Verbal communication has limits in the interaction between robot and man, and therefore nonverbal communication is required for realizing smoother and more efficient communication and even the emotional expression of the robot. This study derived 7 pieces of nonverbal information based on shopping behavior using the robot designed to support shopping, selected facial expression as the element of the nonverbal information derived, and coded face components through 2D analysis. Also, this study analyzed the significance of the expression of nonverbal information using 3D animation that combines the codes of face components. The analysis showed that the proposed expression method for nonverbal information manifested high level of significance, suggesting the potential of this study as the base line data for the research on nonverbal information. However, the case of 'embarrassment' showed limits in applying the coded face components to shape and requires more systematic studies.

The purpose of this study was to identify the effect of gesture and facial expression on persona effects. Fifty-six college students were recruited for this study, and non-verbal communication skills were applied to a pedagogical agent with gesture (conversational vs. deictic) and facial expression. The conversational gesture may have relationship with social interaction hypothesis of pedagogical agent while the deictic gesture may have relationship with attentional guidance hypothesis. The facial expression can be assumed to facilitate the social interaction between the pedagogical agent and learners. Interestingly, the conversational gesture group showed a tendency of outperforming the deictic gesture group. It may imply that the social interaction theory has a strong impact on cognitive support as well as social interaction for learners. There was a significant interaction effect on the engagement when both of facial expression and conversational gesture were applied. This result has two implications. First, facial expression can facilitate the persona effect for engagement.

People tend to perceive their loved others (e.g., children, spouse, romantic partner) as their extended selves and then control over the loved others' fashion style corresponding to their self-concept. The study conceptually suggested that people's perceptions on legitimacy to interfere the others and their own fashionability would separately or interactively influence their control over the loved others' fashion style. To investigate the suggestions, an experiment with female participants in their 20's was conducted by using a scenario. The results indicated that participants' perception of legitimacy to interfere their boyfriends or their own fashionability did not have a separate effect on control over their boyfriends' fashion style. However, the legitimacy and the fashionability did have an interactive effect on the control. In particular, for high legitimacy groups, there was no difference in the control between low and high fashionability groups. For low legitimacy groups, the control was stronger in high fashionability group than in low fashionability group.

Positive affect has beneficial consequences in various life domains including social relational aspect. This study proposes that 'joy,' a highly arousing positive social emotion, promotes emotionally supportive reactions during a social interaction. In Study 1, after controlling for confounding personality characteristics (e.g., extraversion, agreeableness, adult attachment) and cognitive variables (e.g., empathy, self-esteem), positive affect predicted the amount of emotional support and enthusiasm one showed to a person who was describing a positive experience. The arousal dimension of positive emotion appeared to be the key in creating this outcome. Study 2 found that people were most likely to react in supportive ways (e.g., more laughing, emotion sharing, and active-constructive responses) to other's conversation after viewing a joy-inducing (rather than pride, awe, calm) film clip. These results partly explain why happy people are socially popular and suggest that one of the central functions of "joy" is to promote social bonding with others.

The use of service robots, particularly guide robots, is becoming increasingly prevalent in public institutions. However, there has been limited research into the interactions between users and guide robots. To explore the customer experience with the guidance robot, we selected 'QI', which has been meeting customers for the longest time, and collected all reviews since the service was launched in public institutions. By using text mining techniques, we identified the main keywords and user experience factors and examined factors that hinder user experience. As a result, the guide robot's functionality, appearance, interaction methods, and role as a cultural commentator and helper were key factors that influenced the user experience. After identifying hindrance factors, we suggested solutions such as improved interaction design, multimodal interface service design, and content development. This study contributes to the understanding of user experience with guide robots and provides practical suggestions for improvement.

최근 온라인 게임을 비롯하여 영화, 애니메이션 등 가상현실에서 캐릭터가 중심적인 역할을 하게 되었고 좀 더 능동적이고 사람에 가까운 캐릭터 개발이 필요하게 되었다. 이러한 요구 중에서 본 논문에서는 감성기반 캐릭터에 초점을 맞추었고 Emotion Al사의 Artificial Emotion Engine Model과 OCC Model를 바탕으로 각 캐릭터의 특성을 반영하고 캐릭터간의 상호 작용을 바탕으로 감성을 도출해 낼 수 있는 Emotion Engine의 Architecture를 제시한다.

IT(Information Technology)분야의 발전과 함께 RT(Robot Technology)분야도 21세기의 유망한 첨단기술로 손꼽히고 있다. 현재의 로봇은 그동안 주류를 이루던 산업용 로봇과는 달리 소프트컴퓨팅, 인간친화 인터페이스, 상호작용기술, 음성인식, 물체인식, 사용자 의도파악 등 갖가지 최첨단 기술들이 요구되는 퍼스널 로봇이 각광을 받고 있으며, 특히 오락용, 교육용 로봇들로 대표되는 엔터테인먼트 로봇(Entertainment Robot)분야가 요즘 국내·외에서 활발히 연구되고 있는 실정이다. 엔터테인먼트 로봇은 정형화된 작업만을 하는 것이 아니라 다양한 환경에서 여러 가지 작업을 해야만 한다. 따라서, 장난감 로봇처럼 인간과의 감정대화가 가능한 지능 시스템을 갖춰야만 한다. 그러므로 본 논문에서는 IT분야와 RT분야의 접목으로 시너지 효과를 크게 얻을 수 있는 새로운 기술 개념인 RCP(Robotic Cellular Phone)에 대한 개념을 정의하고, RCP의 기능성 모듈 중 하나인 감성발향 모듈에 대한 기본적인 이론과 실험적 결과를 통하여 로보틱 셀폰의 감성발향 모듈의 우수성을 확인한다.

Attentional blink is observed in an identification task of multiple targets during rapid serial visual presentation (RSVP) where performance for the second target (T2) that follows within 500ms of the first (T1) shows systematic decrease although that for T1 remains highly accurate. Theories accounting for attentional blink can be classified into two broad categories of resource depletion model and disruption of input filter model. Meanwhile, visual attention capacity shows hemifield independence between left and right visual fields, and many studies reported bilateral advantage in a range of visual working memory tasks. The current research tested two major theories of attentional blink using bilateral independence of attentional capacity. To this end, we conducted two experiments where two RSVPs were presented in either bilateral or unilateral visual fields. Experiment 1 presented two RSVPs which contained both T1 and T2 in either bilateral or unilateral visual fields and tested interaction between attentional blink and bilateral advantage. Experiment 2 removed T1 in one of the two RSVPs to test whether attentional blink obtains when identification of T1 and T2 utilize independent sources of attention across two visual fields. The results showed that subjects were more accurate when two RSVPs were presented in bilateral visual fields (i.e., bilateral advantage) although there was no interaction between attentional blink and bilateral advantage (Experiment 1). In addition, attentional blink for T2 was observed in a T1-absent RSVP even when two RSVPs were presented in bilateral visual fields (Experiment 2). These results support disruption of input filter model rather than resource depletion model.
