Communication robots’ impressions will be changed through long-term use in human-robot communications because of novelty effect and familiarity effect. To measure changes to the impression, we created a scale of psychological assessment by conducting a long-term experiment. We focus on characteristic nature and tool-like nature of communication robots. We used our scale to evaluate changes of the impressions by the use of Kiropi v2, RoBoHoN and iPad in another long-term experiment. Results showed that scores corresponding to characteristic nature and tool-like nature of impression will basically improve the more users use it. In addition, some impressions showed non-linear changes due to novelty effect and familiarity effect. The results also showed that the impressions differed between the robots, indicating that the impression of Kiropi v2 was the best. The psychological scale developed in this study may be useful for future developers of communication robots when they want to evaluate their impressions of robots for long-term use.
