A multimedia interaction system is disclosed, including: a plurality of member electronic devices; a plurality of displays respectively arranged on the member electronic devices; and a location detection circuit configured to operably detect respective member electronic device's spatial position and orientation dynamically and to transmit detection results to at least one of the member electronic devices. When an user instructs a source electronic device of the member electronic devices to transmit a target image object toward a target direct, a candidate electronic device of the member electronic devices would execute a target command corresponding to the target image object to utilize a corresponding display to perform a multimedia operation corresponding to the target image object only if a relative position between the candidate electronic and the target direct satisfies a predetermined condition.
