The post-corona era is having a major impact on university campus life, and campus cultural life has undergone drastic changes. In the process of adapting to this change. The existing face-to-face learning method is converted to non-face-to-face learning, and kiosks representing campus self-service are increasingly used. Subsequently, in order to match the characteristics of public places such as university campuses and provide better self-service, there are no related studies considering UI design elements of kiosks and characteristics of kiosks. This study conducted a survey on Chinese university students considering the characteristics and usability of university campus kiosks through user interface design elements in terms of design by considering previous studies. The purpose of this study is to examine the relationship between color, icon, typography, which are elements of kiosk interface design, and convenience, reliability, and usability, which are characteristics of a kiosk. In this study, the design elements and characteristics of the unmanned self-service system kiosk UI used by students at four universities in Korea and China were set as the scope of the study, and related documents were organized and surveyed in Korea and China.

In recent years, a platform providing a Visual Programming development environment capable of 3D editing and interaction editing in an In-VR environment to quickly prototype VR/AR contents for education of VR and AR for general users and children. In the past, VR contents were mostly viewed by users. However, thanks to the rapid development of recent computing technologies, VR contents interacting with users have emerged as a device capable of tracking user behavior in a small size It was able to appear. In addition, because VR is extended to AR and MR, it can be used in all three virtual environments and requires efficient user interface(UI). In this paper, we propose UI based on eye tracking. Eye-tracking-based UI not only reduces the amount of time the user directly manipulates the controller, but also dramatically lowers the time spent on simple operations, while reducing the need for a dedicated controller by allowing multiple types of controllers to be used in combination. The proposed platform can easily create a prototype of their intended VR/AR App(or content) even for users(beginners) who do not have a certain level of knowledge and experience in 3D graphics and software coding, and share it with others. Therefore, this paper proposes a method to use VAL more effectively in a 5G environment.

Due to the development of communication technology and expansion of Intelligent Transport System (ITS), the car is changing from a simple mechanical device to second living space which has comprehensive convenience function and is evolved into the platform which is playing as an interface for this role. As the interface area to provide various information to the passenger is being expanded, the research importance about smart car based user experience is rising. This study has a research objective to propose the guidelines regarding the smart car user experience elements. In order to conduct this study, smart car user experience elements were defined as function, interaction, and surface and through the discussions of UX/UI experts, 8 representative techniques, 14 representative techniques, and 8 locations of the glass windows were specified for each element. Following, the smart car users' priorities of the experience elements, which were defined through targeting 100 drivers, were analyzed in the form of questionnaire survey. The analysis showed that the users' priorities in applying the main techniques were in the order of safety, distance, and sensibility. The priorities of the production method were in the order of voice recognition, touch, gesture, physical button, and eye tracking. Furthermore, regarding the glass window locations, users prioritized the front of the driver's seat to the back. According to the demographic analysis on gender, there were no significant differences except for two functions. Therefore this showed that the guidelines of male and female can be commonly applied. Through user requirement analysis about individual elements, this study provides the guides about the requirement in each element to be applied to commercialized product with priority.

Smartphones have been widely used for various purposes and stay connected with people at all times. However, the use of such touchscreen devices can be physically restricted depending on users' context where only one hand is available to interact with the device. Even major smartphone manufacturers (e.g., Apple, Samsung) offer one handed mode, they still lack functions in the third-party applications, and the process is also complicated. We propose OverIT, a system that enables users to customize interfaces by adding new buttons on an interactive overlay which can be positioned anywhere on the touchscreen where each button serves the same functionality as an existing one. It is designed to support users to map a certain button event freely and easily to a newly created button by performing a demonstration of a button tap. We expect our system to improve the overall user experience of one-handed interaction with touchscreen devices.

In the IT industry, processing units of IT applications are getting smaller and high efficient. Furthermore, the realization of various smart functions is highly feasible now due to advances in sensing technology. The service infrastructures on high efficient and compact mobile devices are applied to various areas. These also could be possessed by users and is built into the devices. Currently, studies on the UX(User Experience) field to attempt an analysis and prediction of user's information are continuing with reference to the UI(User Interface). However, research on the common framework of classification and storing the user-information, and standardization of form has not been attempted yet. In this study, we proposed the AUX(Associative user Experience) model and process structure to store various empirical data by users. The AUX model expressed a diversity of user's empirical data using extended E-TCPN model. And also, we expressed the data structure using XML with reference to the application of AUX model. This expressed model and separation of process structure guarantee its specialty, productivity and flexibility through the humanistic characteristics of users and the independence of technical process structure. The AUX model maps out the AUX information process architecture and expressed the process with the improved MPP algorithm, to analyze of its performance. The simulation of movements applying to MPP traffic allocation of VOD is used to analyze of its performance. The playback deviation of MPP Graphic Allocation Algorism where the AUX model was applied was improved by 10.41% more than the one where it was not applied. As a result of that, playback performance has improved due to the conversion of AUX with accessing media, content of users and dynamic traffic allocation such as MPI and CPI.

Purpose: The purpose of this study is to identify the real condition of urinary incontinence(UI), interstitial cystitis(IC), atrophic viginitis(AV) for elderly women and analyze the cognition of traditional korean medicine(TKM) for them. Methods: We utilized questionnaire from May to June, 2010. Questionnaires were taken from 125 women using senior welfare center and nursing home, aged over 65 up to 92. The data were analyzed by $X^2$-test using SPSS/PC ver 18.0 program. Results: The prevalences of UI, IC and AV symptoms were 50.4%, 40.8%, 56%, respectively. The average I-QoL score for UI was $82.62{\pm}21.16$, and the average ICSI score for IC was $8.16{\pm}2.50$. After adjustment for each of the variables considered in this study, alcohol was associated with UI and age, BMI(body mass index) were associated with IC. Most of respondents have no experience(94.4%) or don't know (79.2%) about TKM for UI, IC and AV. 44 women(37.3%) indicated that they weren't willing to use TKM for UI, IC and AV. Reasons for not taking TKM were because of 'no knowledge of TKM(34.1%)' and 'more accustomed to western treatment(34.1%)'. Conclusion: Although the prevalence of UI, IC, AV for elderly women was high, the actual percentage of treatment for these diseases was low, furthermore, patients were not aware of TKM and had very few experiences of TKM for these diseases. The development and increased promotion about TKM program for elderly women's urogenital diseases is needed.
