We code the conversational errors made by the VH.

We applied this method to a set of previously collected interactions between medical students and VH patients and present preliminary results. The error metrics do not correlate with traditional measures of the quality of a virtual experience, e.g. presence and copresence questionnaires. The error metrics were significantly correlated with scores on the Maastricht Assessment of Simulated Patients (MaSP), a scenario-appropriate measure of simulation quality, suggesting further investigation is warranted.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129032000","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}

This introduced the need to port many 3D desktop visualization applications to VR. Porting application GUIs can be a problem since original GUIs are 2D by nature and using them directly can obscure a large area of 3D viewport and spoil the immersive experience. On the other hand, rewriting a 3D GUI can be a time consuming and tedious task. In this work, we introduce a technique to embed 2D GUIs into 3D Virtual Environments (VE). Our approach uses existing 2D GUIs that can be immersed into the VE allowing rapid GUI development for VR applications. It can also be used for porting 3D desktop applications without rewriting the GUI code. Further, it enables embedding many window-based desktop applications into the VE, creating rich VEs where users can work with multiple applications simultaneously.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124736639","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 contrast to previous redirection techniques, this approach, based on a dynamic environment model, does not introduce any visual-vestibular conflicts from manipulating the mapping between physical and virtual motions, nor does it require breaking presence to stop and explicitly reorient the user. We conducted two user studies to evaluate the effectiveness of the change blindness illusion when exploring a virtual environment that was an order of magnitude larger than the physical walking space. Despite the dynamically changing environment, participants were able to draw coherent sketch maps of the environment structure, and pointing task results indicated that they were able to maintain their spatial orientation within the virtual world. Only one out of 77 participants across both both studies definitively noticed that a scene change had occurred, suggesting that change blindness redirection provides a remarkably compelling illusion. Secondary findings revealed that a wide field-of-view increases pointing accuracy and that experienced gamers reported greater sense of presence than those with little or no experience with 3D video games.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"785 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117032207","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}

We developed an olfactory feedback system to maintain user's concentration effectively based on biological information. The system presumes the level of user's concentration based on an electrocardiogram analysis. The analysis is carried out using variance of R-R intervals and frequency spectra. According to the presumed concentration level, the system presents an odor with an awakening effect to maintain user's concentration. We performed experiments in which subjects did simple tasks with this system, changing the method of controlling odor emissions. We compared the results of each method and evaluated the effectiveness of our olfactory feedback system and the methods of controlling odor emissions. The comparison of the results showed that presenting an odor when a user loses his/her concentration is effective to decrease errors of addition tasks.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114606966","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}

At the same time, when humans sense the hardness of real objects, it is known that their perception is influenced not only by tactile information but also by visual information. In this paper, we studied the psychophysical influence on the sense of hardness by using a real object that has a CGI superimposed on it. In this experiment, we deform in an extreme way the CGI animation on the real object, while the subject pushes the real object using his/her finger. The results of the experiments found that human subjects sensed different hardnesses by emphasizing the dent deformation of the CGI animation.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129080530","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}
