Animated virtual humans, avatars and agents alike, are the central entities in virtual embodied human-computer and human-human encounters in social XR. Here, a faithful reconstruction of facial expressions becomes paramount due to their prominent role in non-verbal behavior and social interaction. Current XR-platforms, like Unity 3D or the Unreal Engine, integrate recent smartphone technologies to animate faces of virtual humans by facial motion capturing. Using the same technology, this article presents an optimization-based approach to generate personalized blendshapes as animation targets for facial expressions. The proposed method combines a position-based optimization with a seamless partial deformation transfer, necessary for a faithful reconstruction. Our method is fully automated and considerably outperforms existing solutions based on example-based facial rigging or deformation transfer, and overall results in a much lower reconstruction error. It also neatly integrates with recent smartphone-based reconstruction pipelines for mesh generation and automated rigging, further paving the way to a widespread application of human-like and personalized avatars and agents in various use-cases.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121036800","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}

The main contribution of our study is that we assessed instructor’s capacity in one-to-many AR remote instruction giving both subjectively and objectively. We compared the remote instructor’s workload while interacting with a different number of local workers, assuming tasks at an industrial site. The results showed that the instructors perceived stronger workload and the communication quality became lower when interacting with multiple local workers. Based on the results, we discussed how to support the remote instructor in a one-to-many AR remote collaboration.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124406885","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}

The use of look-alike avatars could completely change how we interact virtually. This paper investigates which features of other people’s look-alike avatars influence our perceived realism. Four levels of avatar representations were assessed in this pilot study: a static avatar, a static avatar with lip sync corresponding to an audio recording, full face animation with audio and a full body animation. Results show that full-face and body animations are very important in increasing the perceived realism of avatars. More importantly, participants found the lip sync animation more unsettling (uncanny valley effect) than any of the other animations. The results have implications for the perception of other people’s look-alike avatars in collaborative virtual environments.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129904935","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}

Twelve participants completed the simulation and a survey. Preliminary results showed that 72.7% of participants bought food from the green grocer, 18.2% from the fast food store, and 9.1% from the supermarket. The mean presence score was 38.9 out of 49 and the mean usability score was 85.9 out of 100.

Recent developments in photogrammetry have facilitated the incorporation of real objects into virtual space. However, reproducing complex appearances, such as subsurface scattering and transparency, still requires a dedicated environment for measurement and possesses a trade-off between rendering quality and frame rate. Our NeARportation framework combines server–client bidirectional communication and neural rendering to resolve these trade-offs. Neural rendering on the server receives the client’s head posture and generates a novel-view image with realistic appearance reproduction that is streamed onto the client’s display. By applying our framework to a stereoscopic display, we confirm that it can display a high-fidelity appearance on full-HD stereo videos at 35-40 frames per second (fps) according to the user’s head motion.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"348 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123361998","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 study, we conducted an experiment to initially reveal how the size of a large object in a VR environment affects changes in participants’ (N = 38) anxiety level and heart rate. To holistically quantify the size of large objects in the VR visual field, we used the omnidirectional field of view occupancy (OFVO) criterion for the first time to represent the dimension of the object in the participant’s entire field of view. The results showed that the participants’ heartbeat and anxiety while viewing the large objects were positively and significantly correlated to OFVO. These study reveals that the increase of object size in VR environments is accompanied by a higher degree of user’s anxiety.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"378 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133176208","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}

Deep learning based 3D reconstruction approaches allow us to recover 3D shapes from 2D observations, among which single-view-based approaches can reduce the need for human intervention and specialised equipment in acquiring 3D sculptures for VR museums. However, there exist two challenges when attempting to use the well-researched human reconstruction methods: limited data availability and domain shift. Considering sculptures are usually related to humans, we propose our unsupervised 3D domain adaptation method for adapting a single-view 3D implicit reconstruction model from the source (real-world humans) to the target (sculptures) domain. We have compared the generated shapes with other methods and conducted ablation studies as well as a user study to demonstrate the effectiveness of our adaptation method. We also deploy our results in a VR application.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115064061","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}
