Unlike the virtual reality(VR), the augmented reality (AR) is an environment containing virtual and real objects simultaneously. However, the difference in motion between the virtual and real objects is obvious, which makes it hard for AR to be realistic and attractive. To reduce this gap, we propose to apply physical attributes to each virtual object, which can be done by using a physics engine, a software library containing functions related with physics. For this purpose, an ODE (open dynamics engine) library is used. However, the direct use of the library in the AR environment poses a lot of problems. Most of all, the coordination of the coordinate systems between OSG (OpenSceneGraph) and ODE must be taken care of. Next the positions of markers are also needed to be considered. In this paper, such problems are addressed and solutions to them are discussed.","PeriodicalId":378529,"journal":{"name":"2008 International Symposium on Ubiquitous Virtual Reality","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121493649","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, the user-interface to these applications is generally still limited to the basic phone keypad which detracts from the sophisticated experience 3-D worlds can provide. In this paper we present a solution to this problem which utilizes the accelerometers on mobile phones to provide 3-D motion-controlled navigation through networked 3-D environments. This mechanism not only eliminates the use of buttons on the phone for control but also bridges the physical world to the virtual one to maintain optimum user experience.","PeriodicalId":378529,"journal":{"name":"2008 International Symposium on Ubiquitous Virtual Reality","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121592677","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}

Unfortunately, on-the-go users are impaired by their mobility and often find desktop-style Windows Icon Menu and Pointer (WIMP) interfaces difficult, if not impossible, to use while performing their primary task (walking, having a conversation, fixing a copier, etc.). Instead of having interfaces that consume attention, why can't mobile devices be like a well-trained English butler who needs so little direction to satisfy his client's needs that he seems to read minds? Inspired by this concept, we will demonstrate mobile interfaces that provide valuable services while requiring little effort by the user.","PeriodicalId":378529,"journal":{"name":"2008 International Symposium on Ubiquitous Virtual Reality","volume":"4 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131002357","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}

We propose an AR system architecture that works with a context-awareness framework. In the system, both the preliminary and the final context is provided to the process that needs the context. We provide two scenarios that exploit the context in AR applications in the low-level processing and show implementation results with the proposed system. In the first scenario, we adopt a light sensor to enhance the marker detection performance under the varying lighting condition. In the second scenario, we exploit the context in the marker recognition stage where a single color marker is recognized as several different sub-markers based on the context. By adopting the context in the low-level processing, it is possible to address the problems that are hard to be solved by the computer vision techniques only.","PeriodicalId":378529,"journal":{"name":"2008 International Symposium on Ubiquitous Virtual Reality","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132958840","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}

Designers or CEOs may perceive the size and appearance of the product by touching the automatically constructed physical objects produced through rapid prototyping. However, it is usually impossible to change its color, texture, and user interface. In this paper, we introduce 'Augmented Reality based Re-formable Mock-up', which enables interactive changes of shapes of products as well as colors, textures, and user interfaces. The shapes of the physical objects are re-formable by assembling different parts to the main body of the mock-up. Augmented Reality technologies were used to alter the appearance of the mock-up by rendering the 3D models, colors, and interfaces accordingly. The re-assembled mock-up was detected by comparing the edges of the mock-up with those of candidate 3D models. Skin detection was used in order to render the hand region on the top of rendered virtual object. Fingertip tracking algorithm was also implemented so that the users may manipulate the design product using their fingertips. Developed AR-based re-formable mock-up is expected to be used for realistic design evaluation and CEO presentations.","PeriodicalId":378529,"journal":{"name":"2008 International Symposium on Ubiquitous Virtual Reality","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132591051","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}
