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.

Can Virtually Trying on Apparel Help in Selecting the Correct Size?

“…Another technique is to 3-D scan the garment (i.e., dressed on a body) and then analyze the visual correspondence with the real garment (Bye & McKinney, 2010;Song & Ashdown, 2010;Zhang, Zhang, & Xiao, 2011). Other researchers used 2-D patterns that were placed, curved, and simulated on an avatar and later evaluated against their similarities to a real garment (Kim & LaBat, 2013a, 2013bSong & Ashdown, 2015) or virtual sizes were ranked and sorted according to size (Kim, 2016).…”

Enhancing the online decision-making process by using augmented reality: A two country comparison of youth markets

“…The lack of direct experience in touching, feeling, smelling and trying on an item makes the evaluation difficult and may negatively affect enjoyment and the purchase decision (Beck and Crié, 2016;Blázquez, 2014;Merle et al, 2012). Major concerns and problems are fit and size (Kim, 2016;Lin and Wang; 2016, Shin and Baytar, 2014), or matching with other items (Chen and Wang, 2010). Virtual try-on systems, as application of augmented reality for retailing, can overcome the main limitation of online channels related to the possibility to try the products before the effective buying (Baum and Spann, 2014).…”

Effects of 3D Virtual “Try-On” on Online Sales and Customers’ Purchasing Experiences

“…Another study evaluated that visualization of size variations was enough for viewers to perceive size differences, which means that this size visualization could be used in the fit analysis of grading samples. As a result, manufacturers can replace fit analysis of size grading samples and need not make multiple samples in various size grades or hire multiple fit models of various sizes [10]. However, virtual fitting is limited and has issues that must be addressed before virtual technology can be completely trusted as a visual fit analysis tool.…”

“…Most previous studies on virtual fitting or virtual try-on (VTO) have focused on technology [5,6,7], the effects and effectiveness [8,9,10,11], and consumer behavior [12,13,14]. These were either studied on its technology in design chain from the point of view of making clothes, or studies on effects and behavior from the point of view of customers.…”
