A three-dimensional (3D) interactive method between a 3D interactive input device including multiple first nodes and a 3D display device including at least three second nodes is provided. The method includes receiving a start command from a user and controlling signal transmission devices to transmit position detection signals using different channel resources based on the received start command. The method also includes determining 3D spatial position coordinates of the first nodes relative to a specific surface based on a starting time point of the start command, ending time points, and 3D spatial position coordinates of the second nodes relative to the specific surface. Further, the method includes rebuilding 3D contour of the 3D interactive input device to determine gestures of the 3D interactive input device and implement a 3D interactive process based on the 3D spatial position coordinates of at least two first nodes relative to the specific surface.
