The concept of entropy which was introduced as a thermodynamic property has been extended to the economics theory, information theory, and others. Even though “entropy” is used in many fields of science, it is not easy to understand the concept of entropy, as well as describing it by words/terms. We assume that one of the causes of such difficulty is the gap between psychological quantity caused by words/terms used in explaining the concept of entropy and actual entropy value. In this report, we investigated the correlation between the entropy and the psychological quantity obtained by showing binary dot pattern images to participants, and examined the correlation between the entropies calculated by several different algorithms and the psychological quantity by three verbal expressions. We have found that the entropy calculated by means of measuring the length between each black pixel has highest correlation to psychological quantity.

The concept of entropy which was introduced by Clausius in 1850 as a thermodynamic property has been extended to the economics theory, information theory, and others. Even though “entropy” is used in many fields of science, it is not easy to understand the concept of entropy, as well as describing it by words/terms. In this paper, we investigated an appropriate way of representing the concept of entropy by words. At first, we surveyed the commonly used words in describing the concept of entropy. We pointed out the problem that the language expression does not accurately represent the entire concept of entropy. Secondly we examined the correlation between the thermodynamic entropy calculated from the particle animations simulating the molecular motion and the psychological quantity obtained by showing those animations to participants. As a result, we found that the representation of the word “degree of diffusion” has relatively good correlation with the entropy value.

ネットワークを介したAVコンテンツ視聴時におけるユーザ主観評価を効率よく、かつ、精度よく推定する手法について研究する。具体的には、ユーザに装着する各種の生体情報測定器及びセンサ、並びに、ユーザが使用するデバイスから得られる多次元情報より、ユーザ主観評価を、ユーザ毎の違い、ユーザの満足度や興味、ユーザコンテクストを考慮し、かつ、リアルタイムに推定する手法を研究する。
