When the impression evaluated by the impression evaluation unit 5 is the value X of value, the value Y of activity, and the value Z of competence, the psychological model, for example, converts physical property information to p _X , p _Y , p _Z biological information. Can be represented as formulas (1) to (3), respectively, as q _X , q _Y , and q _{Z.
X = a X q X + b} X p X + c X ... (1)
_{Y = a Y q Y + b} Y p Y + c Y ... (2)

As mentioned above, although this invention was described by embodiment, it should not be understood that the description and drawing which form a part of this indication limit this invention. From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art.

  For example, in the above-described embodiment, the plurality of psychological models in the model storage unit 9 include the relationship between the first to fifth physical property information, the first to fourth biological information, and the impression on the target P at a predetermined timing, and The model may represent a time-series relationship from a predetermined timing. For example, there is a difference in the impression between when the subject Q has an impression of the target P for the first time and when the subject Q has an impression of the target P after the next time, and a pattern may be found. Further, there are cases where a pattern can be found in the time-series ecological behavior of the subject Q depending on the impression of the subject Q such as the preference. As described above, when the psychological model represents the time-series relationship between the physical property information and the biological information, the impression of the subject Q with respect to the target P can be evaluated with high accuracy by a change with time from a predetermined timing. .

  In addition to the above, it goes without saying that the present invention includes various embodiments that are not described herein, such as configurations to which embodiments and modifications of the present invention are applied. Therefore, the technical scope of the present invention is defined only by the invention specifying matters according to the scope of claims reasonable from the above description.
