최근 주요 IT 업체의 마케팅 전략은 하드웨어적인 성능 및 가격 위주의 시장전략에서 제품 및 서비스에 대한 사용자의 편의성과 만족도를 극대화시키는 감성 UI(User Interface)/UX(User eXperience)에 바탕을 둔 소비자 감성 지향형 전략으로 이동해 가고 있다. 스마트 시대의 핵심은 감성과 기술의 소통이며, 미래의 정보 서비스는 보고 듣는 것에서 만지고, 느끼고, 기기와 소통하게 함으로써 제품과 서비스의 가치가 결정되는 감성 기반의 서비스가 될 것이다. 감성정보 서비스 기술은 사용자와 기기가 교감하는 디지털 인터페이스를 통해 새로운 형태의 의사 소통 방식과 감성전달 메커니즘으로 소비자의 현재 정서를 인지하고 감정의 정화/승화/억제를 보조하여 보다 사실적이고 실감적인 미디어 소비를 지원할 것이다. 본고에서는 미래 감성 ICT 생태계의 기반이 되는 감성 UX에 대하여 방송 통신망을 바탕으로 한 감성정보 서비스의 현재 모습과 기술동향에 대해 기술한다.

공공 장소에서 주변 상황 정보와 연계하여 각종 정보 및 광고를 인터랙티브하게 제공하는 차세대 디지털 사이니지인 텔레스크린은 구석기 시대의 벽화에서 시작한 상호 의사 소통 방법의 하나이다. 텔레스크린은 초기에 단방향 광고 또는 단순 정보 전달형 서비스를 제공하여 왔으나, 최근에는 카메라, 센서, NFC(Near Field Communication), 스마트 폰 등을 활용하거나, 양방향 UI/UX(User Interface/User eXperience), 얼굴 인식 기술과 연동하여 소비자의 참여를 유도하고 있다. 또한, 사용자의 주변 상황과 사용자의 상태 정보 등을 수집, 분석함으로써 상황인지 기반의 양방향 커뮤니케이션이 가능한 인터랙티브 텔레스크린으로 진화하고 있다. 최근에는 3D 기술과 사람의 반응을 감지하는 인지 기술들이 지속적으로 발전하고 있기에, 멀지 않은 미래에는 사용자의 감성에 반응하는 텔레스크린 서비스가 제공될 것으로 기대된다[1]. 그리하여, 사용자가 인식하지 못하는 사이에 주변 상황과 더불어 사용자의 감성에 기반하여 가장 효과가 높을 것으로 기대되는 맞춤형 정보에 자연스럽게 노출되게 될 것이다.

최근 소비자가 컴퓨터는 물론 각종 전자기기를 구매하는데 있어 UI(User Interface) 및 UX(User eXperience)가 매우 중요한 요소로 자리 매김하고 있다. 터치스크린이나 각종 센서들이 탑재되고 있는 전자기기에서 볼 수 있듯이 HW의 눈부신 발전과 함께 더불어 UI의 다양성도 확대 되고 있다. 본 논문은 이러한 기대에 부응하기 위해 게임에서 많이 사용되는 물리엔진을 UI에 적용시켜 보았다. 여러 물리엔진들 중에 본 연구에 적합한 Box2D를 채택하여 UI에서 응용 할 수 있는 10가지 모듈을 제시하였으며 활용할 수 있는 예도 제안하였다.

What difference does the metaverse experience have from the real world? This study investigated the effect of space size and dialogue topic on metaverse user experience. The results from a 3(space size: reality vs. metaverse in an open room vs. metaverse in a closed room) x 2(dialogue topic: positive vs. negative) mixed factorial design experiment (N = 75) revealed statistically significant effects of space on responsiveness, and dialogue topic on closeness. This result implies that designing metaverse for non-immersive devices should include careful considerations regarding the characteristics of the user's real space.

