The purpose of this study is to investigate the effect of textile touch visualization on e-commerce web site. Two e-commerce web sites (Gap and Anthropology) were selected and 160 female subjects took part in this study. To visualize the tactile sensation, clothing materials of each brand was measured by KES and the values were displayed in bar chart. This visualized tactile information, lightness, and washing method was added on the original web site. Each brand had two web sites (one is with original, the other is modified with added information) and 40 participants answered the questionnaire on each web site. The questionnaire was constructed with two parts which would be answered before and after touch. In results, the modified web sites showed a significant difference between 'no visual information' and 'with visual information' on most of the questions. This may indicate that the modified web sites provide enough tactile information about clothing material to customers more accurately. However, both modified web sites didn't show any significant difference between before and after touching while the original web sites showed significant difference.
