Its millimetric spatial resolution is at the cost of several constraints: participants must remain static and experience artificial stimuli, making it difficult to generalize neuroscientific results to naturalistic and ecological conditions. Immersive Virtual Reality (VR) provides alternatives to such stimuli through simulation, but still requires an active first-person exploration of the environment to evoke a strong sense of presence in the virtual environment. Here, we report how to compensate for the inability to freely move in VR by leveraging on principles of embodiment for a virtual avatar, to eventually evoke a strong sense of presence with a minimal motion of the participant. We validated the functionality of the platform in a study where healthy participants performed several basic research tasks in an MR-specific immersive virtual environment. Our results show that our approach can lead to high sense of presence, strong body ownership, and sense of agency for a virtual avatar, with low movement-related MRI artifacts. Moreover, to exemplify the versatility of the platform, we reproduced several behavioral and fMRI results in the perceptual, motor, and cognitive domains. We discuss how to leverage such technology for neuroscience research and provide recommendations on efficient ways to implement and develop it successfully.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"17 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":"123665496","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}

Therefore, the observer perceives a mismatch in depth perception, which impairs usability. In this study, we developed an optical-reflection AR display, ALiSE (Augment Layer interweaved Semi-reflecting Existence), which enhances the depth perception experience of AR images by adding a gap zone with the same depth as the target depth between the display and the half-mirror. We conducted an experiment to view 3D objects and achieve virtual fitting using the existing AR with video synthesis and the proposed ALiSE method. As a result of the questionnaire survey, although the comfort of wearing virtual objects was below existing methods, we confirmed that the presence and solidity were superior with the proposed method to other approaches. This is an attempt to create a sense of the stereoscopic effect despite the 2D projection, as the object to be projected is simultaneously reflected in the mirror along with the observer themselves.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"24 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":"122063537","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}

However, it is not clear how we should conceptualise these interactions. They could be considered either gestures, as there is no interaction with a physical object; or as actions, given that there is object manipulation, even if it is virtual. This distinction is important, as literature has shown that in the physical world, action-enabled and gesture-enabled learning produce distinct cognitive outcomes. This study attempts to understand whether sensorimotor-embodied interactions with objects in IVR can cognitively be considered as actions or gestures. It does this by comparing verb-learning outcomes between two conditions: (1) where participants move the controllers without touching virtual objects (gesture condition); and (2) where participants move the controllers and manipulate virtual objects (action condition). We found that (1) users can have cognitively distinct outcomes in IVR based on whether the interactions are actions or gestures, with actions providing stronger memorisation outcomes; and (2) embodied controller actions in IVR behave more similarly to physical world actions in terms of verb memorization benefits.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"1 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":"128731736","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}
