Abstract
People love companion animals as part of the family. However, recently there are some problems such as the anxiety about caring for animals and a lack of space to breed companion animals; therefore, companion robots are expected to be an alternative to companion animals. For the development of companion robots that are loved by their owners, it is necessary to know how attached the owners are to their companion robot. However, previous evaluation methods based on interviews or questionnaires only measure the degree of the owner’s attachment at the time when the evaluation is conducted; hence periodic measurement needs to be repeated to measure long-term changes in attachment. In this paper, we focus on the activity logs of the companion robot, which is highly objective and can be collected at a low cost, and examine the possibility of using the data as an evaluation indicator of the owner’s attachment degree. We compared the robot activity logs with questionnaire-based attachment ratings collected from companion robot owners (N = 259). We found that owners who highly rated their attachment to the companion robot in the subjective evaluation questionnaire were more likely to interact with the robot, such as holding the robot and calling the robot’s name. The result indicates the possibility of using robot activity logs as an objective indicator of the owner’s attachment degree.
