The invention provides a multimedia teaching control system and method. The system comprises a data collecting module which is used for collecting video streaming. The multimedia teaching control system is characterized in that an interaction control module is further included, the collected video streaming is processed, the outline of a figure is identified through an image identification technology, the central point and the convex hull points of the outline are calculated to determine the positions of hands, then an instruction is judged according to the stay time of the hands, and therefore corresponding response actions are made. According to the multimedia teaching control system and method, the interaction control module and the control method enable a teacher to do not need to use hardware equipment such as a mouse and a keyboard, corresponding buttons can be triggered by pointing to an object to be operated by fingers to set time, interactive control over courseware is achieved, and the lecturing mode is more flexible. The entire multimedia teaching control system and method improve the enjoyment of a lesson, the teaching mode is innovated, and a better teaching effect is achieved.
Description
