Recently, the traditional rear and side view mirrors have been started to be exchanged with a digital version. The aim of this study was to investigate the difference in driving performance between traditional rear-view mirrors and digital rear view mirrors which is called Camera Monitor System (CMS) in the vehicle industry. Here, two different types were investigated: CMS without or with Augmented Reality (AR) Information. The user test was conducted in a virtual environment, with four driving scenarios defined for testing. The user test results revealed that the participants driving performance using CMS (only cameras and 2D displays without augmented information) did not improve over traditional mirrors.
This paper presents some key new display technologies that are finding increased use in automotive applications and describes the integration challenges and some user aspects of these technologies in the context of automotive use.
Vehicles are becoming “smarter” year by year with regards to increasing levels of digitalization, electrification, sensing, computing power and autonomy. Displays play a central role in this “smartification” of the vehicle as the primary visual interface between the vehicle and the driver. In addition to currently ubiquitous in-vehicle display applications and interactions, new ones are emerging. How will current and new in-vehicle display applications and interactions impact the driver (and passenger) experience? In this paper, some technical and perceptual aspects of this will be reflected upon and some projections be made.
This paper introduces a new approach to evaluate the influence of anti‐reflective and anti‐glare surface treatments on the readability of automotive displays. A car simulator was equipped with an illumination setup to mimic real ambient light scenarios. During the experiments we measured the ability of the driver to collect information from the display while driving. Our results validate this approach and demonstrate that the choice of surface treatment depends on the scenarios considered by the car manufacturers.
A well‐known drawback with LCD‐displays in cold is a slow pixel response leading to poor picture quality. Low temperatures can constitute a hazard in viewing important displays in cars. Perceptual experiments with 20 test‐persons were conducted to find clear and acceptable ranges on screens simulating distortions in low temperatures. The results showed perception over clear and acceptable image quality was impaired beyond ‐20°C for the LCD‐screen in the experiments.
This paper describes how “pixels on the road” have grown by the numbers over the past decade and provides a personal outlook on where they are headed in the coming years.
This paper presents current automotive display market trends and display technologies for automotive use.
The nature of the automotive industry is changing as Connectivity, Autonomous Drive, Shared Mobility concepts and Electrification take center stage in this new decade. This transformation will drive some unique needs and present some interesting challenges in the years ahead. In this paper we will explore how the User Experience, and the HMI technologies that enable it, will define how we perceive the future of mobility.
Many developments within Connectivity, Autonomous driving, Shared mobility and Electrification (“CASE”) are expected in the automotive industry as it enters the next decade. Several different enabling technologies are required for this, such as wireless communications and antenna technologies for Connectivity; advanced sensor technologies such as radar, camera, and lidar, as well as advanced software such as artificial intelligence, for Autonomous Driving; fleet management, service bookings, subscription plans for Shared Mobility; and, advanced battery technologies, electric powertrains and charging infrastructure for Electrification. However, without a user interface to manage all these features, they will be cumbersome or impossible to use. In this paper, we describe how the case is building for display technology, as a key enabler for all these developments.
The following topics are dealt with: thin film transistors; semiconductor thin films; indium compounds; amorphous semiconductors; zinc compounds; gallium compounds; elemental semiconductors; organic light emitting diodes; silicon; and solar cells.
The ever‐increasing need for displaying in‐vehicle visual information in a non‐distracting way requires a high visual performance of automotive displays. For their procurement, deep technical and supply‐chain knowledge is required. Therefore, based on our comparisons of in‐vehicle and laboratory visual‐performance measurements, we propose a certification system for automotive display panels.
Many devices, such as tablets, smartphones, notebooks, fixed and portable navigation systems are used on a (nearly) daily basis, both in in- and outdoor environments. It is often argued that contextual factors, such as the ambient illuminance in relation to characteristics of the display (e.g., surface treatment, screen reflectance, display luminance …) may have a strong influence on the use of such devices and corresponding user experiences. However, the current understanding of these influence factors is still rather limited. In this work, we therefore focus in particular on the impact of lighting and display luminance on readability, visual performance, subjective experience and preference. A controlled lab study (N=18) with a within-subjects design was performed to evaluate two car displays (one glossy and one matte display) in conditions that simulate bright outdoor lighting conditions. Four ambient luminance levels and three display luminance settings were combined into 7 experimental conditions. More concretely, we investigated for each display: (1) whether and how readability and visual performance varied with the different combinations of ambient luminance and display luminance and (2) whether and how they influenced the subjective experience (through self-reported valence, annoyance, visual fatigue) and preference. The results indicate a limited, yet negative influence of increased ambient luminance and reduced contrast on visual performance and readability for both displays. Similarly, we found that the self-reported valence decreases and annoyance and visual fatigue increase as the contrast ratio decreases and ambient luminance increases. Overall, the impact is clearer for the matte display than for the glossy display.
