The use of Augmented Reality glasses opens up many possibilities in hospital care, as they facilitate treatments and their documentation. In this paper, we present a prototype for the HoloLens 2 supporting wound care and documentation. It was developed in a participatory process with nurses using the positive computing paradigm, with a focus on the improvement of the working conditions of nursing staff. In a qualitative study with 14 participants, the factors of autonomy, competence and connectedness were examined in particular. It was shown that good individual adaptability and flexibility of the system with respect to the work task and personal preferences lead to a high degree of autonomy. The availability of the right information at the right time strengthens the feeling of competence. On the one hand, the connection to patients is increased by the additional information in the glasses, but on the other hand, it is hindered by the unusual appearance of the device and the lack of eye contact. In summary, the potential of Augmented Reality glasses in care was confirmed, and approaches for a well-being-centered system design were identified but, at the same time, a number of future research questions, including the effects on patients, were also identified.
Playful Co-Design: Creating an AR-Prototype with Nurses in Interlocking Remote and On-Site Workshops
(2023)
Deeply engaging nurses in a participatory co-design process, especially in times of COVID-19, is challenging. In this case study, we shed light on the process of developing a prototype for AR-glasses in nursing. We show the challenges we faced, the methods we used and how they contribute to the core principles of participatory design. A special focus is laid on small-scale interventions with high-impact, that helped us to truly engage users. We introduce empathetic ways to connect contrasting work environments, establish mutual understanding, make the abstract more graspable with playful tools like PLAYMOBIL®, and support co-design development with online formats. Finally, we discuss the transferability to other projects.
The nursing profession is becoming increasingly complex: administrative and nursing tasks have to be performed in parallel, under time pressure and in shifts. These stressful working conditions also affect safety-critical processes such as the correct dispensing of medication. As digitization continues, new technologies such as augmented reality (AR) glasses are emerging that offer potential solutions. However, a practical implementation requires a deep understanding of the underlying problem and user needs. The aim of this paper is to first, discover pains and gains in the process of medication dispensation and second, develop a conceptual prototype for AR glasses as a basis for discussion on the applicability in practice. A participatory design process with nursing professionals and experts from technical and organizational fields was established. As result, we present a conceptual prototype, that (A) respects the context of use, (B) guides users while dispensing medication according to prescription, (C) displays useful information about medical preparations, procurement of alternate medicine and dosage variations and (D) uses checklists and error recognition to increase safety. Multidisciplinary feedback workshops indicate an overall positive resonance. We advise paying attention to the spatial and economic situation while using AR as a support tool providing flexibility for users.
We present a study on the usability of three different user interfaces for an augmented reality glasses system. The application is intended for use in hospitals by nursing professionals. During wound care, images can be taken with the Microsoft HoloLens 2 and measured directly. The photos must always be taken at the same distance from the wound to follow the healing process. We present and juxtapose three aim assistants to take a picture of the wound and acquire wound data. To gain a first impression about the goodness of usability and the preferred targeting assistant, we conducted a small usability study. Participants were asked to perform wound measuring tasks using our application’s varying user interfaces. In this study, we identified strengths and weaknesses for each user interface based on the conducted research and identified approaches for further improvements.
