In the mobile-first era, plenty of mobile apps have been created so that the number of apps owned in a smartphone have been increasing as well. However, users spend most of time with only a few apps and the rest of apps are just kept in their smartphones for future usage. Thus, in order to help users find the apps quickly it is important to study how users arrange apps in a mobile phone screen and find an app. In the literature, we extracted 5 user types to organize mobile apps. We further conducted user survey with 30 subjects and finalized major 3 user types categorized by relatedness(A), aesthetic(B), and external concepts(C). We found that most of subjects took less than 2 minutes when finding frequently-used-apps. However we identified difference in times taken to find a barely-used-apps across three user types; while A type users turns out to be the most effective in finding barely-used-apps, the B type uses tend to be the least effective among three types. For the A type users, an app's name is more important than an icon image because they tend to guess the functionality from the name of the app. The B type users use the color of app icon to find the app in the smartphone. For the C type users who tend to remain the original position of an app when first downloading it in the smartphone, the visibility of an app icon is important to catch users' eyes while they scan a page. The results of this study is expected to be useful for UX designers who improve the usability of app icon usage considering the user types.

The development of science was crucial to recent advancements in design such as digital contents, UI, GUI, UX design. Not until the DOS evolved into Windows OS were many kinds of digital media design created, namely due to the invention of the computer mouse. A necessary element of mobile phones and Window OS is icons, since icons act as visual symbols, touch buttons and gateways into software content. Icons have undergone many stages of development simultaneously with developments in digital science. We can observe changes in mobile icon design from Skeuomorphism Design to Minimalism to Flat Design. These changes were caused by macro-level trends in design across all other industries. Apple iPhone's Skeuomorphism Design of 2013 evolved into IOS7's Minimalism and Flat Design of 2014. In the mobile world, flat design will again create big changes in design. This research aims to contribute to basic research data of GUI design that are used by creators of mobile apps to understand and anticipate future trends.

본 작품은 학생들의 캡스톤디자인 작품이다. 현대인들은 자신의 감정을 특정한 문자를 통해서 상대방에게 전달하고자 한다. 하지만, 현재 모바일 폰의 문자 메시지는 텍스트 위주의 평범한 문자를 보내기 때문에 자신의 감정을 표현하기에는 불충분하다. 따라서 본 작품은 텍스트 기반의 문자 서비스를 탈피하여 편지지와 아이콘을 활용하여 지산의 감정을 표현할 수 있는 모바일 편지 서비스 앱이다. 본 작품은 바쁜 현대인의 특성상, 자신의 필체가 악필일 경우가 많아 꺼려하고 있다. 당장 자신의 글씨를 고치기에는 시간이 부족한 경우도 많고 동시다발적으로 메시지를 전하고 싶어 하는 사람들에게 항상 지니고 있는 스마트폰으로 자신의 진심이 느껴지고 특별한 편지를 제작 하여 전송을 하고자 개발하였다.

Smartphone used to be an it item for only business people and early adaptors. However, the public interest towards Smartphone has been rapidly increased and now is spreading to the everyday life in general people. Variety of applications are introduced and registered in a day, but there are not enough apps with simple and useable interface. This is because that the applications are developed only in a view from developer and designer to match the splendor design and technical skills of apps not concerning the users. Therefore this study will analyze the value in use and design trend of registered apps in apps store to recognize the importance in use and also to discuss about a plan to apply this into the apps more effectively. In order to improve the mobile app usability, this study suggest that using intuitional icon, designing easy to use app navigation. This will lead to produce clear instruction for app developers and designers with more reliable effects in the future of Smartphone world.

In this study, in order to provide an app with improved usability to users in the trend of gradually increasing the number of users of music streaming services, usability tests were conducted by conducting interviews before and after the execution of the screen test technique and the performance measurement method and contextual. Usability test was conducted using the Inquiry method. Usability tests were conducted by one user each from their teens to their 50s, and were conducted on Melon, YouTube Music, Genie, and FLO apps with many service users. As a result of the usability test, the icon does not sufficiently represent the function and is not recognized as an interactive button, which is overlooked by the user, the problem that the user does not recognize due to lack of visual effect when the function is activated, The problem was derived. In this regard, suggestions for improving the user screen, such as intuitively changing the icon for each app, adding a visual effect of the screen when the function is activated, and adjusting the position so that the function has continuity, were presented along with the visual data.

In the context of the number of Tablet PC users which increases rapidly, online shopping application has also been a corresponding rapid development. However, as a practical matter, the differences among the consumers' ability will affect the purchase of application for the realization of user needs. Therefore, shopping application in the GUI design to improve consumers use needs to be improved to meet the demands of different users. In view of this problem, this paper has carried on the related research on the GUI design of Tablet PC application, and fully considers the visualization image elements of information transmission, then analyzed the top five shopping application in Chinese market via three visual elements - icon, label and color. In addition, it conducted a questionnaire which based on the object of Tablet PC shopping application Chinese users. Consequently, what obtained is, based on the survey findings, the GUI design proposal which reasonable reflects the shopping application with functionality and designability. Through the research results of this paper, we can get the conclusion that the three kinds of visual GUI elements-icon, label and color- have the influence on the user's usability. In addition, this study can be expected as a reference in the shopping software GUI design.