This study aims to improve User eXperience (UX) of the diagnostic-supplement learning system for Basic academic skills which has been utilized by teachers nationwide since 2015 in order to provide a consistent and systematic support on students' basic academic skills in K-12 school contexts. To achieve the research objective, usability evaluations such as basic questionnaire about UX/UI of the system according to user types, user testing, in-depth interview, expert heuristics were conducted. In addition, user-centered system was suggested through developing and iteratively evaluating the prototypes based on the user requirements drawn from the findings of such quantitative and qualitative usability evaluations. This study has an implication in suggesting the user-friendly design through the UX/UI improvements of the diagnostic-supplement learning system for Basic academic skills.

TV businesses that have brought a competitive structure in terms of price, definition, product design for a long time now are bringing User eXperience (UX) into relief as DTVs come to support broadcast information-related services such as various broadcast channels and Electronic Program Guide(EPG), etc., and playing of multimedia contents like music/videos, etc. This study worked on an evaluation by developing a UI to control easily the various and complex broadcast contents or multimedia contents provided by DTVs. The UI Design for new DTVs was developed based on Function, Flow and Form in the concept of Single ABC (Access, Browser and Control), and the usability test of the developed UI concept along with the UIs of the major DTV products, was done for Channel Managers and the multimedia browsers for 32 users of DTVs in the U.K./U.S., respectively. As a result of the usability test, the new concept of Channel Manager was evaluated high both in the U.K./U.S, while the multimedia browser was evaluated low in the U.S., relatively.

As growing interest in Human-Computer Interaction(HCI), research on HCI has been actively conducted. Also with that, research on Natural User Interface/Natural User eXperience(NUI/NUX) that uses user's gesture and voice has been actively conducted. In case of NUI/NUX, it needs recognition algorithm such as gesture recognition or voice recognition. However these recognition algorithms have weakness because their implementation is complex and a lot of time are needed in training because they have to go through steps including preprocessing, normalization, feature extraction. Recently, Kinect is launched by Microsoft as NUI/NUX development tool which attracts people's attention, and studies using Kinect has been conducted. The authors of this paper implemented hand-mouse interface with outstanding intuitiveness using the physical features of a user in a previous study. However, there are weaknesses such as unnatural movement of mouse and low accuracy of mouse functions. In this study, we designed and implemented a hand mouse interface which introduce a new concept called 'Virtual monitor' extracting user's physical features through Kinect in real-time. Virtual monitor means virtual space that can be controlled by hand mouse. It is possible that the coordinate on virtual monitor is accurately mapped onto the coordinate on real monitor. Hand-mouse interface based on virtual monitor concept maintains outstanding intuitiveness that is strength of the previous study and enhance accuracy of mouse functions. Further, we increased accuracy of the interface by recognizing user's unnecessary actions using his concentration indicator from his encephalogram(EEG) data. In order to evaluate intuitiveness and accuracy of the interface, we experimented it for 50 people from 10s to 50s. As the result of intuitiveness experiment, 84% of subjects learned how to use it within 1 minute. Also, as the result of accuracy experiment, accuracy of mouse functions (drag(80.4%), click(80%), double-click(76.7%)) is shown. The intuitiveness and accuracy of the proposed hand-mouse interface is checked through experiment, this is expected to be a good example of the interface for controlling the system by hand in the future.

Currently, various technological models and services are emerging because of the development of information and communication technology and the convergence of industries. The ICT car field is expanding because of technological convergence in the automobile industry. However, ICT convergence services are still being developed based solely on technology; characterization of users and their needs is lacking. Therefore, two types of ICT car services that apply human-centered design processes are developed in this study. These processes create services and models while considering the quality and functions of products based on users (instead of technology) when developing products or services. Usability evaluation was performed on the developed services; a human-centered design process was applied to the results to confirm that the derived services resulted in high satisfaction. In the future, these research results will provide useful applications when developing ICT car services and strategies.
