An evaluation of 3-D emotion space

The goal of the research is to realize a very natural human-machine communication system by giving a facial expression to a computer. The 3-D emotion space previously proposed, can represent both human and computer emotion conditions appearing on the face compactly in 3-D space. Namely, this 3-D emotion space can also realize both mapping and inverse mapping from facial expression to this 3-D space. This paper is mainly about the subjective evaluation using the synthesized facial expression from the 3-D emotion space.
