The aim of the study is to find enhancements of the user experience for HUD in vehicles. This has been done by building a working HUD graphical user interface (GUI) prototype with the Qt framework from requirements gathered from interviews, focus groups and competitor analysis. The prototype was field tested in a Volvo XC90 which gave rise to a concept for how to increase the user experience for HUD. The results from the evaluation of the prototype confirms that the user experience can be enhanced with a more modern interaction, focus on usability and functionality, and by keeping the information amount at a modest level while the driver focuses on the road. The conclusion is that enhancing the HUD will enhance the overall user experience allowing the driver to minimize the perceived inattention, secondary tasks and gain better situational awareness. This is archived by moving functionality to the HUD from the other information sources within the vehicle and by displaying the information with design adapted to the HUD. The prototype has received great feedback from key stakeholders both internally and externally. The next step is to perform longer tests and in addition to develop functionality to find the perfect balance between information visualization and safety.

About 90% of the accidents occur due to human errors [2] [3] such as bad awareness, distraction, drowsiness, low training, fatigue etc. These human errors can be minimized by using advanced driver assistance system (ADAS) which actively monitors the driving environment and alerts a driver to the forthcoming danger, for example adaptive cruise control, blind spot detection, parking assistance, forward collision warning, lane departure warning, driver drowsiness detection, and traffic sign recognition etc. Unfortunately, these systems are provided only with modern luxury cars because they are very expensive due to numerous sensors employed. Therefore, camera-based ADAS are being seen as an alternative because a camera has much lower cost, higher availability, can be used for multiple applications and ability to integrate with other systems.

  • Using Head-Up Display for Vehicle Navigation
    DESCOMPOSING THE MAP: USING HEAD-UP DISPLAY FOR VEHICLE NAVIGATION Dane Harkin, William Cartwright, and Michael Black School of Mathematical and Geospatial Science RMIT University, Melbourne, Australia ABSTRACT The mobility of people is ever increasing, with a sense of being able to travel to any destination they wish. Utilising the GPS and computer technology created for the use within vehicles for guidance purposes allows people to do this, without the thought of Where am I? or Where do I go now? These systems warrant the need to look at the display for excessive periods of time, causing drivers to remove their vision from the road. A possible solution could be the introduction of military aviation technology, specifically Head-Up Display (HUD), to compliment the current system, by presenting modified navigational information on the windscreen. This paper looks at background theory associated with the technology being investigated and its proposed implementation. It then provides an overview of the information obtained to date. Problems that may occur with such an implementation are discussed and further research to be undertaken outlined. INTRODUCTION Since the introduction of the first motor vehicle, crafted independently by Germany’s Gottlieb Daimler and Carl Benz in 1886 (Mercedes-Benz, 2003), there has been a general improvement in personal mobility. The motor vehicle allowed people to travel to destinations of choice, and they usually navigated there with the aid of a map or map book. Over the years, navigation tools improved as new cartographic techniques were developed and employed. During the 1970s, “… efforts to develop in-vehicle route guidance systems were initiated” (Adler and Blue, 1998, p.

  • Development of an Automotive Head-Up Display Using a Free-Form Mirror Based Optical System
    Development of an Automotive Head-Up Display using a Free-Form Mirror Based Optical System Kodai FUJITA*，Kenji ITO*，Kazuya YONEYAMA*，Tomoyuki BABA*，Masanao KAWANA*， Keisuke HARADA*，and Hiroyuki OSHIMA* Abstract In June 2013, the Optical Devices Division (Former Fujinon) and Electronic Imaging Division were integrated to establish the Optical Device & Electronic Imaging Products Development Center. This collaboration enabled us to develop a novel Head-Up Display (HUD) system for automotive devices. We adopted a newly designed free-form mirror system. By the mirror system, we were able to simultaneously realize following features in our HUD system: distortion-less large virtual images, high brightness/ contrast, and small unit size. Herein, we report the development results related to this HUD system. 1. Introduction sons. One is expectation of market growth.

  • Head up Display Techniques in Cars S
    Z ISSN: 2319-5967 ISO 9001:2008 Certified International Journal of Engineering Science and Innovative Technology (IJESIT) Volume 4, Issue 2, March 2015 Head up Display Techniques in Cars S. M. Mahajan, Sudesh B. Khedkar, Sayali M. Kasav Abstract— Head-up displays (HUD) are partially-transparent displays that render information in a manner that allows the viewer to comprehend it while looking into the forward scene. It is known as Head up display because while using it the operator’s head position is UP means forward instead of looking down. The technology of HUD is mainly used in AVIATION industry, but now it has various applications in cars also. HUD can be fitted in place of windscreen which will give the view of road plus the required information. HUD is the outcome of GPS and compass based data about a vehicle position and the emergence of computer vision technology that can recognize objects on and around the road and the navigational information as transparent colored paths. Head up displays (HUDs) are available in aircraft industries from a long time and they are now finding way into automotive industry also. This review is an attempt to study various types of techniques in which head up display is used in cars. Because the application of HUD technology to automobiles is a relatively new idea, it is hoped that this review will serve not only an assessment of the current state of automotive HUDs but also an foundation upon which future work can be based. Many assessments of HUD location have been made but still there is not a optimal HUD location.

Abstract To design automotive head up displays, the extent to which HUDs interfere with detection of elements of the road scene (other vehicles, edge markings, signs, etc.) as a function of HUD location needs to be determined. In this experiment, 24 subjects sat in a driving simulator and watched a videotape of a real road. To encourage them to scan the road as they would while actively driving, subjects pressed a key whenever they detected predetermined events in the road scene (passing cars, tail lights of a leading vehicle, road signs on the right edge of the road).
