다양한 정보기기들이 출현함에 따라 UI가 제품성공의 중요한 요인으로 부각되고 있다. 이러한 중요성을 인식하고 Microsoft, Nokia, HP, Motorola 등 해외 선진기업들은 UI 연구에 주력해 오고 있다. 국내 기업들도 2000년대부터 본격적으로 기업 내 UI팀을 구성하기 시작하여 점점 그 규모와 역할을 확대해 나가고 있지만, 개발시간의 촉박함, 체계적인 방법론에 대한 인식 부족, 전문인력부족 등으로 인해 UI업무가 효율적으로 진행되지 못하고 있다. 선진기업과 경쟁하기 위해서는 사용자 경험 측면에 대한 투자가 시급하며, 국내 UI전문가의 역할이 크게 요구되고 있는 시점이다. 따라서 기업 내 UI업무의 현주소를 파악하고 통합적인 고객체험 디자인을 목표로 하는 UI팀의 발전방향을 모색하고, 비전을 제시하는 것을 연구의 목적으로 삼는다. 본 연구의 방법으로는 문헌조사와 선행연구를 통해 UI, UX의 개념과 UI관련 조직의 구성과 역할을 살펴보고, 국내 모바일 및 전자제품 제조사, 유무선 인터넷을 기반으로 하는 컨텐츠 서비스 업체의 UI실무자를 대상으로 한 인터뷰와 설문조사를 통해 현재 기업 내 UI팀의 현황(조직구성, 업무의 범위 및 프로세스, 조직 내에서의 위상 등)을 분석하였다. 그 결과 다음과 같은 문제점들이 도출되었다. 첫째 조직구조상의 문제점, 둘째 업무 프로세스상의 문제점, 셋째 전문인력의 부족 등이다. 본 연구를 통해 기업 내 UI팀의 역할과 위상이 그 중요도에 비해 미약한 것으로 나타났다. 따라서 향후 통합적인 UX디자인을 접목한 미래 지향적 UI팀으로써 전체 프로세스 과정에 비전을 제시하기 위해서는 다양한 분야의 전문가들로 구성된 독립적 UI팀 구성이 이루어져야 한다. 또한 기획, 디자인, 개발 등 타 부서와의 보다 적극적인 업무교류를 통해 사용자의 입장을 대변하는 역할을 해야 한다.

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.

In this paper, we design a smart phone UX/UI and a tap pattern recognition algorithm that can recognize tap patterns from a tapping user's fingers on the screen, and implement an application that provides user-customizable smart phones's services from the tap patterns. A user can generate a pattern by tapping the input pad several times and register it by using a smart phone's favorite program. More specifically, when the user inputs a tap pattern on the input pad, the proposed application searches a stored similar tap pattern and can run a service registered on it by measuring tap pattern similarity. Our experimental results show that the proposed method helps to guarantee the higher recognition rate and shorter input time for a variety of tap patterns.

The game industry using Smart phones and related market is rapidly growing every year and a graphical view of the game fun and games player is in a diverse environment improvement. Game visuals in the design of the application of the user's perspective, very simple tricks, unlike such as the game's environment is pc, but more sophisticated and to improve the quality of the game, planning is required. Ranking the top rankings, game downloads this study, therefore, has recently structured questionnaire based on the case in existing research conducted a survey. The surveyed more than 200 million people downloaded the Onmyoji game users in China was limited to the preferences of each gui survey analyzed. Preference shown in graphic identify success factors should be improved to lighting of the basic elements of design / ux ui and applications should be taken into account when designing the game. A Study on Design Factors for research purposes. The results verification the importance of visual elements, information elements, manipulation, and rapid response.

Persons with low vision impairment refers to visual and visual impairments that can not be remedied by medical or optical methods due to inherited or acquired eye disease. People with low vision impairments account for more than 240 million people in the world and have only a few remaining eyesight. We will discuss the improvement of information accessibility of low visually impaired people and future research methods through research on Web UI/UX in mobile web environment for low visibility handicapped in the environment where information can be accessed through existing screen reader (TTS) and screen enlargement function.

As concerns about users' privacy infringement on Online Behavioral Advertising(OBA) increase, regulators are taking measures such as drawing up guidelines for OBAs, and websites provide OBA guidance in compliance with such guidelines. As a result of reviewing the status of providing OBA guidance on websites, access to OBA guidance pages was rather complicated. In order to analyze the issue from the UI/UX perspective, following the "Guidelines for Privacy in Online Behavioral Advertising" applied to all types of OBA transmitted on websites, this study aims to structuralize a navigation of page movement from two starting points, 1) Main Page, 2) The page where OBA is delivered, to OBA guidance pages. Also, with understanding the problems found in the access and navigation of OBA guidance pages by analyzing features found during the page navigation, such as hyperlinks containing keywords, and movement pages.

Recently, wearable devices have gained popularity with familiar form factors and designs of eye-wear and watch to satisfy wearers' various preferences. Since UI/UX of smartphones can not be applied directly on smaller wearable devices, text entry on wearable devices is still problematic. In this paper, we first identify UI/UX problems of existing input methods and propose a new input method for wearable devices specifically targeting smartwatch platforms. We design and implement an efficient text entry method for wearable devices using trackball sensor and evaluate its performance and usability.

With the recent advance in smartphones, users are allowed to use mobile applications anytime anywhere, and change their way to interact with smart environment and people. As a result, the need for developing context-aware applications on smartphones has a great attention from users and developers. This paper proposes a context-aware framework for supporting UI/UX of smartphones. The proposed framework collects a wide range of sensory data from smartphones and allows developers to analyze and model context models for their desired apps. In addition, it also supports real-time inference within the apps to make them to adapt to context. In order to show effectiveness of the proposed framework, we introduce two smartphone apps: context-aware home screen and automatic detection of smartphone problem use. Therefore, we expect that the proposed framework will help developers easily implement their apps with respect to context-awareness.

고령 사회의 급격한 확대로 인해 스마트 기기를 잘 다루는 스마트 시니어들의 문화향유가 급증하고 있다. 시니어 세대는 인지 및 운동능력이 급격히 감퇴하는 시기로, 콘텐츠를 활용한 원활한 문화향유를 위해서는 감퇴하는 능력에 대한 개인의 능력을 파악하여 콘텐츠 제작자들에게 알맞은 가이드라인을 제공해줄 필요가 있다. 본 연구는 시니어의 인지 및 운동능력 측정을 통하여 웹콘텐츠에 사용되는 UI/UX 컴포넌트를 매핑하고, 컴퓨터 과학에 전문적인 지식이 없는 개발자 또는 콘텐츠 제작자들에게 시니어를 잘 이해할 수 있도록 하는 시각화 방법을 제안한다.
