This paper presents BIMFlexi-VR, a collaborative framework which implements a real-time bidirectional link between a parametric modelling component created in Grasshopper for Rhinoceros that performs optimized structural calculations of an industrial building, and an immersive Virtual Reality environment in which the automatically calculated building is visualized. Users of BIMFlexi-VR are able to change parameters defining the outcome of the structural calculation directly inside the virtual environment and see the modified building design together with the associated fitness metrics in a matter of seconds. Providing an efficient and intuitive platform for early exploration of industrial building designs, BIMFlexi-VR enables collaborative decision making and facilitates the creation of more efficient and sustainable industrial constructions.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": false, "access":

Here, we introduce a Virtual Reality\n(VR) platform that overcomes these limitations by facilitating the thorough visual, and\ninteractive, exploration of large networks. Our platform allows maximal customization and\nextendibility, through the import of custom code for data analysis, integration of external\ndatabases, and design of arbitrary user interface elements, among other features. As a proof\nof concept, we show how our platform can be used to interactively explore genome-scale\nmolecular networks to identify genes associated with rare diseases and understand how they\nmight contribute to disease development. Our platform represents a general purpose, VRbased\ndata exploration platform for large and diverse data types by providing an interface\nthat facilitates the interaction between human intuition and

Data and information created by various processes (e.g., simulations) is getting larger, and more and more complex. We use interactive visualization and analysis techniques to facilitate exploration of complex parameter spaces (e.g., to analyze and compare parameters for automotive engineering, reconstruction algorithms, or geometry generators) or unstructured information collections (e.g., annotated digital documents or image collections). Our research focus lies on novel visual encodings and interaction techniques to explore a large amount of abstract data, often in combination with analytical reasoning.

A mismatch between virtual and real relative user positions might lead to harmful events such as physical user collisions. This paper examines three calibration methods that enable colocated Virtual Reality scenarios for SLAM-tracked head-mounted displays without the need for an external tracking system. Two of these methods—fixed-point calibration and marked-based calibration—have been described in previous research; the third method that uses hand tracking capabilities of head-mounted displays is novel. We evaluated the accuracy of these three methods in an experimental procedure with two colocated Oculus Quest devices. The results of the evaluation show that our novel hand tracking-based calibration method provides better accuracy and consistency while at the same time being easy to execute. The paper further discusses the potential of all evaluated calibration methods.

