The objective of this study is to examine the effect of the robot types on emotional engagement with robots. Robots are classified into an autonomous robot and a tele-operated robot according to the levels of autonomy. On the contrary, robots could be distinguished depending on the levels of human intervention required for controlling a robot. An autonomous robot performs task by itself while a tele-operated...
In order to investigate what type of experiences of robots influences negative attitudes toward them, an online survey (N = 1,200) was conducted in Japan, by using the Negative Attitudes toward Robots Scale (NARS). The results suggested that (1) there were almost no strong relationships between types of robot experiences and gender, and age, (2) the correlations between negative attitudes toward robots...
We performed an experimental study (n=48) of the effects of context congruency on human perceptions of robotic facial expressions across cultures (Western and East Asian individuals). We found that context congruency had a significant effect on human perceptions, and that this effect varied by the emotional valence of the context and facial expression. Moreover, these effects occurred regardless of...
Pointing is a typical means of directing a human's attention to a specific object or event. Robot pointing behaviours that direct the attention of humans are critical for human-robot interaction, communication and collaboration. In this paper, we describe an experiment undertaken to investigate human comprehension of a humanoid robot's pointing behaviour. We programmed a NAO robot to point to markers...
This paper presents results from a user evaluation of a robot bartender system, which supports social engagement and interaction with multiple customers. The system is a Nao-based alternative version of an existing robot bartender developed in the JAMES project [1]. The Nao-based version has given us a local experimentation platform, allowing us to focus on social multi-user interaction rather than...
This research explored whether robots can use modern speech synthesizers to convey emotion with their speech. We investigated the use of MARY, an open source speech synthesizer, to convey a robot's emotional intent to novice robot users. The first experiment indicated that participants were able to distinguish the intended emotions of anger, calm, fear, and sadness with success rates of 65.9%, 68...
This study proposes a gaming companion robot to facilitate social interaction among children. Games have been one popular social communication tool for people, and we propose a novel approach to gaming communication using a robot. We have implemented a robot that is capable of playing a video game to facilitate social interaction in a game environment. We used autonomous control to allow the robot...
In human - robot interaction many different signals are used by robots in order to get a proper environment representation. Even more so, the social robots, whose primary task is to maintain successful interaction with humans, should use input signals in order to model the human itself. One important human characteristic is the human emotional state. As a result, perceiving human emotions is one challenging...
This paper presents a model for developing long-term human-robot interactions and social relationships based on the principle of ‘human’ cognitive biases applied to a robotic platform. The aim of this work is to study how a robot influenced with human ‘misattribution’ can help to build better human-robot interactions than unbiased robots. The results presented in this paper suggest that it is important...
Within the scope of the current research the goal was to develop an autonomous transport assistant for hospitals. As a sort of social robots, they need to fulfill two main requirements with respect to their interactive behavior with humans: (1) a high level of safety and (2) a behavior that is perceived as socially proper. One important element includes the characteristics of movement. However, state-of-the-art...
Recent research indicates that other factors in addition to appearance may contribute to the “Uncanny Valley” effect, and it is possible that “uncanny actions” such as “robot telepathy” - the nonverbal exchange of information among multiple robots - could be one such factor. We thus specifically examine whether humans are negatively affected by displays of nonverbal robot-robot communication through...
When two or more people perform actions together such as shaking hands, playing ensemble music or carrying an object together, they often naturally adjust the spatial and temporal parameters of their movements to facilitate smooth task performance. This paper reviews recent findings from experiments with human participants to demonstrate ways in which individuals strategically modulate their own action...
This paper presents the results from an experiment with a conversational human-robot interaction system aimed at long-term support for diabetic children. The system offers a set of activities aimed to help a child to improve its capability to manage diabetes. There is a large body of literature on the techniques that artificial agents can use to establish and maintain long-term social-emotional relationships...
