Psychophysical testing of garment size variation using three-dimensional virtual try-on technology

Abstract

This study investigated the level of garment size variation that viewers could perceive with three-dimensional (3D) virtual try-on technology and examined how accurately the technology allowed viewers to perceive the size variations. The viewers' perceptions were measured by two psychophysical experiments, rating tests and ranking tests. The stimulus was a set of 3D virtual pants in 11 different sizes, simulated on a virtual model of the same size. Participants evaluated the size differences of the test pants compared to the control pants on a rating scale. They also ranked the six pants, in random order, from the smallest to the largest size. The results showed that the viewers could rate larger sizes as larger and smaller sizes as smaller, proportionally. In addition, the technology allowed the viewers to rank different sizes of virtual pants in the correct order. Overall, the virtual try-on technology had the capacity of showing size variations clearly enough for viewers to perceive and discriminate the size differences.
