Difference of Affective Response to Haptic Feedback

다국어 초록 (Multilingual Abstract)

Recently kansei-engineering approach on various products and feedback has been carried out, affective response on haptic modality also has gained greater attention. The aim of this study is to analyze the effect of mode of haptic on affective response. In order to analyze the perception characteristics according to haptic mode, the experiments with jog dial were divided into active <haptic> where the participants were directly involved with controlling devices and into passive <haptic> where the participants remained uninvolved. 9 haptic feedbacks represented by specific sine wave having width, magnitude, detent type, and detent width were provided to users utilizing simulator devices. Six affective variables, perspicuity, smoothness, heaviness, elasticity, liltingness, and satisfaction, were evaluated by 25 subjects. Averages of affective elements in each mode were compared and change pattern according to haptic feedback parameter was investigated through statistical analysis. As a result, perspicuity, heaviness and elasticity were perceived larger when the mode was set to active haptic, while smoothness was perceived larger in passive haptic, and perspicuity and heaviness have shown significant difference according to haptic mode (α<0.05). Experiment result shows that the affective elements related with difference of force are largely evaluated in active haptic than in passive haptic and assessment according to magnitude of stimuli was not consistent in passive haptic. This study shows that haptic stimuli should be larger than intended to provide intended feedback to user under context of virtual reality using passive haptic mode.
