Recently, an introduction of the cloud computing causes rapid changes in every aspect of the internet environments including hardware, operating systems, applications, and their services. As the cloud computing environment based on SaaS are being developed to a form in which web platform technology and web cloud services are converged. The digital library system also has been being developed to a service model optimized to SaaS based cloud computing environment, which are different from ASP technology. From the web interface point of view, user customization of the SaaS based cloud computing environment is the most important fact. Therefore, this research work suggests a customized web interface considering usability and accessibility so that enterprises and individual users can be able to do an effortless internet browsing under the cloud computing environment. For this purpose, usability tests were carried out as the user customized web interface design were developed and applied to the LinkSaaS website. This paper work lastly presents an UI environment on which customized interface design for individual users can be formulated.

스마트웨어가 사용자 중심으로 다변화 되어가는 유비쿼터스 환경속에서 상황정보를 제공하는 것은 서비스 전략의 중요한 성공요소가 되고 있다. 상황인식은 현실의 상황을 정보화하고 이를 활용하여 지능화된 개인화 서비스를 제공하는 기술이다. 본 논문에서는 상황인식을 이용한 맞춤형 패션 디자인 스타일 추천을 제안하였다. 제안된 방법은 사용자에게 자신의 선호도에 부합하는 패션 디자인 스타일을 제공함으로써 이를 얻기 위한 시간과 비용을 줄여주고, 손쉽게 원하는 스타일에 접근하도록 한다. 상황인식은 개인화 서비스에 필요한 상황정보를 추출하고 분류한다. 그리고 상황인식 기반의 필터링으로 패션 디자인 스타일 추천을 함으로 사용자에게 보다 다양한 서비스를 제공할 수 있다. 이를 사용자 인터페이스로 구축하여 논리적 타당성과 유효성을 검증하기 위해 실험적인 적용을 시도하고자 한다.

Since the emergence of the smartphone and tablet PC whose wireless internet accessibility has improved, personal computing environment has shifted from PCs to mobile web based mobile devices, and therefore the use of information and the communication method have been changing rapidly. Under the circumstance, domestic universities have actively been establishing mobile websites for smartphone users. Such mobile websites, however, focused on diverse functions and a showy design rather than on usability or accessibility, and were developed simply for the purpose of public relations. For this reason, students are now faced with difficulties in using the websites. Therefore, this paper proposes a novel web interface with the consideration of usability and accessibility in order for users to easily use and assess proper information. The matters to be taken into account in developing a mobile website are an intuitive interface design, user experiences, a user customized interface and compliance with web standards.

Recently, the number of People who want to study by online has been gradually increased. In addition, people's desire is increasing that represents their special knowledge and personality with new paradigm of UCC(User Created Contents). Most of the educational web-sites offer currently boring and unified educational contents without interesting objects. Therefore I want to solve these problems of existing online educational web-sites and I strongly propose the method of design to make the place educational and useful that everyone can enjoy and manifest the user's dispositions. On this study, it's possible to make pleasant environment and improve educational effects on cyber space by designing it in accordance with the individual tastes which have various design elements, beauties and facilities by the customized design method. As a result, this study proposes the model of online educational web-site having various interfaces and focusing on the customized design.

This study uses the bidet 4D double diamond design process model to propose an improvement for "senior-oriented bidet product service design" that reflects the characteristics and needs of seniors. This study was based on the product service system concept. To this end, qualitative research on seniors was conducted to derive user value factors, and, based on this, product service ideas were discovered, and a prototype reflecting the usefulness review of a working-level expert group was proposed. First, a "smart application service for user-customized function setting guide" was proposed. A bidet incorporating Internet of Things technology and a smart phone are linked to provide an app service that automatically interprets user characteristic information and information on bidet products to guide customized functions. Second, a control panel and remote control user interface to "user-oriented product service interface" was proposed. In consideration of the usability and cognitive ability of seniors, a simple and intuitive physical user interface such as a configuration centered on main functions, button arrangement according to task sequence, and a touch screen remote control was presented. Third, we proposed a "bidet care service linked with products and health/hygiene care" that provides a wide range of services such as user health and hygiene, cleanliness, entertainment, etc., in addition to regular bidet product service. This study proposed a product-based service design methodology that can improve user experience and relationship quality by discovering and improving the pain points and needs of users (seniors) in the process of using bidet products (before, during, and after use).

With technological development of product designs, products of various concepts have been developed and products by customized design concepts have been actively launched. For successful development, it is necessary to convey the target concept to the product development process exactly in order to create the targeting design. The study found the design concept of mobile phones with a boom box through emotional verbal expression, and defined the concept target by using visual images in accordance with the relative target with a view to looking for the design concept suitable to product development target. Regarding the visual image, the test for coordination among participants was conducted to select the image on which the interest groups participating in the development reach an agreement. As a result of the test, it aimed to propose the method to select concepts and images for rational choice by means of clustering algorithms. This method is considered to contribute to building the design concept and actualizing GUI design.

Recently, among smart phone functions, cameras are one of the most popular functions and have become one of the most influential functions for purchasing smartphones. However, the basic camera application of the smart phone has a complicated user environment, which is causing many difficulties for the first time user. In this study, Galaxy S7, which is the newest Galaxy S series among the most used Galaxy S series in Korea, was selected and the usability test of the camera application was limited to shooting and editing sharing functions. As a result, first, improvement of icon graphic and label of text form should be provided at the same time to increase the recognition rate and attention of the icon. Second, it is necessary to simplify the structure and provide an intuitive interface in order to facilitate access to various modes and functions. Third, it is necessary to simplify the provision of personalized customized menus or functions in the development of the camera application because it causes a high failure rate and inconvenience in the special functions which are not widely used.

Mirror is a physical reflective surface, typically of glass coated with a metal amalgam, and it is to reflect an image clearly. They are available everywhere anytime and become an essential tool for us to observe our faces and appearances. With the advent of modern software technology, we are motivated to enhance the reflection capability of mirrors with the convenience and intelligence of realtime processing, microservices, and machine learning. In this paper, we present a development of Digital Mirror System that provides the realtime reflection functionality as mirror while providing additional convenience and intelligence including personal information retrieval, public information retrieval, appearance age detection, and emotion detection. Moreover, it provides a multi-model user interface of touch-based, voice-based, and gesture-based. We present our design and discuss how it can be implemented with current technology to deliver the realtime mirror reflection while providing useful information and machine learning intelligence.
