기술격차 감소로 인해 제품 차별화를 위한 인지 감성적 제품설계가 중요해지고 있다. 성별, 연령 등 다양한 사용자이 느끼는 감각(시각, 청각, 촉각 등), 인지(주의력, 기억력 등), 감성(심미성, 기능성 등)을 고려하기 위한 데이터베이스와 제품설계 가이드라인이 필요하다. 여러 실험으로부터 도출된 사용자 특성정보는 제품의 설계 및 평가 시 주요한 지표로 사용되고 있으며, 이를 저장할 통합적 인지 감성 데이터베이스를 구축하는 것이 필요하다. 본 연구에서는 인지 감성적 제품설계 지원을 위한 사용자 특성정보 메타데이터를 설계하고 프로토 타입 시스템으로 구축하였다. 감각, 인지, 감성에 관련된 기존 문헌들을 조사하고 분류하여 인지, 감성 유형별로 반영할 수 있도록 설계하였다. 제품설계/평가에 필요한 다양한 사용자 특성정보를 RDF 형식의 설계하였고, 설계된 메타데이터에 따라 인지, 감성에 관련된 사용자 특성정보를 저장할 수 있도록 프로토 타입 시스템을 구축하였다.

Some serious neck diseases are closely related to negative emotion. In order to explain the etiology deeply, we assumed that upper trapezius is innervated by emotional motor system (EMS), a special motor system. And then we developed an upper trapezius-specific surface electromyography acquisition system concerned with its special innervation to prove our assumption. Through a targeted experiment, we found that upper trapezius is indeed innervated by EMS.

Recently, there are many researches have been studying for analyzing user interests and emotions based on users profiles and diverse information from Social Network Services (SNSs) due to their popularities. However, most of traditional researches are focusing on their researches based on single resource such as text, image, hash tag, and more, in order to obtain what user emotions are. Hence, this paper propose a method for obtaining user emotional information by analyzing texts and images both from Instagram which is one of the well-known image based SNSs. In order to extract emotional information from given images, we firstly apply GRAB-CUT algorithm to retrieve objects from given images. These retrieved objects will be regenerated by their representative colors, and compared with emotional vocabulary table for extracting which vocabularies are the most appropriate for the given images. Afterward, we will extract emotional vocabularies from text information in the comments for the given images, based on frequencies of adjective words. Finally, we will measure WUP similarities between adjective words and emotional words which extracted from the previous step. We believe that it is possible to obtain more precise user emotional information if we analyzed images and texts both time.

Objective: The aim of this study is to investigate haptic perception related researches into three perspectives: cutaneous & proprioceptive sensations, active & passive touch, and cognition & emotion, then to identify issues for implementing haptic interactions. Background: Although haptic technologies had improved and become practical, more research on the method of application is still needed to actualize the multimodal interaction technology. Systematical approached to explore haptic perception is required to understand emotional experience and social message, as well as tactile feedback. Method: Content analysis were conducted to analyze trend in haptic related research. Changes in issues and topics were investigated using sensational dimensions and the different contents delivered via tactile perception. Result: The found research opportunities were haptic perception in various body segments and emotion related proprioceptive sensation. Conclusion: Once the mechanism of how users perceives haptic stimuli would help to develop effective haptic interactrion and this study provide insights of what to focus for the future of haptic interaction. Application: This research is expected to provide presence, and emotional response applied by haptic perception to fields such as human-robot, human-device, and telecommunication interaction.

최근 스마트폰 환경에서 제공되는 수많은 서비스들은 일률적으로 소비자에게 단방향으로 제공되던 예전과 달리 사용자마다 개인화된 서비스 제공을 통해, 더욱 효율적으로 서비스를 제공하려는 시도들이 이루어지고 있다. 그 중에서 감정인식을 이용한 연구는 사용자에게 최적화된 개인화 서비스 제공을 위해 사용자의 감정을 인식하여 사용자가 느끼는 감정에 맞는 서비스를 제공함으로써 보다 몰입감을 느낄 수 있도록 하여 결과적으로 특정 서비스의 이용을 유도하도록 할 수 있다. 본 논문에서는 사용자 선호도와 컨텍스트 정보를 활용하여 사용자의 감정을 추출하고 이를 음성기반 감정인식과 융합하여 그 정확도를 높이고 실제서비스에서 활용할 수 있는 시스템 설계를 제안한다. 제안하는 시스템은 사용자 선호도와 컨텍스트 인식으로 감정을 판단했을 경우의 오류를 음성을 통한 감정인식으로 보완하며, 사용자가 감정인식 시스템을 활용하기 위한 비용을 최소화한다. 제안하는 시스템은 스마트폰에서 사용자 감정을 이용한 애플리케이션이나 추천서비스 등에서 활용이 가능하다.

Hand gesture is the most common tool used to interact with and control various electronic devices. In this paper, we propose a novel hand gesture recognition method using fuzzy logic based classification with a new type of sensor array. In some cases, feature patterns of hand gesture signals cannot be uniquely distinguished and recognized when people perform the same gesture in different ways. Moreover, differences in the hand shape and skeletal articulation of the arm influence to the process. Manifold features were extracted, and efficient features, which make gestures distinguishable, were selected. However, there exist similar feature patterns across different hand gestures, and fuzzy logic is applied to classify them. Fuzzy rules are defined based on the many feature patterns of the input signal. An adaptive neural fuzzy inference system was used to generate fuzzy rules automatically for classifying hand gestures using low number of feature patterns as input. In addition, emotion expression was conducted after the hand gesture recognition for resultant human-robot interaction. Our proposed method was tested with many hand gesture datasets and validated with different evaluation metrics. Experimental results show that our method detects more hand gestures as compared to the other existing methods with robust hand gesture recognition and corresponding emotion expressions, in real time.

Recently, deep neural networks (DNNs) are actively used for action control so that an autonomous system, such as the robot, can perform human-like behaviors and operations. Unlike recognition tasks, the real-time operation is essential in action control, and it is too slow to use remote learning on a server communicating through a network. New learning techniques, such as reinforcement learning (RL), are needed to determine and select the correct robot behavior locally. In this paper, we propose an energy-efficient DNN processor with a LUT-based processing engine and near-zero skipper. A CNN-based facial emotion recognition and an RNN-based emotional dialogue generation model is integrated for natural HRI system and tested with the proposed processor. It supports 1b to 16b variable weight bit precision with and 57.6% and 28.5% lower energy consumption than conventional MAC arithmetic units for 1b and 16b weight precision. Also, the near-zero skipper reduces 36% of MAC operation and consumes 28% lower energy consumption for facial emotion recognition tasks. Implemented in 65nm CMOS process, the proposed processor occupies 1784×1784 um2 areas and dissipates 0.28 mW and 34.4 mW at 1fps and 30fps facial emotion recognition tasks.
