    Augmented reality glasses for the crafts sector - acceptance factors for tasks with highly variable workspaces
    (Proceedings of Mensch und Computer 2024, 2024) Gutzmann, Jan Christoph; Dossena, Gian Luca; Prilla, Michael
    This study explores the acceptance of augmented reality (AR) head-mounted displays (HMDs) in enhancing support for the crafts sector. In a qualitative field study with three craft companies from different sectors, it was found that AR holds the potential to improve time efficiency, task learnability, and hands-free operations, fostering better problem-solving and information change. The framework for data analysis was based on the Unified Theory of Acceptance and Use of Technology 2 (UTAUT-2) model. However, we also found that challenges such as the fragility, bulkiness and cost of current HMDs, along with characteristics of the crafts sectors such as widely changing locations such as lighting and spatial conditions, hinder widespread adoption. The study highlights the need to enhance factors that promote acceptance and address those that inhibit it.

    The Impact of Smart-glass-based Video Tutorials on Knowledge Transfer in Practice
    (Proceedings of Mensch und Computer 2024, 2024) Gümüs, Esra; Gutzmann, Jan Christoph; Büttner, Sebastian Thomas; Prilla, Michael
    Video tutorials are an effective method of knowledge transfer and learning. However, they are often time-consuming to create and difficult to access during work. This paper introduces an approach that simplifies the creation of video tutorials in the workplace and promotes their use during work. By utilizing smart glasses, practitioners can record video tutorials during their daily work processes and utilize them for knowledge transfer to other employees without much additional effort. This offers the advantage of directly and easily sharing expertise in the workplace without being constrained by time or location. Given the intended simplicity of this approach, the question arises whether it creates video tutorials that help people in their learning. The paper presents a study that compares the effectiveness of knowledge transfer using these video tutorials against traditional personal training methods in the workplace. With 18 participants from the nursing and production sectors, we observed the training and learning outcomes of using video tutorials on smart glasses over multiple sessions, comparing them with personal training, which is considered the standard for practical onboarding. The study results indicate that learning with video tutorials does not significantly differ in terms of learning outcomes from traditional personal training methods. Overall, this study highlights the potential of video tutorials with smart glasses for knowledge transfer in workplaces, while also identifying challenges and opportunities for optimizing onboarding processes for employees.
