Estimate emotion method to use biological, symbolic information preliminary experiment

Abstract

Imagine the day that a robot would comfort you when you feel sad. To achieve the ability to estimate emotion and feeling, a lot of work has been done in the field of artificial intelligence [1] and robot engineering that focuses on human robot communications, especially where it applies to therapy [2, 3]. Generally, estimating emotions of people is based on expressed information such as facial expression, eye-gazing direction and behaviors that are observable by the robot [4–6]. However, sometimes this information would not be suitable, as some people do not express themselves with observable information. In this case, it is difficult to estimate the emotion even if the analysis technologies are sophisticated. The main idea of our proposal is to use biological information for estimating the actual emotion of people. The preliminary experiments show that our suggested method will outperform the traditional method, for the people who cannot expressed emotion directly.
