Electroencephalography(EEG) studies that have been in clinical research since the discovery of brainwave have recently been developed into brain-computer interface studies. Currently, research is underway to manipulate robot arms and drones by analyzing brainwave. However, resolution and reliability of EEG information is still limited. Therefore, it is required to develop various technologies necessary for measuring and interpreting brainwave more accurately. Pioneering new applications with these technologies is also important. In this paper, we propose development of a personal authentication system fit for lifecaretainment based on EEG. The proposed system guarantees the resolution and reliability of EEG information by using the Electrooculogram and Electromyogram(EMG) together with EEG.

Most recently, CP(Cellular Phone) has been one of the most important technologies in the IT(Information Tech-nology) field, and it is situated in a position of great importance industrially and economically. To produce the best CP in the world, a new technological concept and its advanced implementation technique is required, due to the extreme level of competition in the world market. The RT(Robot Technology) has been developed as the next generation of a future technology. Current robots require advanced technology, such as soft computing, human-friendly interface, interaction technique, speech recognition, object recognition etc. unlike the industrial robots of the past. Therefore, this paper explains conceptual research for development of the RCP(Robotic Cellular Phone), a new technological concept, in which a synergy effect is generated by the merging of IT & RT. RCP infra consists of $RCP^{Mobility}$ $RCP^{Interaction}$, $RCP^{Integration}$ technologies. For $RCP^{Mobility}$, human-friendly motion automation and personal service with walking and arming ability are developed. $RCP^{Interaction}$ ability is achieved by modeling an emotion-generating engine and $RCP^{Integration}$ that recognizes environmental and self conditions is developed. By joining intelligent algorithms and CP communication network with the three base modules, a RCP system is constructed. Especially, the RCP mobility system is focused in this paper. $RCP^{Mobility}$ is to apply a mobility technology, which is popular robot technology, to CP and combine human-friendly motion and navigation function to CP. It develops a new technological application system of auto-charging and real-world entertainment function etc. This technology can make a CP companion pet robot. It is an automation of human-friendly motions such as opening and closing of CPs, rotation of antenna, manipulation and wheel-walking. It's target is the implementation of wheel and manipulator functions that can give service to humans with human-friendly motion. So, this paper presents the definition, the basic theory and experiment results of the RCP mobility system. We confirm a good performance of the RCP mobility system through the experiment results.

본 논문은 감정 교류를 위한 목적으로 가상 캐릭터에서 사용되기 시작하여 현재 로봇에 이르기까지 그 이용 범위를 넓혀가고 있는 스토리텔링이 사용자 친밀성에 미치는 영향과 사용자가 어떻게 엔터테인먼트 로봇과 친밀성을 형성해나가는지, 또 친밀성 요소들은 다양한 스토리텔링에서 서로 어떤 관련성을 가지고 친밀성 형성에 영향을 주는지를 연구 목적으로 삼고 있다. 이를 위해 스토리텔링과 관련된 대화가 가능한 지능형 엔터테인먼트 로봇에 대한 연구를 우선적으로 알아보았으며, 이를 토대로 엔터테인먼트 로봇 중 하나인 애완용 로봇, 아이보(AIBO)가 지니고 있는 스토리텔링을 통해 사용자와 로봇 간 친밀성 형성 및 스토리텔링을 바탕으로 한 친밀성 요소간의 관련성을 알아보았다. 참가자 15명의 설문조사를 바탕으로 실시한 상관관계분석을 통해 사용자와 아이보(AIBO)가 정서적, 오락적, 행동적, 상호공유성에서 인지적, 사회적 친밀성보다 상대적으로 강한 친밀성을 형성하고 있다는 것과 Alexis K. Walker 와 Linda Thompson(1983)을 기본으로 대인관계 측면에서 친밀성에 대해 접근한 이경희(1998), 김혜정(2001), 김미라(2001), 이금남(2001), 송상홍(2004)의 선행 연구를 참조로 분류된 6가지 차원의 친밀성 구성 요소들은 스토리텔링의 형식에 따라 서로 다른 관계성을 형성하고 있다는 것으로 나타났다. 본 논문은 아이보(AIBO)에 쓰이는 스토리텔링이 친밀성 형성에 어떤 영향을 미치는지 또 스토리텔링의 차원에 따라 다르게 반응을 보이는 친밀성 요소들이 서로 어떤 관련성을 맺고 있는지를 살펴본 것에 의의를 둘 수 있다. 스토리텔링에 따라 관련성 정도를 달리하는 친밀성 요소들의 관계를 바탕으로 친밀성 형성에 유용한 스토리텔링의 방향을 제시하는데 의의가 있다.

We evaluate the performance of emotion recognition via speech signals when a plain speaker talks to an entertainment robot. For each frame of a speech utterance, we extract the frame-based features: pitch, energy, formant, band energies, mel frequency cepstral coefficients (MFCCs), and velocity/acceleration of pitch and MFCCs. For discriminative classifiers, a fixed-length utterance-based feature vector is computed from the statistics of the frame-based features. Using a speaker-independent database, we evaluate the performance of two promising classifiers: support vector machine (SVM) and hidden Markov model (HMM). For angry/bored/happy/neutral/sad emotion classification, the SVM and HMM classifiers yield $42.3\%\;and\;40.8\%$ accuracy, respectively. We show that the accuracy is significant compared to the performance by foreign human listeners.

Chatbots have become very popular in our times and are used in several fields. The emergence of chatbots has created a new way of communicating between human and computer interaction. A Chatbot also called a "Chatter Robot," or conversational agent CA is a software application that mimics human conversations in its natural format, which contains textual material and oral communication with artificial intelligence AI techniques. Generally, there are two types of chatbots rule-based and smart machine-based. Over the years, several chatbots designed in many languages for serving various fields such as medicine, entertainment, and education. Unfortunately, in the Arabic chatbots area, little work has been done. In this paper, we developed a beneficial tool (chatBot) in the Arabic language which contributes to educating people about the Prophet's biography providing them with useful information by using Natural Language Processing.
