비디오 월 컨트롤러의 멀티스크린에 여러 영상을 동시에 표출하고자 하는 경우, 운영자는 표출할 영상의 레이아웃을 미리 저장해두고 필요할 때 이를 불러와서 표출한다. 비디오 월 컨트롤러의 운용 중에 발생하는 상황에 따라 레이아웃이 달라지므로 모든 상황을 고려하여 레이아웃을 저장하는 것이 일반적인 운용 방식이다. 멀티스크린의 모니터 개수가 많지 않은 소규모의 시스템에서는 서너 개의 레이아웃을 저장하는 것만으로 충분하지만, 모니터의 개수가 늘어날수록 레이아웃 디자인의 경우의 수가 늘어나므로 레이아웃의 디자인과 관리에 많은 시간과 비용이 소요된다. 따라서 본 논문에서는 CGAN을 이용하여 비디오 월 컨트롤러의 레이아웃을 자동으로 생성하는 모델을 제안한다.

In this paper, we study for the design and verification of a 16 bits micro controller, which is compatible with a 8 bits micro controller, 8051, widely used in the industrial fields these days. To confirm our design, we verified our design for all instruction sets and various combinational sets of them. Also we propose a new idea for the verification of various instruction sets, We verified our design through some application programs such as IMA-ADPCM, SOLA. Finally, we verified our design for all instruction sets and application programs through an application board, used Xilinx FPGA(XCVl000-560C). After the comparison our design with a 8051 for various cases, We concluded that we could substitute our design for a 8051 and our design could be operated more powerfully than a 8051.

The Ministry of Public Safety and Security plans to expand fire safety education infrastructure to provide customized fire safety education, spread fire safety culture and develop a tailored fire safety education system as a part of the 2016 Citizens' Safety Improvement Policy. This study has also been designed to improve safety problems in the Republic of Korea. Even though safety education has been given, citizens aren't still able to experience a close-to-real situation. In addition, their understanding and satisfaction with the curriculum are very low. Therefore, this study offers VR fire-extinguishing experience education contents as an effective alternative. With a goal of having the participants experience fire extinguishing and evacuation drill in a virtual space, this program has the following advantages: i) safe fire-extinguishing experience; ii) UI to create fun ; iii) useful in fire-extinguishing education; iv) budget saving. we configure the VR fire experience system structure and hardware by applying UX design methodology. We also develop for VR-specific motion recognition plug-in and controller that can be feeling in HMD environment.

정보통신의 발달로 다양화되는 정보화 사회의 요구에 따라 디스플레이의 수요는 더욱 증가되고, 디스플레이 또한 다양해지고 있는 실정이다. 날로 소형화되고 있는 정보기기들의 디스플레이는 평판화를 통해 부피가 작고 가벼우며, 현장감과 몰입감의 증진을 위해 고감도의 그래픽을 제공하고 있다. 하지만 실험기기에 대해서는 아직 인터페이스나 디스플레이 GUI 디자인에 대한 관심이 약하고, 전체적인 제품의 외관 디자인에 관심을 보이고 있는 정도다. 이에 본 연구에서는 실험기기와 이의 주사용자인 과학자들의 특성을 고려하여 실험기기 컨트롤러 디스플레이 GUI 디자인에 대한 선호도를 분석해 보았다.

