In this work we investigate the feasibility of recognising visual memory recall. We use a recognition methodology that combines minimum redundancy maximum relevance feature selection (mRMR) with a support vector machine (SVM) classifier. We validate the methodology in a dual user study with a total of fourteen participants looking at familiar and unfamiliar pictures from four picture categories: abstract, landscapes, faces, and buildings. Using person-independent training, we are able to discriminate between familiar and unfamiliar abstract pictures with a top recognition rate of 84.3% (89.3% recall, 21.0% false positive rate) over all participants.

The study participants have no prior experience as helicopter pilots. The flight simulation uses a dynamic model of a coaxial ultralight helicopter horizontal motion that includes a stability augmentation system. A virtual reality headset is used to give the participants a realistic sense of perspective. The benchmark task includes decelerating into hover and hovering above a target for a given time. Three cueing configurations are compared. One includes visual cues on the ground that mark the hover target position. The two others add either a heads down display or a heads up display inside the cockpit, which visualize the relative target position and a prediction of the helicopter motion. With the proposed displays available inside the cockpit, participants tend to reach the target faster and more consistently. Hover performance is not improved by an additional display as the pilots mostly rely on visual cues on the ground during hover. In summary, both log data and pilot feedback suggest that the proposed displays are primarily beneficial in flight phases where the helicopter moves.", "doi" : "10.4050/f-0079-2023-18029", "bibtexKey": "Rothaupt_2023" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/20dfb045213232a2162921e36d01a9aa6/jmueller", "tags" : [ "adaptive","based","ceramics,","control","controllable","crystal","devices,","direct","electrochromic","facade","films,","glass","glazed","glazing","glazing,","heat","intelligent","liquid","materials,","mechanism,","optical","optimisation,","optimization,","performance","properties","protection,","self-adjusting","smart","sobek","solar","sunlight","sunlight,","survey,","system","system,","systems,","thermochromic","transfer,","units,","visual","windows," ], "intraHash" : "0dfb045213232a2162921e36d01a9aa6", "interHash" : "01f845c3c121cf815ea4a02f5fee1662", "label" : "Potential of origami-based shell elements as next-generation envelope components", "user" : "jmueller", "description" : "", "date" : "2023-11-27 15:10:57", "changeDate" : "2023-11-27 15:10:57", "count" : 10, "pub-type": "inproceedings", "booktitle": "2017 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), July 3-7, 2017, Munich", "year": "2017", "url": "", "author": [ "Yves Klett","Peter Middendorf","Werner Sobek","Walter Haase","Michael Heidingsfeld" ], "authors": [ {"first" : "Yves", "last" : "Klett"}, {"first" : "Peter", "last" : "Middendorf"}, {"first" : "Werner", "last" : "Sobek"}, {"first" : "Walter", "last" : "Haase"}, {"first" : "Michael", "last" : "Heidingsfeld"} ], "pages": "916--920","abstract": "Building envelopes manage several crucial functions,\nincluding structural, thermal, hygric and aesthetic functions.\nClassic fac¸ade concepts usually work with static elements like glass, metal or composite panels that primarily provide protection against the elements, and an additional layer of active systems that manage dynamic tasks like light protection or thermal regulation.

Three hundred images with 0.67- or 5-mm section thickness were compressed to one of five compression ratios ranging from reversible compression to 15:1. The fidelity of each compressed image was measured by five radiologists' visual analyses (distinguishable or indistinguishable from the original) and the three metrics. The Spearman rank correlation coefficients of the PSNR, HDR-VDP, and MS-SSIM values with the number of readers responding as indistinguishable were 0.86, 0.94, and 0.86, respectively.
