Although for many applications data entry is not a requirement, for some it is essential: communicating in collaborative environments, entering a filename to which work can be saved, or accessing system controls. Combining data gloves and a graphically represented keyboard with a predictive spelling paradigm, we describe an effective text entry technique for immersive environments; we explore the key issues when using such a technique, and report the results of preliminary usability testing.","PeriodicalId":375222,"journal":{"name":"IEEE Virtual Reality 2004","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117075413","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 task was to answer a set of questions based on Crook's condensation of Bloom's taxonomy to assess the participants' cognition of a virtual room with respect to knowledge, understanding and application, and higher mental processes. Participants were also asked to draw a sketch map of the testing virtual environment and the objects within it. Users' sense of presence was measured using the Steed-Usoh-Slater presence questionnaire. Our results suggest that for applications where problem solving and interpretation of material is important, or where opportunity to train is minimal, then having a large tracked space so that the participant can physically walk around the virtual environment provides benefits over common virtual travel techniques.","PeriodicalId":375222,"journal":{"name":"IEEE Virtual Reality 2004","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116759971","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 study the degradation of the information quality caused by the existence of network latency on a simple virtual task model, Markov model is employed.

The results of subjective experiments show that, in average, the accuracy of human foreseeing behavior marked between the score of the first and second order Markov models.","PeriodicalId":375222,"journal":{"name":"IEEE Virtual Reality 2004","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125341150","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 present a new technique, navigation with place representations and visible landmarks that scales from town-sized to planet-sized worlds. Visible landmarks make distant landmarks visible and allow users to travel relative to those landmarks with a single gesture. Actual and symbolic place representations allow users to detect and travel to more distant locations with a small number of gestures. The world's semantic place hierarchy determines which visible landmarks and place representations users can see at any point in time. We present experimental results demonstrating that our technique allows users to navigate more efficiently than a modified panning and zooming W1M, completing within-place navigation tasks 22% faster and between-place tasks 38% faster on average.","PeriodicalId":375222,"journal":{"name":"IEEE Virtual Reality 2004","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130482339","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 first level computes an error-minimizing rigid body transform that eliminates the need for precise alignment of a tracker base frame. The second corrects for field warp by interpolating correction values stored with vertices in a tetrahedrization of warped space. The third performs an alternative field warp calibration by interpolating corrections in the parameter space of a tricubic spline model of field warp. The system is evaluated for field warp calibration near a passive-haptic panel in both low-warp and high-warp environments. The spline method produces the most accurate results, reducing median position error by over 90% and median orientation error by over 80% when compared to the use of only a rigid body transform.","PeriodicalId":375222,"journal":{"name":"IEEE Virtual Reality 2004","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130437856","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}
