Hugging provides psychological benefits and is common in supportive dialogue, leading to probabilistic models for a robot's intra-hug gestures (e.g., patting, rubbing). However, the psychological effects of this human-derived model have not been adequately verified. In this study, we aimed to clarif
Mainstream use of AI has enabled human-like conversations with machines. Despite the perceived naturalness of these interactions, they are limited to 2D screens. Androids offer us an opportunity to explore the third dimension, touch, with a human-centered approach. In this work we developed and eval
The potential of social touch, a behavior that uses physical embodiment, has been actively studied for adaptation to social robots because of both physical and mental benefits. Social touch from robots, including hugs, reports positive effects similar to human-human interaction. Huggable robots have
With the expansion of social robots’ working environments, developing strategies to mitigate their mistakes has become crucial, especially given the difficulty of entirely avoiding errors. Previous studies have explored effective strategies for robot apologies, including conversational content, yet
One essential role of social robots is supporting human mental health by interaction with people. In this study, we focused on making people's moods more positive through conversations about their problems as our first step to achieving a robot that cares about mental health. We employed the column
This letter addresses the effects of grip timing to express a robot's emotions to people while they are watching a video stimulus together. Past studies on human-robot touch interaction focused on the types of touch behaviors for expressing a robot's emotion, but timing factors have received less at
We propose a wearable tactile sensor suit, which can be regarded as tactile sensor networks, for monitoring natural body dynamics to be exploited as a computational resource for estimating the posture of a human or robot that wears it. We emulated the periodic motions of a wearer (a human and an and…
Kawaii, a Japanese word that means "cute," is an essential design concept in consumer and pop culture in Japan. In this study, we focused on a situation where a social robot describes an object during an information-providing task, which is commonly required for social robots in daily environments.…
This study investigated the effects of touch characteristics that change the strength and the naturalness of the emotions perceived by people in human-robot touch interaction with an android robot that has a feminine, human-like appearance. Past studies on human-robot touch interaction focused on un
When a person interacts with others who require different levels of authority, his/her gaze ratio and body direction for each person are different, e.g., a salesperson who turns to and looks at a very important person (VIP) more attentively than a member of that VIP's staff. In this study, we invest
This study addresses the pre touch reaction distance effects in human-robot touch interaction with an android named ERICA that has a feminine, human-like appearance. Past studies on human-robot interaction, which enabled social robots to react to being touched by developing several sensing systems a
People engage in social coordination without explicitly communicating when they are conflicting over spatial resources, e.g., a shop clerk who yields to customers the best place to view products. In this study, we proposed a method that achieves such social coordination with a robot. Our idea is tha…
