Previous work shows that the addition of haptic feedback cues improves performance on certain 3D tasks. However, we believe this is not true for all situations. Depending on the difficulty of the task, we suggest that we should expect differences in the ballistic movement of our hands when presented with different types of haptic force-feedback conditions. We investigated how hard, soft and no haptic force-feedback responses, experienced when in contact with the surface of an object, affected user performance on a task involving selection of multiple targets. To do this, we implemented a natural egocentric selection interaction technique by integrating a two-handed large-scale force-feedback device in to a CAVETM-like IVE system. With this, we performed a user study where we show that participants perform selection tasks best when interacting with targets that exert soft haptic force-feedback cues. For targets that have hard and no force-feedback properties, we highlight certain associated hand movement that participants make under these conditions, that we hypothesise reduce their performance.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"68 2 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":"128723394","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 discusses approaches for supporting copresent head-tracked users in an immersive projection environment, such as the CAVETM, without relying on additional projection and frame-multiplexing technology. The primary technique presented here is called Image Blending and consists of rendering independent views for each head-tracked user to an off-screen buffer and blending the images into a final composite view using view-vector incidence angles as weighting factors. Additionally, users whose view-vectors intersect a projection screen at similar locations are grouped into a view-cluster. Clustered user views are rendered from the average head position and orientation of all users in that cluster. The clustering approach minimizes users' exposure to undesirable display artifacts such as inverted stereo pairs and nonlinear object projections by distributing projection error over all tracked viewers. These techniques have the added advantage that they can be easily integrated into existing systems with minimally increased hardware and software requirements. We compare Image Blending and View Clustering with previously published techniques and discuss possible implementation optimizations and their tradeoffs.","PeriodicalId":433266,"journal":{"name":"2009 IEEE Virtual Reality Conference","volume":"5 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":"121370642","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}
