The tactual sensation scaling was first performed to obtain a linear sensation scale of the display by means of the JND (just noticeable difference) method. One-dimensional curves on the scale were displayed to investigate human sensitivity to an intensity change rate. A tactile texture presentation method based on the image of an object surface is introduced, and two kinds of experiment were performed. Texture discrimination is the first, in which the effect of texture element size on the correct separation was discussed. Then the sensations produced by the display and that by a real object were compared using several samples that had vertical lines and did not contain low frequencies. The results are summarized and further research directions are discussed.","PeriodicalId":333190,"journal":{"name":"Proceedings of IEEE 1997 Annual International Symposium on Virtual Reality","volume":"50 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":"116818966","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}

Fire and smoke effects are added to simulate actual firefighting conditions. This paper describes the feasibility tests that were performed aboard the Shadwell and presents promising results of the benefits of VE training over conventional training methods.","PeriodicalId":333190,"journal":{"name":"Proceedings of IEEE 1997 Annual International Symposium on Virtual Reality","volume":"366 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":"113998302","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}

With a denser matrix of mounted pins, it can be expected that shape identification will become easier and the time required for identification will also become shorter, but that problems of difficulty in fabrication will arise. It is necessary to consider such trade-offs in the development of such devices. The authors conducted experiments to study the effect of pin pitch on shape identification as part of the fundamental investigation of this subject. The experiment used three tactile display devices with pin pitches of 2 mm, 3 mm and 5 mm for geometrical shape identification, with response time and rate of misidentification taken as the performance data. Surfaces, edges and vertices of three-dimensional shapes were used as the shape primitives for displayed shapes and several of each type were selected for presentation. The results obtained revealed that performance has different relationships to pin pitch with different shape primitives.","PeriodicalId":333190,"journal":{"name":"Proceedings of IEEE 1997 Annual International Symposium on Virtual Reality","volume":"433 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":"132793893","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}

While conventional methods use a small set of discrete LODs, we introduce a new class of polygonal simplification: Smooth LODs. A very large number of small details encoded in a data stream allows a progressive refinement of the object from a very coarse approximation to the original high quality representation. Advantages of the new approach include progressive transmission and encoding suitable for networked applications, interactive selection of any desired quality, and compression of the data by incremental and redundancy free encoding.","PeriodicalId":333190,"journal":{"name":"Proceedings of IEEE 1997 Annual International Symposium on Virtual Reality","volume":"36 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":"125760275","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}
