More complex collaborative tasks may require individual user navigation to achieve loosely-coupled collaboration. We designed a navigation framework based on the human joystick metaphor with some alterations for cohabitation management. This model allows each user to navigate independently using a human joystick based control while avoiding physical obstacles and staying within the usable part of the system. We conducted a series of user studies to investigate the influence of each alteration by testing their combinations on various navigation tasks. The results show that modified transfer functions and adaptive neutral orientations improve users' cohabitation performance, while the impact of adaptive neutral positions need to be further studied.","PeriodicalId":178186,"journal":{"name":"2016 IEEE Third VR International Workshop on Collaborative Virtual Environments (3DCVE)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132597874","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}

They have been the subject of research activities that have led to some interesting results described in the literature. Unfortunately, most of these results have not yet been not implemented in the software systems daily used by industry and remains only theoretical concepts. That is why we recently started a project to transfer some of these results in the aerospace industry for the Airbus Group. Beyond this first transfer target, we also intend to measure the real gains (in real industrial conditions) for the users, and then for the company. This second goal is essential because in most publications, user testing is not satisfying (lack of real users, lack of real procedures, non significant number of subjects). In this paper, we describe the first step of this work in progress and more precisely, the basic interaction features we have developed. Currently, we are designing the first user tests.","PeriodicalId":178186,"journal":{"name":"2016 IEEE Third VR International Workshop on Collaborative Virtual Environments (3DCVE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121252886","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 goal is to benefits from the wide variety of todays VR devices. Therefore, our solution is based on an asymmetric collaboration pattern at different scales in which users benefit from suited points of views and interaction techniques according to their device setups. Indeed, each user application is adapted thanks to plasticity mechanisms. Our system provides an efficient way to co-manipulate an object within irregular and narrow courses, taking advantages of asymmetric roles in synchronous collaboration. Moreover, its aims to provide a way to maximize the filling of the courses while the object moves on its path.","PeriodicalId":178186,"journal":{"name":"2016 IEEE Third VR International Workshop on Collaborative Virtual Environments (3DCVE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128400856","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 this paper, we present our novel interaction paradigm called Vishnu that aims to ease collaborative remote guiding. We focus on collaborative remote maintenance as an illustrative use case. It relies on an expert immersed in Virtual Reality (VR) in the remote workspace of a local agent helped through an Augmented Reality (AR) interface. The main idea of the Vishnu paradigm is to provide the local agent with two additional virtual arms controlled by the remote expert who can use them as interactive guidance tools. Many challenges come with this: collocation, inverse kinematics (IK), the perception of the remote collaborator and gestures coordination. Vishnu aims to enhance the maintenance procedure thanks to a remote expert who can show to the local agent the exact gestures and actions to perform. Our pilot user study shows that it may decrease the cognitive load compared to a usual approach based on the mapping of 2D and de-localized informations, and it could be used by agents in order to perform specific procedures without needing to have an available local expert.","PeriodicalId":178186,"journal":{"name":"2016 IEEE Third VR International Workshop on Collaborative Virtual Environments (3DCVE)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124642872","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}
