Using the game engine \"Unity\", we proposed a method of embedding recorded sound sources into virtual objects placed in a virtual space, and sequentially playing back the sound when the user walks or turns around in the virtual space. By using this system, it is possible to reproduce the same sound field in the virtual space as in the real space, and it can be applied in various places.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"44 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":"133799058","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, users sometimes immerse in the navigation interface and ignore probable dangers in the real environment. It is necessary to remind users of potential dangers and avoid accidents. Most of existing works focus on how to effectively guide users in AR but few concern about design of danger reminder. In this paper, we build a virtual AR navigation system and compare user experience on different types of obstacle reminder. Furthermore, we compare the influence of color, motion and appearance distance on effectiveness of the reminder. Results show that red color and bi-color are more obvious than blue color for reminder. Motion such as flickering effect helps enhance remind effectiveness.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"15 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":"134179721","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}

Virtual meeting tools start popularizing and thriving. Those tools allow users to see each other through screen and camera, chat through voice and text, and share content or ideas through screen share. However, screen sharing protein models through virtual meetings is not easy due to the difficulty of viewing protein 3D (Three Dimensional) structures from a 2D (Two Dimensional) screen. Moreover, interactions upon a protein are also limited. ProMVR is a tool the author developed to tackle the issue that protein designers may find limitations working in a traditional 2D or 3D environment and they may find it hard to communicate their ideas with other designers. Since ProMVR is a VR tool, it allows users to “jump into” a virtual environment, take a close look at protein models, and have intuitive interactions.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"50 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":"134276348","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}

{"title":"opticARe - Augmented Reality Mobile Patient Monitoring in Intensive Care Units","authors":"S. Kimmel, Vanessa Cobus, Wilko Heuten","doi":"10.1145/3489849.3489852","DOIUrl":"https://doi.org/10.1145/3489849.3489852","url":null,"abstract":"German Intensive Care Units (ICUs) are in crisis, struggling with an increasing shortage of skilled workers, ultimately putting patients’ safety at risk. To counteract this process, researchers are increasingly concerned with finding digital solutions which aim to support healthcare professionals by enhancing the efficiency of reoccurring critical caring tasks and thus, improve working conditions. In this regard, this paper evaluates the application of Augmented Reality (AR) for patient monitoring for critical care nursing. Grounded on an observational study, semi-structured interviews, as well as a quantitative analysis, mobile patient monitoring scenarios, present particularly during patient transport, were identified as an innovative context of use of AR in the field. Additionally, user requirements such as high wearability, hands-free operability, and clear data representation could be derived from the obtained study results. For validation of these and identification of further requirements, three prototypes differing in their data illustration format were subsequently developed and quantitatively, as well as qualitatively evaluated by conducting an online survey. Thereby, it became evident that future implementations of a corresponding system for patient monitoring ought to integrate a context-dependent data presentation in particular, as this combines high navigability and availability of required data. Identifying patient monitoring during patient transport as a potential context of use, as well as distinguishing a context-dependent design approach as favorable constitute two key contributions of this work and provide a foundation on which future implementations of AR systems in the nursing domain and other related contexts can be established.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"12 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":"122505048","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}

Such AR systems based on SLAM technology are generally implemented by augmenting virtual objects onto a diorama or three-dimensional sculpture. However, a new SLAM map needs to be generated if the space or lighting where the diorama is installed changes. This leads to the problem of updating the coordinate system each time a new SLAM map is generated. Updates to the coordinate system signify that the positions of the virtual objects placed in the AR space change as well. Therefore, we proposed a SLAM map regeneration technique in which the existing coordinate system is maintained even if a new map is generated.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"12 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":"125062584","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 paper contributes a new method of applying VR to crowd source detection of physical environment vulnerabilities. We detail the technical realization of two BreachMob prototypes (a home and an airport) reflecting on static and dynamic vulnerabilities. Our design critique suggests that BreachMob promotes user immersion by allowing participants the freedom to behave in ways that align with the experience of breaching physical security protocols.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"40 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":"128369779","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}

Pirker","doi":"10.1145/3489849.3489884","DOIUrl":"https://doi.org/10.1145/3489849.3489884","url":null,"abstract":"Researchers study the user experience in Virtual Reality (VR) typically by collecting either sensory data or using questionnaires. While traditional questionnaire formats present it through web-based survey tools (out-VR), recent studies investigate the effects of presenting questionnaires directly in the virtual environment (in-VR). The in-VR questionnaire can be defined as an implemented user-interface object that allows interaction with questionnaires in VR that do not break the immersion. Integrating questionnaires directly into the virtual environment, however, also challenges design decisions. While most previous research presents in-VR questionnaires in the form of 2D panels in the virtual environment, we want to investigate the difference from such traditional formats to a presentation of a questionnaire format in the form of an interactive object as part of the environment. Accordingly, we evaluate and compare two different in-VR questionnaire designs and a traditional web-based form (out-VR) to assess user experience, the effect on presence, duration of completing the questionnaires, and users’ preferences. As the means for achieving this goal, we developed an immersive questionnaire toolkit that provides a general solution for implementing in-VR questionnaires and exchanging data with popular survey services. This toolkit enables us to run our study both on-site and remotely. As a first small study, 16 users, either on-site or remotely, attended by completing the System Usability Scale, NASA TLX, and the iGroup Presence Questionnaire after a playful activity. The first results indicate that there is no significant difference in the case of usability and presence between different design layouts. Furthermore, we could not find a significant difference also for the task load except between 2D and web-based layout for mental demand and frustration as well as the duration of completing the questionnaire. The results also indicate that users generally prefer in-VR questionnaire designs to the traditional ones. The study can be expanded to include more participants in user studies as a means of gaining more concrete results. Furthermore, additional questionnaire design alternatives can also help to provide us with a more usable and accurate questionnaire design in VR.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"29 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":"125337952","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 this work we evaluate two methods for manipulating virtual objects of varying sizes. World Pull enables the user to directly manipulate and scale the virtual environment, while Pivot Manipulation enables the user to rotate objects around a set of predefined pivot points. The methods were compared to a traditional 6 degree of freedom manipulation method during a user study and the results showed that World Pull performed better in terms of precision for small and large objects, while Pivot Manipulation performed better for large objects.","PeriodicalId":345527,"journal":{"name":"Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology","volume":"43 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":"121960089","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}
