An information processing device including a control unit that controls a display terminal that arranges a virtual object in a real space by using a coordinate system associated with the real space, in which the control unit determines whether to update first spatial information of a first display terminal and second spatial information of a second display terminal, which are used for determining a position of the virtual object, based on a first operation state of the first display terminal and a second operation state of the second display terminal that shares the virtual object with the first display terminal.
