To evaluate the kansei values of interactive systems, subjective evaluation methods such as questionnaires are commonly used, even though they have some drawbacks such as linguistic ambiguity and interfusion of experimenter and/or participant intention to the results. We began our research to objectively evaluate interactive systems by quantifying sensations using biological signals to redeem the above questionnaire drawbacks. We utilize biological signals to estimate participants' feelings of relaxation, comfort, and excitement, which are considered positive sensations. However, relaxation and comfort are considered static compared with dynamic feelings such as excitement. We focus on a positive and dynamic feeling called wakuwaku in this chapter, and construct various systems to evaluate the kansei values used to derive wakuwaku feelings using biological signals, in order to clarify the relationship between the wakuwaku feeling and biological signals. In addition, we derive a kansei model of interactive systems using biological signals to objectively evaluate their wakuwaku degree.
