Design and Implementation of Kansei Engineering System Presenting Virtual Tactile Sense and Consideration of its Effects on User's Kansei

Abstract

A VR-based Kansei engineering system presenting not only visual but also tactile sense is proposed and its prototype is developed. Target design is custom kitchen. We apply the method of presenting virtual haptic in the previous study to a traditional Kansei engineering system which visualizes target's design based on the design rules. This approach leads the user to watch the design explaining Kansei which the user demands and to touch one of the parts of its design. Furthermore, the function of presenting virtual tactile sense is expanded and a framework which the user can touch through the network is proposed. In evaluation experiments, it was confirmed that participants had different Kansei when visual and tactile information was presented than when visual information only.
