The prototype aims at professional applications like architectural design, surgical planning and geological exploration. Its design was influenced by the analysis of user requirements and by the requirement for a natural interface. The prototype permits the user to navigate through 3D and 2D data in order to explore the internal structure. 3D navigation is accomplished by means of a natural selection of dynamically updated cross-sections. The user can navigate through these selected cross-sections of 2D data and can perform manipulations with them. As a proof of concept we focus on two disciplines, viz. architectural design and surgical planning. Our usability evaluation of the interaction styles demonstrates that they are perceived as useful and enjoyable additions to existing techniques in these disciplines.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124781894","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}

As key interaction techniques collision detection and soft tissue modeling are identified. For collision detection in EyeSi, an enhanced image-based approach for collisions between deformable surfaces and rigid objects is presented. By exploiting the computing power of graphics processing units, it achieves higher performance than existing geometry-based approaches. Deformation vectors are computed and used for the biomechanical model. A mass-spring approach is shown to be powerful enough to bridge the gap between low computational demands and a convincing tissue behavior.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128054268","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 framework manages many multi-sensorial devices such as trackers, data gloves, and speech or gesture recognition systems as well as haptic devices. The structure of this architecture allows a complete dispatching of device services and their clients on as many machines as required. With the dated events provided by its time synchronization system, it becomes possible to design a specific module to manage multimodal fusion processes. To this end, we describe how the EVI3d framework manages not only low-level events but also abstract modalities. Moreover, the data flow service of the EVI3d framework solves the problem of sharing the virtual scene between modality modules.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134217314","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}

Seventeen subjects were recruited at University College London, who worked with a confederate at University of North Carolina Chapel Hill. Each pair was required to negotiate the task of handling an object together, and moving a few metres into a building. The DIVE system was used throughout, and the network support was Internet-2. This was an observational study to examine the extent to which such collaboration was possible, to explore the limitations of DIVE within this context, and to examine the relationship between several variables such as co-presence and task performance. The results suggest that although the task is possible under this framework, it could only be achieved by various software tricks within the DIVE framework. A new Virtual Environment system is required that has better knowledge of network performance, and that supports shared object manipulation across a network. The participant-study suggests that co-presence, the sense of being together with another person, was significantly and positively correlated with task performance.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123119460","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 briefly overview the MolDRIVE system, our visualization and computational steering environment for molecular dynamics real-time simulations, which is the platform for our particle steering implementation.Our study concentrates on visual feedback tools. We compare a basic virtual particle steering method with two other methods using a spring manipulator. The first just creates a visual feedback of a flexible connection between the user's interaction device and the steered particle, while the second technique creates a visual illusion of force feedback. The user can, through the spring manipulator, exert a force on the manipulated particle in the MD simulation. All presented particle steering tools are intuitive and easy to use.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130674350","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 technique has proven effective in desktop interfaces but the difficulty of working inside a VE remains because VE interfaces do not understand what the user is trying to do, only what the metaphor wants to do. To handle this problem, we investigated a lower-level approach in interface design of letting the user work as they wish and the interface adapting to the user's method of interaction. Two exploratory experiments were performed on the task of selection to learn how users want to work, with the results being that users do not know until guided by affordances and feedback. Discussed is the intelligent capturing and dealing with VE interface data in terms of Nuances that can represent the details of the interface.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124931858","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}
