  1. ; ; ; ; ; ; ; ( , 2022 8th International Conference of the Immersive Learning Research Network (iLRN))
    We present our work in progress, a real-time mixed reality communication system for remote assistance in medical emergency situations. 3D cameras capture the emergency situation and send volumetric data to a remote expert. The remote expert sees the volumetric scene through mixed reality glasses and guides an operator to the patient. The local operator receives audio and visual guidance augmented onto the mixed reality headset. We compare the mixed reality system against traditional video communication in a user study on a CPR emergency simulation. We evaluate task performance, cognitive load, and user interaction. The results will help to better understand the benefits of using augmented and volumetric information in medical emergency procedures.

  2. ; ; ; ; ; ; ; ( , 2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW))
    We present a volumetric communication system that is designed for remote assistance of procedural tasks. The system allows a remote expert to visually guide a local operator. The two parties share a view that is spatially identical, but for the local operator it is of the object on which they operate, while for the remote expert, the object is presented as a mixed reality “hologram”. Guidance is provided by voice, gestures, and annotations performed directly on the object of interest or its hologram. At each end of the communication, spatial is visualized using mixed-reality glasses.
