서비스 로봇의 지각과 행동에서의 신뢰성은 각 개별 요소기술의 완벽함으로부터 얻어지는 것이 아니라 비록 성능이 불완전한 요소기술들을 사용하더라도 각 요소기술들의 정보를 융합하고 능동적인 행위를 발생시키는 시스템적인 접근방식으로부터 얻어진다. 그러므로 본 연구에서는 자연스러운 HRI 구현을 위하여 "로봇인지 엔진"이라는 독창적인 통합 구조를 제안하였으며, 비동기/병렬 정보처리 구조, 다양한 지각정보들의 융합, 행위 결합을 위한 능동적인 지각정보 수집의 특징을 갖는다.

최근 컴퓨터를 이용하여 사용자와 상호작용 하는 과정에서 사용자의 정서 상태를 파악하고, 이에 대응하여 적절한 행동을 할 수 있는 감성 캐릭터 생성에 대한 연구가 요구되고 있다. 특히 캐릭터 애니메이션에 있어서도 애니메이터의 수작업이나 외부 장비를 이용하지 않고, 캐릭터의 감성 상태에 따라 애니메이션을 자동으로 생성할 수 있다. 본 논문은 이러한 감성 시스템을 설계하고 캐릭터의 감성에 따라 애니메이션 하는 방법을 제안한다. 본 연구에서는 캐릭터에 감성을 부여하기 위하여 Ortony의 인지적 정서 모델을 바탕으로 하여 새로운 감성 모델을 제안하였고 이를 바탕으로 물고기 캐릭터에 적용하여 시스템을 구현하였다.

본 작품은 어떻게 보여줄 것인지에만 치중된 증강현실 개발 환경에서 어떻게 인간과 상호작용 할 것인가에 대한 고민이 부족하다고 생각하여 본 캡스톤디자인을 시작하였다. 손가락에 착용하는 반지형태의 디바이스와 이를 이용한 증강현실 조작 인터페이스를 구현하는 것을 목표로 한다. 이를 위해서 모바일 Video-Through HMD 증강현실 환경을 만든 뒤 증강된 객체의 배치, 이동, 회전과 같은 조작을 구현하였다.

인터넷상의 정보가 빠르게 변화함에 따라 정보의 최신성을 유지하며 웹 상의 정보를 통합하기 위한 실시간 웹 통합 방법들이 제안되고 있다. 하지만 대부분이 실시간 추출에 소요되는 시간이 너무 긴 단점을 가진다. 본 논문에서는 추출시간을 줄이기 위해 입력 질의를 분리하여 사용자와 상호작용하며 단계적으로 웹 통합을 수행하는 방법을 제안한다. 실험을 통해 기존 방식과 응답시간을 비교하여 유용성을 확인하였다.

Recently, many researchers have studied on agent-based edutainment systems to improve students' learning experience. In this paper, we present AR Gardening which makes users experience interactive flower gardening with a bluebird, a learning companion agent, squatting in an augmented picture. The proposed system augments the animated bluebird to support interactive edutainment experiences. The bluebird perceives users' actions as well as environmental situations. It then appraises situational information to provide participants with problem-solving guidelines. Moreover, the bluebird responds like a companion than an instructor through anthropomorphic expression. To demonstrate our work, we exhibited the implemented AR Gardening and reviewed participants' responses to the system. In this exhibition, we could find that the learning companion-like bluebird helped users experience how to properly grow the flower in our educational setting. Ultimately, we expect that an augmented peer learning agent is one of the key factors for developing effective edutainment applications.

As evolution of multimedia technology brings changes to industries concerned with design, new education program is needed to cultivate designers with abilities which are adapted to changed circumstance. This paper is purposed to show guideline to set up a fundamental course for multimedia design in which students know what are new presentation modes and learn how to use them, Multimedia design call for abilities of organizing information, representing, and implementing interactivity. Among them, fundamental course considers representing information as central subject. And it also contains lessons which are relative to proceeding courses. It should have students to experience creative composition and various expressions, and study cognitive or aesthetic effects of them. All activities are based on the understanding about presentation factors and principles. Basic course's lessons are composed by two main subjects, which are essential expression and matters relative to organization and interactivity. Described in detail, lessons are divided into three phases. First phase is combining presentation factors for affective effects, second is delivering message of various knowledges and third is forming simple interaction.

