As business going global, people in different countries and sites use web conference for communication. With current technologies, people can detect who is speaking and his/her chat history in a web conference. However, the currently known technologies do not provide a solution that can detect real-time emotion of the participants in a web conference. Knowing the real-time emotion of the conference participants can better facilitate communication. So, how to detect users' emotion? This invention detects conference participants’ emotion by capturing their real-time photos when they activate the dialog box. The emotion photo is sent out along with the messages as the user's portrait. Whenever users send out new messages, their emotion when they typing the message will be sent out simultaneously. Therefore, the portrait is updated in real time. The portrait can be dynamic graph or static graph. The function of this invention is optional. If you don't want to initiate this function, you can disable it.
