Even slight variations in walking conditions like height or ground conditions can significantly impact walking performance. Virtual reality is used as a helpful tool to simulate such challenging situations. However, there is no agreement on design strategies for balance training in virtual reality under stressful environmental conditions such as height exposure. We investigate how two different training strategies, imitation learning, and gamified learning, can help dynamic balance control performance across different stress conditions. Moreover, we evaluate the stress response as indexed by peripheral physiological measures of stress, perceived workload, and user experience. Both approaches were tested against a baseline of no instructions and against each other. Thereby, we show that a learning-by-imitation approach immediately helps dynamic balance control, decreases stress, improves attention focus, and diminishes perceived workload. A gamified approach can lead to users being overwhelmed by the additional task. Finally, we discuss how our approaches could be adapted for balance training and applied to injury rehabilitation and prevention.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"20 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":"123740831","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}

A VR-based system has been developed that receives and visualizes the processed data from real-time RGB-D camera feeds. A real-world robot model has also been developed to provide realistic reactions and control feedback. The targets and the robot model are reconstructed in a VR environment and presented to users in different modalities. The modalities and available information are varied between experimental settings, and the associated task performance is recorded and analyzed. The results accumulated from 192 experiments completed by 8 participants showed that point cloud data is sufficient for completing the task. Additional information, either image stream or preliminary processes presented as annotations, was found to not have a significant impact on the completion time. However, the combination of image stream and colored point cloud data visualization modalities was found to greatly enhance a user’s performance accuracy, with the number of target centers missed being reduced by 40%.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"1 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":"128981587","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}

While progress has been made to provide custom electrotactile feedback for specific interaction tasks, it remains unclear which modulations and rendering algorithms are preferred in rich interaction scenarios. In this paper, we propose a unified tactile rendering architecture and explore the most promising modulations to render finger interactions in VR. Based on a literature review, we designed six electrotactile stimulation patterns/effects (EFXs) striving to render different tactile sensations. In a user study (N=18), we assessed the six EFXs in three diverse finger interactions: 1) tapping on a virtual object; 2) pressing down a virtual button; 3) sliding along a virtual surface. Results showed that the preference for certain EFXs depends on the task at hand. No significant preference was detected for tapping (short and quick contact); EFXs that render dynamic intensities or dynamic spatio-temporal patterns were preferred for pressing (continuous dynamic force); EFXs that render moving sensations were preferred for sliding (surface exploration). The results showed the importance of the coherence between the modulation an the interaction being performed and the study proved the versatility of electrotactile feedback and its efficiency in rendering different haptic information and sensations.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"2 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114121328","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}

These movements range from simple single-limb to complex multi-limb movements. While VR supports many perspectives – e.g., first person and third person – it remains unclear how accurate these perspectives communicate different movements. In a user study (N=18), we investigated the influence of perspective, feedback, and movement properties on the accuracy of movement guidance. Participants had on average an angle error of 6.2° for single arm movements, 7.4° for synchronous two arm movements, and 10.3° for synchronous two arm and leg movements. Furthermore, the results show that the two variants of third-person perspectives outperform a first-person perspective for movement guidance (19.9% and 24.3% reduction in angle errors). Qualitative feedback confirms the quantitative data and shows users have a clear preference for third-person perspectives. Through our findings we provide guidance for designers and developers of future VR movement guidance systems.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"32 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":"121936293","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}

Using the digital twin of the target environment, “magical” VR interaction techniques can be applied, as visualized and overlaid through the small window, while still maintaining the spatial association to the augmented real world. First we consider the use of amplified movement within the corresponding VR twinned space to help the user search, plan, navigate and explore efficiently by providing an effectively larger view and thereby better spatial understanding of the same AR space with less amount of physical movements. Secondly, we also apply the amplified movement and in addition, the stretchable arm to interact with relatively large objects (or largely spaced objects) which cannot be seen in their entirety at a time with the small FOV glass. The results of the experiment with the proposed methods have showed advantages with regards to the interaction performance as the scene became more complex and task more difficult. The work illustrates the concept of and potential for XR based interaction where the user can leverage the advantages of both VR and AR mode operations.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"39 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":"130766593","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}
