During the previous field study with a robot and its interaction with mall visitors, we observed a surprising event during which a leaflet-distributing robot was abused, although it was subsequently helped by one of its previous abusers. After analyzing 72.25 hours of video data, we identified 47 cases where a robot dropped a leaflet and classified...

Both qualitatively and quantitatively, we analyzed the phenomenon of children who engage in such serious abuse as kicking and punching robots by observing their first encounter with the robot to serious abuse and finally leaving the robot. In study 1, we established a process model of robot abuse and used a qualitative analysis method: the Trajecto...

The present study aimed to investigate whether individuals with high social anxiety prefer robots over humans as their exercise/sports partner. This study included a questionnaire survey with 520 Japanese participants (mean age=44.39, SD=14.33). The results showed that for all exercise-/sports-related situations, participants who selected robots as...

In the present research, we prepared a human-size humanoid that autonomously navigates alongside with a walking person. Its utterances were controlled by Wizard-of-Oz method. A field experiment in which older persons walked in an elder care facility together with the robot while it talked to them was conducted to investigate the effects of robot ac...

This study investigates whether people prefer robots versus humans as communication partners for different roles and situations in daily life, and the influence of social anxiety on people's preferences for robots versus humans among young Japanese. A total of 206 young Japanese (men: 103, women: 103; mean age: 25.2 years, SD = 2.91 years, range: 2...

To investigate whether people with social anxiety have less actual and “anticipatory” anxiety when interacting with a robot compared to interacting with a person, we conducted a 2 × 2 psychological experiment with two factors: social anxiety and interaction partner (a human confederate and a robot). The experiment was conducted in a counseling sett...

This study investigates: (1) whether people prefer robots over humans as communication partners for different purposes and in different situations in daily life in conjunction with appearance of the robots; and (2) the influence of social interaction avoidance on people’s preference for robots over humans in conjunction with appearance of the robot...

We found that children sometimes abused a social robot placed in a shopping mall hallway. They verbally abused the robot, repeatedly obstructed its path, and sometimes even kicked and punched the robot. To investigate the reasons for the abuse, we conducted a field study in which we interviewed visiting children who exhibited serious abusive behavi...

We found that children sometimes abuse a social robot in a hallway of a shopping mall. They spoke bad words, repeatedly obstructed the robot's path, and sometimes even kicked and punched the robot. To investigate why they abused it, we conducted a field study, in which we let visiting children freely interact with the robot, and interviewed when th...

The above results suggest the following fact; only if persons feel higher anxiety toward communication capacity of robots, their anxiety toward discourse with robots increases when the robot looks the other way during interaction with them, and decreases when the robot fixes the face. It means an interaction effect between a specific type of robot...

Attitudes toward robots, in particular, negative attitudes are important factors influencing human perception and behaviors toward robots. The chapter surveys the existing studies using the Negative Attitudes toward Robots Scale for measuring these attitudes, and then reports a current study based on a social research, showing influences of experie...

At Disney, we are storytellers, and all good stories are filled with compelling characters. One way to present these characters to audiences in immersive, 3D environments is through the use of entertainment robots, or Audio Animatronics Figures, as they ...
