Publication number: 20260299704Abstract: 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.Type: ApplicationFiled: June 3, 2026Publication date: October 1, 2026Inventors: Piers George Cowburn, David Li, Isac Andreas Müller Sanduik, Qi Pan
