While mainstream haptics has been focusing on training elite skills, the haptic simulator described in this paper addresses a problem with a phenomenal social impact that addresses teaching of vocational skills to the growing unskilled and impoverished populations in India. This is an unconventional attempt at designing a multi-tool haptic trainer that could potentially replace traditional training tools and materials in the primary stages of vocational skill training. After an exhaustive analysis of all the tools used in the various vocational trades of the construction industry, we categorized and sorted the tools based on their properties and functions. Using this information, we designed Amrita Progressive Training Assistance using Haptic simulation (APTAH), a cost effective haptic simulator that can train the use of over nineteen hand-held and powered tools used in several vocations. The simulator provides audio, visual and haptic cues that can help the novice master the use of the tools in the absence of a human trainer. This paper also discusses the preliminary trials conducted to study training effectiveness of the haptic simulator proposed.
