an education setting has specific needs. The high number of parallel users create atypical time and space requirements. Interaction with the system needs to be intuitive, easy to learn and quick to understand. While intuition is approachable in simple applications, with an increasing system complexity this principle is becoming harder to implement. In the development of VRoom we used a User Centered Design approach. Regarding the process we used informal tests and implemented different methods of user interaction in VR. We examined different placements and alignments of the User Interface (UI) elements. Depending on the qualitative user feedback the functionality of the VR application was adapted and resulted in a combination of different UI elements with the goal to learn the utilization of color in different interior environments.
