    Ein AAL-Projekt aus sozio-technischer Sicht: Erkenntnisse und Anforderungen
    (Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Prilla, Michael
    Dieser Beitrag beschreibt Ergebnisse des Projekts service4home, in dem mit Pen&Paper-Technologie Dienstleistungen für Senioren bereitgestellt wurden. Er diskutiert diese Ergebnisse aus der Perspektive sozio-technischer Phänomene und beschreibt Anforderungen aus dieser Perspektive, die bisher im Bereich AAL zu wenig beachtet werden.

    Adjusting AR-Workflows of Care Tasks: Experiences from an Initial Study
    (Mensch und Computer 2019 - Workshopband, 2019) Janssen, Marc; Prilla, Michael
    Professional caregivers need to adhere to standards when treating their patients in order to ensure a certain level of quality and hygiene. Whenever standards are refined or changed, caregivers must keep pace with them. However, these standards are interpreted differently by care providers and also offer degrees of freedom which enable caregivers to adapt them in certain situations and according to their own experience and practice. Workflows are a useful tool to define, share and execute standards correctly. In this paper we investigate the possibility to adjust workflows with our Care Lenses, an Augmented Reality based tool, which can be used by caregivers during the execution of care tasks and which supports them with guidance regarding standards. We show how care practice influences the development of technical support for workflows and what kind of advantages the possibility of adjustments grants to workflows and the integration into practice.

    Augmented Living: Einsatz von Augmented Reality im Alltag
    (Mensch & Computer 2014 - Workshopband, 2014) Ksoll, Michael; Prilla, Michael; Rashid, Asarnusch; Herrmann, Thomas; Merkle, Nicole
    Augmented Reality (AR) ist im Bereich des demografischen Wandels eine Form der Mensch-Technik-Interaktion, welche dazu beitragen kann, älteren Menschen intuitive und im Alltag integrierte Mensch-Technik-Benutzerschnittstellen zu bieten und diesen damit den Zugang zu digitalen Medien zu erleichtern. Bisherige Arbeiten adressieren eher ein junges Zielpublikum und fokussieren sich auf einzelne Anwendungsfälle. Das Projekt Augmented Living geht der Frage nach Einsatzmöglichkeiten und Grenzen von AR zur Unterstützung älterer Menschen in ihrem Alltag bzw. dem generations-übergreifenden Zusammenleben nach. In dieser Arbeit präsentieren wir den Zwischenstand im Projekt und stellen den Stand der Forschung, die identifizierten Anwendungsfälle und die Methodik zur geplanten Analyse von Einsatzpotentialen, Benutzerakzeptanz, Erfolgsfaktoren und Best-Practices vor.

    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.

    Augmented Reality Guidance for Car Repairs: immediate and long-term Effects
    (Mensch und Computer 2021 - Tagungsband, 2021) Hoffmann, Clemens; Prilla, Michael; Wundram, Kai; Emmermann, Björn
    Car service technicians are challenged by the increasing variety and complexity of repair and maintenance tasks. Recent studies have shown benefits by using augmented reality (AR) for different industrial tasks. Most studies compared a very established support technology with the new AR support in just one initial exposure. The lack of routine in dealing with AR often creates a respective disadvantage. This paper looks into the question to which extent can AR head-mounted display (AR HMD) guidance provide benefits for an unknown car repair task. To investigate further than an initial exposure, the service technicians repeated the specific task every twoweeks in total four times. The experiment under field conditions compares the efficiency, the repair quality, and the mental effort under AR HMD support to the traditional repair guideline. Results indicated that AR HMD support impacts positive the repair quality immediately and long term. Furthermore, the AR HMD support created a decent learning environment, that the high quality also remained without AR guidance. This shows opportunities to use AR HMDs for training and guidance of industrial tasks in practice.

    Combining Web 2.0 and Collaboration Support Systems
    (Mensch und Computer 2008: Viel Mehr Interaktion, 2008) Prilla, Michael; Ritterskamp, Carsten
    In the current discussion of the impact Web 2.0 may have on CSCW and Groupware research, Web 2.0 applications are often considered to be a substitute for Collaboration Support Systems. This paper argues that rather than replacing such systems, Web 2.0 mechanisms may complement them and help to overcome existing problems. The paper provides an analysis of differences and overlaps in purposes of applications and processes in these domains. This leads to the development of strategies for their combination. The paper describes real world implementations of these strategies and reflects upon how Web 2.0 may influence and even shape next generation Collaboration Support Systems.

    Computer-Supported Cooperative Work: Kooperation von Mensch zu Menschen, Mensch zu KI und Roboter∗
    (Mensch und Computer 2024 - Workshopband, 2024) Gross, Tom; Prilla, Michael
    Das Ziel dieses Tutoriums ist die Vermittlung von grundlegenden Paradigmen und Konzepten der Rechnergestützten Gruppenarbeit. Darauf aufbauend wird auf aktuelle Entwicklungen im Bereich kooperativer Systeme mit Virtual Reality und Augmented Reality eingegangen. Es werden aktuelle Trends im Bereich der computer-gestützten Kommunikation und Kooperation mit KI-Systemen sowie der Mensch-Roboter-Interaktion beleuchtet. Dieses Tutorial wurde bereits mehrfach erfolgreich auf Mensch & Computer Tagungen und internationalen Tagungen angeboten und wird laufend aktualisiert.

    Designing Augmented Reality Workflows for Care Specific Tasks
    (Mensch und Computer 2021 - Tagungsband, 2021) Janßen, Marc; Droste, Alexander Volker; Prilla, Michael
    Augmented Reality Head Mounted Devices have the potential to provide digital information to people while they are working. Besides other advantages, this enables the provision workers with instructions how to carry out certain tasks both for training and while they are working on the task. While using HMDs for the purposes has been shown to be beneficial in practice, the creation and adaptation of instructions and corresponding workflows is still a manual, time-consuming task. In this paper, we present a tool that enables the modelling and HMD specific configuration of such workflows, and that automatically instantiates these workflows on HMDs. This provides opportunities for creating user-specific workflows on HMDs and to adapt existing workflows to the needs of users. We illustrate the potential of our solution by the example of workflows in care.

    DigiCare — Co-Creation of an eHealth application for Cancer Patients
    (Mensch und Computer 2024 - Workshopband, 2024) Söhngen, Yannic; Prilla, Michael
    In this paper, we describe what the BMBF-funded research project DigiCare is and how we want to co-create an eHealth application for cancer patients. We start by describing why such an application is important and needed. Then, describe the process of the creation of our personas and how users are integrated into the development of the app from the beginning. At the end, we give some ideas from our workshops on why the involvement of patients in particular was important.
