Except for the six-sided CAVE systems, the missing back wall(s) of a CAVE system can be a confounding factor when virtual and physical navigation interaction techniques are compared, regarding the viewpoint rotation. We introduce a virtual black wall as a way to avoid a possible confounding factor in comparative studies. Based on our pilot study, we found that the virtual black wall can provide the comparable experimental condition for the two types of navigation interaction techniques and that the wall can play a dual role as an obstacle and a landmark during navigation. These findings provide a stepping stone for further investigation of the virtual black wall.","PeriodicalId":220761,"journal":{"name":"2012 IEEE Virtual Reality Workshops (VRW)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126224389","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 hypothesize that the inclusion of virtual characters within these environments can improve an observer's ability to judge distances and achieve accurate spatial understanding. We have conducted an empirical study using a desktop display of a small scale environment to evaluate the validity of this concept. We investigated whether the presence and quantity of virtual human characters, as well as the naturalness of their locomotion animations, could improve egocentric and exocentric distance estimations. Preliminary results suggest that static or properly animated characters could improve exocentric estimations, and properly animated characters could reduce egocentric distance compression errors.","PeriodicalId":220761,"journal":{"name":"2012 IEEE Virtual Reality Workshops (VRW)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114521804","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}

Users can be immersed within challenging combat contexts and interact with virtual characters within these episodes as part of an experiential learning approach. Such approaches, often referred to as Stress Inoculation Training, have been found to reduce the neuroendocrine response, increase coping competence and reduce cortisol response. STRIVE is currently developing three combat modules with a narrative arc that includes increasingly intense combat situations, relational development, stress and loss, and emotional trauma. The goal is to raise the service member's threshold for the stress of combat.","PeriodicalId":220761,"journal":{"name":"2012 IEEE Virtual Reality Workshops (VRW)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116004970","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 server is used to visualize the virtual representation of the real environment, 3d features map where augmentation are to occur, augmented content that will be rendered and users avatar that evolves on the field. The user's WS is equipped of a Head Mounted Display (HMD) along with sensors (GPS/DRM/Compass) to provide constant pose estimation (position and orientation) to the CC and a vision based tracking that uses natural features and pose estimation allgorithms to render virtual content accordingly. Alternatively a sensor based renderer is used to display AR guidance on the HMD based on the path defined and sent from the CC. The natural features system handles a large number of small 3D features maps.

The state-of-the-art techniques employ various rendering algorithms to simulate physically accurate light transport for generating the photorealistic appearance of scene. However, they still require a labor-intensive tone mapping and color tunes by an experienced artist. In this paper, we propose an automatic photorealism enhancement algorithm by manipulating the color distribution of graphics to match with that of real photographs. Based on the hypothesis that photorealism is highly correlated with the frequency of color characteristics appearing in real photographs, we find principal color components. Then, we transfer the statistical characteristics of photographs onto graphics so to enhance their photorealism. Experiments and a user study have confirmed the effectiveness of proposed method.","PeriodicalId":220761,"journal":{"name":"2012 IEEE Virtual Reality Workshops (VRW)","volume":"49 s171","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120835076","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}
