- WorkshopbeitragApplication 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, ThomasMedical 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.

- KonferenzbeitragOIDC-Agent: Managing OpenID Connect Tokens on the Command Line(SKILL 2018 - Studierendenkonferenz Informatik, 2018) Zachmann, GabrielOpenID Connect is widely used in Authentication and Authorization Infrastructures including the infrastructures of multiple EU projects like INDIGO -DataCloud, the Human Brain Project or the European Open Science Cloud. Due to their nature, OpenID Connect Access Tokens are currently not straightforward to use from the command line. They have a high character count and are short lived. Therefore, they de facto have to be copied from a source providing the access token, most likely a web service. Considering this insufficient usability from the command line, our goal was to overcome this by developing a tool to manage OpenID Connect tokens. We present the design of this tool named oidc-agent and possible usages. The design is oriented at the ssh-agent, providing the user a familiar way to handle OpenID Connect tokens. By splitting the whole service into multiple components we also ensure privilege separation. We implemented a daemon to manage OpenID Connect tokens (oidc-agent), a tool for generating agent account conĄgurations (oidc-gen) and a tool for loading and unloading these configurations from the agent (oidc-add). Additionally, we provide application programming interfaces for agent clients through C and UNIX domain sockets. We also provide an example agent client (oidc-token) that can be used to easily get an access token from oidc-agent using the command line. Therefore, users do not need to handle long, unhandy access tokens, but the application can obtain an access-token through oidc-agent when needed. All components can be freely used and are available on GitHub under the MIT license.
