    Current teleconsultation solutions for preclinical emergencies can transmit knowledge from a remote expert to a local paramedic using audio and 2D video channels. Such technology lacks precision and efficiency for medical diagnostic tasks, and visual feedback is often missing between participants. We investigate a mixed reality 3D teleconsultation solution for preclinical use, which provides a 3D reconstruction of the local scene to a remote expert, displayed in Virtual Reality. A remote expert can join the local scene virtually as an Augmented Reality avatar. The remote expert can annotate the local scene and guide the local paramedics through the procedure. We explored our system in a user study within a preclinical scenario on a collaborative task of attaching chest lead electrodes of a 12 channel electrocardiogram on a mannequin. We compared the 3D teleconsultation system to a 2D video-mediated teleconsultation via a top-mounted camera and report results from the consultee side in AR. Based on our empirical user study with 10 paramedics with an average of 17 years experience, we observe an improvement in the electrode placement quality using the 3D teleconsultation system. Results indicate no significant difference in the cognitive task-load between conditions. Participants perceived the video-mediated consultation as more usable due to their unfamiliarity with the 3D teleconsultation system. However, participants acknowledge the potential of 3D teleconsultation and believe such a system can significantly improve the preclinical treatment.

    Requirement analysis for an AR-based teleconsultation system
    (Mensch und Computer 2019 - Workshopband, 2019) Budde, Vanessa; Reichling, Julia; Kraetsch, Clemens
    Due to demographic changes, a lack of medical expertise in special and rare cases may occur. One possible solution to overcome this deciency is the use of a teleconsultation system. This system makes it possible to remotely connect a medical expert. New technology developments, like AR- technologies, enable advanced and new applications of those systems. The present paper describes the results of expert interviews regarding attitudes towards and requirements on an AR-based teleconsultation system for telemedicine. The interviews were conducted with emergency doctors and paramedics already using an existing consultation system for telemedicine. Our aim was to gain insights into their attitudes towards and experiences with the current system, their requirements on an AR-based teleconsultation system as well as their attitudes and valuations towards the use of an avatar within such a system. Another focus of our study was on their estimation of the inuence of such a system on the patient-paramedic-interaction. The interviews were recorded, transcribed and analysed using qualitative content analysis. The results were used to derive initial requirements for a new AR-based teleconsultation system and to gain a better understanding of users’ needs. Results are discussed in the light of an early stage in the development process. According to the approach of human centred design the results serve as initial ndings which will be considered in the further development process.
