Yet, little is known about the features of immersive technologies that contribute to successful place-based learning. Immersive technologies afford embodied experiences by mimicking natural embodied interactions through a user's egocentric perspective. Additionally, they allow for beyond reality experiences integrating contextual information that cannot be provided at actual field sites. The current study singles out one aspect of place-based learning: Scale. In an empirical evaluation, scale was manipulated as part of two immersive virtual field trip (iVFT) experiences in order to disentangle its effect on place-based learning. Students either attended an actual field trip (AFT) or experienced one of two iVFTs using a head-mounted display. The iVFTs either mimicked the actual field trip or provided beyond reality experiences offering access to the field site from an elevated perspective using pseudo-aerial 360° imagery. Results show that students with access to the elevated perspective had significantly better scores, for example, on their spatial situation model (SSM). Our findings provide first results on how an increased (geographic) scale, which is accessible through an elevated perspective, boosts the development of SSMs. The reported study is part of a larger immersive education effort. Inspired by the positive results, we discuss our plan for a more rigorous assessment of scale effects on both self- and objectively assessed performance measures of spatial learning.","PeriodicalId":315935,"journal":{"name":"2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126826561","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, when the head and cameras rotate, the captured image in buffers is degraded by latency and motion blur, which may cause VR sickness. In the present study, we propose a method named TwinCam in which we use two 360° cameras spaced at the standard interpupillary distance and keep the direction of the lens constant in the world coordinate even when the camera bodies are rotated to reflect the orientation of the observer's head and the position of the eyes. We consider that this method can suppress the image buffer size to send to the observer because each camera captures the omnidirectional image without lens rotation. This paper introduces the mechanical design of our camera system and its potential for visual telepresence through three experiments. Experiment 1 confirmed the requirement of a stereoscopic rather than monoscopic camera for highly accurate depth perception, and Experiments 2 and 3 proved that our mechanical camera setup can reduce motion blur and VR sickness.","PeriodicalId":315935,"journal":{"name":"2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126840765","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}

Multi-user virtual reality and serious game technologies can be used to provide collaborative training in dynamic settings [1], [2]. However, actual training effects seem to depend on a high presence and supportive usability [2]. EPICSAVE Lifesaving Decisions shows a novel approach that aims at further improving on these factors using an emotional scenario and collaborative game mechanics. We present a trailer video of a game sketch which creatively explores serious game design for collaborative virtual reality training systems. The game invites two paramedic trainees and one paramedic trainer into a dramatic scenario at a family theme park: A 5-year old child shows symptoms of anaphylactic shock. While the trainees begin their diagnostics procedures, a bystander, the girl's grandfather, intervenes and challenges the players' authority. Our research explores how VR game mechanics, i.e., optional narrative, authority skills and rewards, mini games, and interactive virtual characters may extend training quality and user experience over pure VR training simulations. The video exemplifies a concept that extends prior developments of a multi-user VR training simulation setup presented in [2], [3].","PeriodicalId":315935,"journal":{"name":"2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121264306","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}
