This study started with the question "Shall we apply the existing record management method to our trivial daily records?" For the general public, we focus on media that thinks more about daily recordings and suggests a better method, suggesting a 'social platform' as a plan, and using the user's visual approach through UX design methodology. The social archive proposed in this study aims to be a 'square' where various people can gather and communicate and share. A space that can record daily life using 'record' as a basic body Purpose It aims to provide the basis for basic research in various fields, and aims to function as a space for communication of various research things such as researchers and researchers, researchers and producers. In order to maintain, focus on the prerequisites of the existing construction, the items to be researched when constructing the daily archive are 'creative methodology to change research items when building a paradigm', 'network with related organizations', 'service plans for persistence', and characteristics of social media. We discussed the possibility of social media as a social archive platform. Finally, while looking at the user experience design process, I designed some features of the social archive and suggested things to do in UX design.

In the semi-autonomous vehicle, before reaching a fully autonomous driving stage, it is imperative for the system to issue a take-over request(TOR) that asks a driver to operate manually in a specific situation. The purpose of this study is to compare whether head-up display(HUD) is a better human-vehicle interaction than head-down display(HUD) in the event of TOR. Upon recognition of TOR in the experiment with a driving simulator, participants were prompted to switch over to manual driving after performing a secondart task, that is, playing a game, while in auto-driving mode. The results show that HUD is superior to HDD in 'ease of use' and 'satisfaction' although there is no significant difference in reaction time and subjective workload. Therefore, designing secondary tasks through HUD during autonomous driving situation improves the user experience of the TOR function. The implication of this study lies in the establishing an empirical case for setting up UX design guidelines for autonomous driving context.

This research aims to suggest a multimodal non-touch gesture interface design to improve the usability of 3D sculpting task. The task and procedure of design sculpting of users were analyzed across multiple circumstances from the physical sculpting to computer software. The optimal body posture, design process, work environment, gesture-task relationship, the combination of natural hand gesture and arm movement of designers were defined. The preliminary non-touch 3D S/W were also observed and natural gesture interaction, visual metaphor of UI and affordance for behavior guide were also designed. The prototype of gesture based 3D sculpting system were developed for validation of intuitiveness and learnability in comparison to the current S/W. The suggested gestures were proved with higher performance as a result in terms of understandability, memorability and error rate. Result of the research showed that the gesture interface design for productivity system should reflect the natural experience of users in previous work domain and provide appropriate visual - behavioral metaphor.

The purpose of this study is to measure the satisfaction level of user experience of athlesure brand community by generation through surveys, and to derive satisfaction level according to consumption taste by generation. As a tool for measuring brand community, a questionnaire written Creating Pleasurable Interfaces Model of Stephen P. Anderson was used and was conducted focusing on women in their 10s-40s, which are the main consumers. As a result of the survey, the community participation rate and satisfaction level are significantly different depending on the consumption tendency of each generation. In addition, focused on task satisfaction was high, but focused on experience satisfaction was relatively low. It was found that there is a need for a plan to improve satisfaction based on experience for revitalization of online and offline communities in the future. Through this study, we expect the use of consumer-centered brand communities and brand communities according to the satisfaction level of consumption demand by generation and consumption preference by demand.

Recently, product design innovation to improve user experience has been perceived as a core element of enterprise competitiveness due to the fierce market competition and decrease of the technological gap between companies, but there is insufficient services to support the product experience evaluation of small and medium-sized companies (SMCs). The aim of this study is to develop a web-based product user experience evaluation and certification system supporting product design practices for SMCs. For system interface design, we conducted systematic functional requirement elicitation methods such as user survey, workflow analysis, user task definition, and function definition. Then main functions, information structure, navigation method, and detailed graphic user interfaces were developed with consideration of user interactions and requirements. In particular, it provides the databases for evaluation efficiency to support the evaluation process above a certain level of performance and efficiency, and knowledge databases to utilize in the evaluation and product design improvement. With help of the developed service platform, It is expected that the service platform would enhance SMCs' product development capability with regard to the user experience evaluation by connecting the consulting firms with SMCs.

