The CBWSN is self-configurable and re-configurable, thus capable of performing two dynamic operations: node-move-in and node-move-out. In this paper, we propose two efficient congregation techniques for Dynamic CBWSN. In order to facilitate the efficient congregation protocols we propose an improved cluster-based structure. In this structure, we first construct a communication highway, and then improve the cluster-based structure to facilitate efficient congregation protocols such that the nodes of the network can perform inter and intra cluster communications efficiently. We also study the time complexity of the protocols.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128017622","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 make an extended collaborative work space withoutrestriction of time and place, one possible way is adoptingmobile devices. In this paper, we propose a way to monitor andcontrol the table-top using mobile devices. To monitor thelarge-screen table-top with a mobile device, it is necessary toconvert image into low-resolution for the device. We adopt a\"Focus & context\" image generation method for tabletopcontrol, to convert relatively large screen images into smallerone for mobile display. With this method, users are able tohave their own point of view for tabletop-based collaborationand also to have extended work spaces by adopting remotecontrol. We prove the result by conducting several experiments.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130972661","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 also estimate the moving illuminant for changes of the scene illumination, and augment the virtual objects onto the real image with the proper shading and shadows.

However, content is increasingly being geo-coded and semantically labeled, making explicit connections between the physical world around us and the virtual world in cyberspace. Most augmented reality systems simulate a portion of the physical world, for the purposes of rendering a hybrid scene around the user. We have been experimenting with approaches to terra-scale, heterogeneous augmented reality mirror worlds, to unify these two worlds. Our focus has been on the authoring and user-experience, for example allowing ad-hoc transition between augmented and virtual reality interactions for multiple co-present users. This form of ubiquitous virtual reality raises several research questions involving the functional requirements, user affordances and relevant system architectures for these mirror worlds. In this paper, we describe our experiments with two mirror world systems and some lessons learned about the limitations of deploying these systems using massively multiplayer and dedicated game engine technologies.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115913856","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}

Our method combines both barcode detection and natural feature tracking methods to track a planar object efficiently on mobile devices. A planar target is detected by recognizing the barcode located near the target, and the target's keypoints are tracked in video sequences. We embed the information related to a planar object into the barcode, and the information is used to limit image regions to perform keypoint matching between consecutive frames. We show how to detect a barcode robustly and what information is embedded for efficient tracking. Our detection method runs at 30 fps on modern mobile devices, and it can be used for mobile augmented reality applications using planar targets.","PeriodicalId":339967,"journal":{"name":"2011 International Symposium on Ubiquitous Virtual Reality","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130040014","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}
