As local spaces are specific to each user, sharing a virtual environment with others for collaborative work or games becomes complicated. It is not clear which user's walkable space to prefer, or whether that space will be navigable for both users. This paper presents a technique which allows users to interact in virtual reality while each has a different walkable space. With this method mappings are created between pairs of environments. Remote users are then placed in the local environment as determined by the corresponding mapping. A user study was conducted with 38 participants. Pairs of participants were invited to collaborate on a virtual reality puzzle-solving task while in two different virtual rooms. An avatar representing the remote user was mapped into the local user's space. The results suggest that collaborative systems can be based on local representations that are actually quite different.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"50 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":"125455216","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}

To obtain many views or \"likes\", attractive photos should be posted. However, some casual foods are served with utensils on a plate or a bowl at restaurants, which spoils attractiveness of meal photos. Especially in Japan where ramen noodle is the most popular casual food, ramen is usually served with a ramen spoon in a ramen bowl in a ramen noodle shop. This is a big problem for SNS photographers, because a ramen spoon soaked in a ramen bowl extremely degrades the appearance of ramen photos. Then, in this paper, we propose anapplication called \"ramen spoon eraser\" that erases a spoon from ramen photos with spoons using a CNN-based Image-to-Image translation network. In this application, it is possible to automatically erase ramen spoons from ramen photos, which extremely improve the attractiveness of ramen photos. In the experiment, we train models in two ways as CNN-based Image-to-Image translation networks with the dataset consisting of ramen images with / without spoons collected from the Web.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"179 5 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":"124253643","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 languages like Korean and Japanese, it is used in everyday conversation to emphasize certain situation and enrich the prose. In this poster, we explore if the use of onomatopoeia, visualized and added to the usual sound feedback, could be taken advantage to increase or alter the perceived realism of the sound feedback itself, and furthermore of the situation at hand in virtual reality. A pilot experiment was run to compare the user's subjective perceived realism and experience under four test conditions of presenting a simple physical interaction, accompanying it with: (1) just the \"as-is\" sound (baseline), (2) \"as-is\" sound and onomatopoeia, (3) a representative sound sample (e.g. one for all different collision conditions), and (4) a representative sound sample and onomatopoeia. Our pilot study has found that the use of onomatopoeia can alter and add on to the perceived realism/naturalness of the virtual situation such that the experiences of the single representative sound added with the onomatopoeia and \"as-is\" sound were deemed similar.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"61 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":"128379643","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 have implemented our prototyping system with Unity and C# programming language for use with Oculus Go.

However, previous research has primarily focused on WIP during forward movement and tasks involving turning. Thus, little is known about what gestures to use in combination with WIP in order to enable sidestepping. This paper presents two user studies comparing three different types of gestures based on movement of the hip, leaning of the torso, and actual sidesteps. The first study focuses on purely lateral movement while the second involves both forward and lateral movement. The results of both studies suggest that leaning yielded significantly more natural walking experiences and this gesture also produced significantly less positional drift.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"257 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":"115009859","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}

This new type of immersive experience requires specific authoring tools. The traditional ones used in the movie and the video games industries were modified to support immersive visual and audio content. However, few solutions exist to edit haptic content, especially when the whole user's body is involved. To tackle this issue we propose HFX Studio, a haptic editor based on haptic perceptual models. Three models of pressure, vibration and temperature were defined to allow the spatialization of haptic effects on the user's body. These effects can be designed directly on the body (egocentric approach), or specified as objects of the scene (allocentric approach). The perceptual models are also used to describe capabilities of haptic devices. This way the created content is generic, and haptic feedback is rendered on the available devices. The concept has been implemented with the Unity®game engine, a tool already used in VR production. A qualitative pilot user study was conducted to analyze the usability of our tool with expert users. Results shows that the edition of haptic feedback is intuitive for these users.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"26 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":"115113552","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}

One particular task is constrained object manipulation, for which we conducted a user study. In it we compared standard gesture-based approaches with a touch-based interaction via smartphone. We found that a touch-based interface is significantly more efficient, although gestures are being subjectively more accepted.
