However, some users are susceptible to cybersickness, and this issue is particularly prominent if the user is physically stationary while virtually moving. One approach to minimizing cybersickness is to rotate the user in discrete steps. This poster presents a between-subjects study (n=42) comparing this approach to smooth virtual rotation. The results revealed a statistically significant increase in self-reported sickness after exposure to the VE in case of both conditions. No statistically significant differences between the two conditions were found.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121794350","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}

Compared to a single fixed-viewpoint color map, view-dependent texture mapping (VDTM) techniques can reproduce finer detail and replicate dynamic lighting effects that become especially noticeable with head tracking in virtual reality. However, VDTM is very sensitive to errors such as missing data or inaccurate camera pose estimation, both of which are commonplace for objects captured using consumer-grade RGB-D cameras. To overcome these limitations, our proposed optimization can synthesize a high resolution view-dependent texture map for any virtual camera location. Synthetic textures are generated by uniformly sampling a spherical virtual camera set surrounding the virtual object, thereby enabling efficient real-time rendering for all potential viewing directions.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131598973","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}

Here we present our ongoing work that aims to extend the simulation to outdoor scenes by using the Waveguide Web, instead of the original formulation with the Scattering Delay Networks.

The goal is to exploit the characteristics of the human vision to reduce the bandwidth required for the mobile provision of future data intensive services in Virtual Reality (VR).

Seated VR applications, specifically immersive 360 degree movies, must be appropriately designed to facilitate user comfort and prevent sickness. Our research explores a scene rotation-based method for redirecting a viewer's gaze and its effectiveness given three parameter adjustments: rotation delay, rotation speed, and angle threshold. The technique may be useful in the development of future immersive movie or VR experiences. From the research, we expect to discover which parameters prove most effective at redirecting a viewer's gaze in an immersive movie experience. We present preliminary developments and an informal usability evaluation to collect participant feedback about preference, comfort, and sickness.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121037367","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 has been shown that different environments or applications might benefit from direct manipulation approaches, while others might be more usable with indirect ones, exploiting, for example, three dimensional virtual widgets. When it comes to mid-air interactions, the success of a manipulation technique is not only defined by the kind of application but also by the hardware setup, especially when specific restrictions exist. In this paper we present an experimental evaluation of different techniques and hardware for mid-air object manipulation in immersive virtual environments (IVE). We compared task performances using both deviceless and device-based tracking solutions, combined with direct and widget-based approaches. We also tested, in the case of freehand manipulation, the effects of different visual feedback, comparing the use of a realistic virtual hand rendering with a simple cursor-like visualization.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"326 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225051","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}

Existing face manipulation applications and methods have some limitations: single photo, manipulation on image domain, or limited deformation. In the proposed framework, face is tracked from video by using landmark tracking and fitting 3d morphable face model to image, and the face model is further deformed according to the user input with mesh deformation method and rendered with texture from the frame image onto the camera preview. Therefore, unlike conventional applications and researches for face manipulation, the proposed framework allows the user to perform free-form 3d deformation of face in video and to view the deformed face at various viewpoints.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122335856","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}
