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.

Abstract: Method of generating depth estimate based on biometric data starts with server receiving positioning data from first device associated with first user. First device generates positioning data based on analysis of a data stream comprising images of second user that is associated with second device. Server then receives a biometric data of second user from second device. Biometric data is based on output from a sensor or a camera included in second device. Server then determines a distance of second user from first device using positioning data and biometric data of the second user. Other embodiments are described herein.

Abstract: Method of creating shared AR session based on a gesture starts with server receiving observed motion data from first device associated with first user. First device generating observed motion data based on an analysis of data stream comprising images of second user performing a gesture. Second user being associated with second device. Server receiving from second device captured motion data that corresponds to the gesture. Captured motion data being recorded by a sensor included in second device. Server determines whether there is a match between observed motion data from first device and captured motion data from second device. In response to determining that there is the match, server generates shared AR session between first device and second device and causes shared AR session to be displayed by first device and second device. Other embodiments are described herein.
