However, most studies are limited to two-dimensional guidance when many interactions happen in 3D spaces. Moreover, visual feedback that is often used to communicate the 3D position of a particular object may not be available in situations when the target is occluded by other objects or located outside of one’s field of view, or due to visual overload or light conditions. Inspired by a prior finding that showed users’ tendency of scanning a 3D space in one direction at a time, we propose two-step nonvisual omnidirectional guidance feedback designs varying the searching order where the guidance for the vertical location of the target (the altitude) is offered to the users first, followed by the horizontal direction of the target (the azimuth angle) and visa versa. To investigate its effect, we conducted the user study with 12 blind-folded sighted participants. Findings suggest that our proposed two-step guidance outperforms the default condition with no order in terms of task completion time and travel distance, particularly when the guidance in the horizontal direction is presented first. We plan to extend this work to assist with finding a target in 3D spaces in a real-world environment.","PeriodicalId":395413,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131302787","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 full-body avatars are often sought to be used in applications, low visibility avatars (i.e., head and hands) are often used in a variety of contexts, either as intentional design choices, for simplicity in contexts where full-body avatars are not needed, or due to external limitations. Avatar style can also vary from more simplistic and abstract to highly realistic depending on application context and user choices. We present the results of two desktop experiments that examine avatar visibility, style, and observer view on accuracy in a pointing interpretation task. Significant effects of visibility were found, with effects varying between horizontal and vertical components of error, and error amounts not always worsening as a result of lowering visibility. Error due to avatar visibility was much smaller than error resulting from avatar style or observer view. Our findings suggest that humans are reasonably able to understand pointing gestures with a limited observable body.","PeriodicalId":395413,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127001922","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}

This presents challenges when another person in the same physical space needs to interrupt the VR user for a brief conversation. Such interruptions, e.g., tapping a VR user on the shoulder, can cause a disruptive break in presence (BIP), which affects their place and plausibility illusions, and may cause a drop in performance of their virtual activity. Recent findings related to the concept of diegesis, which denotes the internal consistency of an experience/story, suggest potential benefits of integrating registered virtual representations for physical interactors, especially when these appear internally consistent in VR. In this paper, we present a human-subject study we conducted to compare and evaluate five different diegetic and non-diegetic methods to facilitate cross-reality interruptions in a virtual office environment, where a user’s task was briefly interrupted by a physical person. We created a Cross-Reality Interaction Questionnaire (CRIQ) to capture the quality of the interaction from the VR user’s perspective. Our results show that the diegetic representations afforded reasonably high senses of co-presence, the highest quality interactions, the highest place illusions, and caused the least disruption of the participants’ virtual experiences. We discuss our findings as well as implications for practical applications that aim to leverage virtual representations to ease cross-reality interruptions.","PeriodicalId":395413,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125491883","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 RDW, the contradiction between vestibular inputs and visual sensations may make users notice the RDW manipulation, resulting in discomfort throughout the experience. Because humans integrate multisensory information by considering the reliability of each modality, by reducing the effects of vestibular inputs on self-motion perception, it is possible to suppress awareness of and discomfort during RDW manipulation and improve the effectiveness of the manipulation. Therefore, we hypothesized that adding noise to the vestibular inputs would reduce the reliability of the vestibular sensations and enhances the effectiveness of RDW by improving the relative reliability of vision. In this study, we used noisy galvanic vestibular stimulation (GVS) to reduce the reliability of vestibular inputs. GVS is a method of stimulating vestibular organs and nerves by applying small electrical currents to the bilateral mastoid. To reduce the reliability of vestibular inputs, we employed noisy GVS whose current pattern is white noise. We experimented with comparing the threshold of curvature gains between noisy GVS conditions and a control condition.","PeriodicalId":395413,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124131780","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, these results indicating that VR tracking data should be understood as personally identifying data were based on observing 360° videos. In this paper, we present results based on sessions of user tracking data from an ecologically valid VR training application, which indicate that the prior claims may not be as applicable for identifying users beyond the context of observing 360° videos. Our results indicate that the degree of identification accuracy notably decreases between VR sessions. Furthermore, we present results indicating that user tracking data can be obfuscated by encoding positional data as velocity data, which has been successfully used to predict other user experience outcomes like simulator sickness and knowledge acquisition. These results, which show identification accuracies were reduced by more than half, indicate that velocity-based encoding can be used to reduce identifiability and help protect personal identifying data.","PeriodicalId":395413,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133280723","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}
