Haptics enhanced multi-tool virtual interfaces for training carpentry skills

This paper presents the design and computational modelling of a virtual simulator of a multitool, for training vocational skills in a hands-on way. Here we describe the audio-visual-haptic elements for the customized simulation interfaces for training carpentry tools and skills and the computational mathematical model to render haptic feedback for these actions. Finally the paper will explain the trainee's skill learning curves through these simulations, based on analysis of data from user studies. In our previous work, we designed a haptic training simulation interfaces for plumbing tools as part of Computerized Vocational Education and Training (CVET). As an extension to this we had developed a cost effective system to simulate various common tool exercises and procedures in virtual environments with a special focus of carpentry. Proposed system is designed to replace conventional training in the initial stage of vocational skill training and fasten the skill learning process to a diverse audience with varying skill sets.
