What does a 3D call look like?

See a live capture appear in another person’s space.

Made for remote conversations

What would you like them to see?

Choose a camera for the person, object or place you want to share.

Front camera · TrueDepth

Let them see you in 3D

Share your face, gestures and upper-body movement during a remote conversation. The other person sees your live 3D capture in their space and can move around it.

Requires an iPhone or iPad with a TrueDepth camera.

Rear camera · LiDAR

Show what you’re talking about

Point the rear camera at an object or part of a room. Give the other person a live 3D view of what you’re discussing, including its shape and movement.

Requires an iPhone Pro or iPad Pro with a LiDAR scanner.

The camera captures color and depth. The other person sees a live 3D shape made of colored dots, called a point cloud. Each capture shows the surfaces visible to the camera.

If hand tracking does not work. On the very first launch, hand tracking may fail, so you cannot interact and the hand object does not appear at your hand position. In that case, disconnect the XREAL glasses from the XREAL Beam Pro (just unplug the USB cable), connect them again, and launch the app again.
Known issues

Troubleshooting

Connection error

In highly secure network environments (offices, schools, public Wi-Fi) the device's IP address cannot be obtained, and the point cloud cannot be streamed. Use tethering from a smartphone, or another network.

The receiver shows nothing

Check that the Connection ID is exactly the same on both sides, and that the sender app is still open and shows Live.
