홀로그래피 HUD의 제작에 필요한 주요 파라미터를 살펴보고 이들 값을 결정하기 위한 관계식을 유도하여 설계 값을 설정하였다. 기록 방법으로는 간섭무늬에 의한 잡음을 최소화할 수 있는 공기층 반사 기록방법을 제시하였다. 특히, DCG필름을 처리한 후에 생기는 중심파장의 이동을 보정하기 위한 새로운 방법을 소개하였다.

대부분의 현대 항공기 조종실은 유사한 형태인 HUD, 2개 이상의 MFD, UFC, HOTAS 등으로 구성된다. 앞에서 언급한 바와 같이 최근에는 전투기에도 HMD와 DVI(Direct Voice Input)를 적용하고 있다. 미래의 조종실은 빠르게 발전하고 있는 평면 시현 기술로 인해 HDD는 2010년대에는 15 X 20인치 크기까지 지원이 가능할 것으로 예상되며 HUD가 없어지고 높은 해상도가 넓은 시계영역을 가진 HMD가 없어지고 높은 해상도와 넓은 시계영역을 가진 HMD로 다중 운용(Joing Service Operability) 및 다중 임무 수행이 가능한 조종실이 될 것이며 2025년대에는 레이저 운용에 적합한 조종실로 변화되어 캐노피가 없는 조종실(Windowless Codkpit) 또는 불투명 HMD를 사용한 설계개념으로 발전할 것이다.

We propose a hand gesture recognition method that is compatible with a head-up display (HUD) including small processing resource. For fast link adaptation with HUD, it is necessary to rapidly process gesture recognition and send the minimum amount of driver hand gesture data from the wearable device. Therefore, we use a method that recognizes each hand gesture with an inertial measurement unit (IMU) sensor based on revised correlation matching. The method of gesture recognition is executed by calculating the correlation between every axis of the acquired data set. By classifying pre-defined gesture values and actions, the proposed method enables rapid recognition. Furthermore, we evaluate the performance of the algorithm, which can be implanted within wearable bands, requiring a minimal process load. The experimental results evaluated the feasibility and effectiveness of our decomposed correlation matching method. Furthermore, we tested the proposed algorithm to confirm the effectiveness of the system using pre-defined gestures of specific motions with a wearable platform device. The experimental results validated the feasibility and effectiveness of the proposed hand gesture recognition system. Despite being based on a very simple concept, the proposed algorithm showed good performance in recognition accuracy.

오토바이는 자동차에 비해 차량주행정보가 부족하고 사고 위험성이 높아 충돌감지센서, 후방카메라, 블루투스 통신모듈, 마이크로콘트롤러, HUD로 구성되는 스마트헬멧을 제작하여 오토바이 주행정보와 e-call 기능을 제공하는 시스템을 개발한다면 사용자에게 매우 유용하고 교통사고 시에 인명피해 감소 및 신속한 교통사고 처리가 가능하다. 본 논문에서는 이와 같은 "스마트헬멧을 이용한 오토바이 운전자 주행정보 및 e-call 기능 제공 시스템"의 소프트웨어를 개발하는데 있어 객체지향 분석 방법인 UML을 이용한 소프트웨어 개발 분석 방법, 하드웨어 블록다이어 그램 구조, 플로우차트 및 UI 설계를 보여줌으로써 실무 개발에 적합한 분석/설계 방법을 제시하고자 한다.

Objectives: This study aimed to investigate the efficacy of postoperative submucosal injection of hyaluronidase (HUD) for reducing sequelae and quality of life (QOL) after mandibular third molar (M3M) surgery. Materials and Methods: Participants with bilateral impacted M3M underwent surgical extraction with a split-mouth randomized controlled study design. M3M were removed by the same surgeon in 2 sessions, one a control and the other experimental. Submucosal injection of HUD was performed in the experimental session and submucosal injection of saline in the control session. Mouth opening, facial swelling, and pain intensity were measured before surgery, and then 2 and 7 days after surgery. The QOL of participants following surgery was evaluated by means of a patient-centered outcome questionnaire (PCOQ). Results: A total of 36 patients was included in the final data analysis. There was a significant reduction in the maximal mouth opening and postoperative pain in the experimental side at the 2 and 7 days after surgery (P<0.05), and a remarkable difference in facial swelling was reported on the experimental side 7 days after surgery (P<0.05). The PCOQ demonstrated that participants reported less pain and swelling on the experimental side. Conclusion: The present study provides clinical evidence that submucosal administration of HUD immediately after M3M surgery reduced postoperative discomfort and improved patients' QOL.

The Paper presents some potential new uses for Head-Up Displays (HUDs) in vehicular applications, where the information conveyed to the driver goes well beyond the content of today's production HUDs. Such information potentially related to the use of cellular telephones, navigation systems, vehicle to roadside communications systems, and many others. Improvements in flat panel display technologies are enabling the presentation of larger, more reconfigurable, more daylight-viewable HUD images. In addition, A Formal test and evaluation is proposed to ensure that new information displays support the driver tasks. The above developments suggest increased future opportunities for HUDs to present useful information in an as-needed, eyes-on-the-road manner.

We have succeeded in designing a PHUND (portable head up navigation display), which has a compact system with a MD panel and full color display device using RGB LED sources. The PHUND has been developed as an alternative to conventional built-in type HUD system targeting the high volume aftermarket with an affordable price.
