However, it isolates users from the outside world and impedes them from collaborating with other users who might be outside of the VR experience and vice-versa. We implemented two systems where we explore how such an external user in the real world can interact across realities with a user immersed in virtual reality, either locally or remotely, in order to to share pinpoint locations. In the first we investigate three cross-reality techniques for the external user to draw the attention of their VR counterpart on specific objects present in the virtual environment (Voice, Highlight, and Arrow). Participants performed better overall and preferred the Arrow technique, followed by the Highlight technique. In the second system we expand on these two techniques to explore an even starker cross-reality interaction between users in VR and users interacting via a tablet computer to direct each other to pinpoint objects in the scene. We adapted the previous two techniques and implemented two others (Vision cone, Pointing) that support bi-directional communication between users. When it comes to bi-directional pinpointing, VR users still showed preference for the Arrow technique (now described as Pointing in Giant mode), while mobile users were split between the Vision cone and the Highlight techniques.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134624312","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 users explore virtual environments by walking they rely on stable visible landmarks to plan and execute their next movement. In my research I am developing novel methods to predict locomotion paths of human subjects for the immediate future, i.e. the next few seconds. I aim to connect different types of behavioral data (eye, hand, feet and head tracking) and test their reliability and validity for predicting walking behavior in virtual reality. Such a prediction will be very valuable for natural interaction, for example in redirected walking schemes.My approach begins with an evaluation of the quality of data gathered with current tracking methods. Informative experimental conditions need to be developed to find meaningful patterns in natural walking. Next, raw tracked data of different modalities need to be connected with each other and aggregated in a useful way. Thereafter, possible valid predictors need to be developed and compared to already functioning predicting algorithms (e.g. [2],[6],[12]). As a final goal, all valid predictors shall be used to create a prediction algorithm returning the most likely future path when exploring virtual environments.","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115039853","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 hypothesis is that giving inhabitants design solutions that would fit individual needs and aspirations, will increase their satisfaction with their house. To arrive at architectonically responsible house transformations, we used a shape grammar system for defining the possible modifications [1]. For empowering inhabitants to understand and explore these modifications to their housing and increase the potential of their participation [2], we developed a mockup tool that comprehends two main parts: shape generation and visualization. The shape generation component is currently a mockup simulation that reproduces some of the generation possibilities of the grammar. For visualizing the outcomes, we developed three different possibilities: i) a semi-immersive visualization where the user utilizes a smart phone to see a 360º render of the site; ii) a fully immersive visualization developed with Unity in which the user with a Head Mounted Display, can freely navigate through the final design; iii) a non-immersive screen-based visualization, where the user, with a tablet device, visualizes a static image of the final design. Interviews and tests with real inhabitants (n=12) were performed to assess user’s response to the potential of the tools and preliminary conclusions show that a tool like MyChanges would have acceptance among inhabitants [3].","PeriodicalId":256204,"journal":{"name":"2021 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121109088","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}
