The system combines marker-less face and body tracking to animate the individual avatars seen in a stereoscopic display with a correct perspective projection. The display dimensions match typical dimensions of a real physical mirror and the animated avatars are rendered based on a geometrically correct reflection as expected from a real mirror including correct body and face animations. The first evaluation of the system reveals the high acceptance of the setup as well as a convincing illusion of a real mirror with different types of avatars.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116180177","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}

Large screens such as wall-sized displays are now equipped with multi-touch capabilities. Multi-touch wall-sized displays will become widespread in a near future in various places such as public places or meeting rooms. These new devices are an interesting opportunity to interact with 3D virtual environments: the large display surface offers a good immersion, while the multi-touch capabilities could make interaction with 3D content accessible to the general public. In this paper, we aim to explore touch-based 3D interaction in the situation where users are immersed in a 3D virtual environment and move in front of a vertical wall-sized display. We design In(SITE), a bimanual touch-based technique combined with object teleportation features which enables users to interact on a large wall-sized display. This technique is compared with a standard 3D interaction technique for performing 6 degrees of freedom manipulation tasks on a wall-sized display. The results of two controlled experiments show that participants can reach the same level of performance for completion time and a better precision for fine adjustments of object position with the In(SITE) technique. They also suggest that combining object teleportation with both techniques improves translations in terms of ease of use, fatigue, and user preference.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114828686","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, it is difficult to accurately place an object in immersive virtual environments using mid-air gestures that mimic interactions in the physical world, although being a direct and natural approach. Previous research studied mouse and touch based interfaces concluding that separation of degrees-of-freedom (DOF) led to improved results. In this paper, we present the first user evaluation to assess the impact of explicit 6 DOF separation in mid-air manipulation tasks. We implemented a technique based on familiar virtual widgets that allow single DOF control, and compared it against a direct approach and PRISM, which dynamically adjusts the ratio between hand and object motions. Our results suggest that full DOF separation benefits precision in spatial manipulations, at the cost of additional time for complex tasks. From our results we draw guidelines for 3D object manipulation in mid-air.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123526816","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 is tailored for the application in real-time interactive systems, specifically for Virtual Reality, and solves three problems commonly encountered in this context: (1) The lexical information is defined on and grounded in a common knowledge representation layer (KRL) based on OWL. The KRL describes application objects and possible system functions in one place and avoids error-prone redundant data management. (2) The KRL is tightly integrated into the simulator platform using a semantically enriched object model that is auto-generated from the KRL and thus fosters high performance access. (3) A well-defined interface provides application wide access to semantic application state information in general and the lexical information in specific, which greatly contributes to decoupling, maintainability, and reusability.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"212 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121200327","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 particular, in immersive stereoscopic systems, e.g. when performing zoom-in and zoom-out operations, the navigation speed and the stereoscopic rendering parameters have to be adjusted accordingly. Although this adjustment can be done manually by the user, it can be complex, tedious and strongly depends on the virtual environment. In this work we propose a new multi-scale navigation technique named GiAnt (GIant/ANT) which automatically and seamlessly adjusts the navigation speed and the scale factor of the virtual environment based on the user's perceived navigation speed. The adjustment ensures an almost-constant perceived navigation speed while avoiding diplopia effects or diminished depth perception due to improper stereoscopic rendering configurations. The results from the conducted user evaluation shows that GiAnt is an efficient multi-scale navigation which minimizes the changes of the scale factor of the virtual environment compared to state-of-the-art multi-scale navigation techniques.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128206829","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 approach computes a set of collision-free feasible movement directions for each agent. The movement directions of the agent are determined according to a radial view of the agent in the local region. Subsequently, the direction with the least effort is selected for moving the agent. To efficiently compute feasible movement directions for each agent, we discretize the movement direction field of the agent and use a bit string to estimate the set of movement directions. Each bit of the bit string represents a span of movement directions. The proposed approach enables the agents to move around simple objects without using expensive global search techniques. Experimental results show that our approach can simulate agents that can alleviate the collision problem. The agents can move to their destinations efficiently.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126030709","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}
