That type of animation is most often the result of a physics-based simulation and has a high computational cost. The fabric model consists of a triangular mesh and uses a spring-mass-damper system to compute the forces among the particles, which are located at the mesh's vertices. However, this work's main objective is to study the dynamic behavior of cloth, using a remeshing procedure in order to adapt the mesh.","PeriodicalId":189272,"journal":{"name":"2013 XV Symposium on Virtual and Augmented Reality","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122519604","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}

However, even if they are very sensitive and precise, inertial sensors work with incremental information, easily introducing errors in the system. The most important is that head tracking both in head mounted displays (HMD) and other systems based on inertial sensors suffer from drifting. In this paper we present some important limitations that still prevent the wide use of sensors like a single Kinect for full body tracking in immersive VR systems. Inevitably, to compensate for the drifting, the user moves away from the suitable pose in front of the Kinect, being a restrictive limitation for this kind of tracking. In this work we introduce a software solution for this problem and evaluate it experimentally. Results show that our comfortable pose function is effective on eliminating drifting. The efficiency and accuracy of this method makes it suitable for a number of applications in immersive VR.","PeriodicalId":189272,"journal":{"name":"2013 XV Symposium on Virtual and Augmented Reality","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128841905","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 training needs to mimic risk scenarios, where the individuals may exercise proper procedures. It is also necessary that such individuals get to know the surrounding of their specific work place, so that they can be able to use proper escape routes, even under stress. Virtual Reality, and the related Virtual Environments, have been shown to be quite effective in training applications. Good examples range from Flight Simulators to more recent efforts in various training scenarios. This work introduces a low-cost offshore oil platform training simulation, which allows a user to exploit the synthetic environment through free walking in the environment. The system uses a Nintendo Wii Fit Plus Balance Board to allow a user to walk in the system using natural leg movements. The 3D models of the offshore oil platform are presented in a low-cost CAVE setup in a Collaborative Virtual Environments, which includes avatars that represent other users of the system, both bots and those representing other real users.","PeriodicalId":189272,"journal":{"name":"2013 XV Symposium on Virtual and Augmented Reality","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126903723","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}

Furthermore, the Requirements Engineering (RE) has a key role in the development of VR systems, because the requirements of these systems are imposed directly by human senses and abstracted by the ability of the developers to represent the physical and kinematic models of these environments. The aim of this paper is to present the results of a Systematic Literature Review to consolidate existing evidence regarding the use of RE for VR systems and VR contributions to the RE process. We have analyzed 12 primary studies published between 1998 and 2011. The results indicate mainly the deficiency of studies that show the use of the RE process for VR systems, because it is necessary that this process occur in accordance with the technological peculiarities of VR systems.","PeriodicalId":189272,"journal":{"name":"2013 XV Symposium on Virtual and Augmented Reality","volume":"336 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124725824","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}
