As the main cause of car accidents is driver distraction, HUD utilization is important to boost drivers' front-observing. Recently, As HUD includes a variety of contents products have appeared on market, the possibility increases cognitive load while driving. The purpose of this study is that currently being used HUD contents how much affect drivers while driving. To investigate about it, the experiment is examined cognitive aspect with utilization aspect of different gender and illuminance environment. The study provides, in accordance with the internal and external illuminance, the visibility make a difference. The gap between the internal and external illuminance is higher, the visibility is better. Also, this study confirms that HUD's awareness of contents depends on driving information. Drivers concentrate more on higher related driving contents than lower ones.

In this paper, we describe a design and development of car HUD(Head-Up-Display) navigation system using a Raspberry Pi. Car drivers can't concentrate on driving due to the use of various electronic devices, especially the car navigation systems installed in the cars. Therefore, car accident caused by not concentrating on the driving views is one of the most common accident types. In order to prevent the problems, HUD technology is used to help the driver to secure front views, thereby to minimize the traffic accidents caused by neglecting forward views. In this research, we propose the design and development techniques of a HUD navigation system using Raspberry Pi, and we believe that the commerical use of HUD navigation will grately reduce the risk of many car accidents.

A Head-Up-Display is an avionic equipment to identify targets and flight data at same time the pilot looks over the external environment outside canopy. The HUD displays various symbols to depend on avionic mode which is composed of navigation mode, air-to-air mode, air-to-ground mode. In air-to-air mode, HUD should provide the intuitive symbols for pilot to aim the target exactly in a short time. In this paper, we propose a design method to improve the visibility of the HUD Symbols.

자동차 HUD(Head-Up Display)는 기존 HDD(Head-Down-Display)로 인한 운전자의 시선 분산을 줄이기 위한 장치로, 기술개발뿐만 아니라 관련 상용 제품이 다수 출시되고 있으며 HUD를 장착한 차량도 국내외에서 다수 선보이고 있다. 최근에는 대면적 디스플레이를 통하여 실 세계의 다양한 정보를 운전자의 시야를 중심으로 제공하는 증강현실 기술이 적용된 HUD가 차세대 정보제공 장치로 주목받고 있으며 국내외에서 관련 기술개발이 진행되고 있다. 본고에서는 HUD를 구현하기 위한 주요 방식별 특징을 살펴보고 자동차 적용 동항에 대해 논의 하고자 한다.

PURPOSES: In this study, as part of an effort to develop HUD for public transit, it is proposed that the decision of order priority of contents which will be disposed to bus drivers through HUD for public transit using AHP(Analytic Hierarchy Process) technique. METHODS: In AHP analysis method brainstorming, factor analysis, hierarchical structuring, and weighting analysis were performed by applying a classical analysis method. RESULTS: By the result of analysis it is shown that unlike car drivers, bus drivers prefer information related to bus intervals, bus stop, and door open and close to information related to vehicle running. Also, bus stop information and bus interval information were ranked as first and second place in order priority of HUD contents for public transit by experts. CONCLUSIONS: This method of selecting order priority of HUD contents for public transit can provide a basic foundation for selecting order priority of traffic information contents as well as other HUD contents.

Most car accidents occur when the driver does not look at the lane. Specially When the driver needs to find the path through the navigation, the driver have to look the other site. The number of such accidents can be prevented, if the driver receives the information without gazing other spot during the car is running. HUD (Head-Up Display) Technology, developed for enhancing the combat effectiveness and pilot's visibility in fighter, is applied to luxury cars for the safe operation of the driver. In recent years, the simple speed, lubrication status etc., as well as navigation information also shows through HUD. HUD is expected to increase in the future. But these HUD show the information elsewhere in the driver's eye focus. It is necessary to focus on the windshield for a few msec to check the information. In this paper, Introduced method display the HUD information in 3D as well as in similar distance the driver's eye focus so that the driver can operate the car more safely.

Virtual reality seems to be the center of the next generation platform, which is founded on various engines that can easily make device progress and content. However, the interaction between virtual reality contents and users is thought of as relatively requiring technological advances. In this paper, we propose a technique to improve the interaction technique based on the case of Virtual Figure Model Crafting (VFMC) to analyze the problem of interaction caused by virtual reality contents. We introduced the concept of Head-Up Display (HUD) to present a more natural interaction method. The HUD is the digital visual interface of the aircraft. The advantage of HUD visual interface is to minimizes the user's visual movement by displaying the information of the scattered view to the forward direction of the pilot. In other words, we can reduce unnecessary left and right movements that make it is possible to expect an effect of reducing fatigue and increasing immersion.

In the semi-autonomous vehicle, before reaching a fully autonomous driving stage, it is imperative for the system to issue a take-over request(TOR) that asks a driver to operate manually in a specific situation. The purpose of this study is to compare whether head-up display(HUD) is a better human-vehicle interaction than head-down display(HUD) in the event of TOR. Upon recognition of TOR in the experiment with a driving simulator, participants were prompted to switch over to manual driving after performing a secondart task, that is, playing a game, while in auto-driving mode. The results show that HUD is superior to HDD in 'ease of use' and 'satisfaction' although there is no significant difference in reaction time and subjective workload. Therefore, designing secondary tasks through HUD during autonomous driving situation improves the user experience of the TOR function. The implication of this study lies in the establishing an empirical case for setting up UX design guidelines for autonomous driving context.

본 연구에서는 뇌파를 이용하여 자동차에 HUD를 적용하였을 때, HUD의 위치와 이미지 컬러 변경 시 뇌 활성화 지수(Brain Activity Quotient)의 변화를 관찰하였다. 뇌파데이터는 Fp1, Fp2, O1, O2 총 4채널에서 얻었고, HUD위치는 좌측, 중앙, 우측으로 구성하였고 컬러는 초록, 주황, 빨강 총 3가지 색상을 사용하였다. HUD이미지의 크기는 $8{\times}4.5cm^2$로 구성하였다. 뇌 활성화 지수는 상대파워분석(Relative power analysis)를 사용하여 Slow beta wave(13~20 Hz)/alpha wave(4~7.99 Hz)로 계산하였다.
