Depending on its context, a crowd can adopt different behaviors: it can be ambulant, aggressive, expressive or in an emergency situation, get into panic and flee. The main idea is to hold upon observations and assumptions made by crowd psychology studies in order to formulate a model up to reproduce as close as possible their behavior, depending on the context. To do so, we are considering the use of a microscopic model based on a scale concept: the Scale Based Model (SBM). This model is based on the psychological profile of the individuals to build crowds of different natures, crowds that will then have an influence on their own members. We will also bring up with the question of the model implementation in a real time environment.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117111119","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 provide full 3D manipulation by touch in an integral way, existing approaches use complex multi finger and hand gestures. However, they are difficult or impossible to use in one-handed handheld AR scenarios and their usage requires prior knowledge. Furthermore, a handheld's touch screen offers only two dimensions for interaction and limits manipulation to physical screen size. To overcome these problems, we present two novel intuitive six degree-of-freedom (6DOF) manipulation techniques, 3DTouch and HOMER-S. While 3DTouch uses only simple touch gestures and decomposes the degrees of freedom, Homer-S provides full 6DOF and is decoupled from screen input to overcome physical limitations. In a comprehensive user study, we explore performance, usability and accuracy of both techniques. Therefore, we compare 3DTouch with HOMER-S in four different scenarios with varying transformation requirements. Our results reveal both techniques to be intuitive to translate and rotate objects. HOMER-S lacks accuracy compared to 3DTouch but achieves significant performance increases in terms of speed for transformations addressing all 6DOF.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116231657","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 interaction techniques for mobile AR usually use the multi-touch capabilities of the device for object selection. However, single touch input is imprecise, but existing two handed selection techniques to increase selection accuracy do not apply for one-handed handheld AR environments. To address the requirements of accurate selection in a one-handed dense handheld AR environment, we present the novel selection technique DrillSample. It requires only single touch input for selection and preserves the full original spatial context of the selected objects. This allows disambiguating and selection of strongly occluded objects or of objects with high similarity in visual appearance. In a comprehensive user study, we compare two existing selection techniques with DrillSample to explore performance, usability and accuracy. The results of the study indicate that DrillSampe achieves significant performance increases in terms of speed and accuracy. Since existing selection techniques are designed for virtual environments (VEs), we furthermore provide a first approach towards a foundation for exploring 3D selection techniques in dense handheld AR.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124183768","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}

From prehistory up until the present day, random events, and technologically instantiated generative processes have operated in concert, extending the scope for the production of aesthetic objects of all kinds. In the last half-century of computational art, chance has played alongside generative computer programs -- a trend that looks set to continue. A range of works is explored here, highlighting the interaction between chance and dynamic processes to generate complex representations, virtual spaces and aesthetic artefacts. With this approach, the paper argues, chance and dynamics have the potential to continue as dominant creative forces into the future of art.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132065995","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 problem in addressing this question is that combining free movement with controlled stimulus conditions in navigation tasks is difficult to achieve. We have constructed a unique mixed reality space that answers this challenge. In our experiment we expose human subjects to a virtual house where they can navigate following two different protocols: guided or free navigation. We want to assess how navigation mode affects spatial memory. Our results show that the participants that were assigned to the guided navigation condition display higher spatial memory performance, as opposed to those assigned to the free navigation paradigm.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126524330","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}
