Abstract: A video playback system for jointly displaying video with multiple screens, includes multiple portable communication devices each comprises at least one screen; a location detection circuit for dynamically detecting respective portable communication device's spatial location and orientation; and a multi-screen display controlling server for dynamically generate multiple partitioned videos respectively corresponding to multiple non-overlap image areas of a target video according to detection results of the location detection circuit. The multi-screen display controlling server respectively transmits the multiple partitioned videos to the multiple portable communication devices. The multi-screen display controlling server controls the multiple portable communication devices to respectively display the multiple partitioned videos on the multiple screens to jointly display at least a portion of a visible area of the target video.

Abstract: A video playback system for enhancing drama effect is disclosed, including: a video playback device having a main display to playback a target video; a first portable communication device having a first screen for displaying a first auxiliary image; and a drama effect enhancing server configured to operably transmit content of the target video to the video playback device via a network and to operably transmit content of the first auxiliary image to the first portable communication device via a network. When the target video playbacked on the main display reaches a first target point of time, the drama effect enhancing server instructs the first portable communication device to utilize the first screen to begin displaying the first auxiliary image.

Abstract: 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 location 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, the source electronic device transmits a target command corresponding to the target image object to a candidate electronic device of the member electronic devices to perform corresponding multimedia interaction operations only if a relative position between the candidate electronic and the target direct satisfies a predetermined condition.

Abstract: A multimedia interaction system is disclosed, including: a plurality of member electronic devices; a plurality of deplays 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 candicate 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 candicate electronic and the target direct satisfies a predetermined condition.

Abstract: A multimedia interaction system is disclosed, including: a plurality of member electronic devices; a plurality of deplays respectively arranged on the member electronic devices; a forwarding electronic device configured as a command transmission intermedium between 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, the forwarding electronic device transmits a target command corresponding to the target image object to a candidate electronic device of the member electronic devices to perform corresponding multimedia interaction operations only if a relative position between the candidate electronic and the target direct satisfies a predetermined condition.
