A driving simulator experiment was conducted to determine the effects of entering addresses into a navigation system during driving. Participants drove on roads of varying visual demand while entering addresses. Three address entry methods were explored: word-based speech recognition, character-based speech recognition, and typing on a touch-screen(More)
In this study 24 participants drove a simulator while listening to three types of messages in both synthesized speech and recorded human speech. The messages consisted of short navigation messages, medium length (approximately 100 words) email messages, and longer news stories (approximately 200 words). After each message the participant was presented with(More)
Cardiac (heart rate, pre-ejection period, and respiratory sinus arrhythmia), performance, and visual demand measures of driver workload were obtained from 15 male university students who drove a simulated course multiple times at a fixed speed of 72.4 km/h. The course contained curves of 3 different radii (582, 291, and 194 m) and was driven with and(More)
Perceptual mapping is widely used in marketing to analyze market structure, design new products, end develop advertising strategies. This article presents theoretical arguments and empirical evidence which suggest that factor analysis is superior to discriminant analysis and similarity scaling with respect to predictive ability, managerial interpretability,(More)
The driver/rider experience is a major development in mobile user-interface (UI) design worldwide, similar in scale to the first introduction of personal computers to the desktop. Most automobile manufacturers seeking to develop smart cars have relatively little experience with advanced software-based UIs and information visualization (IV). This panel(More)
This paper summarizes Society of Automotive Engineers (SAE) Recommended Practice J2944, Driving Performance Measures and Statistics (draft of February 12, 2013). This Practice was written because commonly used measures and statistics are (1) not named consistently (a lane departure is also called a lane exceedance, lane bust, line crossing, etc.), (2)(More)
This paper describes the modifications to free, open-source driving simulator software to simulate a car-following task resembling that in the NHTSA driver distraction protocol. In brief, the peak-to-peak amplitudes of the lead vehicle were sharply reduced (to 70% of the specified values) and made more uniform. In addition, the mean speed was reduced by 10(More)
This paper describes how referring to and using test methods and conditions specified in recognized standards and guidelines from the International Organization for Standardization (ISO), the Society of Automotive Engineers (SAE), U. S. Department of Transportation (US DOT), the International Telecommunications Union (ITU), and other organizations can(More)
