We first present a way of creating object-aligned annotations with very little user effort. Second, we describe techniques to segment and pop-up foreground objects. Finally, we introduce a method using the laser range finder to incrementally build 3D panoramas from a fixed observerpsilas location. To build a 3D panorama semi-automatically, we track the systempsilas orientation and use the sparse range data acquired as the user looks around in conjunction with real-time image processing to construct geometry around the userpsilas position. Using full 3D panoramic geometry, it is possible for new virtual objects to be placed in the scene with proper lighting and occlusion by real world objects, which increases the expressivity of the AR experience.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"107 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132477134","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}

It has good positioning accuracy, low drift and jitter, and low computation requirement. It eliminates the resolution of integer ambiguities. The position from an initial point is tracked by accumulating the displacement in each time step, which is determined using Differential Single Difference. Preliminary results using low cost GPS receivers show that the position error is 10 cm, and the drift is 0.001 ms-1, which can be compensated using linear models. Stable and accurate augmentations in outdoor scenes are demonstrated.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133266510","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}

Categorizing error by types that are often used as specifications, we hoped to derive some insight into the ability of users to tolerate noise, latency, and orientation error. We used measurements from actual systems to derive the parameter settings. We expected all three errors to influence userspsila ability to perform the task correctly and the precision with which they performed the task. We found that high latency had a negative impact on both performance and response time. While noise consistently interacted with the other variables, and orientation error increased user error, the differences between ldquohighrdquo and ldquolowrdquo amounts were smaller than we expected. Results of userspsila subjective rankings of these three categories of error were surprisingly mixed. Users believed noise was the most detrimental, though statistical analysis of performance refuted this belief. We interpret the results and draw insights for system design.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114739065","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}

A sparse set of 3D cone fiducials are utilized for scalable indoor/outdoor tracking, as opposed to traditional planar patterns. The cones are easy to segment and have a large working volume which makes them more suitable for many applications. The pose estimation system receives measurements from the camera and IMU at 30 Hz and 100 Hz respectively. With a dual-core workstation, all measurements can be processed in real-time to update the pose of virtual graphics within the AR display.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121965234","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 results show that visual cue-based collaborative navigation techniques are significantly more efficient than an audio-only technique.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121526096","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}

Wireless tracking of the physical prototype is achieved in three different ways by attaching to it a 'Speck', a tracker and Nintendo Wii Remote and it provides continuous tangible interaction.

While many applications need to consider more than one object in practice, the existing methods for single object tracking do not scale well with the number of objects, and a proper way to deal with several objects is required. Our method combines object detection and tracking: Frame-to-frame tracking is less computationally demanding but is prone to fail, while detection is more robust but slower. We show how to combine them to take the advantages of the two approaches, and demonstrate our method on several real sequences.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131853833","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}

Redlining is the term used for manually annotating either printed paper maps or a 2D geographic information system on a notebook computer taken to the field. Either of these approaches requires finding the physical location to be annotated on the physical or digital map. In this paper, we describe a mobile Augmented Reality (AR) system capable of supporting virtual redlining. The AR visualization delivered by the system is constructed from data directly extracted from a GIS used in day-to-day production by utility companies. We also report on encouraging trials and interviews performed with professional field workers from the utility sector.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123948936","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}
