Users can talk to each other, gesture and point into the virtual scenery as if it were real. As in reality, referring to objects by pointing, results often in a situation whereon objects are occluded from the other users' viewpoints. While in reality this problem can only be solved by adapting the viewing position, specialized individual views of the shared virtual scene enable various other solutions. As one such solution we propose show-through techniques to make sure that the objects one is pointing to can be seen by others. We analyzed the influence of such augmented viewing techniques on the spatial understanding of the scene, the rapidity of mutual information exchange as well as the social behavior of users. The results of our user study revealed that show-through techniques support spatial understanding on a similar level as walking around to achieve a non-occluded view of specified objects. However, advantages in terms of comfort, user acceptance and compliance to social protocols could be shown, which suggest that virtual reality techniques can in fact be better than 3D reality.","PeriodicalId":144717,"journal":{"name":"2010 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128159092","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}

Applications written for jReality will run unchanged on software and hardware platforms ranging from desktop machines with a single screen and stereo speakers to immersive virtual environments with motion tracking, multiple screens with 3D stereo projection, and multi-channel audio setups. In addition to euclidean geometry, jReality supports hyperbolic and elliptic geometry. jReality comes with a number of graphics rendering backends, ranging from pure software to hardware-accelerated to photorealistic. A distributed backend is available for cluster-based virtual environments. Audio backends range from a basic stereo renderer to a high-performance Ambisonics renderer for arbitrary 3D speaker configurations. jReality achieves device-independent user interaction through a layer of abstract input devices that are matched at runtime with available physical devices, so that a jReality application will work with keyboard and mouse in a desktop environment as well as with motion tracking in a virtual environment.","PeriodicalId":144717,"journal":{"name":"2010 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132243406","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}

Our method consists in modifying the motion of the virtual subjective camera while the user is really walking in an immersive virtual environment. The modification of the virtual viewpoint is a function of the variations in the height of the virtual ground. Three effects are proposed: (1) a straightforward modification of the camera's height, (2) a modification of the camera's navigation velocity, (3) a modification of the camera's orientation. They were tested in an immersive virtual reality setup in which the user is really walking. A Desktop configuration where the user is seated and controls input devices was also tested and compared to the real walking configuration. Experimental results show that our visual techniques are very efficient for the simulation of two canonical shapes: bumps and holes located on the ground. Interestingly, a strong ¿orientation-height illusion¿ is found, as changes in pitch viewing orientation produce perception of height changes (although camera's height remains strictly the same in this case). Our visual effects could be applied in various virtual reality applications such as urban or architectural project reviews or training, as well as in videogames, in order to provide the sensation of walking on uneven grounds.","PeriodicalId":144717,"journal":{"name":"2010 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"292 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116528622","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}
