Design and Implementation of Kawaii Robots by Japanese and American University Students using Remote Collaboration

This paper describes our approach to the design and implementation of virtual Kawaii robots and spaces by Japanese and American university students using remote collaboration. Because of the COVID-19 pandemic, we had to change our planned 7-week collaboration from in-person to virtual with a resultant change in the target product of our collaboration from real robots to virtual robots. Based on our new plan, students designed virtual spaces with robot pairs, proposed evaluation items for the robot pairs, evaluated their designs, and analyzed the results. The students designed each robot pair with the goal that one robot would be more kawaii and the other would be less kawaii due to a variation in a single attribute such as shape or color. The evaluation instrument used adjective pairs that were suitable to evaluate the affective values of the robot pairs and the virtual spaces the robots occupied. Through the design experience, students learned a lot about Kawaii Engineering and affective evaluation, which gave them a deeper understanding of Japanese culture from the viewpoint of Kansei/Affective Engineering

Cross-Cultural Affective Evaluation of Kawaii Robots in Virtual Spaces

In modern society, robots have been increasingly involved in human lives in various scenarios. As a future society with human-robot interaction is approaching, it is important to consider how to develop robots that give positive impressions for a variety of users. Based on an Affective Engineering approach, affective values can strengthen the impact of the first impressions of products. Kawaiiness is one affective value that can be a key factor in developing robots with positive impressions. In this research, we carried out a collaborative project to design and develop kawaii robot prototypes in virtual spaces by American and Japanese university students. We then performed an experiment on affective evaluation of those robots using 10 adjectives: kawaii/cute, approachable, scary, trustworthy, cool, beautiful, polite, comfortable, and soft. We previously presented our statistical analysis results for the adjective “kawaii/cute.” However, the results of other adjectives, which potentially have effects on the robot impression, have not been presented yet. Therefore, in this paper, we present our further analysis of several adjectives to clarify their relationship with kawaii/cute and robot features across genders and cultures. In addition, we statistically analyzed the effects of robot pairs, adjectives, genders, and cultures. The results suggest that robots with features such as more animal-like, rounder, and shorter tend to increase positive impressions such as kawaii, approachability, beauty, comfortable, and softness. Also, we found no difference across gender and culture for the impressions on kawaii robots, which shows the possibility of expanding the concept of kawaii robots worldwide