Experimental studies related to the control of human locomotion in REs during curved trajectories report a top-down reorientation strategy with the reorientation of the gaze anticipating the reorientation of head, the shoulders and finally the global body motion. This anticipation behavior provides a stable reference frame to the walker to control and reorient his/her body according to the future walking direction. To assess body anticipation during navigation in VEs, we conducted an experiment where participants, wearing a head-mounted display, performed a lemniscate trajectory in a virtual environment (VE) using five different navigation techniques, including walking, virtual steering (head, hand or torso steering) and passive navigation. For the purpose of this experiment, we designed a new control law based on the power-law relation between speed and curvature during human walking. Taken together our results showed a similar ordered top-down sequence of reorientation of the gaze, head and shoulders during curved trajectories between walking in REs and in VEs (for all the evaluated techniques). However, the anticipation mechanism was significantly higher for the walking condition compared to the others. The results presented in this paper pave the way to the better understanding of the underlying mechanisms of human navigation in VEs and to the design of navigation techniques more adapted to humans.", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ { "id": 1715, "drupal_id": null, "orcid_id": null, "website": null, "firstname": "Hugo", "lastname": "Brument", "searchname": "Hugo Brument", "is_teacher": false, "name": "Hugo Brument", "publications": [ "brument_2019_br19" ], "publications_first": [ "brument_2019_br19" ], "project_leader": [], "publication_field": [ { "publ_id": "brument_2019_br19", "field_id": "lecturer", "ordernum": 0 } ], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=1715", "__class": "Author" }, { "id": 1945, "drupal_id": 1521, "orcid_id": null, "website": "https://www.cg.tuwien.ac.at/staff/IanaPodkosova", "firstname": "Iana", "lastname": "Podkosova", "searchname": "Iana Podkosova", "is_teacher": false, "name": "Iana Podkosova", "publications": [ "brument_2019_br19", "pirch_2021_VRN", "Podkosova_2021", "podkosova_2022_bimflexi-vr", "podkosova-2019-MVR", "reimer-2021-CVR" ], "publications_first": [ "Podkosova_2021", "podkosova_2022_bimflexi-vr", "podkosova-2019-MVR" ], "project_leader": [], "publication_field": [ { "publ_id": "perl_oskar_2021_DVR", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Podkosova_2021", "field_id": "lecturer", "ordernum": 0 } ], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=1945", "__class": "Author" }, { "id": 378, "drupal_id": 366, "orcid_id": "0000-0002-0322-9869", "website": "https://www.cg.tuwien.ac.at/staff/HannesKaufmann", "firstname": "Hannes", "lastname": "Kaufmann", "searchname": "Hannes Kaufmann", "is_teacher": false, "name": "Hannes Kaufmann", "publications": [ "adolf-2019-jug", "brument_2019_br19", "Goellner_2019-ABC", "huber-2025-esl", "kan-2019-dli", "Kauf-2000-Con", "medeiros-2025-iaa", "Mirzaei_Mohammad-2021", "Mirzaei_Mohammad-2021-HeadUp", "Mirzaei_Mohammadreza_2020-EVR", "Mirzaei_Mohhamad-2021", "mortezapoor-2022-photogrammabot", "Mossel_Annette_2020-TVR", "pirch_2021_VRN", "podkosova_2022_bimflexi-vr", "reimer-2020-CBG", "reimer-2021-CVR", "Reisinger-2021-JOBE", "Schoenauer_2020_POI", "Sebernegg2020", "Vasylevska_Khrystyna-2019-TEFVR", "Vasylevska2020VRB", "Vonach021", "wimmer-2022-acd" ], "publications_first": [ "Kauf-2000-Con" ], "project_leader": [ "AR-AQ-Bau", "BimFlexi", "d4317", "d4322", "d4330", "d4338", "d4340", "d4400", "d4673", "d4710", "d4713", "EvaluARte", "VHH" ], "publication_field": [ { "publ_id": "adolf-2019-jug", "field_id": "lecturer", "ordernum": 0 }, { "publ_id": "Bayer_Alexander_2021_FTiVR", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "kan-2019-dli", "field_id": "lecturer", "ordernum": 0 }, { "publ_id": "koessler-2021-i3d", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Kovacs_2020", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Mirzaei_Mohammadreza_2020-EVR", "field_id": "lecturer", "ordernum": 0 }, { "publ_id": "podkosova-2019-MVR", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Prossenitsch_2019-1", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "schlager-2021-ddo", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "schuller_reichl-2019-avt", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "schwaerzler_2018_phd", "field_id": "reviewer_2", "ordernum": 0 }, { "publ_id": "Sprung_2021", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "unterguggenberger-2016-realmar", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "wang-sukalia-2022-mom", "field_id": "supervisor", "ordernum": 0 } ], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=378", "__class": "Author" }, { "id": 1740, "drupal_id": null, "orcid_id": null, "website": null, "firstname": "Anne-Helene", "lastname": "Olivier", "searchname": "Anne-Helene Olivier", "is_teacher": false, "name": "Anne-Helene Olivier", "publications": [ "brument_2019_br19", "Podkosova_2021" ], "publications_first": [], "project_leader": [], "publication_field": [], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=1740", "__class": "Author" }, { "id": 1741, "drupal_id": null, "orcid_id": null, "website": null, "firstname": "Ferran", "lastname": "Argelaguet", "searchname": "Ferran Argelaguet", "is_teacher": false, "name": "Ferran Argelaguet", "publications": [ "brument_2019_br19" ], "publications_first": [], "project_leader": [], "publication_field": [], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=1741", "__class": "Author" } ], "booktitle": "Proceedings of IEEE VR 2019 -

