  • MARKER-BASED SHARED AUGMENTED REALITY SESSION CREATION
    Publication number: 20210201530
    Abstract: Method for creating marker-based shared augmented reality (AR) session starts with initializing a shared AR session by a first device and by a second device. The first device displays on a display a marker. The second device detects the marker using a camera included in the second device and captures an image of the marker using the camera. The second device determines a transformation between the first device and the second device using the image of the marker. A common coordinate frame is then determined using the transformation, the shared AR session is generated using the common coordinate frame, and the shared AR session is caused to be displayed by the first device and by the second device. Other embodiments are described herein.
