It is typically caused by exposure to mismatches between real and virtual motion, which happens in most VR Locomotion techniques. Hence, VR Locomotion and VR Sickness are intimately related, but this relationship is not reflected in the state of VR Sickness assessment. In this work we highlight the importance of understanding and quantifying VR Sickness in VR locomotion research. We discuss the most important factors and measures of VR to develop VR Sickness as a meaningful metric for VR Locomotion.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116506136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When users explore virtual environments by walking they rely on stable visible landmarks to plan and execute their next movement. In my research I am developing novel methods to predict locomotion paths of human subjects for the immediate future, i.e. the next few seconds. I aim to connect different types of behavioral data (eye, hand, feet and head tracking) and test their reliability and validity for predicting walking behavior in virtual reality. Such a prediction will be very valuable for natural interaction, for example in redirected walking schemes.My approach begins with an evaluation of the quality of data gathered with current tracking methods. Informative experimental conditions need to be developed to find meaningful patterns in natural walking. Next, raw tracked data of different modalities need to be connected with each other and aggregated in a useful way. Thereafter, possible valid predictors need to be developed and compared to already functioning predicting algorithms (e.g. [2],[6],[12]). As a final goal, all valid predictors shall be used to create a prediction algorithm returning the most likely future path when exploring virtual environments.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115039853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because teleportation requires little physical effort and lets users traverse large distances instantly, a risk is that over time users might only use teleportation and abandon walking input. This paper provides insight into this risk by presenting results from a study that analyzes tracking space usage of three popular commercially available VR games that rely on teleportation. Our study confirms that positional tracking usage is limited by the use of teleportation.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123650368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a network, 2D3D-GAN-Net, to learn the local invariant cross-domain feature descriptors of 2D image patches and 3D point cloud volumes. Then, the learned local invariant cross-domain feature descriptors are used for matching 2D images and 3D point clouds. The Generative Adversarial Networks (GAN) is embedded into the 2D3D-GANNet, which is used to distinguish the source of the learned feature descriptors, facilitating the extraction of invariant local cross-domain feature descriptors. Experiments show that the local cross-domain feature descriptors learned by 2D3D-GAN-Net are robust, and can be used for cross-dimensional retrieval on the 2D image patches and 3D point cloud volumes dataset. In addition, the learned 3D feature descriptors are used to register the point cloud for demonstrating the robustness of learned local cross-domain feature descriptors.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"412 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126588254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its use has also dramatically increased during the current COVID-19 pandemic with social distancing and lockdown requirements. But online education has thus far been primarily limited to teaching of knowledge and cognitive skills. There is yet almost no use of online education for teaching of physical clinical skills.In this paper, we present a shared haptic virtual environment for dental surgical skill training. The system provides the teacher and student with a shared environment containing a virtual dental station with patient, a dental drill controlled by a haptic device, and a drillable tooth. It also provides automated scoring of procedure outcomes. We discuss a number of optimizations used in order to provide the high-fidelity simulation and real-time performance needed for training of high-precision clinical skills. Since tactile, in particular kinaesthetic, sense is essential in carrying out many dental procedures, an important question is how to best teach this in a virtual environment. In order to support exploring this, our system includes three modes for transmitting haptic sensations from the user performing the procedure to the user observing.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127725300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this poster paper, we explore the use of a smartphone as an input device to support text selection in AR-HMD because of its availability, familiarity, and social acceptability. As an initial attempt, we propose four eyes-free, uni-manual text selection techniques for AR-HMD, all using a smartphone - continuous touch, discrete touch, spatial movement, and raycasting.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121499662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
