Amazon has launched a new augmented reality (AR) app called “Amazon AR Player” that works with quick response (QR) codes on shoppers’ Amazon boxes to create shareable, immersive experiences.

Available for free on the iOS App Store and Google Play, Amazon AR Player provides shoppers a fun way to interact with their boxes before recycling them. To bring the AR assets to life, users must point their smartphone camera at the QR code on their Amazon box.

The new AR boxes, which just started rolling out, are labeled with the name of the experience and offer three-step instructions on how to activate it. The boxes are made with less material as part of the company’s ongoing sustainability campaign “Less Packaging, More Smiles.”

At launch, the app only offers a Halloween-themed AR experience. But as per the screenshots on the App Store, Amazon AR Player will feature a variety of AR experiences. For example, one screenshot shows an Amazon box transforming into a small blue AR car, while another shows someone drawing the face on a pre-printed white pumpkin, which upon scanning turns into an AR jack-o-lantern.

Amazon also notes in the App Store description that if your phone supports TrueDepth technology, the app will use your smartphone camera to track your facial movements to enable features like its selfie mode.

If you don’t have an Amazon package, you can still experience the app by printing a label here and using their phone to scan the QR code.

Amazon has slowly been ramping up its AR offerings. In August, the company launched a tool compatible on mobile and desktop called Room Decorator that lets you design an entire room with multiple home decor items. The tool also lets you add products to your shopping cart and see recommendations of similar items.

To access Room Decorator, users can click the “View in Your Room” button that appears under qualifying products in the Amazon mobile app on iOS and on desktop.

The Room Decorator tool is the advanced iteration of Amazon’s AR View, which it debuted in 2017 to enable online shoppers to see how one furniture item would look in their living space.