We consider a setup to be multi-user if at least one of these\n two spaces is shared. The dissertation starts with the classification of combinations of\n physical and virtual colocation. Four such combinations are defined: colocated shared VR,\n colocated non-shared VR, distributed shared VR and shared VR with mixed colocation.\n The characteristics of each of these four setups are discussed and the resulting problems\n and research questions outlined.\n The dissertation continues with the description of ImmersiveDeck - a large-scale multi-user\n VR platform that enables navigation by walking and natural interaction. Then, four\n experiments on multi-user walkable VR developed with the use of ImmersiveDeck are\n described.\n The first two experiments are set in colocated non-shared VR where walking users share\n a tracking space while being immersed into separate virtual worlds. We investigate users´\n mutual awareness in this setup and explore methods of preventing mutual collisions\n between walking users. The following two experiments study shared VR scenarios in\n situations of varied physical colocation. We investigate the effects that different modes\n of physical colocation have on locomotion, collision avoidance and proxemics patterns\n exhibited by walking users. The sense of copresence and social presence within the virtual\n world reported by users is investigated as well.\n The experiments in the colocated non-shared VR setup show that HMD-based VR can\n produce immersion so strong that users do not notice others being present in their\n immediate proximity, thus making collision prevention the task of utmost importance. In\n our proposed method of displaying notification avatars to prevent potential imminent\n collisions between colocated users, the suitability of a particular type of notification avatar\n was found to be dependent on the type of scenario experienced by users. The general\n result of the experiments in shared VR is that physical colocation affects locomotor and\n proxemics behavior of users as well as their subjective experience in terms of copresence.\n In particular, users are more cautious about possible collisions and more careful in their\n collision avoidance behavior in the colocated setup compared to the real environment. In\n the distributed setup, conventional collision avoidance is often abandoned.\n vi", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ { "id": 1945, "drupal_id": 1521, "orcid_id": null, "website": "https://www.cg.tuwien.ac.at/staff/IanaPodkosova", "firstname": "Iana", "lastname": "Podkosova", "searchname": "Iana Podkosova", "is_teacher": false, "name": "Iana Podkosova", "publications": [ "brument_2019_br19", "pirch_2021_VRN", "Podkosova_2021", "podkosova_2022_bimflexi-vr", "podkosova-2019-MVR", "reimer-2021-CVR" ], "publications_first": [ "Podkosova_2021", "podkosova_2022_bimflexi-vr", "podkosova-2019-MVR" ], "project_leader": [], "publication_field": [ { "publ_id": "perl_oskar_2021_DVR", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Podkosova_2021", "field_id": "lecturer", "ordernum": 0 } ], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=1945", "__class": "Author" } ], "duration": "7", "open_access": "no", "rigorosum": "2019-02-08", "supervisor": [ { "id": 378, "drupal_id": 366, "orcid_id": "0000-0002-0322-9869", "website": "https://www.cg.tuwien.ac.at/staff/HannesKaufmann", "firstname": "Hannes", "lastname": "Kaufmann", "searchname": "Hannes Kaufmann", "is_teacher": false, "name": "Hannes Kaufmann", "publications": [ "adolf-2019-jug", "brument_2019_br19", "Goellner_2019-ABC", "huber-2025-esl", "kan-2019-dli", "Kauf-2000-Con", "medeiros-2025-iaa", "Mirzaei_Mohammad-2021", "Mirzaei_Mohammad-2021-HeadUp", "Mirzaei_Mohammadreza_2020-EVR", "Mirzaei_Mohhamad-2021", "mortezapoor-2022-photogrammabot", "Mossel_Annette_2020-TVR", "pirch_2021_VRN", "podkosova_2022_bimflexi-vr", "reimer-2020-CBG", "reimer-2021-CVR", "Reisinger-2021-JOBE", "Schoenauer_2020_POI", "Sebernegg2020", "Vasylevska_Khrystyna-2019-TEFVR", "Vasylevska2020VRB", "Vonach021", "wimmer-2022-acd" ], "publications_first": [ "Kauf-2000-Con" ], "project_leader": [ "AR-AQ-Bau", "BimFlexi", "d4317", "d4322", "d4330", "d4338", "d4340", "d4400", "d4673", "d4710", "d4713", "EvaluARte", "VHH" ], "publication_field": [ { "publ_id": "adolf-2019-jug", "field_id": "lecturer", "ordernum": 0 }, { "publ_id": "Bayer_Alexander_2021_FTiVR", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "kan-2019-dli", "field_id": "lecturer", "ordernum": 0 }, { "publ_id": "koessler-2021-i3d", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Kovacs_2020", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Mirzaei_Mohammadreza_2020-EVR", "field_id": "lecturer", "ordernum": 0 }, { "publ_id": "podkosova-2019-MVR", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "Prossenitsch_2019-1", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "schlager-2021-ddo", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "schuller_reichl-2019-avt", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "schwaerzler_2018_phd", "field_id": "reviewer_2", "ordernum": 0 }, { "publ_id": "Sprung_2021", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "unterguggenberger-2016-realmar", "field_id": "supervisor", "ordernum": 0 }, { "publ_id": "wang-sukalia-2022-mom", "field_id": "supervisor", "ordernum": 0 } ], "url": "https://www.cg.tuwien.ac.at/research/publications/show.php?class=Author&id=378", "__class": "Author" } ], "research_areas": [], "keywords": [ "virtual reality", "multi-user VR" ], "weblinks": [ { "href": "https://publik.tuwien.ac.at/files/publik_278458.pdf", "caption": "Paper link", "description": null, "main_file": 0 } ], "files": [], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/2019/podkosova-2019-MVR/", "__class": "Publication" } ]
