Large-screen displays typically make direct blind walking tasks impossible, despite them being a popular distance response measure in the real world and in head-mounted displays. We use a movable large-screen display to compare direct blind walking and indirect triangulated pointing with monoscopic viewing. We find that participants judged distances to be 89.4% ± 28.7% and 108.5% ± 44.9% of their actual distances in the direct blind walking and triangulated pointing conditions, respectively. However, we find no statistically significant difference between these approaches. This work adds to the limited number of research studies on egocentric distance judgments with a large display wall for distances of 3-5 meters. It is the first, to our knowledge, to perform direct blind walking with a large display.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114990042","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}

When teleporting, the user indicates the intended location in the virtual environment and is instantly transported, typically without self-motion cues. This project explored the cost of teleporting on the acquisition of survey knowledge (i.e., a ”cognitive map”). Two teleporting interfaces were compared, one with and one without visual and body-based rotational self-motion cues. Both interfaces lacked translational self-motion cues. Participants used one of the two teleporting interfaces to find and study the locations of six objects scattered throughout a large virtual environment. After learning, participants completed two measures of cognitive map fidelity: an object-to-object pointing task and a map drawing task. The results indicate superior spatial learning when rotational self-motion cues were available. Therefore, virtual reality developers should strongly consider the benefits of rotational self-motion cues when creating and choosing locomotion interfaces.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117270613","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}

Understanding swarms is of utmost importance in many disciplines and jobs, but hard to teach due to the elusive nature of the phenomenon, which requires to observe events at different scales (i.e., from different perspectives) and to understand the links between them. In this article, we investigate the potential of combining a swarm of tangible, haptic-enabled robots with Virtual Reality, to provide a user with multiple perspectives and interaction modalities on the swarm, ultimately aiming at supporting the learning of emergent behaviours. The framework we developed relies on Cellulo robots and Oculus Quest and was preliminarily evaluated in a user study involving 15 participants. Results suggests that the framework effectively allows users to experience the interaction with the swarm under different perspectives and modalities.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130247897","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}

Clients on various devices connect with servers for different functionalities tailored for various user groups. A demonstration with a local urban planning use-case shows the costs and benefits of BUDI as a spatial-based collaborative platform. We consider the trade-offs encountered when trying to make the collaboration seamless.

However, current object selection techniques suffer from issues of hand jitter, accuracy, and fatigue, especially to select nail-size objects. Here, we present locked dwell time-based point and tap, a novel object selection technique designed for nail-size object selection in a dense virtual environment. The objects are within arm’s reach. We also compare locked dwell time-based point and tap with magnetic grasp, pinch and raycasting. 40 participants evaluated the effectiveness and efficiency of these techniques. The results found that locked dwell time-based point and tap took significantly less task completion time and error rate. It was also the most preferred and caused least effort among all the techniques. We also measured easy to use, easy to learn and perceived naturalness of the techniques.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"340 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133929974","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 demo, we present a data input method that takes advantage of 3D space by interacting with a keyboard with keys arranged in three dimensions. Each hand is covered by a hemisphere of keys based on the QWERTY layout, allowing users to type by moving their hands in a motion similar to punching. Although the goal is to achieve a gesture more akin to tapping, current controllers or hand tracking technology doesn't allow such high fidelity. Thus, the presented interaction using VR controllers is more comparable to punching.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122426849","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}

Simultaneously, AR/VR systems are increasingly being used in co-located, multi-user experiences, opening the possibility for opportunistic capture of other users. This is the core idea behind BodySLAM, which uses disparate camera views from users to digitize the body, hands and mouth of other people, and then relay that information back to the respective users. If a user is seen by two or more people, 3D pose can be estimated via stereo reconstruction. Our system also maps the arrangement of users in real world coordinates. Our approach requires no additional hardware or sensors beyond what is already found in commercial AR/VR devices, such as Microsoft HoloLens or Oculus Quest.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127983428","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}

We investigate the potential for situated video analytics, which involves the inspection of video data in the actual environment where the video was captured [14]. Our ultimate goal is to explore the means to visually explore video data effectively, in situated contexts. We first investigate the performance of visual analytic tasks in situated vs. non-situated settings. We find that participants largely benefit from environmental cues for many analytic tasks. We then pose the question of how best to represent situated video data. To answer this, in a design session we explore end-users’ views on how to capture such data. Through the process of sketching, participants leveraged being situated, and explored how being in-situ influenced the participants’ integration of their designs. Based on these two elements, our paper proposes the need to develop novel spatial analytic user interfaces to support situated video analysis.","PeriodicalId":157249,"journal":{"name":"Proceedings of the 2020 ACM Symposium on Spatial User Interaction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115875029","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 class culminated in a virtual poster session, using Spatial in MR to present project results, and we conducted a preliminary investigation of students experiences via interviews and questionnaires. Students reported that they had a good experience using MR for the poster session and that they thought it provided advantages over 2D video conferencing.
