In particular, we evaluate the factors that seem to make the mouse a good input device for constrained 3D movement tasks. The first study examines the effect of a supporting surface across orientation of input device movement and display orientation. Surprisingly, no significant results were found for the effect of physical support for constrained movement techniques. Also, no significant difference was found between matching the orientation of the display to that of the input device movement. A second study found that the mouse outperformed all tracker conditions for speed, but the presence or absence of support had no significant effect when tracker movement is constrained to 2D.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125006623","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}

A whole application is then obtained as a composition of such defined components. To ease writing specifications, we propose a textual language (named MIRELA: mixed reality language) along with the corresponding compilation tools. The generated output contains timed automata in UPPAAL format for simulation and verification of time constraints, and which also may be used to generate source code skeletons for an implementation on a MR platform.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130431760","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}

Previous studies showed that MR was preferred for collocated collaboration while immersive virtual reality was preferred for remote collaboration. The main reason for this preference is that the physical object in remote space cannot be handled directly. However, MR using tangible objects is still attractive for remote collaborative systems, because MR enables seamless interaction with real objects enhanced by virtual information with the sense of touch. Here we introduce \"tangible replicas\"(dual objects that have the same shape, size, and surface), and propose a symmetrical model for remote collaborative MR. The result of experiments shows that pointing and drawing functions on the tangible replica work well despite limited shared information.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123792859","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}

Various theories as to why this might occur have been investigated, but to date the cause is not fully understood. A much smaller number of studies have investigated how depth perception operates in augmented reality (AR), and some of these studies have also indicated a similar underestimation effect. In this paper we report an experiment that further investigates these effects. The experiment compared VR and AR conditions to two real-world control conditions, and studied the effect of motion parallax across all conditions. Our combined VR and AR head-mounted display (HMD) allowed us to develop very careful calibration procedures based on real-world calibration widgets, which cannot be replicated with VR-only HMDs. To our knowledge, this is the first study to directly compare VR and AR conditions as part of the same experiment.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114338814","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 system combines interactive 3D graphics with haptic force feedback and provide several virtual tools for the manipulation of 3D objects represented by irregular triangle meshes. The current functionality includes mesh painting with pressure dependent brush size and paint preview, mesh cutting via drawing a poly-line on the model and two types of mesh deformations. We use two phantoms, either in a co-located haptic/3D-stereo setup or as a fish tank VR setup with a 3D flat panel. In our system, the second hand assists the manipulation of the object, either by \";holding\"; the mesh or by affecting the manipulation directly. While the connection of 3D artists and designers to such a direct interaction system may be obvious, we are also investigating its potential benefits for landscape architects and other users of spatial geoscience data. Feedback from an upcoming user study will evaluate the benefits of this system and its tools for these different user groups.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121421221","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}

Yet, developing such an application is often done without reusing existing components, which requires a huge amount of time. We present in this paper a full authoring platform to facilitate the development of both new virtual environments and pedagogical information for procedural training. This platform, named GVT (generic virtual training) relies on innovative models and provides authoring tools which allow capitalizing on the developments realized. We present a generic model named STORM, used to describe reusable behaviors for 3D objects and reusable interactions between those objects. We also present a scenario language named LORA which allows non computer scientists to author various and complex sequences of tasks in a virtual scene. Based on those models, as an industrial validation with Nexter-Group, more than fifty operational scenarios of maintenance training on military equipments have been realized so far. We have also set up an assessment campaign, and we expose in this paper the first results which show that GVT enables trainees to learn procedures efficiently. The platform keeps on evolving and training on collaborative procedures will soon be available.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128630989","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}

MGDs explicitly showed the groups that people had formed themselves into, and helped people move around together and communicate over extended distances. The techniques were evaluated in the context of an urban planning application, by providing one batch of participants with MGDs and another with an interface based on conventional collaborative virtual environments (CVEs). Participants with MGDs spent nearly twice as much time in close proximity (within 10m of their nearest neighbor), communicated seven times more than participants with a conventional interface, and exhibited real-world patterns of behavior such as staying together over an extended period of time and regrouping after periods of separation. The study has implications for CVE designers, because it shows how MGDs improves groupwork in CVEs.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129740927","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}
