In-vehicle displays such as an instrument cluster in a vehicle provide vital information to the user. The information in terms of displays and tell-tales needs to be perceived by the user with minimal glance during driving. Drivers must recognize the condition of the vehicle and the state of its surroundings through primarily visual means. Drivers then process this in the brain, draw on their memory to identify problem situations, decide on a plan of action and execute it in order to avoid an accident. There are visual hindrances seen in real world scenario such as obscuration, reflection and glare on the instrument cluster which prevents the vital information flow from vehicle to the driver. In order to ensure safety while driving, the instrument cluster or driver displays should be placed in an optimized location. This paper deals with how to achieve a visual hindrance free cluster position in a vehicle to protect the important information flow from the vehicle to the driver.
This SAE Aerospace Standard (AS) specifies minimum performance standards for airborne binocular Head-Up Displays (HUDs) in fixed wing (14 CFR part 23, 25) aircraft; while this document is also applicable to rotorcraft (14 CFR part 27, 29) additional performance standards may be required for rotorcraft. This aerospace standard covers basic display standards, but does not include specific application requirements. Specific applications can include flight instrumentation, navigation, engine and system status, alerting, surveillance, communication, terrain awareness, weather, enhanced vision, synthetic vision and other displays. This document covers criteria for conformal and non-conformal HUD systems that are intended for use in the flight deck by the pilot or copilot. Display minimum performance characteristics are specified for standard and other environmental conditions for the purpose of product qualification.
This document applies to both Original Equipment Manufacturer and aftermarket route-guidance and navigation system functions for passenger vehicles. It establishes two alternative procedures, a static method and an interrupted vision method, for determining which navigation and route guidance functions should be accessible to the driver while the vehicle is in motion. These methods apply only to the presentation of visual information and the use of manual control inputs to accomplish a navigation or route guidance task. The document does not apply to visual monitoring tasks which do not require a manual control input, such as route following. Voice-activated controls or passenger operation of controls are also excluded. There are currently no compelling data that would support the extension of this document to in-vehicle systems other than navigation systems.
The scope of this SAE Standard is to provide methods to determine display optical performance in all typical automotive ambient light illumination - with focus on High Ambient Contrast Ratio, which is critical for display legibility in a sunshine environment. It covers indoor measurements and simulated outdoor lighting. It is not the scope of this document to set threshold values for automotive compliance. However some recommended values are presented for reference.
Abstract Current market trend indicates an increased interest in replacing mirrors by camera monitor systems (CMS) to reduce CO2 emissions and to improve visibility of surrounding environment to the driver. A CMS is an advanced system composed of an electronic imager, a display, and an intelligent electronic control unit intended to provide at least the same level of functionality of legally prescribed mirrors. A CMS must also take into consideration several factors in the designed system to satisfy an overall system magnification and system resolution. Some factors pertain to the camera, and display inside the cockpit, but some other are related to the physical constraints of the human operator, i.e. visual acuity, height, etc. In this paper, we demonstrate that there exists a fundamental nonlinear equation for a given CMS encompassing factors that influence the performance of the system.
Abstract The advent of 3D displays offers Human-Machine Interface (HMI) designers and engineers new opportunities to shape the user's experience of information within the vehicle. However, the application of 3D displays to the in-vehicle environment introduces a number of new parameters that must be carefully considered in order to optimise the user experience. In addition, there is potential for 3D displays to increase driver inattention, either through diverting the driver's attention away from the road or by increasing the time taken to assimilate information. Manufacturers must therefore take great care in establishing the ‘do’s and ‘don’t's of 3D interface design for the automotive context, providing a sound basis upon which HMI designers can innovate. This paper describes the approach and findings of a three-part investigation into the use of 3D displays in the instrument cluster of a road car, the overall aim of which was to define the boundaries of the 3D HMI design space.
Artist-Centric HMI Software Development Tool for Reconfigurable Instrument Clusters: Integration with Model-Based Development Tool
Abstract Instrument clusters that display all information on a TFT-LCD screen, also known as reconfigurable instrument clusters, have become the new trend in automotive interiors. DENSO mass-produced the world's first reconfigurable instrument cluster in 2008. To satisfy customer requirements, large quantities of resources were required. Coupled with an iterative process due to requirement changes, development costs became very high. Reducing development costs was vital in order to expand the reconfigurable instrument cluster product line. A new artist-centric HMI (human machine interface) software development workflow is proposed to reduce the development effort by introducing a data converter and real-time 3D rendering engine in our earlier paper. Our goal is to realize an environment with little programming during development by utilizing a tool chain to automate the majority of the programmer's tasks.
