The spacecraft design process relies on expertise in many domains, such as thermal and structural engineering. The various subsystems of a spacecraft are highly interdependent and have differing requirements and constraints. In this context, interactive visualizations play an important role in making expert knowledge accessible. Recent immersive display technologies offer new ways of presenting and interacting with computer-generated content. Possibilities and challenges for spacecraft configuration employing these technologies are explored and discussed. A user interface design for an application using the Microsoft HoloLens is proposed. To this end, techniques for selecting a spacecraft component and manipulating its position and orientation in 3D space are developed and evaluated. Thus, advantages and limitations of this approach to spacecraft configuration are revealed and discussed.}, language = {en} } @inproceedings{VermeegenHerder2018, author = {Vermeegen, Kai and Herder, Jens}, title = {A Lighthouse-based Camera Tracking System for Professional Virtual Studios}, series = {Workshop Proceedings / Tagungsband: Virtuelle und Erweiterte Realit{\"a}t - 15.

Ground truth tracking systems require markers to create high quality motion data. But in many applications it is desired to work without markers. In recent years affordable hardware for markerless tracking systems was made available at a consumer level. Efficient depth camera systems based on Time-of-Flight sensors and structured light systems have made it possible to record motion data in real time. However, the gap between the quality of marker-based and markerless systems is high. The error sources of a markerless motion tracking pipeline are discussed and a model-based filter is proposed, which adapts depending on spatial location. The proposed method is then proven to be more robust and accurate than the unfiltered data stream and can be used to visually enhance the presence of an actor within a virtual environment in live broadcast productions.}, language = {en} } @misc{Marmann2018, author = {Marmann, Michael}, title = {Agile Lernsettings zur Entwicklung der digital literacy - Perspektiven f{\"u}r die Hochschullehre}, series = {Ringvorlesung Medien / Zuk{\"u}nfte an der TU Braunschweig}, journal = {Ringvorlesung Medien / Zuk{\"u}nfte an der TU Braunschweig}, publisher = {Technische Universit{\"a}t Brauschweig}, address = {Braunschweig}, organization = {Technische Universit{\"a}t Brauschweig}, year = {2018}, abstract = {Die Buzzwords Agilit{\"a}t und Digitalisierung sind in aller Munde.

The prototype is created with hard- and software, that is usually employed in the gaming industry, and delivers positions for creating ultra- sonic material scans (C-scans). Using a stereo camera in combination with an hmd enables realtime visualisation of the probes path, as well as the setting of virtual markers on the specimen. As a part of the implementation the downhill simplex optimization algorithm is implemented to fit the specimen to a cloud of recorded surface points. The accuracy is statistically tested and evaluated with the result, that the tracking system is accurate up to ca. 1-2 millimeters in well set-up conditions.
