Where do people drive? navigation system use by typical drivers and auto experts / Victor Ei-Wen Lo, Paul A. Green, and Alfred Franzblau.
To effectively design navigation and travel information systems, car manufacturers need data on how these systems are typically used. In this study, researchers surveyed thirty typical drivers and eleven auto experts to determine previously visited destinations, favourite destinations, and other...
Development and evaluation of new anchors for ratings of driving workload
Older drivers stop driving for several reasons, including being overwhelmed by the workload of the primary driving task. Unfortunately, most driving studies (including those measuring driver distraction and overload) describe workload qualitatively, not quantitatively. A simple way to quantify...
Estimating the legibility of a single letter E viewed at different display angles
Text is often viewed not perpendicularly to its display. With nine assumptions, this study developed a new equation for estimating the legibility of a single letter E viewed at different display angles. This equation examines viewing distance, text height, strokewidth, Snellen acuity, background...
Evaluation of a navigation radio using the think-aloud method
In this experiment, 13 licensed drivers performed 20 tasks with a prototype navigation radio. Subjects completed such tasks as entering a street address, selecting a preset radio station, and tuning to an XM station while -thinking aloud- to identify problems with operating the prototype interface...
Legibility index for examining common viewing situations a new definition using solid angle.
The legibility levels of text and graphics can be assessed using the Legibility Index, conventionally defined as the distance at which material can be read with perfect accuracy (the legibility distance) divided by the character height. The ratio equals the inverse tangent of the visual angle...
Effects of time-gap settings of adaptive cruise control (ACC) on driving performance and subjective acceptance in a bus driving simulator
A study was conducted to investigate the effects of time-gap settings and contents of secondary tasks on a fix-based bus driving simulator on drivers- performance while reclaiming control from ACC in a car-following scenario of emergency brake by the lead vehicle. Thirty professional bus drivers...
Development and evaluation of automotive speech interfaces: useful information from the human factors and the related literature.
Drivers often use infotainment systems in motor vehicles, such as systems for navigation, music, and phones. However, operating visual-manual interfaces for these systems can distract drivers. Speech interfaces may be less distracting. To help designing easy-to-use speech interfaces, this paper...
