In this paper, we focus on development of an olfactory display using cross modality which can represent more patterns of scents than the patterns of scents prepared. Due to cross modal effect between vision and olfaction, human tends to feel not olfactory but visual stimulation as scents. First, we asked subjects to smell various aroma chemicals and evaluate their similarity. Based on the data of similarity among aromas, we built a map of smell distance. Next, we selected a few aroma chemicals from the smell distance map and implemented a visual and olfactory display. Then we conducted an assessment experiment of the display. We presented various pictures and the selected aroma chemicals to subjects and asked them what kind of scent they smelled like. In this experiment, we succeed in giving subjects feeling more patterns of scents than the number of selected aroma chemicals. Also, we succeed in making not olfactory stimulation by aroma chemicals but visual stimulation by pictures as scents. In particular, we find that the visual effect on olfactory sensation is more strong when the distance between the picture and the aroma chemicals is close than when the distance is far.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"37 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":"122791041","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}

To address the problem of motivation, we have developed Astrojumper, a stereoscopic virtual reality exergame which was designed to fit the needs of children with autism. During the game, virtual space-themed objects fly forward toward the user who must use their own physical movements to avoid collisions. Preliminary playtesting of Astrojumper on neuro-typical participants has been positive, and we plan to run an extensive evaluation assessing the psychological and physiological effects of this system on children with and without autism.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"25 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":"123064999","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 this paper, visual display of the simulator is improved in streoscopic. Then the training effectiveness has been evaluated based on difference between operation force by veterans and that by beginners. The result shows the developed simulator is effective, and the teaching function of the simulator contributes to training effect, whereas the stereo vision without the teaching function doesn't contribute so much.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"13 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":"131453995","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}

Using EAT, therapy patients have improved both physically and psychologically (e.g., demonstrating increased attention, motivation, and communication skills). There are still many open questions regarding this therapy and the reasons for its success. Many of these questions have remained unanswered due in large part to the uncontrolled nature of EAT. The Virtual Equine Assisted Therapy (VEAT) Project integrates a robotic platform with virtual reality technologies to provide a safe, controlled environment through which various aspects of EAT can be isolated and studied. The system incorporates realistic equine motions with visual, auditory, olfactory, and somatosensory stimuli to provide highly immersive experiences to patients.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"07 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":"116136721","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 purpose of this article was to evaluate the perception of affordances in virtual environments (VE). In order to test this perception, we considered the affordances for standing on a virtual slanted surface. The participants were asked to judge whether a virtual slanted surface supported upright stance. The perception was investigated by manipulating the texture of the slanted surface (Wooden texture vs. Ice texture). Results showed an effect of the texture: the perceptual boundary (or critical angle) with the Ice texture was significantly lower than with the Wooden texture. These results reveal that perception of affordances for standing on a slanted surface in virtual reality is possible and comparable to previous studies conducted in real environments.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"70 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":"115143928","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}

Computer vision systems use primarily image data to interpret the surrounding world, e.g to detect, classify and track objects. The performance of mobile computer vision systems acting in unknown environments is inherently difficult to evaluate since, often, obtaining ground truth data is problematic. The proposed novel framework exploits the possibility to add virtual agents into a real data sequence collected in an unknown environment, thus making it possible to efficiently create augmented data sequences, including ground truth, to be used for performance evaluation. Varying the content in the data sequence by adding different virtual agents is straightforward, making the proposed framework very flexible. The method has been implemented and tested on a pedestrian detection system used for automotive collision avoidance. Preliminary results show that the method has potential to replace and complement physical testing, for instance by creating collision scenarios, which are difficult to test in reality.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"24 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":"114062938","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}

Interactive 3D lenses, often called volumetric lenses, provide users with alternative views of datasets within spatially bounded regions of interest (focus) while maintaining the surrounding overview (context). In contrast to previous multi-pass rendering work, we discuss the strengths, limitations, and performance cost of a single-pass technique. For a substantial range of effects, it supports several interactive composable lenses at interactive frame rates without performance loss during increasing lens intersections or manipulations. Other cases, for which this performance cannot be achieved, are also discussed. Finally, we illustrate possible applications of our lens system, especially new Time Warp lenses for exploring time-varying datasets in interactive VR.","PeriodicalId":151060,"journal":{"name":"2010 IEEE Virtual Reality Conference (VR)","volume":"4 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":"122888887","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}
