Such applications often include contact between multiple avatars or between avatars and objects as communication or gameplay. However, most current applications do not solve the effects of contact for avatars, causing penetration or unnatural behavior to occur. In reality, no contact with the player’s body occurs; nevertheless, the player must perform as if contact occurred. While physics simulation can solve the contact issue, the naive use of physics simulation causes tracking delay. We propose a novel avatar tracking controller with feedforward control. Our method enables quick, accurate tracking and flexible motion in response to contacts. Furthermore, the technique frees avatar performers from the loads of performing as if contact occurred. We implemented our method and experimentally evaluated the naturalness of the resulting motions and our approach’s effectiveness in reducing performers’ loads.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126363747","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}

Our approach replaces complex objects by impostors, light-weight image-based representations leveraging geometry and shading related processing costs. In contrast to their classical implementation, our impostors are specifically designed to work in Virtual-, Augmented- and Mixed Reality scenarios (XR for short), as they support stereoscopic rendering to provide correct depth perception. Motion parallax of typical head movements is compensated by using a ray marched parallax correction step. Our approach provides a dynamic run-time recreation of impostors as necessary for larger changes in view position. The dynamic run-time recreation is decoupled from the actual rendering process. Hence, its associated processing cost is therefore distributed over multiple frames. This avoids any unwanted frame drops or latency spikes even for impostors of objects with complex geometry and many polygons. In addition to the significant performance benefit, our impostors compare favorably against the original mesh representation, as geometric and textural temporal aliasing artifacts are heavily suppressed.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"10 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124736124","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}

As a method to enhance the VR experience, we focused on loud vocalization. This is because we believe that loud vocalization can enable us to engage with the VR environment in a more interactive way. Also, as loud vocalization is an action that is thought to be closely related to stress reduction and a sense of exhilaration, the stress reduction through VR with loud vocalization is also expected. But loud vocalization itself has disadvantages for physical, mental, and social reasons. Then, we hypothesized that loud vocalization itself is not necessary for such benefits; but the sense of loud vocalization plays an important role. Therefore, we focused on a method of substituting experience by presenting sensory stimuli. In this paper, we proposed a way to present the sense of loud vocalization through vibratory stimuli to the larynx and auditory stimuli to users who are actually vocalizing quietly with the expectation for the sense of loud vocalization. Our user study showed that the proposed method can extend the sense of vocalization and realize pseudo-loud vocalization. In addition, it was also shown that the proposed method can cause a sense of exhilaration. By contrast, excessively strong vibratory stimuli spoil the sense of loud vocalization, and thus the intensity of the vibration should be appropriately determined.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"415 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124817649","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}
