Typical metrics like intersection-over-union (IoU), precisionrecallcurves or average precision (AP) quantify the performance over a whole database of images, neglecting spatial performance variations. But as the optics of camera systems are spatially variable over the field of view, the performance of ML-based algorithms is also a function of space, which we show in simulation: A realistic objective lens based on a Cooke-triplet that exhibits typical optical aberrations like astigmatism and chromatic aberration, all variable over field, is modeled. The model is then applied to a subset of the BDD100k dataset with spatially-varying kernels. We then quantify local changes in the performance of the pre-trained Mask R-CNN algorithm. Our examples demonstrate the spatial dependence of the performance of ML-based algorithms from the optical quality over field, highlighting the need to take the spatial dimension into account when training ML-based algorithms, especially when looking forward to autonomous driving applications.}, language = {en} } @article{WittpahlDeeganBlacketal.2021, author = {Wittpahl, Christian and Deegan, Brian and Black, Bob and Braun, Alexander}, title = {An analytic-numerical image flicker study to test novel flicker metrics}, series = {Electronic Imaging: Society for Imaging Science and Technology}, journal = {Electronic Imaging: Society for Imaging Science and Technology}, number = {17}, publisher = {Society for Imaging Science and Technology}, issn = {2470-1173}, doi = {10.2352/ISSN.2470-1173.2021.17.AVM-183}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-35671}, pages = {1 -- 8}, year = {2021}, language = {en} } @misc{HuldtgrenKatsimerouKuijstersetal.2015, author = {Huldtgren, Alina and Katsimerou, Christina and Kuijsters, Andre and Redi, Judith A. and Heynderickx, Ingrid E.

In addition, gerontologists criticized lately how older people's participation unfolds in technology design projects, e.g. that people are pushed into the role of users. Little is known about the motivations and needs of older adults regarding their participation in HCI research. To close this gap, we conducted an online survey (N=46) and semi-structured interviews (N=8) focusing on motivations, willingness and experiences regarding participation. Results show that people are generally willing to participate due to interest in the topic, learning new things and social bonding.

Although it is known that cytoskeletal coordination is vital for cell function, the mechanisms by which cross-linking proteins coordinate actin and microtubule activities remain poorly understood. In particular, it is unknown how the distinct mechanical properties of different actin architectures modulate the outcome of actin-microtubule interactions. To address this question, we engineered the protein TipAct, which links growing microtubule ends via end-binding proteins to actin filaments. We show that growing microtubules can be captured and guided by stiff actin bundles, leading to global actin-microtubule alignment. Conversely, growing microtubule ends can transport, stretch and bundle individual actin filaments, thereby globally defining actin filament organization. Our results provide a physical basis to understand actin-microtubule cross-talk, and reveal that a simple cross-linker can enable a mechanical feedback between actin and microtubule organization that is relevant to diverse biological contexts.}, language = {en} } @article{RuthHantschelLoepthienetal.2024, author = {Ruth, Nicolas and Hantschel, Florian and Loepthien, Tim and Randall, Will M. and Steffens, Jochen}, title = {The relation between technology acceptance and music listening: An experience sampling study}, series = {Jahrbuch Musikpsychologie}, volume = {32}, journal = {Jahrbuch Musikpsychologie}, publisher = {Leibniz Institute for Psychology (ZPID)}, issn = {2569-5665}, doi = {10.5964/jbdgm.181}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-44662}, pages = {1 -- 10}, year = {2024}, abstract = {In the intersection of technology and music listening, understanding user experiences is paramount. This research employed the Experience Sampling Method via the smartphone app MuPsych to continuously capture real-time data on individuals' music listening behaviors and related emotional responses.

Results indicate that Spotify Premium was the most frequently used music application, with personal playlists being the preferred listening format. To unravel the intricacies of these responses and their determinants, linear mixed-effects model analysis was utilized. Among the critical findings, the Perceived Usefulness and Perceived Ease of Use, two of the central constructs of the Technology Acceptance Model, emerged as significant predictors for the valence and enjoyment of the music experienced by users during the onset of music listening sessions. This highlights the imperative role of user-friendly interfaces in enhancing positive emotional states even before fully engaging with the music, underscoring the need for designers and developers of music-related apps to prioritise usability and useful functions.}, language = {en} } @article{PreciadoLopezHuberGrigorievetal.2014, author = {Preciado L{\´o}pez, Magdalena and Huber, Florian and Grigoriev, Ilya and Steinmetz, Michel O. and Akhmanova, Anna and Dogterom, Marileen and Koenderink, Gijsje H.}, title = {In vitro reconstitution of dynamic microtubules interacting with actin filament networks}, series = {Methods in Enzymology}, volume = {540}, journal = {Methods in Enzymology}, publisher = {Elsevier}, issn = {1557-7988}, doi = {10.1016/B978-0-12-397924-7.00017-0}, pages = {301 -- 320}, year = {2014}, language = {en} } @article{GeerkensSieberichsBraunetal.2024, author = {Geerkens, Simon and Sieberichs, Christian and Braun, Alexander and Waschulzik, Thomas}, title = {QI²: an interactive tool for data quality assurance}, series = {AI and Ethics}, volume = {4}, journal = {AI and Ethics}, publisher = {Springer Nature}, issn = {2730-5961}, doi = {10.1007/s43681-023-00390-6}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-42945}, pages = {141 -- 149}, year = {2024}, abstract = {The importance of high data quality is increasing with the growing impact and distribution of ML systems and big data.

