Previous works focus on 2D stitching or dynamic projection to 3D models, such as panorama and Augmented Virtual Environment (AVE), and haven't given an ideal solution. We present a novel method of multiple video fusion in 3D environment, which produces a highly comprehensive imagery and yields a spatio-temporal consistent scene. User initially interact with a newly designed background model named video model to register and stitch videos' background frames offline. The method then fuses the offline results to render videos in a real time manner. We demonstrate our system on 3 real scenes, each of which contains dozens of wide-baseline videos. The experimental results show that, our 3D modeling interface developed with the our presented model and method can efficiently assist the users to seamlessly integrate videos by comparing to commercial-off-the-shelf software with less operating complexity and more accurate 3D environment. The stitching method proposed by us is much more robust against the position, orientation, attribute differences among videos than the start-of-the-art methods. More importantly, this study sheds light on how to use the 3D techniques to solve 2D problems in realistic and we validate its feasibility.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116872969","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, to the best of our knowledge, there is no research on the validation of the cross-modal effects in AR and DR. Our research interest here is to investigate how this continuous visual changes between AR and DR would change our weight sensation of an object. In this paper, we built a system that can continuously extend and reduce the amount of visual entity of real objects using AR and DR renderings to confirm that users can perceive things heavier and lighter than they actually are in the same manner as SWI. Different from the existing research where either AR or DR visual effects were used, we validated one of cross-modal effects in the context of both continuous AR and DR visuo-haptic. Regarding the weight sensation, we found that such cross-modal effect can be approximated with a continuous linear relationship between the weight and length of real objects. Our experimental results suggested that the weight sensation is closely related to the positions of the center of gravity (CoG) and perceived CoG positions lie within the object's entity under the examined conditions.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127264918","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 central question of the study is whether the usability evaluation of a car entertainment system within a MR environment provides the same results as the evaluation of the car entertainment system within a real car. For this purpose a prototypical car infotainment system was built and integrated into a real car and into a MR environment. The MR environment represents the interior of the car and uses finger tracking and real haptic control elements of the center console of a car. Two test groups were assigned to the two different test environments. The study shows, that the usability is rated similar in both environments although readability and representation within the infotainment system is problematic.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"56 34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124952071","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}

It illustrates the method in which the app was created - using vector data and uploading it to MapBox, then accessing that data in Unity through the MapBox API and map editor and then overlaying the camera input with the navigation path layer. The application was tested by creating multiple arbitrary navigation scenarios and checking them for various factors. The main finding of this research is that this navigation solution works better than GPS indoor navigation.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114482866","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}

During development, scientists must precisely track their distribution in the body, a task that can be severely limited by traditional 2D displays. With its stereoscopic capacity and real-time interactivity, virtual reality (VR) provides an encouraging platform to accurately visualize dynamic 3D volumetric data. In this research, we develop a prototype application to track nanomedicines in VR. This platform has the potential to enhance data assessment, comprehension and communication in preclinical research which may ultimately influence the paradigm of future clinical protocols.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130316085","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 developed a video latency control system to film the user's hand movements and control the latency when displaying the video (The standard deviation is 0.38 ms). The minimum latency of the system is 4.3 ms, hence this enables us to investigate the performance for unknown low latency ranges. Using this system, we conducted experiments wherein 20 subjects performed a pointing task based on Fitts' law to clarify the effect of video latency, particularly for low latency. Experimental results showed that when the latency is over 24.3 ms, the user performance begins to decrease. This result will be applied to determine a standard limit for video latency in interactive video devices.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129404864","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}
