People established a network much more using smart equipments by means of the development of the mobile industry. They can get useful information easily, make new personal connections and communities, and form various personal connections using the communities. The importance of contact, timing, and utility of time plays an important role in human relations. Many programs related to personal relations are already saturated. In other words, they are very significant and difficult to use. Many programs that didn't be concerned ahead of time about how to deal with a lot of the amount of information effectively and take it out in order to use it could bring about negative results. Human being already makes use of physical-empirical language in all of the conscious and unconscious areas. This study begins at the supposition that how to make it easy to apply humane gestures and languages to applications with portable equipment close to human beings.

Stock information applications allow users to look up and find current stock information whenever and wherever. This study researched what kind of user experience the finance experts get when using these applications and what they suggest. The research was conducted through an in-depth interview of 8 finance experts, who worked minimum of three years, and used both Kakao Stock and JeungGwon Tong, the most used stock information applications, for a minimum duration of six months. The results show the user experience of Kakao Stock rated a bit higher than JeungGwon Tong. Since the objective of such applications are to show stock informations, the experts all rated the pleasurable and meaningful aspects rather low. They suggested, the developers should provide a more advanced and accurate information. They also suggested user interest recognized content be presented along with more convenient user interface to elevate usability. Hopefully, this study becomes a base to further study of user experience of various on and offline stock information services and they become a reference to develop a service with great user experience.

Displays, playing an essential role in HCI, have been developed to deliver more vivid and live pictures. LCD and PDP have the most common usage among various displays to present the dynamic textual information in restricted and open places. Important and unsolicited information is being provided by hundreds of displays while we don't even perceive the information. Watching context, effective color combinations of the text and background, speeds of presentation, contexts, and types of display for leading method, moving words cross the display from right to left, were investigated with readability, comprehensibility, and overall satisfaction were compared. LCD peformed better than PDP on all comparisons u4th typical text (black, white) and background (white, black) color better than other color combinations. Normal and fast text presentation was believed more preferred when only textual information was given while slower presentation was evaluated more efficient if multimedia contents were presented with textual information.

This paper proposes an integrated management system for products of game software development. Those products generated over software life-cycle are generally huge in numbers, various in kinds and interconnected in relationships among them. Especially they are highly complex and tightly coupled each other because they are used to build another world which is composed of multi-modal data such as graphics, sound, logics and so on. Therefore it is critical to manage development products in an integrated manner to guarantee the quality of software. The proposed system is designed to provide project/requirement/configuration/traceability management capabilities and interfacing to CASE standards. To achieve the objective, it is based on data warehouse technologies which provide central repositories of heterogeneous data, multi-aspect reporting&analysis capabilities, traceability, verification, etc.

In this paper, we design and implement watermarking system which create, insert and detect watermark comprised of number or logo to protect copyright and to prevent illegal plagiarism through inserting copyrighting information of owner into the original image. In the proposed system, the number or logo as watermark is selectively inserted according to characteristics of the original contents or requirement of copyrighter. The system also has convenient user interface which general administrator who hasn't expert knowledge for the protection of copyright uses easily. Ownership and copyright protection using digital watermarking technology intensifies creating volition of clients who want to create contents such as cultural contents, Thus, we can expect increasing requests for creating contents such as cultural contents.

This study is a study that analyzes the user experience of a virtual makeup application in the beauty industry where color or formulation testing is important. Recently, cases of beauty smart stores and beauty applications using AR and AI are increasing. However, since virtual makeup is different from testing a real product, it is necessary to derive needs through research from the user's side. In order to compare user preferences by using AR and AI cases, six factors based on the emotional interface model were analyzed through a questionnaire to identify items with statistically significant figures. As a result, the user felt comfortable with the virtual makeup function, but showed that it needs to be supplemented in terms of reliability. Since this study focused on the customer experience as a real user and identified the main experience factors and needs of virtual makeup through two types of comparison, it is hoped that this study will be useful as a prior study.

Domestic credit card companies and wireless operators want to deliver promotional information as well as the information for users on the site. A careful UX design is needed because promotional information can degrade the satisfaction of the users. In addition, too extensive information is provided on one site and users are confused about where to look for the information they need. Based on advanced research, study was conducted of the domestic web sites of wireless operators and credit card companies and we discussed that study with 12 users. Promotional information can be efficient with understated image. Users can find information easily from the site with fewer hierarchy of steps. The numbers of the menu that is presented at a time should not exceed nine.

Recently, with the advent of the 4th Industrial Revolution, the diversified industrial base and stable employment market have led to increased concern on the metropolis centered manufacturing. However, To enhance the added value and competitiveness of the manufacturing industry in Seoul, it is necessary to develop specialized smart-based technology and production, and to establish a collaborative system among various businesses in the areas of planning, production, and logistics. Accordingly, I planned a service that is necessary for activation of the urban manufacturing industry in Dongdaemun area of Seoul to enable designers to construct an infrastructure for direct production. The proposed content is a hands-on application that provides information to producers who want to make their own unique products with which they can buy materials from Dongdaemun, Cheonggyecheon, and Uljiro areas.

We introduce a new framework for making spatial augmented reality contents fast and with low cost. The framework allows us to make projection-based augmented reality using off-the-shelf webcams and projectors. Contents producers can make a projection-based augmented reality contents easy and fast by setting a webcam and a projector and then controlling user interfaces of our framework. Since most of previous solutions are expensive and it is too difficult that the producers apply augmented reality techniques themselves, the framework helps them to concentrate contents. Once we set a webcam and a projector correctly, our framework projects a virtual object contents according to the manipulation of a trackable real object. As a result we can see realistic augmented reality contents.