{2023}, abstract = {Refractive power measurements serve as the primary quality standard in the automotive glazing industry. In the light of autonomous driving new optical metrics are becoming more and more popular for specifying optical quality requirements for the windshield. Nevertheless, the link between those quantities and the refractive power needs to be established in order to ensure a holistic requirement profile for the windshield. As a consequence, traceable high-resolution refractive power measurements are still required for the glass quality assessment. Standard measurement systems using Moir{\´e} patterns for refractive power monitoring in the automotive industry are highly resolution limited, wherefore they are insufficient for evaluating the camera window area. Consequently, there is a need for more sophisticated refractive power measurement systems that provide a higher spatial resolution. In addition, a calibration procedure has to be developed in order to guarantee for comparability of the measurement results. For increasing the resolution, a measurement setup based on an auto-correlation algorithm is tested in this paper. Furthermore, a calibration procedure is established by using a single reference lens with a nominal refractive power of 100 km-1. For the calibration of the entire measurement range of the system, the lens is tilted by an inclination angle orthogonal to the optical axis. The effective refractive power is then given by the Kerkhof model. By adopting the measurement and calibration procedure presented in this paper, glass suppliers in the automotive industry will be able to detect relevant manufacturing defects within the camera window area more accurately paving the way for a holistic quality assurance of the windshield for future advanced driver-assistance system (ADAS) functionalities. Concurrently, the traceability of the measurement results is ensured by establishing a calibration chain based on a single reference lens, which is traced back to international standards.}, language = {en} } @article{MuellerBraun2023, author = {M{\"u}ller, Patrick and Braun, Alexander}, title = {MTF as a performance indicator for AI algorithms?}, series = {Electronic Imaging: Society for Imaging Science and Technology}, volume = {35}, journal = {Electronic Imaging: Society for Imaging Science and Technology}, number = {16}, publisher = {Society for Imaging Science and Technology}, issn = {2470-1173}, doi = {10.2352/EI.2023.35.16.AVM-125}, pages = {1 -- 7}, year = {2023}, abstract = {Abstract The modulation-transfer function (MTF) is a fundamental optical metric to measure the optical quality of an imaging system. In the automotive industry it is used to qualify camera systems for ADAS/AD. Each modern ADAS/AD system includes evaluation algorithms for environment perception and decision making that are based on AI/ML methods and neural networks. The performance of these AI algorithms is measured by established metrics like Average Precision (AP) or precision-recall-curves. In this article we research the robustness of the link between the optical quality metric and the AI performance metric. A series of numerical experiments were performed with object detection and instance segmentation algorithms (cars, pedestrians) evaluated on image databases with varying optical quality. We demonstrate with these that for strong optical aberrations a distinct performance loss is apparent, but that for subtle optical quality differences - as might arise during production tolerances - this link does not exhibit a satisfactory correlation. This calls into question how reliable the current industry practice is where a produced camera is tested end-of-line (EOL) with the MTF, and fixed MTF thresholds are used to qualify the performance of the camera-under-test.}, language = {en} } @inproceedings{HuldtgrenMertlVormannetal.2016, author = {Huldtgren, Alina and Mertl, Fabian and Vormann, Anja and Geiger, Christian}, title = {Reminiscence of People with Dementia Mediated by a Tangible Multimedia Book}, series = {Proceedings of the International Conference on Information and Communication Technologies for Ageing Well and e-Health,, Rome, 21.04.2016 - 22.04.2016}, booktitle = {Proceedings of the International Conference on Information and Communication Technologies for Ageing Well and e-Health,, Rome, 21.04.2016 - 22.04.2016}, publisher = {SCITEPRESS - Science and Technology Publications}, isbn = {978-989-758-180-9}, doi = {10.5220/0005758801910201}, pages = {191 -- 201}, year = {2016}, language = {en} } @inproceedings{HuldtgrenVormannGeiger2015, author = {Huldtgren, Alina and Vormann, Anja and Geiger, Christian}, title = {Reminiscence Map - Insights to Design for People with Dementia from a Tangible Prototype}, series = {Proceedings of the 1st International Conference on Information and Communication Technologies for Ageing Well and e-Health, Lisbon, 20.05.2015 - 22.05.2015}, booktitle = {Proceedings of the 1st International Conference on Information and Communication Technologies for Ageing Well and e-Health, Lisbon, 20.05.2015 - 22.05.2015}, publisher = {SCITEPRESS - Science and Technology Publications}, isbn = {978-989-758-102-1}, doi = {10.5220/0005442702330242}, pages = {233 -- 242}, year = {2015}, language = {en} } @article{BergstroemElQasemMorville2021, author = {Bergstr{\"o}m, Aileen and El-Qasem, Kawthar and Morville, Anne-Le}, title = {JOS Special Issue: Occupational Science in Europe}, series = {Journal of Occupational Science}, volume = {28}, journal = {Journal of Occupational Science}, number = {1}, publisher = {Taylor \& Francis}, issn = {1442-7591}, doi = {10.1080/14427591.2021.1886644}, pages = {1 -- 5}, year = {2021}, language = {en} } @article{Gerhards2017, author = {Gerhards, Claudia}, title = {Product placement on YouTube: An explorative study on YouTube creators' experiences with advertisers}, series = {Convergence: The International Journal of Research into New Media Technologies}, volume = {25}, journal = {Convergence: The International Journal of Research into New Media Technologies}, number = {3}, publisher = {SAGE Publications}, issn = {1354-8565}, doi = {10.1177/1354856517736977}, pages = {516 -- 533}, year = {2017}, abstract = {During its process of diffusion, YouTube has become increasingly attractive for advertisers, not only in terms of classical commercials (like pre-roll ads) but also in terms of product placement opportunities.
