10. A method for acquiring and processing interaction information of a user watching a multimedia material comprising: controlling a display device to play a multimedia material in at least one display region; controlling a detector to acquire a comment about a user watching the multimedia material on the display device; storing a plurality of interaction information related to the multimedia material in a database, wherein each of the plurality of interaction information corresponds to more than one index tag which comprises time information, corresponding to a timestamp of a video frame image of the multimedia material displayed in the at least one display region, and/or position information, corresponding to at least one position in the at least one display region; surveying the index tags in the database with a processing module according to the comment acquired by the detector, wherein when one of the index tags matches the comment, the processing module outputs a content of the interaction information corresponding to the index tag to at least one electronic device; outputting a mistake command to the electronic device by the processing module when none of the index tags matches the comment, so the electronic device links to a cloud society web interface through a network.
