This paper describes the approaches that are being examined and the current status of the project. As a platform for the experiments, a prototype version of a multi-sensory theater has been implemented. The theater is equipped with devices that present wind and olfactory sensations. The sensation of wind is generated by both computer-controlled fans and air nozzles connected to a source of compressed air, and the olfactory sensation is presented by emitting odorants into the air. To facilitate the creation of content, a framework for editing multi-sensory information was constructed, in which all of the devices were connected to and controlled by a sequencer based on a MIDI interface.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116442987","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}

Seamless fusion and real-time interaction between virtual environment and real users or objects are two most important problems urgent to be solved for a MR system. In this paper an engine of virtual reality mixing environment E-VRME is proposed based on real-time modeling and interaction and three applications are demonstrated. The engine runs on our self-built hardware platform DreamWorld and has three modules. Graphics module is designed for VE rendering, modeling module for 3D reconstruction and V-R interaction module for collision detection and feedback. An octree-based visual hull modeling method is used for constructing the mesh models of all the users from their multi-view images. Then, marching cubes algorithm is applied for triangulation and texture mapping is carried out. E-VRME integrates virtual and real information into a seamless unit and it supports any kinds of real-time MR applications. Experimental results and three different application systems proved its usefulness and effectiveness.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129667546","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 paper presents two methods of computing walkthrough paths in a polygon with h holes and a total of n vertices, for 3D virtual worlds such as virtual museums and games. For any two points s and t, one method is presented to compute the shortest Voronoi skeleton path SVSP(s,t) in O(k + hlogh + logn) time, where k is the number of the Voronoi edges in SVSP(s,t) and O(k) ≤ O(n). An approximate shortest path from s to t can be computed in O(k + hlogh + logn) time based on SVSP(s,t). The other is to compute the shortest path SP(s,t) in O(m + hlog(n/h) + h2 logh) time, where m is the number of the edges in SP(s,t) and m ≤ n. They are based on a hierarchical Voronoi diagram presented in this paper, which can be constructed in time O(nlogn) with O(n) space in the preprocessing stage. This data structure also can be used to fast solve visibility information, collision detection and other problems in 3D virtual worlds. The methods are simpler and faster than other existed methods, with lower space.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115723609","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 our system each of the MUAVs is equipped with advanced network as well as different sensor technologies, which allow to capture images from low altitudes and to transfer those to a ground station, where the captured environment is reconstructed. At the ground station, the virtual 3D reconstruction is displayed in different virtual reality (VR) environments in which operators can not only explore the VE, but also interactively control the 3D reconstruction process. Therefore, virtual representations of the real MUAVs are visually integrated in the VE according to their real world position and orientation. The operator can manually steer these virtual MUAVs leading to corresponding movements of their real world counterparts. In this paper we introduce the AVIGLE project. In particular, we describe the 3D reconstruction process as well as the rendering of the large amount of data collected by the MUAVs. Furthermore, we outline the VR setup, and explain in detail how operators can interact with the virtual 3D reconstruction and the visual representation of the MUAVs.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131371950","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, few show practical experiences in Internet wide tele-immersion, especially in acceptable end-to-end delay. We present a framework for multi-party tele-immersion applications that allow remote collaborative 3D interactions. This framework performs real-time stereo modeling based on the bumblebee cameras. It provides an architecture that supports several tele-immersion nodes to communicate in groups. This paper addresses how to reconstruct, compress and establish the system. The system has been set up in China NGI. Preliminary experiment results show that it's possible to have the delay under 100ms with 320*240 depth map and 640*480 texture images. The framework is also expected to be further extended for interaction with full-body reconstruction.","PeriodicalId":197131,"journal":{"name":"2011 IEEE International Symposium on VR Innovation","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121875029","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 thickness of this system is below 1.0 mm and this system can generate 30.0 mm stroke. Furthermore, it can lift an object of 50 g at 30.0 mm and can withstand 100 g load at the top.
