We have developed a system to simulate various common tool exercises and procedures in virtual environments for vocational training programs targeted towards illiterate and semi-literate populations. In our previous work, we designed a cost-effective multi-tool haptic simulator that can train the use of 19 hand-held and powered tools. This simulator is designed to replace traditional training tools and materials in the primary stage of vocational skill training. This paper discusses the design and computational modelling of the virtual training interface that allow this simulator to be used for training in multiple vocational trades - with a special focus on plumbing-that bring the experience of a vocational workshop training environment to the end user. This approach of a virtual, computer-based vocational training environment holds the potential to offer vocational training to a diverse audience with varying skill sets.","PeriodicalId":440723,"journal":{"name":"2014 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE) Proceedings","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116830756","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}

Due to advances in the 3D graphics and in the computing power, the real-time visual rendering of a virtual world poses no significant problems nowadays. However, the haptic interaction with such environments remains a challenge. This paper explores the haptic interaction with a dedicated virtual environment in spider phobia treatment to elicit disgust, as changes in fear and in disgust were shown to be highly associated with the observed decline in arachnophobic symptoms. A dedicated virtual environment is programmed within which a Novint Falcon haptic device is used for the interaction with a virtual spider. Different software options for interfacing with the haptic device and for the modeling of 3D objects are compared and discussed. Three testing scenarios are implemented that allow a subject to be gradually exposed to his/her spider phobia.","PeriodicalId":440723,"journal":{"name":"2014 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE) Proceedings","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128805817","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}
