    Application Scenarios for 3D-Printed Organ Models for Collaboration in VR & AR
    (Mensch und Computer 2019 - Workshopband, 2019) Muender, Thomas; Reinschluessel, Anke; Zargham, Nima; Döring, Tanja; Wenig, Dirk; Malaka, Rainer; Fischer, Roland; Zachmann, Gabriel; Schumann, Christian; Kraft, Valentin; Schenk, Andrea; Uslar, Verena; Weyhe, Dirk; Nopper, Hans; Lück, Thomas
    Medical software for computer-assisted surgery often solely supports one phase of the surgical process, e.g., surgery planning. This paper describes a concept for a system, which can be seamlessly used in the preoperative planning phase, in the intraoperative phase for viewing the planning data, as well as for training and education. A combination of virtual and augmented reality with a multi-user functionality will support the three phases. 3D-printed organ models will be used as interaction devices for more intuitive interaction with the visual data and for educating future surgeons. We present the three application scenarios for this concept in detail and discuss the research opportunities.

    Demonstrating Dothraki: Tracking Tangibles Atop Tabletops Through De-Bruijn Tori
    (Mensch und Computer 2021 - Tagungsband, 2021) Schüsselbauer, Dennis; Schmid, Andreas; Wimmer, Raphael
    We demonstrate usage examples and technical properties of Dothraki, an inside-out tracking technique for tangibles on flat surfaces. An optical mouse sensor embedded in the tangible captures a small (36×36 pixel / 1×1 mm), unique section of a black-and-white De-Bruijn dot pattern printed on the surface. Our system efficiently searches the pattern space in order to determine the precise location of the tangible with sub-millimeter accuracy. Our proof-of-concept implementation offers a recognition rate of up to 95%, robust error detection, an update rate of 14 Hz, and a low-latency relative tracking mode. The MuC demonstration encompasses four separate demos that showcase typical application scenarios and features: a magic lens, two tangibles that know each others relative position, a simple geometry application that measures distances and angles, and tangibles that know on which of multiple surfaces they have been placed.

    Overview of Collaborative Virtual Environments using Augmented Reality
    (Mensch und Computer 2019 - Workshopband, 2019) Feld, Nico; Weyers, Benjamin
    Using a collaborative virtual environment (CVE) can reduce the barriers of remote communication, which makes CVEs being increasingly used to support collaborative work between spatially dispersed collaborators. Augmented reality (AR) builds a bridge between working in real and virtual environment, which makes AR a candidate technology to implement CVEs. To structure this research field and to identify possible lacks of research, this paper proposes a design space of CVEs using AR. Therefore, we mapped described solutions in research literature onto the CVE's definition, which considers user-roles as well as benefits gained by AR. Additionally, we concentrate on the consistency of using specific keywords in the field. By means of the gained design space, we identified certain gaps in research and present potential next research topics in the field.
