This study suggests user-friendly design fiction method applying user-centered design process. Design fiction is a method that predicts futures from design perspective with critical discourses and physical representation. It has been regarded importantly in HCI and interaction design realms as aesthetical and experiential approaches, yet not firmly established. Especially, it has not been considered from user-centered perspective which considers users and related problems. Anticipatory design based on current problems which predicts futures and defines design-oriented scenario is becoming significant. Therefore, this study regards design fiction method in relation to prior design also should consider user-centered perspective, not just experimental approaches. In this regards, this study tries to apply user-centered process, specifically affordances which lead more intuitive and direct impact on users into conventional design fiction process. This study led junior students in visual communication major into design fiction process with specific topics and the Design with Intent Toolkit amongst practices of creating affordances so as to develop new design fiction process with its diverse outcomes. Throughout the process, this study aims to suggest alternative user-friendly design fiction method beyond its critical and experiential approaches.

Recently, traditional impression has been rapidly replaced by digital impression using intraoral scanning. There are more than 7 types of intraoral scanners available in the dental market. It is difficult to make effective strategic choices due to a lack of standards and guidelines for optimal intraoral scanning devices. So far, little has been reported about evaluating the ergonomic aspect of these scanners. This literature review compares current intraoral scanning systems based on different types of handles and suggests the most comfortable, user-friendly intraoral scanners from an ergonomic standpoint.

본 논문은 AI 기술을 활용하여 웹 디자인 및 개발 과정에서 생산성과 비용 측면에서 발생하는 문제점을 해결하기 위한 솔루션을 제안하고 있다. ChatGPT와 같은 대규모 언어 모델을 기반으로 사용자가 원하는 웹사이트 유형과 데이터를 입력하면, AI가 적절한 웹 템플릿을 제시하고, 해당 템플릿을 기반으로 동적인 웹사이트를 자동으로 제작하는 방식으로 작동한다. 이를 통해 개발자는 웹사이트 디자인 및 레이아웃 개발에 소요되는 시간과 비용을 절감할 수 있다. 이러한 방식은 웹사이트를 더 사용자 친화적이고 참여도 높은 것으로 만들어, 고객 유치와 이타적 상호작용을 유도하며, 회사나 조직의 성공에 기여할 수 있다.

A new style keyboard which is user friendly and can be used efficiently in a small area is proposed in this paper. The most pre-existing keyboards were using the style of selecting a key among the arranged keys even the formats of key arrangement and the ways of using them were different. A new style of information input device called Dynamic Keyboard(DynaKey) is designed in this paper. Dynakey is a useful information input device which can be used efficiently for a mobile device with small display and for handicapped persons who has difficulties of selecting precise positions.

본 연구에서는 퍼블릭 블록체인 기술을 적용하여 탈중앙화된 식별 정보(DID) 어플리케이션을 개발하였다. 기존의 컨소시엄 블록체인을 사용한 DID는 일부 참가자들 간의 신뢰를 기반으로 동작하여 특정 그룹의 중앙화된 통제 가능성으로 인해 보안 문제가 발생하는데, 이를 극복하기 위해 퍼블릭 블록체인을 도입하여 안전하고 투명한 디지털 식별 체계를 제시한다. 또한, 본 연구에서는 웹앱 형태의 DID 어플리케이션을 사용자 친화적이고 직관적인 디자인으로 구현하여 사용자들이 쉽게 식별 정보를 관리하고 교환할 수 있도록 하였다. 더불어 안전한 키 관리 및 전자 서명 기술을 적용하여 사용자들은 자신의 식별 정보를 완전히 통제할 수 있으며, 이를 통해 탈중앙화된 신뢰 모델을 체험할 수 있다.

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.

Smart City is a future-oriented city that provides users with desired services through various devices anytime and anywhere using Information and Communication Technologies (ICTs). In order to provide the smart city service desired by the user, the user-oriented design concept should be based on above all. The design and development process must be based on the opinions and needs of everyone involved and needs to ideally reflect all user information and feedback, including users, designers and stakeholders at all levels. Participatory design approaches can be seen as an attempt to better understand and engage real users, and they are essential and important to create more appropriate and user-friendly smart-city services. This study has recognized the importance of developing a smart city service from the viewpoint of user - centered design and examined the methodology of design thinking and service design process for smart city service development. User - centered design concept model for smart city service design was designed, and serviceability case developed based on concept model was verified.

Recently the studies on user-centered design and form-development have become issues of general interest as the key methods for successful design. For form analysis on user it is important needs that an integrated approach of existing methods and development of expert tool for designer. Moreover analysis methods and tools have to meet with the designers needs of visual result, clear direction, concrete formative factor, user's emotional response and designer-friendly interface. This study proposed the main concepts of form analysis tool based on the user's emotional response ; integrated management, variables set-up, visual result of analysis, in-depth analysis with data mining and correlation, and reinforcement of user-centered analysis. Specific analysis tool consists of 5 functions: Project Management, Analysis Frame Set-up, Data Input-output, Basic Analysis, and In-depth Analysis. The feasibility of proposed tool was verified by a case study of mobile phone design in under-graduate class.
