The technology convergence of television, communication, and computing devices enables the rich social and entertaining experience through Smart TV in personal living space. The powerful smart TV computing platform allows to provide various user interaction interfaces like IR remote control, web based control, body gesture based control, etc. The presently used smart TV interaction user control methods are not efficient and user-friendly to access different type of media content and services and strongly required advanced way to control and access to the smart TV with easy user interface. This paper propose the optical wireless communication (OWC) based remote controller design for Smart TV using smart device Flashlights. In this approach, the user smart device act as a remote controller with touch based interactive smart device application and transfer the user control interface data to smart TV trough Flashlight using visible light communication method. The smart TV built-in camera follows the optical camera communication (OCC) principle to decode data and control smart TV user access functions according. This proposed method is not harmful as radio frequency (RF) radiation does it on human health and very simple to use as well user does need to any gesture moves to control the smart TV.

Upcycling is a sustainable way to recycle waste resources and solve the global problem of environmental pollution. Upcycling is now attracting attention as fiberization and the disposal of waste clothing have become a serious issue. However, the customer's willingness to purchase upcycled products should be increased by propagating that the product value of a reborn commodity is of high value; these products are meant for new purposes and prepared with recycled materials. In this study, we created 11 designer items by applying an eco-friendly concept in the design process of upcycled textiles and products. From 2020 to 2021, a PBL(Problem Based Learning) curriculum was taught in design planning classes. The final 11 design items were derived after developing an eco-friendly product design for upcycled textiles. These final items were as follows: 5 fashion bags, 3 dog products, 1 clothing, 1 fashion accessory, and 1 sanitary mask design. In order to develop only one aesthetic design idea for upcycling, we considered the following features: user-centered convenience, functionality, and practicality. Then, tie-dye, drawing, patchwork, and embroidery were used to create innovative design items. The product design of recycled materials is based on high functionality, waterproofing, and the use of organic natural materials. The results of this study indicate that the creative product design of upcycling has contributed to a sustainable and eco-friendly environment. Related research studies must be conducted for innovating the continuous design process of the future.

This paper deals with interface design of a university webzines that to search through an internet portal site Naver. It was obtained the following conclusions. First, university webzines are using a hypertext link to such images, text, movie. Second, it could be seen that mainly been using block grid, the module grid, and a transformed layout of 2 tier grid. Third, Seoul woman's University, Kyungpook National University, and Korea Maritime University's webzines found that layout, color, user-friendly access the structure. Fourth, webzine was used the text or image a link, search function, site map, icon, favorites, quick menus, navigation bars, and rollover menu. Last, university webzines were shown to contribute mere to the enhancement of its value as a promotional medium.

In this study, a user oriented CFD program for optimum design of a regenerative combustion furnace, REBURN was developed. For user's convenience, user friendly Graphic User Interface was made and the renumbering interface program was developed in order to directly input any generated mesh system from ICEM CFD/FEA. Also an automatic processing system for switching mode was developed. The program was verified through compahng with commercial CFD code about regenerative combustion furnace. Then, numerical simulation of real walking beam furnace used in real industry was performed and the parametric analysis was studied about the arrangement mode. As a results, the uniform temperature was appeared in the cross mode.

In smart era, concept of User experience has been an important issue both in academic and practical areas in recent years. Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user?centered design methodology which uses the influential factors on the interactivity. As, well developed information technology made a lot of changes to various fields of our society, interactive space with the concept of HCI became a big issue in environmental design field. In this interactive space, various types of informative factors of the given space are sent using sensor and computer networking technology to the main system. So, a user's movement in the space in more than just a movement itself-user's movement now forms a important spatial structure that leads the narrative of the space. in this research, I will come up with the problems that the interactive space has right now, and analyze what the public space must have, and combine them with interactive space by HCI theory. architecture space is not the old space adapting digital technology. In order to take the role as new space paradigm. environment and technology, it has to develop technology continuously and experimental space at the same time. It must have co-evolution of architecture space field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion and user centric human friendly.

Smart City is a future-oriented city that provides users with desired services through various devices anytime and anywhere using Information and Communication Technologies (ICTs). In order to provide the smart city service desired by the user, the user-oriented design concept should be based on above all. The design and development process must be based on the opinions and needs of everyone involved and needs to ideally reflect all user information and feedback, including users, designers and stakeholders at all levels. Participatory design approaches can be seen as an attempt to better understand and engage real users, and they are essential and important to create more appropriate and user-friendly smart-city services. This study has recognized the importance of developing a smart city service from the viewpoint of user - centered design and examined the methodology of design thinking and service design process for smart city service development. User - centered design concept model for smart city service design was designed, and serviceability case developed based on concept model was verified.

research on user-friendly experience design is crucial to reduce resistance and enhance acceptance of robotaxis. This study analyzes the prioritization of design factors in robotaxi systems and provides design guidelines based on user experience. Using the AHP(Analytic Hierarchy Process) technique, users' perceived importance of four primary design factors and sixteen 16 sub-design elements were assessed, and comfort and safety were top priorities. The results showed that the artificial intelligence agent was the most critical design factor, followed by driving guidance information, interior design, and exterior design. These findings offer valuable insights for robotaxi professionals, and could assist in informed decision-making and creating user-centered design guidelines.
