Mobile learning content implementing is IT tourism convergence study that IT convergence IT and tourism. Learning to increase the effectiveness of mobile learning content for each learning module, It proposed u-smart tourist information 2.0 systems. Mobile learning content, implementation is u-smart tourist information 2.0 can use the system. Convergence/integration of design patterns and XML is so interesting to students. This is the maximum benefit which is taught classes for each learning module divided into learning the Design Pattern NCS. As a result, the learner. In particular, attendance has come out better the effect of learning and improved. Another advantage is tourism, information content information quality mobile learning content for and construct a tourist information content that you can do in real time. Also, mobile learning content, implementation in the next NCS expected to use a lot of help in learning. This study is the result of increased learning the analysis of the lessons learned. Implement mobile learning content gives fun and interesting to the learner to ten design process using the u-Smart Tourist Information class 2.0.

The study aims to suggests mobile application service that helps to reduce physical and mental suffering after surgery for breast cancer patients constantly increasing. At first, I analyze literature research to understand the breast cancer and similar services for achieving study purposes. After I finally design a mobile application that offers to customed one-to-one specialist coaching service focused on post-treatment management by using a double diamond design process model. In detail, first, I analyze the current program and comprehend user needs through interviews with the person such as breast patient, protector, nurse, salesperson in cancer center. Second, I specify the entire scenario, concept and keyword based on the persona and the customer journey map representing user. Third, I propose the mobile application for the ultimate goal by producing prototype to effectively communicate with specific functional descriptions. I hope this service will improve the quality of their lives.

This study is for the use of color recommendation system for the color combination of mobile application. For this study, color combination methods of a material design color system that recommends harmonized colors automatically and of a mobile web application were applied to a mobile application design and a color combination experiment was carried out. Then for a survey on the experiment using the two methods, color combinations, selected colors and satisfaction with outputs were investigated on a 7-point Likert scale. And color combination characteristics of outputs were compared. It was found that the material design color palette made it easy to select colors by systematizing the regular coloring stages of fixed colors automatically, but there were differences in color compositions and color scopes of dominant color, assort color and accent colors, which are three-color combinations of mobile web application and accent color selection function was required for each design, since only primary colors and secondary colors could be selected. Moreover, chromatic colors were used a lot in the material system because of the fixed color scopes and color combination scopes and images of color combination outcomes varied depending on the color combination scopes, even when tones with a big contrast or complementary colors were selected. The role of color composition was important according to the color combination scopes.

Recently, sudden interests of mobile cloud computing as well as conventional internet environment are rapidly increased as cloud computing spread out in our web society. Mobile devices including smart phone are rapidly changing in a wholesale way that covers hardwares, applications, and services. However, the Internet access using mobile device is not quite smooth in this local mobile internet environment which suffers from lack of understanding and observance of Web Standards. Although most of domestic web sites are developed focusing on various functions and eye-catching designs, this should became one of the main factors that make the usability and accessability decrease when accessing web with smart phones or table PCs. Therefore, this paper suggested a web interface that considered usability and accessability under mobile cloud environment and we tried to prove it via usability test. It could be found that there was an improvement of usability of interface of the main page that has been optimized to the mobile device environment suggested from the previous research we present, but this paper aimed to prove a usability improvement of total website as a whole by performing the usability test on the entire website. Selecting a special website optimized for mobile cloud computing, we prove an improvement of usability and accessibility. Therefore, we offer a guideline about user interface design applications to developers or companies who want to construct mobile website.

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.

In this paper, we evaluate the feasibility of a motion-based interaction for image browsing in the mobile device. We present the design of a motion-based interface and a navigation scheme. A designed interaction scheme was evaluated in a usability experiment alongside the conventional button-based interaction for image browsing. After enough training of user, the usability and the user task performance of the motion based interaction were significantly increased, approaching those of the button based interaction.

As the market of music download stores moved into the mobile epoch the market was growing explosively. Recently, the digital music market tends to move from the mp3 download market to streaming service and the users can use the service on their mobile devices without reference to any inconvenient download and limited storage capacity. It was found that they mainly use the recommendation music playlist, instant player, main player and sharing of the functions of the streaming service from the user behavior research. This is noticeable features that set apart from the mp3 download service. However, the interface design of the streaming app followed the previous service and it needs the optimization of its UI design. In this study, the usability of high ranked three mobile streaming apps was evaluated. The result of the test was that Naver music and Bugs had high scores overall in four sections of the streaming service features. On the other hand, the Melon had primarily high score in color application on the service. The aim of this study is to suggest the direction of the UI design of music streaming service through the understanding of essence of streaming service and evaluation the usability test.

With the growth of the global sharing economy market, various sharing services have recently appeared in South Korea. Seoul city unmanned public bicycle rental service, "Ttareuni" is one of the services representing the shared mobility industry in South Korea. Although many users use this service, the usability of the mobile application, which is the essential medium of utilizing the service, is not improving. In this regard, this study conducted usability testing and in-depth interviews for Ttareungi's main users in their 20s and 30s to improve the user experience of the mobile application of Ttareungi. As a result, the problems of Ttareungi mobile application were identified, and based on this, design considerations for shared mobility services having publicity like Ttareungi were proposed. This is expected to contribute to improving the user experience of shared mobility services.
