Development of a textile sensibility evaluation system

As the demand in the market for a product with a high sensibility has dramatically increased, research has been conducted in designing products for better sensibility; however, most studies have employed a paper-and-pencil (P&P) questionnaire in administering a sensibility evaluation, causing a lack of efficiency and systematicity in sensibility research. The present study developed a computerized textile sensibility evaluation system which can be used to efficiently evaluate the visual, tactile, visual-tactile, and auditory sensibilities of textiles and examined its effectiveness in visual sensibility evaluation compared with the traditional P&P evaluation method. The computerized evaluation system has capabilities of managing information of textile properties, designing a sensibility evaluation experiment, administering a sensibility evaluation, and managing evaluation data for post hoc analysis. The test-retest protocol was administered with a within-subject design for 15 females in their 20 s and 30 s to examine the difference in visual sensibility evaluation between the P&P method and the computer-based method. A high correlation (r=.88～.97) was found in sensibility evaluation between the two methods and the computer-based system showed a higher repeatability within a rater in repeated evaluation (a decrease of 25 % in intra-rater SD), which indicates the computer-based method is an effective alternative to the P&P method in visual sensibility evaluation. The findings of the present study support use of a computerized system for practitioners to efficiently identify preferred characteristics of textiles for the design of sensible clothing.
