The visual requirements of their experimental tasks were similar to those needed for visually guided manual assembly of aircraft wire harnesses. In the first experiment subjects visually traced wire paths with a head referenced cursor, subjectively rated aspects of viewing, and had their vision tested before and after monocular, biocular, or stereo viewing. Only the viewing difficulty with the biocular display was adversely effected by the visual task. This viewing difficulty is likely due to conflict between looming and stereo disparity cues. A second experiment examined the precision with which operators could manually move ring shaped virtual objects over virtual paths without collision. Accuracy of performance was studied as a function of required precision, path complexity, and system response latency. Results show that high precision tracing is most sensitive to increasing latency. Ring placement with less than 1.8 cm precision will require system latency less than 50 msec before asymptotic performance is found.","PeriodicalId":333190,"journal":{"name":"Proceedings of IEEE 1997 Annual International Symposium on Virtual Reality","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130832245","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 Electrical Vestibular Stimulus (EVS) technology described in the paper uses electrodes located behind the ears to deliver a low level electrical current in the vicinity of the eighth cranial nerve of the central nervous system to produce a compelling sensation of roll motion about the body's fore-aft axis. In the study described, subjects experienced the EVS display while simultaneously observing a large field of view visual display which depicted curvilinear motion through a tunnel. Both EVS and visual displays were driven in a sinusoidal fashion at various phase relationships relative to one another. After observing the two displays, subjects were asked to rate various aspects of quality and magnitude of self motion. Results revealed that the fidelity of the motion experience depended upon the phase relationship between the EVS and visual displays. Results also indicated that when an appropriate phase relationship was used, the vestibular display significantly improved the fidelity of the motion experience when compared to a visual only display.","PeriodicalId":333190,"journal":{"name":"Proceedings of IEEE 1997 Annual International Symposium on Virtual Reality","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128577681","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}
