  @article{9709159, abstract = {Our built world is one of the most important factors for a livable future, accounting for massive impact on resource and energy use, as well as climate change, but also the social and economic aspects that come with population growth. The architecture, engineering, and construction industry is facing the challenge that it needs to substantially increase its productivity, let alone the quality of buildings of the future. In this article, we discuss these challenges in more detail, focusing on how digitization can facilitate this transformation of the industry, and link them to opportunities for visualization and augmented reality research. We illustrate solution strategies for advanced building systems based on wood and fiber.}, author = {Abdelaal, Moataz and Amtsberg, Felix and Becher, Michael and Estrada, Rebeca Duque and Kannenberg, Fabian and Calepso, Aimée Sousa and Wagner, Hans Jakob and Reina, Guido and Sedlmair, Michael and Menges, Achim and Weiskopf, Daniel}, doi = {10.1109/MCG.2022.3149837}, issn = {1558-1756}, journal = {IEEE Computer Graphics and Applications}, month = {March}, number = 2, pages = {10-20}, title = {Visualization for Architecture, Engineering, and Construction: Shaping the Future of Our Built World}, volume = 42, year = 2022 }

  @article{9732172, abstract = {Modern machines continuously log status reports over long periods of time, which are valuable data to optimize working routines. Data visualization is a commonly used tool to gain insights into these data, mostly in retrospective, e.g. to determine causal dependencies between faults of different machines. We present an approach to bring such visual analyses to the shop floor to support reacting to faults in real time. This approach combines combines spatio-temporal analyses of time series using a handheld touch device with augmented reality for live monitoring. Important information augments machines directly in their real-world context and detailed logs of current and historical events are displayed on the handheld device. In collaboration with an industry partner, we designed and tested our approach on a live production line to obtain feedback from operators. We compare our approach for monitoring and analysis with existing solutions that are currently deployed.}, author = {Becher, Michael and Herr, Dominik and Müller, Christoph and Kurzhals, Kuno and Reina, Guido and Wagner, Lena and Ertl, Thomas and Weiskopf, Daniel}, doi = {10.1109/MCG.2022.3157961}, issn = {1558-1756}, journal = {IEEE Computer Graphics and Applications}, pages = {1-1}, title = {Situated Visual Analysis and Live Monitoring for Manufacturing}, year = 2022 }

  @inproceedings{9623235, abstract = {Both visual detail and a low-latency transfer of image data are required for collaborative exploration of scientific data sets across large high-resolution displays. In this work, we present an approach that reduces the resolution before the encoding and uses temporal upscaling to reconstruct the full resolution image, reducing the overall latency and the required bandwidth without significantly impacting the details perceived by observers. Our approach takes advantage of the fact that humans do not perceive the full details of moving objects by providing a perfect reconstruction for static parts of the image, while non-static parts are reconstructed with a lower quality. This strategy enables a substantial reduction of the encoding latency and the required bandwidth with barely noticeable changes in visual quality, which is crucial for collaborative analysis across display walls at different locations. Additionally, our approach can be combined with other techniques aiming to reduce the required bandwidth while keeping the quality as high as possible, such as foveated encoding. We demonstrate the reduced overall latency, the required bandwidth, as well as the high image quality using different visualisations.}, author = {Frieß, Florian and Becher, Michael and Reina, Guido and Ertl, Thomas}, booktitle = {2021 IEEE 11th Symposium on Large Data Analysis and Visualization (LDAV)}, doi = {10.1109/LDAV53230.2021.00013}, pages = {53-62}, title = {Amortised Encoding for Large High-Resolution Displays}, url = {https://ieeexplore.ieee.org/document/9623235}, year = 2021 }

  @article{9126163, abstract = {Simulations of cosmic evolution are a means to explain the formation of the universe as we see it today. The resulting data of such simulations comprise numerous physical quantities, which turns their analysis into a complex task. Here, we analyze such high-dimensional and time-varying particle data using various visualization techniques from the fields of particle visualization, flow visualization, volume visualization, and information visualization. Our approach employs specialized filters to extract and highlight the development of so-called active galactic nuclei and filament structures formed by the particles. Additionally, we calculate X-ray emission of the evolving structures in a pre-processing step to complement visual analysis. Our approach is integrated into a single visual analytics framework to allow for analysis of star formation at interactive frame rates.

  @inproceedings{oney_evaluation_2020, abstract = {Gaze tracking in 3D has the potential to improve interaction with objects and visualizations in augmented reality. However, previous research showed that subjective perception of distance varies between real and virtual surroundings. We wanted to determine whether objectively measured 3D gaze depth through eye tracking also exhibits differences between entirely real and augmented environments. To this end, we conducted an experiment (N = 25) in which we used Microsoft HoloLens with a binocular eye tracking add-on from Pupil Labs. Participants performed a task that required them to look at stationary real and virtual objects while wearing a HoloLens device. We were not able to find significant differences in the gaze depth measured by eye tracking. Finally, we discuss our findings and their implications for gaze interaction in immersive analytics, and the quality of the collected gaze data.}, author = {Öney, Seyda and Rodrigues, Nils and Becher, Michael and Reina, Guido and Ertl, Thomas and Sedlmair, Michael and Weiskopf, Daniel}, booktitle = {Proceedings of the Symposium on Eye Tracking Research & Applications-Short Paper (ETRA-SP)}, doi = {10.1145/3379156.3391835}, pages = {49:1-49:5}, publisher = {ACM}, title = {Evaluation of Gaze Depth Estimation from Eye Tracking in Augmented Reality}, url = {https://doi.org/10.1145/3379156.3391835}, year = 2020 }

A straightforward algorithm has running time O(n2 log n) which we improve to expected O(Δdn(log n + Δd)) where Δ = rmax/rmin is the ratio between largest and smallest radius amongst the balls. For a natural application of this problem, namely drawing labels on the globe, we have Δ = O(1). An efficient implementation based on a spherical Delaunay triangulation allows to compute the elimination order for millions of labels on commodity Desktop hardware.