Emotional design gets more and more important. However, the systematical approaches to integration of user experience elements in product design have been rarely tried. This study consists of three parts. We extracted affective words fitting to design direction based on trend analysis. Then, user experience elements were matched with affective words. Finally, a prototype system was made to guide designing affective factors in electronic products. In the present study, user experience elements were defined as color, material & finishing, and sound. Through various documents analysis and trend analysis, trend analysis experts and user experience designers extracted 31 affective keywords which could fully reflect current trend. After paired-comparison of selected keywords, 2 sensibility dimensions were obtained by multidimensional scaling. Trend affective keywords could be explained by 2 dimensions of human-centered' vs. 'techno-centered' and 'warm vs. cool'. Next, user experience elements stimuli were matched with each keyword by user direct positioning on the 2 dimensions affective map. Based on the result of the experiment, the prototype system was developed for the product designers. The results of the current study could guide designers to design emotionally satisfactory products.

지금까지 디지털 기기의 진화 과정을 볼 때 오직 기능적 발전만이 추구되고 그것을 사용하는 사용방식에 대한 진지한 고민은 부재하였다. 때문에 디지털 기기가 갖고 있는 버튼 위주의 획일적 사용방식은 사용자보다는 기기 중심의 디자인이 우선시되는 사회적 병리현상을 야기하고 있다. 반면 오랜 기간 인간이 다루어 온 전통적인 아날로그 도구들은 작업의 특성과 작업자의 상황에 맞도록 다양한 사용성을 고려하며 진화되어 왔다. 따라서 본 연구에서는 사용자들에게 익숙한 아날로그적 경험을 디지털 기기의 인터랙션 디자인에 적용시켜 보다 인간 중심적인 디지털 도구를 제안 하고자 한다. 연구의 목표는 다양한 기능이 복합된 대표적 디지털 기기인 휴대폰에 아날로그 경험을 접목시킴으로써 전통적인 도구들과 같이 디지털 기기의 자연스러운 인터랙션 스타일을 디자인하는 것이다. 이를 위하여 한정된 디바이스로 다양한 기능들을 조작해야 하는 모바일 기기에 적합한 아날로그 경험들에 대한 연구가 진행되었고, 기호와 조합으로 이루어진 카드놀이 메타포에서 그 단서를 발견할 수 있었다. 따라서 본 연구는 메타포로 제시한 카드놀이를 하며 일어나는 행위와 경험을 멀티미디어 휴대폰에 접목시켜 새로운 사용 방식을 제안하는 것이다. 예를 들어, 메뉴 선택의 경우 카드를 펼쳐 원하는 카드를 뽑으면 되는데 아래로 펼치면 그 카드의 수직 메뉴가, 옆으로 펼치면 그 카드의 수평 메뉴가 나타난다. 또 메뉴 안의 내용을 찾을 때는 카드를 뒤로 넘겨서 보게 되고 자신만의 개인적인 내용을 보고자 할 때는 카드를 은밀히 보는 듯한 행위를 취하면 된다. 즉 멀티미디어 폰 안의 내용뿐 아니라 사용하는 행위 자체도 하나의 즐거움이 되도록 카드놀이 경험을 새로운 인터랙션 스타일로 개발하여 그 가능성을 연구하였다.

본 연구에서는 현재 시중에 판매되고 있는 네 가지 휴대용 음원재생기를 자극물로 사용하여 제품 속성에 있어서의 차이가 사용자 경험의 여러 요소에 영향을 주는지 여부(가설 1)와 사용자의 정서적 반응이 사용자가 인식한 제품 특성에 의해 영향을 받는지(가설 2) 그리고 제품에 대한 전체적인 판단이 사용자가 인식한 제품 특성과 감성적 반응에 따라 달라지는지(가설 3) 실험을 통해 조사하였다. 실험결과 기능적 특성과 유희적 특성에 대한 인식 정도는 실험 참가자가 사용한 제품에 따라 서로 다르게 나타났으며, 사용자의 정서적 반응과 전체적인 선호도 또한 평가 제품에 따라 서로 다르게 나타남으로서 제품 속성에 의해 영향을 받는 것으로 분석되었다. 이와 함께 사용자 경험을 구성하는 요소들 간의 상호관계도 테스트하였는데, 사용자의 정서적 반응이 주로 제품의 기능적 특성에 따라 달라지는 반면 사용자의 전체적인 판단은 제품의 기능적 특성과 유희적 특성 모두에 의해 영향을 받고 있는 것으로 나타났다. 또 분석결과에서 밝혀진 한 가지 흥미로운 사실은 사용자의 정서적 반응이 전체적인 판단에 아무런 역할도 하지 않는다는 점이다.
