Our system is based on the projection and detection of 3D optical tags. We use an infrared (IR) projector to project temporally-coded (blinking) dots onto selected points in a scene. These tags are invisible to the human eye, but appear as clearly visible time-varying codes to an IR photosensor. As a proof of concept, we have built a prototype camera system (consisting of co-located visible and IR sensors) to simultaneously capture visible and IR images. When a user takes an image of a tagged scene using such a camera system, all the scene tags that are visible from the system's viewpoint are detected. In addition, tags that lie in the field of view but are occluded, and ones that lie just outside the field of view, are also automatically generated for the image. Associated with each tagged pixel is its 3D location and the identity of the object that the tag falls on. Our system can interface with conventional image recognition methods for efficient scene authoring, enabling objects in an image to be robustly identified using cheap cameras, minimal computations, and no domain knowledge. We demonstrate several applications of our system, including, photo-browsing, e-commerce, augmented reality, and objection localization.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130297894","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 a virtual seating buck, users wear a head-mounted display (HMD) which overlays a virtual car interior on a physical seating buck. We have developed a two-user virtual seating buck system, which allows two users to take the role of the driver and co-driver respectively. Both users wear tracked head-mounted displays and see the virtual car interior from the respective view points enabling them to properly interact with the interface elements of a car. We use this system for the development, test and evaluation of novel human-machine interface concepts for future car models. We provide each user with an avatar, since the two co-located users need to see each others' actions. Our evaluation of different head and hand models for representing the two users indicate that the user representations and motions should be as realistic as possible even though the focus is on testing interface elements operated by the users' fingers. The participants of our study also expressed that they clearly prefer the two-user seating buck over a single-user system since it directly supports the face-to-face discussions of features and problems of a newly developed interface.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116674063","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}

Steed","doi":"10.1109/VR.2008.4480759","DOIUrl":"https://doi.org/10.1109/VR.2008.4480759","url":null,"abstract":"In collaborative virtual environments, the visual representation of avatars has been shown to be an important determinant of participant behaviour and response. We explored the influence of varying conditions of eye-representation in our high-fidelity avatar by measuring how accurately people can identify the avatar's point-of- regard (direction of gaze), together with subjective authenticity assessments of the avatar's behaviour and visual representation. The first of two variables investigated was socket-deformation, which is to say that our avatar's eyelids, eyebrows and surrounding areas morphed realistically depending on eye-rotation. The second was vergence of our avatar's eyes to the exact point-of-regard. Our results suggest that the two variables significantly influence the accuracy of point-of-regard identification. This accuracy is highly dependent on the combination of viewing-angle and the point-of-regard itself. We found that socket-deformation in particular has a highly positive impact on the perceived authenticity of our avatar's overall appearance, and when judging just the eyes. However, despite favourable subjective ratings, overall performance during the point-of-regard identification task was actually worse with the highest quality avatar. This provides more evidence that as we move forward to using higher fidelity avatars, there will be a tradeoff between supporting realism of representation and supporting the actual communicative task.","PeriodicalId":173744,"journal":{"name":"2008 IEEE Virtual Reality Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126084484","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}
