ABSTRACT

Emotional reaction of audience can be decided by observing reaction of audience for content. We canuse a method to analyze visual data from video camera to detect reaction of audience fast andeconomically. This paper proposes the method and system to observe audience reaction from visual dataof audience and define via neural network. Also we propose a new method to detect automatically an areafor audience reaction with face detection to improve a fixed area assignment method which has a limitation not to adapt depending on audiences. Additionally, the evaluation is implemented to show that the proposedmethod and system is effective. The proposed method showed the performance elevation of 10.5 % (7.75hit ration) compared to a fixed area assignment method.
