A recent survey found that online shoppers return 70 percent of the clothing they order, more than any other category of purchase. This has an indirect but real impact on the environment.
Online shoppers tend to order multiple sizes and colors, with the intent of sending back the items that don't fit or aren't the right color, a practice known as "bracket shopping." An augmented reality (AR) tool allowing shoppers to see an image of themselves in the garment, however, made them more likely to want to buy it, according to new research by a team including Fatma Baytar, assistant professor of fiber science and apparel design and director of the Body Scan Research Group. While not as effective as physically trying it on, the researchers found that AR boosted participants' attitudes toward the garment, potentially improving the experience and efficiency of online shopping. "Bracket purchases increase shelving and shipping costs," Baytar said. "We're hoping these technologies can reduce those costs, while also decreasing the carbon footprint associated with return shipping."
Avatar or AR
Current virtual try-on technologies offer two methods of improving online shopping. One involves creating an avatar by inputting key body measurements and then trying clothes on the avatar. The other method is AR - using a computer, phone or tablet screen as a mirror reflecting a shopper and background while overlaying the chosen garments on the shopper' image. Baytar and collaborators from Iowa State University and Virginia Polytechnic Institute focused on the latter technology, asking participants to virtually try on a dress, select a size to "order" and then physically try on the dress in that size. Participants evaluated the AR dress for size, fit and performance, then did the same following the physical try-on.
Mixed results for AR technology
According to Baytar, study participants were able to find the right size with AR try-on, but had trouble evaluating the fit - particularly at the bust, waist and hips. One explanation, Baytar said, was that although the image of the dress was taken when the dress was on a dress form, rather than hanging flat, it was still a 2D image. Adding to the difficulty evaluating fit: The dress form's hourglass shape did not match the body shape of all participants. Evaluating product performance - style, fabric, color, coordination with other items, touch and feel, weight, fit, comfort and appearance on the body - was significantly different when experienced in AR versus real life. Color was the only performance factor that showed no difference across the two try-on experiences. But even with the limitations, participants responded well to the virtual dress.
Attitudes towards AR garment
"Attitudes to the AR garment and the real garment were really high, which means the participants liked it and their purchase intentions were relatively high, though they were higher for the real garment," Baytar said. "This is still a promising technology, because AR can provide good visual information that improves consumer attitudes and purchase intentions. We think a company could use this technology to create a buzz when introducing a new style." Baytar and her colleagues also wanted to know how telepresence - consumers' sense of being present in a virtual environment - would impact their attitudes toward the AR garment and purchase intentions. As expected, the study showed that higher telepresence corresponded to more positive attitudes toward the AR garment.
The study was completed in 2016 but has new significance, Baytar said, with brick and mortar stores being closed during the COVID-19 crisis. "The technology we used was limited, and even four years later the technology still needs to be improved," Baytar said. "We can expect that as these technologies evolve, people will trust online shopping more, they will trust that they will get the right size that fits them and will look like it did on the screen."
