In this paper we compare real-world pointing to pointing at virtual objects in a two-user scenario. In our study we investigated the following situation: One user points at an object while the second person has to guess the referenced object. Our results indicate that pointing at objects in a virtual world is much less precise than pointing in the real world even for a well calibrated stereoscopic two-user system. Pointing techniques like outlining an object or pointing from a distance produce more errors than the corresponding real-world techniques, but they are less error prone than interactions requiring to touch a virtual object. Our findings are a first step to qualify direct interaction techniques in a multi-user projection-based system.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124529818","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}

Each unit interacts asynchronously with its peers, leveraging their combined computational power to cooperatively estimate the poses of all of the projectors. In cases where the projection surface is static, our system is able to continuously refine all of the projector poses, even when they change simultaneously.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"32 9-10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132757306","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 present odors with a vivid sense of reality, we propose to use computational fluid dynamics (CFD) simulation in conjunction with the olfactory display system. In this demonstration, an odor is released with a movie clip using the olfactory display. A CFD solver is employed to calculate the turbulent airflow field in the given environment and diffusion/advection of odor molecules from their source. The olfactory display system generates an odor with the concentration determined by the calculated odor distribution. The user is assumed to be a small animal slowly walking through a virtual room, and experiences the spread of the odor in the room.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126606235","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 order to achieve this goal, an Image Based Lighting approach is proposed, where environment maps with different levels of glossiness are generated for each virtual object in the scene at every frame. Due to this, illumination effects, such as color bleeding and specular reflections, can be simulated for virtual objects in a consistent way, even under the presence of scene changes. A unifying sampling method for the spherical harmonics transformation pass is also used. It is independent of map format and does not need to apply different weights for each sample. The developed technique is combined with an extended version of Lafortune Spatial BRDF, featuring Fresnel effect and an innovative tangent rotation parameterization. The solution is evaluated in various Augmented Reality case studies, where other features like shadowing and lens effects are also exploited.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130186100","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 this experiment, we used the simulation method to investigate the effects of registration error on task performance for a generic task involving precise motor control for AR object manipulation.

This algorithm is well-suited to large environments in which many objects are not moving at once. We analyze and test implementations of sweep and prune that include subdivision, batch insertion and removal, and segmented interval lists. Our tests show these techniques provide higher performance than previous sweep and prune methods, and perform better than octrees in temporally coherent environments.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115029328","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}
