The worldwide population is aging rapidly. In this circumstance, Korean society is in need of the urgent comprehensive countermeasures that will help the elderly with their health problems and infection control in their daily life. Universal design has supportive, adaptable, accessible and safety-oriental design standards for the elderly. Is this study, we propose the guidelines of the mobile application development based on the application of the universal design for infection control in the elderly. From the perspective of the universal design, there are several important guidelines including 'generalized access', 'simple and intuitive usage', 'low physical effort', and 'visualized language' based on the KCDC(Korea centers for disease control and prevention) principles for the elderly. These findings show that the guidelines for improving the health literacy of the mobile application via universal design are necessary to enhance the health behavior of infection control for the elderly.

The design functionality put forward by mapping the interactiveness of information. The presentation of such information with the user interface model indicates that the guidelines, concepts, and workflows form the deliverables and milestones for achieving a visualized design, therefore forming the right trend is significant to ensure compliance in terms of changing consideration and applying evaluation in the early stages. It is evidenced that prototype design is guided by improvement specifications, includes modes, and variables that increase improvements. The study presents five user interface testing methods. The testing methods are heuristic evaluation, perspective-based user interface testing, cognitive walkthrough, pluralistic walkthrough, and formal usability inspection. It appears that the five testing methods can be combined and matched to produce reasonable results.

The current study examines principles to develop universal design guidelines for manufacturing information and communication devices. The study surveyed inconveniences disabled people experience in the information and communication environment with current technology and design, and suggested abbreviated universal design guidelines. Design guidelines should reduce those inconveniences detected through the task analysis and GOMS modelling of the usage by disabled people. Design and functional features of mobile phones were examined since they quickly became essential communication tools for both disabled and non-disabled people alike. Design issues were examined in controls, input methods, and output methods in terms of human factors and ergonomics. It is expected that both governments and manufacturers can save costs to produce and manufacture special assistive devices for disabled people by implementing universal design in their communication products. Since it is becoming the international trend, application of the universal design should be enforced to all communication and information devices by government for the higher quality of life for all groups of user.

With the rapid growth of the mobile application market, mobile donation applications have emerged as a new type of application that enables users to donate without actual payments. To date, limited research has been conducted to provide guidelines on how to design new types of mobile donation applications. Using cause-related marketing theory as theoretical framework, this study aims to identify the features of mobile donation applications that increase the intention of users to use such applications. To achieve this goal, we conducted two experiments. The results of an ANOVA test in the first experiment showed that indirect mobile donation applications (i.e., applications without actual payment) have a stronger positive effect on perceived effectiveness and cause involvement than direct mobile donation applications (i.e., applications with actual payment). In addition, perceived effectiveness and cause involvement yield positive effects on the intention to use mobile donation applications. The results of the second experiment showed that indirect mobile donation applications with utilitarian functions have a greater positive effect on perceived effectiveness and cause involvement than mobile donation applications with hedonic functions. These results contribute to mobile application and donation research as well as provide guidelines for practitioners on the design of mobile donation applications.

The importance of User Interface (UI) in mobile phone has increased as the complexity of use increases due to the new technology adoption. The complexity and load for user interface development has increased accordingly. This paper discusses how to make a structured UI development process based on the mobile phone UI development case. After the review of UI development process and issues arising during the development, four levels of user interface guidelines are proposed such as macro rules, action templates, application rules and interaction cases. The importance of dealing various interaction case is emphasized which is not referred in the present industry UI guidelines. Most of research related to UI development focus on the target product rather than how to make good UI process. Based on the good UI process, good UI of the product can be realized. This proposed process based on UI guidelines will help to step up the UI development of mobile phone industry. Also, this process can be applied to different products or services.

After the spread of COVID-19, the OTT market has grown rapidly. Accordingly, competition of OTT platforms has intensified. Among them, TVing provides users distinct characteristics of service, such as media and commerce, to differentiate it from other platforms. It is important to offer appropriate usability when proving combined service in one mobile application. Otherwise, it can adversely affect the user experience. In this regard, this research conducted usability testing of TVing and found out what user experience should be considered when integrating different characteristics of service in one mobile application. Through the usability testing, we measured and analyzed effectiveness, efficiency, and satisfaction based on the ISO usability testing guidelines. As a result, three important considerations of UX design for mobile application of combined services were found; 1) connectivity between services, 2) easy navigation, 3) consistent UI design, and 4) relations between subjects and provided information. This design consideration is expected to be applicable not only to TVing mobile application, but also to the situation where composed services are provided in one application.

Objective: The aim of this study is to investigate the attributing factors influencing usability of the mobile phones specifically designed for the elderly users. Efforts to identify factors that cause usability problems for the elderly users in using mobile phones can provide the groundwork for changes aimed at usability enhancement and design of interfaces of mobile phones. Background: It became important to understand the behaviors and tendencies of the elderly in communication as the society became older. The problems in digital divide is contributed to mainly lack of understanding in terms of the use pattern of the elderly and lack of consideration of their characteristics in designing user interfaces of most ICT devices. Method: A total of 30 elderly users who were over 65 years in age participated in usability evaluation test experiment and performed seven different tasks using a widely accepted model of universally designed mobile phone. Their performance was compared with that of contrast group that consisted of 10 younger participants who were on their 20s. Results: It was found that the elderly users had hard times in using mobile phones, especially in keypad manipulation among search, understanding, and manipulation subtasks. Conclusion: Older users seemed to have difficulty in all the subtasks of search, recognition, and manipulation. It was suggested that designers of mobile phones need to give careful consideration into designing visual interfaces for search tasks and keypads for easier control and input for the elderly users. Application: The study is expected to provide guidelines for the universal design of mobile phones and their interfaces for enhancing usability of the mobile phone for elderly users.
