Incorporating Tactile Cues into Human-Centered Virtual Product Design

This study introduces a high-fidelity tactile feedback mechanism to capture ergonomics attributes of users inside virtual product development cycle. The research question posed regards whether the tactile feedback mechanism in virtual experiment proposes high fidelity of ergonomics results when compared to physical experiment outcomes. This question was evaluated through an objective and a subjective study. Objective study was composed of an ergonomics product assessment experiment, where two different cart designs a commercial cart and a prototype model were evaluated for ergonomic adequacy L4/L5 compression forces. Subjective evaluation was consisted of a questionnaire to assess subjects' preferences regarding which cart model they preferred in three different design categories; maneuverability, accessibility, and ergonomics. Results showed that tactile feedback mechanism was able to replicate the physical test conditions in virtual environment with high fidelity, and prototype cart model received higher mean ratings when compared to commercial cart model in each design category.
