Such light fields are commonly sampled as a collection of 2D images. This sampling methodology inevitably gives rise to large data volumes, which in turn hampers real-time light field streaming over best effort networks, particularly the Internet. This paper advocates the packaging of the source images of a static light field as a segmented video sequence so that the light field can then be interactively network streamed in a quality-variant fashion using MPEG-DASH, the standardized HTTP Adaptive Streaming scheme adopted by leading video streaming services like YouTube and Netflix. We explain how we appropriate MPEG-DASH for the purpose of adaptive static light field streaming and present experimental results that prove the feasibility of our approach, not only from a networking but also a rendering perspective. In particular, real-time rendering performance is achieved by leveraging video decoding hardware included in contemporary consumer-grade GPUs. Important trade-offs are investigated and reported on that impact performance, both network-wise (e.g., applied sequencing order and segmentation scheme for the source images of the static light field) and rendering-wise (e.g., disk-versus-GPU caching of source images). By adopting a standardized transmission scheme and by exclusively relying on commodity graphics hardware, the net result of our work is an interoperable and broadly deployable network streaming solution for static light fields.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"4 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":"124206167","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}

Combinations of the visual, auditory and haptic feedback have successfully simulated experiences in VR, however, multimedia contents may also stimulate emotions. In this paper, we especially paid attention to negative emotions that may be perceived in such experiences (e.g., fear). We hypothesized that volunteering, visual, mechanical, and electrical feedback may induce negative emotional feedback to users. In-Pulse is a novel system and approach to explore the potential of bringing this emotional feedback to users. We designed a head-mounted display (HMD) combined with mechanical and electrical muscle stimulation (EMS) actuators. A user study was performed to explore the effect of our approaches with combinations with VR contents. The results suggest that mechanical actuators and EMS can improve the experience of virtual experiences.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"65 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":"130495373","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}

Co-presence, in a sense of perception of another person being present in the same virtual space is analyzed through subjective responses and behavioral markers. The results indicate that both perception and proxemics in relation to co-located and distributed players differ. The effect on the perception is however mitigated if participants do not collide with the avatars of distributed co-players.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"27 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":"127549684","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 the proposed method, a camera captures an image of objects in the real world. Next all the pixels in the image but those in a specified region are slightly shifted to left and right. Then the obtained image is projected onto the original objects. As a result, the objects not in the specified region looks blurred.

However, many questions remain open concerning the spatial location of haptics on the user's body in VR. We studied how simple vibrotactile collision feedback on two less studied locations, the temples, and the wrist, affects an object picking task in a VR environment. We compared visual feedback to three visual-haptic conditions, providing haptic feedback on the participants' (N=16) wrists, temples or simultaneously on both locations. The results indicate that for continuous, hand-based object selection, the wrist is a more promising feedback location than the temples. Further, even a suboptimal feedback location may be better than no haptic collision feedback at all.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"58 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":"124499739","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 a VAS people with disabilities perform tasks that are made easier in the virtual environment (VE) compared to the real world. We hypothesized that putting people with disabilities in a VAS will increase confidence and enable more efficient task completion than without a VAS. To investigate this hypothesis, we conducted a within-subjects experiment in which participants performed a virtual task called \"kick the ball\" in two different conditions: a no gain condition (i.e., same difficulty as in the real world) and a rotational gain condition (i.e., physically easier than the real world but visually the same). The results from our study suggest that VAS increased participants' confidence which in turn enables them to perceive the difficulty of the same task easier.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"23 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":"114605166","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}
