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} } @misc{AckermannBoehmWeinzierl2018, author = {Ackermann, David and B{\"o}hm, Christoph and Weinzierl, Stefan}, title = {A Database on Musicians' Movements During Musical Performances}, publisher = {TU Berlin}, doi = {10.14279/depositonce-7469}, year = {2018}, abstract = {The movements of 20 musicians playing 11 different musical instruments, including all standard orchestral instruments, were captured during solo performances by means of a motion capturing system under concert-like conditions.}, language = {en} } @misc{AckermannIlseGrigorievetal.2018, author = {Ackermann, David and Ilse, Michael and Grigoriev, Dmitry and Lepa, Steffen and Pelzer, S{\"o}nke and Vorl{\"a}nder, Michael and Weinzierl, Stefan}, title = {A Ground Truth on Room Acoustical Analysis and Perception (GRAP)}, publisher = {TU Berlin}, address = {Berlin}, doi = {10.14279/depositonce-7003.4}, year = {2018}, abstract = {A database of 35 virtual room models was created that can serve as a ground truth for the future development of room acoustical parameters beyond ISO 3382-1.

Others are artificial designs which were made to systematically cover a wide variety of room acoustical properties.

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{BoehmAckermannWeinzierl2018, author = {B{\"o}hm, Christoph and Ackermann, David and Weinzierl, Stefan}, title = {A Multi-channel Anechoic Orchestra Recording of Beethoven's Symphony No. 8 op. 93: Audio Recordings and Accompanying Data}, publisher = {TU Berlin}, address = {Berlin}, doi = {10.14279/depositonce-6729.2}, year = {2018}, abstract = {This data set contains an excerpt of the anechoic recording of the Symphony No. 8 in F Major, Op. 93 by Ludwig van Beethoven, performed by the "Orchester Wiener Akademie" conducted by Martin Haselb{\"o}ck.

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. This paper is of interest not only for research institutes of the metal-industry, but also for any areas of work, in which the enhancement with augmented reality is possible and a precise tracking is necessary.}, language = {en} }
