The domestic game market is still on a trend of growth. Particularly, as the demand for mobile games is increased, the mobile version is developed in a growing number of cases even after the launch of the games for PCS. In a bid to search for the effective method of UI design depending on the differences between the platforms, this study analyzed the types of different media in the first place and as the approaches to the UI design based on the affordance concept, implemented on the platform of PCS and implemented on the platform of mobile devices were analyzed as the cases which are the same MMORPG games. Since the differences between the game platforms can cause the variations in the physical size of the screens depending on the environment in which the user interface (UI) is rendered and may often involve the controls implemented by the touch of screens rather than the manipulation based on the keyboard and mouse, they usually give the influences on the direction of UI designs. By analyzing these UI elements based on the affordance concept, it may be possible to find the effective method of UI design in the future.

UX (User Experience) Design was an interdisciplinary approach in humanities, engineering, science and design. We classified the roles of user experience; requirement analysis which are user research, constraints analysis and direction analysis, concept design, information architecture, physical UI, graphical UI, sound UI, Olfactory UI, prototype, evaluation, launch, localization, and knowledge management/UI DB. User research methods were classified by the relation of designer, user, and product/service. We reviewed three issues of UX design; complexity management, efficiency management, and mapping management.

In this paper, we propose an implementation of user interaction effect of web application using jQuery. jQuery is a very popular and extensible JavaScript library. It is strong in controlling DOM(Document Object Model), events and Ajax. But, it is poor at advanced effect of web user UI(User Interface). Implementing advanced effects need to extend jQuery or some skills. So, our proposal is a good way to implement UI effects.

The purpose of this study was to find the effective way of composition in terms of UX(user experience) when configuring UI(user interface) of educational game by utilizing ET(eye-tracking). Experimental material was a game related to the middle school 'force and motion'. SMI (SensoMotoric Instruments)' iView X TM RED was used in order to collect eye movement data. The results of this study was as follows. First, the lead element for fast visual attention should be placed in the center when the educational game UI is configured. Second, burton that changes character's features and the information about them should be placed close to each other. Third, learning quiz caught visual attention faster when it was placed on the left side of UI. Fourth, when one UI was overlapped by another, parts that were not overlapped was fixated, too.

Generally, operators suffer much difficulty in manipulating micro-nano-sized objects without assisting of human interface, due to the scaling effects in micro/nano world. Thus, the micromanipulation system based on the teleoperation techniques enables operators to manipulate the micro objects easily by transferring both human motion and manipulation skills to the micromanipulator. In teleoperated microassembly, it is necessary to provide a useful user interface for facilitating micro assembly task executed by human operators. In this paper, Intelligent User Interface (UI) for teleoperated microassembly is proposed. The proposed intelligent UI improves task performance by teleoperated micromanipulation as well as guides operators to succeed in desirable ...

In the process of development the e-learning course at Cyber University, one important factor to be considered for the effective e-learning contents is the User Interface(UI) of the e-Learning content platform. The User Interface is important because the well-designed UI can help students to perform effectively and easily learning activities. Despite the importance of the usability, few attempts have been carried out to design the e-learning contents UI from the usability perspectives. Thus, the purpose of this study is to explore the usability design elements for the e-learning contents UI. For this purpose, a usability evaluation study on the e-learning contents UI of a cyber university at Seoul was conducted. Implications for the improvement of the current e-Learning contents UI was presented.

Smart-phone Applications are consists of UI(User Interface). During using applications, UI events such as button click and scroll down are transmitted to Smart-phone system with many changes of UI. In these UI events, various information including user-input data are also involved. While Keylogging, which is a well-known user-input data acquisition technique, is needed a restrictive condition like rooting to obtain the user-input data in android environment, UI events have advantage which can be easily accessible to user-input data on user privileges. Although security solutions based keypad in several applications are applied, we demonstrate that these were exposed to vulnerability of application security and could be obtained user-input data using UI events regardless of presence of any security system. In this paper, we show the security threats related information disclosure using UI events and suggest the alternative countermeasures by showing the replay-attack example based scenarios.

Recently, we should control various devices such as TV, audio, DVD player, video player, and set-top box simultaneously to manipulate home theater system. To execute the function the user want in this situation, user should know functions and positions of the buttons in several remote controllers. Normally, people feel difficult due to these realistic problems. Besides, the number of the devices that we can control shall increase, and people will confuse more if the ubiquitous home environment is realized. Therefore, user adaptive interface that provides the summarized functions is required. Moreover there can be a lot of mobile and stationary controller devices in ubiquitous computing environment, so user interface should be adaptive in selecting the functions that user wants and in adjusting the features of UI to fit in specific controller. To implement the user and controller adaptive interface, we modeled the ubiquitous home environment and used modeled context and device information. We have used Bayesian network to get the degree of necessity in each situation. Behavior selection network uses predicted user situation and the degree of necessity, and it selects necessary functions in current situation. Selected functions are used to construct adaptive interface for each controller using presentation template. For experiments, we have implemented ubiquitous home environment and generated controller usage log in this environment. We have confirmed the BN predicted user requirements effectively as evaluating the inferred results of controller necessity based on generated scenario. Finally, comparing the adaptive home UI with the fixed one to 14 subjects, we confirmed that the generated adaptive UI was more useful for general tasks than fixed UI.

The purpose of this research is to analyze priority of the elderly user interface (UI) evaluation criteria based on user's lifestyle. Since the elderly population will occupy over 20% of the all Korean population in the near future, we need to know older users' needs and information because elderly users will be main customers in the super-aged society. This paper investigated the definition of elderly users and characteristics demographically, socio-economically, and physically/cognitively. A total of 238 questionnaires from older users were analyzed based on a segmentation table for the elderly developed by the previous study. According to factor analysis and cluster analysis, 6 types of lifestyle and 4 groups of the elderly users were classified, respectively. The priority of UI evaluation criteria for large electronic home appliances and mobile products was analyzed by analyses of variance (ANOVAs). The results indicated that the priority of (physical, emotional, and cognitive) UI criteria was significantly different among elderly users' lifestyles for both home appliances and mobile products. Consequently, the results of this study may help the company develop some competitive silver products and give higher satisfaction to the elderly users by suggesting different priority of UI evaluation criteria according to the target elderly group. The results may also contribute to revitalize national economy by significantly increasing senior market shares.
