지능형 로봇의 인간-로봇 상호작용(Human-Robot Interaction)은 현재 세계적으로 주목받는 연구 분야 중 하나이다. 이 논문에서는 지능형 로봇의 작업 완결성을 높이기 위한 방편의 일환으로 사용자에게 작업 내용을 공개하고, 문제 발생 시 사용자의 개입을 유도하는 형태의 인간-로봇 상호작용을 제안한다. 이러한 형태의 서비스는 지능형 로봇이 작업 수행 중 필요한 경우 사용자의 선택 통해 예상치 못한 상황에 대해 유연한 대처를 할 수 있으며, 동시에 로봇의 현재 상황을 사용자가 확인할 수 있도록 하는 수단을 제공한다. 이를 위해 이 논문은 Android 플랫폼과 로봇 간의 로봇-사용자 정보교환을 구현하고, 나아가 범용적이고 일반적인 인간-로봇 상호작용을 위한 연구방향을 제시하고자 한다.

This paper describes the configuration of a multi-agent system that can recognize human intentions. This system constructs ontologies of human intentions and enables knowledge acquisition and sharing between intelligent agents operating in different environments. This is achieved by using a bi-directional associative memory network. The process of intention recognition is based on fuzzy association inferences. This paper shows the process of information sharing by using ontologies. The purpose of this research is to create human-centered systems that can provide a natural interface in their interaction with people.

In this paper, we analyzed how 5-year-old children perceive a robot's ability to attribute mental states to oneself and to others, which shall hereafter be referred to as a robot's theory of mind (RToM). A total of 34 5-year-old children were given two typical false-belief tasks, an 'unexpected-contents task' and a 'change-of-location task', in order to evaluate whether a child's perceived RToM was connected to their own ToM. In addition, we investigated whether a child's perception of RToM was influenced by either a priori experience with robots or that child's gender. The results are as follows. Firstly, the 5- year-old preschool children universally recognized robots as beings that have a human-like mind both in 1st order and 2nd order perspectives, which indicates that children perceive robots as beings distinct from mechanical toys. Secondly, a priori child-robot interaction experience was found to have a positive influence on a child's perceived RToM. Thirdly, the gender of children did not significantly affect their perceived RToM. This study serves to add to the macroscopic results of prior research, which indicate that children perceive robots as intermediate beings between living and inanimate objects: significantly, it analyzes the children's perception of robots through the lens of theory of mind, which is one of the key elements of cognitive development. This research lays the foundations for designing effective child-robot interactions, in situations in which robots serve as peers or assistants for educational purposes.

The robot has recently emerged as a factor in the daily lives of humans, taking the form of a mechanical pet or similar source of entertainment. A robot system that is designed to co-exist with humans, i.e., a coexistence-type robot system, is important to be "it exists in various environments with the person, and robot system by which the interaction of a physical, informational emotion with the person etc. was valued". When studying the impact of intimacy in the human/robot relationship, we have to examine the problems that can arise as a result of physical intimacy(coordination on safety in the hardware side and a soft side). Furthermore, We should also consider the informational aspects of intimacy (recognition technology, and information transport and sharing). This paper reports the interim results of the research of a system configuration that enhances the physical intimacy relationship in the symbiosis of the human and the robot.

Recently, studying on modeling the emotion of a robot has become issued among fields of a humanoid robot and an interaction of human and robot. Especially, modeling of the motivation, the emotion, the behavior, and so on, in the robot, is hard and need to make efforts to use our originality. In this paper, new modeling using mathematical formulations to represent the emotion and the behavior selection is proposed for the software robot with virtual sensor modules. Various Points which affect six emotional states such as happy or sad are formulated as simple exponential equations with various parameters. There are several experiments with seven external sensor inputs from virtual environment and human to evaluate this modeling.