This SAE Aerospace Recommended Practice (ARP) addresses the information content for the electronic presentation of data linked weather Meteorological (MET) information used in the cockpit. It defines guidelines for the electronic presentation of MET information (including text, graphics, textures, icons, and symbology) to the flight crew. This ARP is applicable to certified equipment for the electronic display (whether installed or portable) of MET information in the cockpit. This ARP also provides a set of symbols that illustrate the depiction of data linked MET information on flight deck display systems such as Navigation Displays, Multi-function Displays, and Electronic Flight Bags. These recommendations complement standard symbology guidelines for airborne applications already in existence (see reference section for applicable documents).
This SAE standard applies to self-propelled driver operated sweepers and scrubbers as defined in SAE J2130-1. 1.1 Purpose The purpose of this document is to establish the basic requirements associated with controls and displays for dual position driving controls as depicted in a typical installation shown in Figure 1. The control layout illustrated being of a conventional installation as associated with a normal on-road vehicle having a steering wheel to steer the machine and foot pedals to control the speed and braking functions. The document elaborates the requirements for an originally built machine with two driving positions but also where a proprietary commercial truck chassis is converted from a single driving position, it also advises recommendations in design, construction and safety related elements.
Abstract The Instant Mileage Assistance (IMA), as the name indicates, is a system to guide the vehicle users to realize maximum fuel economy (mileage). This system is targeted to provide users with instantaneous mileage indication depending on the current driving pattern, correct gear operating zone (in case of a geared vehicle) through gear up/down shift assist indication and the accurate distance the vehicle can travel before the fuel tank is empty, thereby assisting the user in harnessing maximum fuel economy the vehicle can deliver and also safely reach the next refilling station. The instantaneous mileage is calculated by mapping the distance travelled by the vehicle and the respective amount of fuel consumed, during a particular period of time, and is displayed using an instrument cluster.

Abstract The vehicle environment is known to be a demanding context for efficiently displaying information to the driver. Research in typography reveals some factors that influence reading performance measures, but there is limited research on the influence of typographic design elements in a driver-vehicle interface on user performance with a simulated driver task. Participants in these studies completed a set of vehicle infotainment tasks that involved a text-based item search in a custom-designed interface that employed a family of Helvetica Neue fonts, in a static environment and a driving simulator environment. Analysis of the data from the two studies reveals a modest but statistically significant effect of font on certain driving-related task performance measures. In both studies, fonts with intermediate values of character width and line thickness were associated with the best performance on a simulated driving task.
A Comparison of Three Different Approaches to Image Depth in Driver Information Clusters: 2D Computer Graphics, 3D Computer Graphics and 3D Imaging
Abstract Displays that support complex graphics in driver information (DI) systems allow for the presentation of detailed visual data by employing a range of static (fixed image) and/or dynamic (moving image) design approaches. Such displays are gaining market share across a wide range of mainstream vehicles as the availability and cost of such technologies improves. Although a range of 2D, rendered 3D, and 3D imaging (or stereoscopic) information displays have been demonstrated throughout the automotive industry in recent years, there is limited empirical research examining consumer preference of the respective approaches or their influence on driving related tasks. The vehicle environment is known to be a demanding context for efficiently displaying information to the driver.
The last years have seen an increasing amount of innovations in the functionality of car electronics (e.g. advanced driver assistant systems (ADAS) and in-vehicle infotainment systems (IVIS)). These electrical systems are not reserved for premium cars anymore, but additionally reach mid-size, compact, and subcompact cars. The growing number of functionalities in these cars entails increasing amount of interfaces, which may confuse, overload, or annoy the driver. Accompanying this, there is a trend towards the integration of capacitive touchscreens as user interfaces. These touchscreens were implemented first in consumer electronics and had a substantial impact on the way in which users interact with technology. This in turn has led to an increased user driven demand for the technology to be implemented in other domains, even in safety-critical ones like the automotive area.
Touch-less control coming to cars Use of proximity and gesture-recognition systems in auto cockpits could rise fifty-fold within a decade.

Human Engineering Considerations for Implementing Enhanced Synthetic Vision Systems in Vertical Flight Capable Platforms
The scope of this Vertical Flight document is limited to human behavioral technologies associated with design and/or implementation of Enhanced Synthetic Vision Systems (ESVS) in vertical flight aircraft. Any overlap into logic problems or hardware/software design shall be considered to be incidental to the human factors issues. Where the performance characteristics of specific technologies are relevant they will be identified, and where performance criteria are relevant to specific intended functions/use they will be identified. From a regulatory view, intended function (Full Flight Guidance or Information/Situation Awareness support) has a tremendous effect upon the design of an ESV System. However from a Human Engineering standpoint, the information on display must be discernible and comprehensible to the human operator in both cases and differences may be primarily in information content (required to support a specific task).
