We achieve interactive frame rates of up to 20 Hz for natural feature tracking from textured planar targets on current-generation phones. We use an approach based on heavily modified state-of-the-art feature descriptors, namely SIFT and Ferns. While SIFT is known to be a strong, but computationally expensive feature descriptor, Ferns classification is fast, but requires large amounts of memory. This renders both original designs unsuitable for mobile phones. We give detailed descriptions on how we modified both approaches to make them suitable for mobile phones. We present evaluations on robustness and performance on various devices and finally discuss their appropriateness for augmented reality applications.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"24 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132881101","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}

Through mixed reality (MR), collocated AAR allows users to review past training experiences in situ with the userpsilas current, real-world experience. MR enables a user-controlled egocentric viewpoint, a visual overlay of virtual information, and playback of recorded training experiences collocated with the userpsilas current experience. Collocated AAR presents novel challenges for MR, such as collocating time, interactions, and visualizations of previous and current experiences. We created a collocated AAR system for anesthesia education, the augmented anesthesia machine visualization and interactive debriefing system (AAMVID). The system was evaluated in two studies by students (n=19) and educators (n=3). The results demonstrate how collocated AAR systems such as AAMVID can: (1) effectively direct student attention and interaction during AAR and (2) provide novel visualizations of aggregate student performance and insight into student understanding for educators.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"408 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":"124332209","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 contrast to other model building methods that are either off-line and/or automated but computationally intensive, the aim here is to have a system that has low computational requirements and that enables the user to define what is relevant (and what is not) at the time the model is being built. OutlinAR hardware is also developed which simply consists of the combination of a camera with a wide field of view lens and a wheeled computer mouse.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"20 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":"123851598","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 major problem in this context consists in the poor proposal distribution of the camera pose particles obtained from the weak motion model of a camera moved freely in 3D space. While the FastSLAM 2.0 extension is one possibility to improve the proposal distribution, this paper addresses the question of how to use measurements from low-cost inertial sensors (gyroscopes and accelerometers) to compensate for the missing control information. However, the integration of inertial data requires the additional estimation of sensor biases, velocities and potentially accelerations, resulting in a state dimension, which is not manageable by a standard PF. Therefore, the contribution of this paper consists in developing a real-time capable sensor fusion strategy based upon the marginalised particle filter (MPF) framework. The performance of the proposed strategy is evaluated in combination with a marker-based tracking system and results from a comparison with previous visual-inertial fusion strategies based upon the extended Kalman filter (EKF), the standard PF and the MPF are presented.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"29 4 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":"125861657","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}

However, perfect registration is not always necessary for users to understand the intent of an augmentation. This paper describes the results of an experiment to evaluate the effects of graphical context in a Lego block placement task when the graphics are located outside of the task area. Four conditions were compared: fully registered AR; non-registered AR; a heads-up display (HUD) with the graphics always visible in the field of view; and a HUD with the graphics not always visible in the field of view. The results of this experiment indicated that registered AR outperforms both non-registered AR and graphics displayed on a HUD. The results also indicated that non-registered AR does not offer any significant performance advantages over a HUD, but is rated as less intrusive and can keep non-registered graphics from cluttering the task space.","PeriodicalId":168134,"journal":{"name":"2008 7th IEEE/ACM International Symposium on Mixed and Augmented Reality","volume":"55 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":"129821751","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}
