A team of academics in Hong Kong have developed a 3D human modeling app that could drastically change the way we shop online. Dubbed 1Measure, this “one-click measure” tool allows users to record their body measurements in a matter of seconds by uploading two full-body photos.

After snapping images with both a front view and side view, the app uses artificial intelligence to create a 3D digital model of the user's body in under 10 seconds. Next to this image, over 50 size measurements are displayed, including everything from knee girth to shoulder slope. This information can be saved and accessed at a later date, and the app also lists your size in other countries, allowing you to shop for clothes around the world with ease.

This revolutionary technology was developed by associate professor Tracy P.Y. Mok and PhD graduate Dr. Zhu Shuaiyin of the Institute of Textiles and Clothing at The Hong Kong Polytechnic University (PolyU).

Other current technologies are capable of carrying out similar modeling functions, but the PolyU team says these methods involve costly, bulky scanners, and their results are only approximate. The 1Measure app’s margin of error is 1 centimeter for users photographed in tight-fitting clothes, and 2 centimeters for those in loose-fitting clothes, according to its developers.

The app is particularly useful when it comes to online shopping. Dr. Zhu says the technology “frees us from the limitations imposed by taking body measurements physically, helping customers to select the right size in online clothing purchases.”

The app can also store multiple measurements at once and track any changes that the body undergoes, making it suitable for those with fitness goals.

1Measure is free to download and is currently available on the App Store in both English and Chinese.
