A large number of techniques exist to support a natural user interface (NUI) by detecting the user's hand posture in RGB+D (depth) data. Depending on a given interaction scenario, each technique has its advantages and disadvantages. To evaluate the performance of the various techniques on a mobile device, we conducted a systematic study by comparing the accuracy of five common posture recognition approaches with varying illumination and background. To be able to perform this study, we developed a powerful software framework that is capable of processing and fusing RGB and depth data directly on a handheld device. Overall results reveal best recognition rate of posture detection for combined RGB+D data at the expense of update rate. Finally, to support users in choosing the appropriate technique for their specific mobile interaction task, we derived guidelines based on our study.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"1 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":"129586872","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, a system capable of collecting, perceiving and interpreting unconscious behavior can provide rich contextual information for an interactive system. One possible application for such a system is in the exploration of complex data through immersion, where massive amounts of data are generated every day both by humans and computer processes that digitize information at different scales and resolutions thus exceeding our processing capacity. We need tools that accelerate our understanding and generation of hypotheses over the datasets, guide our searches and prevent data overload. We describe XIM-engine, a bio-inspired software framework designed to capture and analyze multi-modal human behavior in an immersive environment. The framework allows performing studies that can advance our understanding on the use of conscious and unconscious reactions in interactive systems.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"225 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":"134344298","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}

With aging, the human skin becomes thinner and flattens with dermal papillae being less pronounced. The epidermis becomes fine-drawn and the dermal network deteriorates with decades. The three-dimensional structure of elastic network and the hyaluronic acid distribution are so complex, rich and dense that the conventional observation ways can only provide partial view of these components. Objective: The aim of this study was to demonstrate the morphological differences between two abdominal skin samples coming from young and aged donors based on elastic fibers organization and hyaluronic acid distribution. Methods: The SkinExplorer™ platform performs immersive and interactive exploration with virtual reality applications. Results: 2mm3 of histological data were obtained from 40 serial histological sections. Two three-dimensional numerical models from respectively young and aged skin biopsies were reconstructed. The observations were realized on the epidermis and dermal elastic fibers with the SkinExplorer™ platform and virtual reality (VR) applications. For hyaluronic acid repartition, two smaller models were reconstructed to see their richness and density by the same platform and VR tools. Conclusion: These results suggest that Virtual Reality applications can be a good tool for the observation of aging process with its assessing and understanding. Moreover, this tool of exploration offers new way of micro-anatomical research.","PeriodicalId":128331,"journal":{"name":"Proceedings of the 2014 Virtual Reality International Conference","volume":"53 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":"115828210","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}
