METHOD, DEVICE AND SEVER FOR DATA SYNCHRONIZATION

A method, a device and a server for data synchronization comprises: establishing communication connections with at least two terminals using different motion-capture systems, and receiving motion-capture data sent by at least one terminal that is successfully connected; after receiving the motion-capture data sent by at least one terminal that is successfully connected, preprocessing the motion-capture data; and sending respective preprocessed motion-capture data items to the other successfully-connected terminals excluding the terminal corresponding to the given motion-capture data item. The solution connects multiple terminals to the same server, and each time the server receives motion-capture data sent by one terminal, the motion-capture data is preprocessed and sent to all other terminals, excluding said one terminal. Thus, even when motion-capture data of multiple terminals is acquired by different optical motion-capture systems, data communication and synchronization are unaffected.
