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. When the fuel level in the tank reaches a known threshold, the distance to empty is in turn calculated from the instantaneous mileage value hence providing a more accurate and realistic indication to the user.

This 2014 edition of the Automotive Cockpits and Dashboards Report is the latest in the series of reports by Supplier Business looking at trends and developments in the vehicle cockpit space. Over time we have seen many changes in terms of the design and structure of the main modules and components that go to make up the dashboard and cockpit element of the vehicle’s interior. In particular the increasing level of in-vehicle connectivity has caused interior designers to rethink the layout and content of the dashboard and center console. In this report the main trends and developments are highlighted, with particular reference to examples of the way in which the industry has responded to the challenge. The strongest influence on the vehicle’s cockpit and dashboard continues to be the requirement for in-vehicle connectivity. Consumer demand for seamless connectivity between home, office and vehicle dominates the cockpit’s interior design and structure. The technology required to provide the level of connectivity demanded by users is increasingly complex and, by necessity, has to embrace advanced driver active safety systems (ADAS) and the anticipated development of semi-autonomous and ultimately, fully autonomous vehicles.

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. Research in 3D [1, 2] reveals some of the factors that influence its acceptance and effective use, but there is limited research on the effects of 3D-related design elements when used in a driver-vehicle interface.

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. The results of this study suggest that using typefaces with intermediate values of certain intrinsic design factors may serve as a simple and effective means of improving vehicle user interfaces.

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. Capacitive touchscreens have certain drawbacks in their distraction potential and their usability, leading to safety-critical situations and negative user feedback.

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). The document is independent of candidate technologies and concentrates on human interface criteria.

ARP4101/1A
This document establishes the minimum requirements for seats and restraint systems for the flight deck. Due to limitations that it would place upon basic aircraft design, it is not considered practical for these requirements to apply fully to the observer seat. However, it is emphasized that every effort should be made to provide the observer seat position with an equivalent level of comfort and safety. This document is also intended to make recommendations for flight crew restraint systems. A properly designed crew restraint system will mminimize injury or debilitation during a survivable crash and enable post crash assistance to occupants and escape from the aircraft. Crew member safety is the primary objective, with appropriate provisions for crew comfort taken into consideration. The criteria established herein are designed to standardize restraint systems without hindering the development of new, improved systems.
