“…The results presented in this paper are based on 12 user tests, which is the suggested average number for such experimentations as shown in previous studies [17,18,19]. All test subjects were either university students or staff with various educational and cultural backgrounds, 7 female and 5 male, aged between 25 and 57.…”

“…The chosen distances of 0.7m, 2.5m and 5m were suggested by the literature as the main focusing distances investigated in previous HUD projection research [17,18,19]. The position (distance to driver) of the HUD plane depends on the test scenario and defines the focal distance and hence the stereo disparity at which the symbol is rendered.…”

Contemporary automotive, navigation and infotainment requirements have evolved the traditional dashboard into a complex device that can often distract the driver. HeadUp Displays (HUDs) have recently attracted the attention in the field of automotive research, promoting the reduction of driver's reaction time and to improve spatial awareness. The aptitude of the proposed HUD interface lies within the driver's focusing ability to the HUD interface and the actual traffic. This paper analyses the performance behaviour through usertests using different focal levels for the projection of a fullwindshield HUD interface. For this purpose, a VR driving simulator has been developed to test the different depths of field configurations of a HUD while driving in various weather and traffic conditions with and without the HUD. Our simulation results reveal the users' preferences regarding the focal point of the superimposed interface and present a comparative evaluation of the different focal levels and their impact on drivers' behaviour and performance.

“…The area of the windscreen that receives the projection is covered with a transparent surface, namely the combiner, which enables the correct depiction of the projected colours and shapes. Depending on the system calibration, the image can be superimposed on the environment, seemingly appearing at approximately 1.5m to 2.5m ahead of the windscreen [12,13]. This is deemed as an ideal projection distance in order to avoid the cognitive capture effect which forces the human eye to focus between two different layers, that in turn results in degradation of human attention and performance [14,15].…”

The paper presents a prototype Head Up Display interface which acts as an interactive infotainment system for rear seat younger passengers, aiming to minimize driver distraction. The interface employs an Augmented Reality medium that utilizes the external scenery as a background for two platform games explicitly designed for this system. Additionally, the system provides AR embedded information on major en route landmarks, navigational data, and local news amongst other infotainment options. The proposed design is applied in the peripheral windscreens with the use of a novel Head-Up Display system.The system evaluation by twenty users offered promising results discussed in the paper.

“…Unfortunately, it is likely that HUDs may not always improve the safety of driving. Research suggests that the HUD advantage may only manifest itself under limited circumstances such as low workload (Larish and Wickens, 1991), simple HUD displays (Okabayashi, Sakata and Hatada, 1991) and under moderate ambient light levels (Weintraub and Ensing, 1992).…”

This document provides an overview of studies investigating the use of HUDs by aviators and drivers, including a summary of HUD research variables, test procedures and study results. The predicted performance advantages of automotive HUDs include increased eyes-on-the-road time and reduced reaccommodation time, particularly for the older driver. To date, the research does not provide robust evidence for operationally significant performance advantages due to HUDs. However, conclusions are equivocal due to the interaction of independent variables such as workload, display complexity and age. Studies indicate that key operator performance issues with HUDs include contrast interference, where HUD symbology masks safety-critical targets in the forward driving scene, and cognitive capture, or degradation of responses to external targets due to the processing of information from a HUD image. In general, the review supports and extends earlier findings that HUD information cannot be processed separately from external roadway information. Countermeasures reviewed in this paper include the use of conformal symbology, and auditory HUDs. The review identifies a number of implementation issues for automotive HUDs: (1) reliable measures of the effect of HUD use on responses to priority external targets must be obtained, under realistic operating conditions; (2) practical considerations of cost, size, and adaptability to a range of driver eye heights figure prominently if the use of HUDs in the private vehicle fleet in the U.S. is to become routine; and (3) driver age and associated visual/cognitive performance differences which are commonly linked to safe vehicle operation must be taken into account during product design, development, and testing. 17.
