A Visual Sensory Evaluation of the Results of Two Pattern Grading Methods

Abstract

Current apparel production methods grounded in a tradition of master-apprentice training and intuition are being challenged by the introduction of Artificial Intelligence. Much of the expert knowledge needed to develop computer systems for the apparel industry is related to visual decisions made to create a garment. In this study, a sensory evaluation methodology was used to determine if visual perceptual differences existed between results of pattern grading methods using traditional and proportional techniques. An expert panel of eleven members evaluated visual effect of images graded across an entire size range. Three sets of images representing apparel on the body were selected to emphasize (1) horizontal proportion, (2) vertical proportion, and (3) proportion of details. Responses of panel members indicated neither traditional nor proportional grading maintained the visual effect referenced in the sample size across the entire size range. The goal of pattern grading needs to be redefined to account for the desired visual effect in a variety of size and body variations.