전자피부(Electronic skin)는 외부 환경과의 상호작용하는 인간 피부의 기능을 대체하여 외부 자극 신호를 전기적 신호로 변환하는 센서들로 이루어진 인공피부로써, 최근 인간과 전자기기 간의 인터페이스에 대한 관심이 급증하면서 이에 대한 많은 연구들이 진행되고 있다. 그중에서도 피부의 주된 기능인 외부 물리적 자극을 인지하는 촉각을 모방하는 촉각센서는 많은 발전을 거쳐 왔으며, 한계를 극복하고자 다양한 연구들이 진행되고 있다. 촉각센서는 압력, 인장, 굽힘과 같은 물리적 자극에 반응하며, 물리적 자극 신호를 아날로그 및 디지털 신호로 변환하여 인지하는 연구들이 폭넓게 개발되고 있다. 또한, 소자의 구조에 따라 물리적 자극을 전달하는 다양한 변환 방식들이 있으며, 최근에는 각 신호 변환 방식의 민감도, 반응속도, 자극 인지 범위 등의 한계점을 극복하고, 소재의 기계적 물성을 향상시키기 위해 소재의 변형을 주거나 생체의 기관 구조 및 외부 자극 인지 원리 등을 모사한 연구들이 많은 관심을 받고 있다. 본 기고에서는 이러한 촉각센서의 물리적 자극 신호 변환 방식과 소재 변형 및 생체 모사를 통한 다양한 연구들을 소개하고자 하며, 이를 통하여 촉각센서의 나아갈 방향을 제시하고자 한다.

Social media marketing should be approached in a different way from traditional media marketing. This study uses a theoritical and empirical method to analyze what impact social media's key elements - provide information, interactivity and playfulness - have on corporate performance and awareness. As a result, the increase in the level of provide information, and the level of interactivity turned out to have positive impact on corporate performance and awareness. To improve the impact of social media on corporate performance, it is better to use it more extensively for customer management and marketing, rather than simply focusing on a specific part of social media. In conclusion, it is important to have a better understanding of the key elements of social media in order to improve corporate performance and image. In a situation where senior firms are increasingly adopting social media, it is increasingly important to have social media-related PR marketing subject included in senior education.

This study focused on causes of use reluctant intention because closed SNS was more active than open SNS was despite tremendous growth of SNS to have negative influence upon not only SNS contents suppliers but also marketing business using SNS. The survey were conducted a total of 205 participants with adult over colleague student, 197 copies that excluded questionnaire with unfaithful answer were used in the analysis, and we used path analysis of structural equation modeling. The results of modified path model showed that interactivity was influenced by value, and then affecting "trust ${\rightarrow}$ satisfaction ${\rightarrow}$ using reluctant intention" path and "satisfaction ${\rightarrow}$ using reluctant intention" path. These result reflected that interactivity have a double-edged sword and value is very important standard to make a positive of negative role of interactivity. These results suggested that interactivity was found to have influence upon not only behavioral willingness that took actions depending upon either improvisation or situation but also behavioral intention path that thought and took actions in reasonable way. The interactivity had double-edged sword to help develop SNS and to produce negative results.

SNS is in the process of fast evolution as well. This study is about influence of authenticity and interactivity among Facebook Fan Page users. Authenticity is something people form in the process of expressing and sharing information thru SNS Facebook Fan Page. Interactivity is a level of participation of users in the process of expressing and sharing information thru SNS Facebook Fan Page. The focus of this paper is to see the power of authenticity and interactivity of SNS Facebook Fan Page users in a time of crisis. Authenticity is proven as a valuable asset for corporations for it showed a sturdy characteristic even when something terrible happened. When a crisis attacked, high authenticity user group was not willing to change their evaluation on a company reputation and image as much as low authenticity user group. Interestingly enough, the meaning interactivity level was strikingly different from what we expected. The more their level of interactivity, was the more they were likely to change their evaluation on a company in a time of crisis. A serious discussion is necessary for this contraty results.
