Evaluation support system which control emotional level of crowd ~ Performance evaluation using various majority synching bias models~

Abstract

In Great East Japan earthquake (March 11, 2011), it is reported that many people did not evacuate in spite of advanced warnings, and tsunami took many people’s lives. In contrast, in conflagrations of airplanes, it also reported that victims could not escape from the airplane because of a panic. This phenomenon is called majority synching bias. In general, we tend to sympathize with others’ emotion in crowd, and it prevents evacuation. Therefore, if we control the emotional level of the crowd to appropriate tension, we can extremely reduce the number of victims. In our previous works, we proposed a framework to control emotional level of a crowd by employing robots and avatars. In this research, we conduct many simulations using various majority synching bias models, and we evaluate the effectiveness of the proposed framework.
