최근 들어 빅데이터 기반의 추천 방식과 개인화 시스템을 활용하여 맞춤형 콘텐츠를 추천해주는 서비스가 주목받고 있다. 이는 단순히 OTT 서비스뿐만 아니라 상품추천이나 음악 추천, 친구 추천, 뉴스 추천 등 여러 분야에서도 널리 사용 중이다. 본 연구는 OTT 서비스의 맞춤형 콘텐츠를 지속해서 이용하는 경우 정보 탐색 과정의 사용 경험과 이용만족도에 대해 알아보고자 시작되었다. OTT 서비스 중 사용자가 가장 많고 콘텐츠 추천 기능이 강점인 넷플릭스와 왓챠플레이를 중심으로 사용자 인터뷰를 진행하여 사용자들의 추천 기능 이용 패턴을 파악하고 그 과정에서의 특이사항이나 어려움을 파악하려 하였다. 이를 바탕으로 콘텐츠 추천 및 탐색 과정의 UX를 개선할 수 있는 방안을 제시하고자 하였다.

최근 들어 차량은 단순히 이동을 위한 수단에서 벗어나 정보통신 기술과 융합되면서 콘텐츠를 소비하는 공간의 성격을 가져가고 있다. 자동차도 하나의 컴퓨터처럼 기능하게 되면서 차량 인포테인먼트의 역할이 차량 사용 경험에 중요한 요소로 자리 잡게 되었다. 그러나 교통수단이라는 특수한 환경임에도 불구하고 다른 환경에서 콘텐츠를 제공하는 형식과 차별화 없이 차량용 디스플레이에 맞춰 UI만 변경된 형태로 서비스가 제공되는 모습을 발견할 수 있다. 이에 본 연구는 문헌 조사 및 사용자 인터뷰를 통해 현재 차량 인포테인먼트 사용 행태와 보완점을 발견하여 개선 방향을 모색하고자 하였다. 사용자들이 차량 내에서 각기 다른 이용 패턴을 반복해서 실행하는 과정에서 인포테인먼트의 개인화 서비스에 대한 니즈가 있음을 확인하였고, 개인화 서비스를 통해 맞춤형 정보를 제공함으로써 새로운 가치를 만들어 낼 수 있음을 제시하고자 하였다.

With the active usage of digital media, the importance of and the interest in User Interface (UI)/User Experience (UX) have been increasing. This study proposes the development of design evaluation model to utilize the quality analysis model as a basis if there were to be a development of mobile education application. Main factors of the design evaluation model, which is based on User Value analysis, influence users' attitudes and intentions in continuing their uses of a mobile education application. The employment of the design evaluation factors onto the existing agile method's development stage, therefore, would provide an optimal UX environment for the application. This application not only will increase the satisfactions of consumers, but also will have positive impacts on their intentions in continuing their uses of a mobile education application.

UX 디자인을 하는데 있어서 제품이나 서비스를 대하는 사용자의 컨텍스트(Context)를 파악하는 것은 매우 중요한 일이다. 다양한 사용자 리서치 방법들 가운데 사용자의 컨텍스트를 파악하기 위한 방법으로는 Contextual Inquiry, 사용자 관찰, Cultural Probes, Contextmapping등이 있는데, 사용자의 컨텍스트는 매우 역동적이고 상황에 따라 다양하게 표현될 수 있으므로 이러한 방법들을 적절하게 조합하여 사용하는 것 이 필요하다. 이렇게 파악된 사용자의 행동패턴과 컨텍스트 요소를 반영하여 UX모델을 만드는데, 사용자의 목표와 사용행태를 기술하는 퍼소나(Persona)가 대표적인 방법이다, 또한 퍼소나를 기반으로 제품이나 서비스에 대한 아이디어와 디자인을 이끌어 내는데 활용하는 '사용자 시나리오(User Scenario)'는 미래의 혁신적인 사용자 경험을 제안하기 위한 유용한 방법이다.

The objectives of this research is to compare UX elements influencing the satisfaction of users in Korea and North America according to product types of mobile commerce services, to determine UX INDEX suitable for each type of service, and to derive positively influencing UI factors through analyzing the relationship between UX INDEX and UX design detail factors. This research showed that there was difference in perceived reliability according to selling product types and there was difference in both perceived usefulness and reliability according to users in Korea and North America. Also, this research found out that, in analysis of relationship between UX INDEX and UX design detail factors, UI factors to understand a service structure generally showed close relationship but factors such as troubleshooting and help showed difference between users in Korea and users in North America.

In recent days, when the development in smartphones has made it common to operate objects by using them, this study aimed to present a guideline for the UI/UX designs for applications which are necessary for operating various objects through the wireless communication technology. To suggest the application guideline, existing object control application case studies were analyzed, and based on this investigation the object control application UI/UX design guidelines were proposed. This study classified the types of wireless connections used by smartphones (LTE, Wi-Fi, Bluetooth, NCF, RFID) and analyzed the necessary design factors for operating objects by each type. Based on such analysis, this study presented the design sequence, factors, and methods for the UI/UX guidelines of applications. First, the method of connection was selected; second, the control device was selected. This new direction for designing smartphone applications for operating objects will likely help systemize the design process and enable the user to operate the object more intuitively. In future research, case studies will be designed applying the guidelines suggested from this study.

The development of bio-sensing technology made it easy to collect various biometric information that was only available in large medical devices. The miniaturization of sensors makes it simple to carry out various health checkups that It did in person to the hospital by improving the portability of diagnostic devices. It is able to combine sensors into portable devices such as Smartphones, apply advanced Internet of Things (IOT) technology, and create new form factors for medical devices such as ultra-small modules that can be inserted or attached to their bodies. The results can be checked immediately through portable information devices such as smart phones. Although commercialization is still slow in Korea, new technologies are being applied in various ways in countries such as the United States that have granted remote medical services. Medical demand, supply and cost in South Korea are growing ahead of a super-aged society. Under these circumstances, attention is focusing on whether smart healthcare, a new concept, can complement the existing medical system. This study identifies the technology trends associated with smart health care and categorizes various healthcare products in the UX design aspects. In addition, the UX design approach and guidelines for applying smart healthcare technologies to the elderly, the intended users, are presented. This research will provide a reference to a new social issue, the UX-design approach to solving the problems of the aged society.

The purpose of this study is to propose the features of autonomous DRT UX design based on level 5 autonomous vehicle applicable in 2027. As the scope of the study, the system focused on the interaction between the elderly and the in/outside of the vehicle, and the level 5 autonomous vehicle was the subject of the study. As of 2021, the targets for application were set from 60s to 90s. This study is different from previous studies in that it is a study on the features of autonomous DRT UX design that derives practical insights through direct communication with the elderly. As a research method, autonomous vehicle and DRT were theoretically considered through literature research, and based on this, cases of autonomous vehicle and DRT were analyzed. As a case study, generalization was conducted through interviews with the elderly, test-drive of autonomous vehicle, video production, survey, and VR test-drive of autonomous vehicle for the elderly. Ten features of autonomous DRT UX design were derived through focus group interview(FGI), and the derived features were classified into reservation, get on, input, driving, emergency, and get off. Through this study, I hope that it will contribute to improving mobility of the elderly and further accelerate the practical use of autonomous DRT.
