The influence of form variables such as screen size has been mainly investigated on the sense of physical presence (presence as transportation) in virtual environment and in television area, but less attention has been paid to how these factors can influence the sense of co-presence in videoconferencing. In addition, preferred viewing distance is well known to be a key parameter in order to convey a sense of presence and enjoyment when people watch television, but there is currently no data regarding preferred viewing distance in videoconferencing. This paper presents a user study which explores the influence of screen size on the participant's sense of co-presence and on their preferred viewing distance. The main results of this study revealed that users preferred to get closer to the screen when they communicated in videoconferencing than when they watched TV program. Our study suggests that screen size has an effect on the preferred viewing distance and on the participant's sense of co-presence, with higher scores of co-presence with larger screen.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122109904","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}

Numerical simulations have become crucial during the product development process (PDP) for predicting different properties of new products as well as the simulation of various kinds of natural phenomena. \"What-if-scenarios\" and conceptual changes to either the boundary or the domain are time consuming and cost intensive. Most of the time, engineers are interested in a deeper understanding of local quantities rather than being exposed to an iterative re-simulation of the overall domain. New techniques for automatic and interactive processes are then challenged by the cardinality and structural complexity of the CAE domain. This paper introduces a new interactive technique that automatically reduces the analysis space, and allows engineers to enhance the resolution of local problems without a need for recalculating the global problem. The technique, integrated into a VR based front end, achieves faster reanalysis cycles compared with traditional COTS tool chains and engineering workflows.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130236384","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 addition, surgery robots are highly expensive to both acquire and maintain --- thereby entailing the need for efficient training. When training with the robot, the communication between the trainer and the trainee is limited, since the trainee often cannot see the trainer. To overcome this issue, this paper proposes an Augmented Reality (AR) system where the trainer is controlling two virtual robotic arms. These arms are virtually superimposed on the video feed to the trainee, and can therefore be used to demonstrate and perform various tasks for the trainee. Furthermore, the trainer is presented with a 3D image through a stereoscopic display. Because of the added depth perception, this enables the trainer to better guide and help the trainee. A prototype has been developed using low-cost materials and the system has been evaluated by surgeons at Aalborg University Hospital. User feedback indicated that a 3D display for the trainer is very useful as it enables the trainer to better monitor the procedure, and thereby enhances the training experience. The virtual overlay was also found to work as a good and illustrative approach for enhanced communication. However, the delay of the prototype made it difficult to use for actual training.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123401319","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 sheer enormity of big data makes the task of extracting semantic associations out of complex networks more complicated. Stemming this \"data deluge\" calls for novel unprecedented technologies. In this work, we engineered a system that enhances a user's understanding of large datasets through embodied navigation and natural gestures. This system constitutes an immersive virtual reality environment called the \"eXperience Induction Machine\" (XIM). One of the applications that we tested using our system is the exploration of the human connectome: the network of nodes and connections that underlie the anatomical architecture of the human brain. As a comparative validation of our technology, we then exposed participants to a connectome dataset using both our system and a state-of-the-art software for visualization and analysis of the same network. We systematically measured participants' understanding and visual memory of the connectomic structure. Our results showed that participants retained more information about the structure of the network when using our system. Overall, our system constitutes a novel approach in the exploration and understanding of large complex networks.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122317612","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}

No information except that seen from a single viewpoint is included in the rendered image, although 3D models are used to construct a 3D scene. Even when rendering for binocular stereopsis is performed, the viewpoints are only two. This characteristic is a limitation of the conventional 3DCG expression. In this study, we propose a new approach to 3DCG art expression. Our system uses integral photography (IP) consisting of a tablet device and a fly's eye lens. Stereoscopy is possible without the need for the user to wear special glasses even if the device is placed in any orientation because parallax is caused not only in a horizontal position but also in all directions in IP. A ready-made fly's eye lens can be combined with various tablet devices that have different screen resolutions because the extended fractional view method is used. The device is so small and lightweight that users can appreciate 3D arts at any time and place. Notably, IP can reproduce such glittering effects because each minute convex lens of the IP display emits light in different directions. We produced a 3DCG artwork, called \"Frozen Time,\" that fully employs the characteristics of our technology in motifs of \"floating ice,\" \"crystallized fossils,\" and an \"opal flower.\"","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125753153","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}