Human Robot Interaction(HRI) through a haptic interface plays an important role in controlling robot systems remotely. The augmented usage of bio-signals in the haptic interface is an emerging research area. To consider operator's state in HRI, we used bio-signals such as ECG and blood pressure in our proposed force reflection interface. The variation of operator's state is checked from the information processing of bio-signals. The statistical standard variation in the R-R intervals and blood pressure were used to adaptively adjust force reflection which is generated from environmental condition. To change the pattern of force reflection according to the state of the human operator is our main idea. A set of experiments show the promising results on our concepts of human adaptive interface.

본 연구는 인공지능 로봇이 높은 수준의 음악적 창작물을 제시할 때 로봇과 인간과의 협업정보 유무와 함께 로봇과의 비교영역의 자기관련성 정도가 사용자의 로봇에 대한 시기심, 창작한 음악에 대한 예술성의 평가와 태도, 그리고 향후 창작 음악을 사용하고 로봇과 협업할 의도에 미칠 영향을 검증했다. 2(비교영역 자기관련성: 낮음(음악 비전공자) vs. 높음(음악 전공자)) × 2(작업유형: 로봇 홀로 작업 vs. 로봇과 인간의 협업)의 집단 간 요인 설계 실험으로 진행하였다. 연구 결과, 자기관련성이 높았던 음악 전공자들에 비해 자기관련성이 낮았던 비전공자들이 로봇의 능력에 대하여 더 높은 시기심을 갖고 있는 것으로 나타났다. 그러나 음악 전공자들은 로봇이 창작한 음악의 예술성을 더 낮게 평가했고, 음악에 대한 태도도 더 비호의적이었고, 향후 음악을 사용할 의도와 로봇과 협업할 의도를 더 낮게 보고 했다. 한편, 인간과의 협업 정보 여부는 시기심을 비롯한 종속변인에 유의미한 영향을 주지 않았다.

최근 인공지능 기술의 비약적인 발전에 따라 전천후 로봇 판매원이 실현될 가능성이 부각 되고 있다. 그러나 소비자가 로봇의 설득 메시지를 어떻게 평가하고 반응하는지를 실증적으로 탐구한 연구는 부족하다. 본 연구는 로봇이 제품을 판매하려는 설득 의도를 현저하게 드러내고 로봇과의 물리적 거리가 가까워질 때 소비자의 로봇에 대한 평가와 로봇이 광고하는 제품에 대한 구매 의도에 어떻게 영향을 미칠지를 탐색했다. 이를 위해 2(로봇의 설득의도: 낮음 vs. 높음) × 2(로봇과의 물리적 거리: 보통 vs. 매우 가까움)의 총 4개 집단 간 요인 설계 실험을 진행하였다. 연구결과, 로봇이 드러내는 설득 의도가 높다고 인식할수록 참가자들은 로봇의 전문성과 신뢰성을 낮게 평가하고 로봇이 광고한 제품인 노트북을 구매할 의도도 낮게 보고하는 것으로 나타났다. 한편 참가자들은 로봇이 자신에게 다가오는 거리의 정도와 상관없이 로봇의 전문성과 신뢰성을 비슷하게 평가했지만, 로봇이 자신의 개인 공간으로 가까이 다가올 때에는 로봇에 대하여 더 부정적으로 평가했고 그 제품을 구매할 의도도 낮게 보고했다.

A telerobot offers a more engaging and enjoyable interaction with people at a distance by communicating via audio, video, expressive gestures, body pose and proxemics. To provide its potential benefits at a reasonable cost, this paper presents a telepresence robot system for video communication which can deliver speaker's head motion through its display stanchion. Head gestures such as nodding and head-shaking can give crucial information during conversation. We also can assume a speaker's eye-gaze, which is known as one of the key non-verbal signals for interaction, from his/her head pose. In order to develop an efficient head tracking method, a 3D cylinder-like head model is employed and the Harris corner detector is combined with the Lucas-Kanade optical flow that is known to be suitable for extracting 3D motion information of the model. Especially, a skin color-based face detection algorithm is proposed to achieve robust performance upon variant directions while maintaining reasonable computational cost. The performance of the proposed head tracking algorithm is verified through the experiments using BU's standard data sets. A design of robot platform is also described as well as the design of supporting systems such as video transmission and robot control interfaces.
