Emergency situations caused by mass casualty events (e.g., natural disasters) introduce additional difficulties to handoff procedures such as environmental noise. We created a projected mixed reality simulation of a handoff scenario involving a medical evacuation by air and tested how low, medium, and high levels of helicopter noise affected participants’ handoff experience, handoff performance, and behaviors. Through a human-subjects experimental design study (N = 21), we found that the addition of noise increased participants’ subjective stress and task load, decreased their self-assessed and actual performance, and caused participants to speak louder. Participants also stood closer to the virtual human sending the handoff information when listening to the handoff than they stood to the receiver when relaying the handoff information. We discuss implications for the design of handoff training simulations and avenues for future handoff communication research.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"14 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":"115331332","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 classical FOV restrictor is implemented using a symmetric mask that occludes the periphery in response to translational and/or angular velocity. In this paper, we introduce adaptive field-of-view restriction, a novel technique that responds dynamically based on real-time assessment of optical flow generated by movement through a virtual environment. The adaptive restrictor utilizes an asymmetric mask to obscure regions of the periphery with higher optical flow during virtual locomotion while leaving regions with lower optical flow visible. To evaluate the proposed technique, we conducted a gender-balanced user study (N = 38) in which participants completed in a navigation task in two different types of virtual scenes using controller-based locomotion. Participants were instructed to navigate through either close-quarter or open virtual environments using adaptive restriction, traditional symmetric restriction, or an unrestricted control condition in three VR sessions separated by at least 24 hours. The results showed that the adaptive restrictor was effective in mitigating cybersickness and reducing subjective discomfort, while simultaneously enabling participants to remain immersed for a longer amount of time compared to the control condition. Additionally, presence ratings were significantly higher when using the adaptive restrictor compared to symmetric restriction. In general, these results suggest that adaptive field-of-view restriction based on real-time measurement of optical flow is a promising approach for virtual reality applications that seek to provide a better cost-benefit tradeoff between comfort and a high-fidelity experience.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"79 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":"134004846","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 contrast, hand-controlled avatars give more dexterous and fewer fatigue manipulations within a close-range space for avatar control but provide fewer sensory cues than the body-based method. This paper investigates the differences between the two manipulations and explores the possibility of a combination. We first performed a formative study to understand when and how users prefer manipulating hands and bodies to represent avatars’ actions in current popular video games. Based on the top video games survey, we decided to represent human avatars’ motions. Besides, we found that players used their bodies to represent avatar actions but changed to using hands when they were too unrealistic and exaggerated to mimic by bodies (e.g., flying in the sky, rolling over quickly). Hand gestures also provide an alternative to lower-body motions when players want to sit during gaming and do not want extensive effort to move their avatars. Hence, we focused on the design of hand gestures and upper-body postures. We present Puppeteer, an input prototype system that allows players directly control their avatars through intuitive hand gestures and upper-body postures. We selected 17 avatar actions discovered in the formative study and conducted a gesture elicitation study to invite 12 participants to design best representing hand gestures and upper-body postures for each action. Then we implemented a prototype system using the MediaPipe framework to detect keypoints and a self-trained model to recognize 17 hand gestures and 17 upper-body postures. Finally, three applications demonstrate the interactions enabled by Puppeteer.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"14 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":"133160849","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}
