Haptic simulations for training plumbing skills

The objective of this work is to augment actual hands-on conventional vocational training workshop with simulated training using virtual haptic simulations as part of computer-based vocational education and training. 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.