본 연구는 교육용 가상현실 게임 튜토리얼 인터페이스 구성 요소와 고려사항을 파악하여 튜토리얼 인터페이스를 디자인하는 것을 목적으로 한다. 현재 개발 중인 가상현실 교육용 게임 콘텐츠를 기반으로 튜토리얼이 제공되어야 하는 사용자 과업을 도출하였다. 그 후 상용화된 가상현실 게임을 직접 사용해 봄으로써 가상현실 게임 튜토리얼의 구성 요소를 파악하였다. 대부분의 가상현실 게임 튜토리얼은 텍스트 형태의 게임 방식과 컨트롤러 그림 기반의 인터페이스 설명으로 구성되어 있었다. 문헌조사를 통해 가상현실 게임에서 튜토리얼 인터페이스 설계 시 고려되어야 하는 디자인 요소를 분석하였고, 중앙으로부터 콘텐츠를 편안하게 볼 수 있는 범위는 좌우 약 -77도 ~ 77도에 위치되어야 함을 확인하였다. 또한, 텍스트, 버튼, 색상 요소에 관한 가상현실 인터페이스 디자인 원칙도 함께 수집하여 정리함으로써, 최종적으로 사용자 과업에 따른 가상현실 게임 튜토리얼 인터페이스를 디자인하였다. 본 연구는 추후 가상현실 게임 튜토리얼 인터페이스 제작 시 유용할 것으로 기대된다.

Due to the recent development of 3D printers, interest in 3D printing is growing. 3D printing should reflect individual needs and various requirements by designing products to suit the user's requirements. Research on how to use 3D printed products for the purpose of purchasing products according to user's demand characteristics is insufficient. Therefore, this study conducted a survey and statistical analysis to find out the factors influencing the intention of purchasing custom controller products in 3D printing environments. Research has confirmed that user innovation and convenience safety are important factors for the satisfaction and purchase intent of personal-tailored controller products. Considering user innovation, convenience, and safety when producing controller products using 3D printing, it is expected that value of custom controller manufacturing can be increased. Research is needed on the personalized product development framework that successfully introduces and systematically supports the production methods of personalized products in the early stages.

This study focused on developing MP3 smart clothing products and usability evaluation. MP3 smart clothing which was developed in this study contains e-textile keypad and a kit. The kit consists of MP3 Player, remote controller module and ear phone, and are easy to assemble and dismantle. And usability evaluation about MP3 smart Clothing which was developed in this study contains e-textile keypad and a kit. For making the MP3 Smart clothing, e-textile signal line and keypad was developed and a metal connection ring also was manufactured to adhere closely e-textile signal line to keypad. The last products are two kinds of MP3 smart clothing, jacket style of MP3-YSJ(Yonsei Smart Jacket) and safari style of MP3-YSS(Yonsei Smart Safari). Then usability evaluation conducted two times about MP3 smart clothing developed. Usability evaluation is classified by a module evaluation and an item evaluation. The module evaluation measured external appearance, material, a music controller, an ear phone(or a mini speaker) and connector. The item evaluation measured social acceptance, feeling of wearing, utility, easiness of maintenance and safety. The module evaluation described totally positive results in the first usability evaluation about MP3-YSJ 1.0 and MP3-YSS 1.0. The item evaluation shows a lower score in the social acceptance, especially the easiness of connector maintenance and the social acceptance of music-controller in MP3-YSJ 1.0 and MP3-YSS 1.0. The second usability evaluation conducted with improved products by the first usability test results. Results from second item evaluation indicated needs to improve the easiness of connector & music-controller maintenance and the social acceptance of music-controller in MP3-YSJ 2.0. In MP3-YSS 2.0, the easiness of material management and the social acceptance of music controller & connector needed to improvement. In particular, users felt inconvenience in the social acceptance because of e-textile keypad arrangement. To outweigh this disadvantage, further study is needed about keypad interface of the music controller.

In this paper, we introduce a model of the teaching and learning method for multidisciplinary convergence capstone design at Kongju National University's Engineering Department. At Kongju national University, various capstone design works are designed and proceeded by multidisciplinary students at the summer session. The multidisciplinary approach described in this paper includes the involvement of five department's student who have not collaborated in capstone design experience. This study focuses on multidisciplinary capstone design education by using the micro controller board called Arduino Uno that consists of an assortment of sensors and actuators. The result of self-satisfaction survey was shown the meaningful teaching process for the engineering department students who could have more creative and industrial experiences. As a result, we are able to get the result of the possible directions for future technology education in the area of convergence multidisciplinary capstone design.
