Smart physiological sensors embedded in an automobile aaord a novel opportunity to capture naturally occurring episodes of driver stress. In a series of ten ninety minute drives on public roads and highways, electrocardiogram, elec-tromyogram, respiration and skin conductance sensors were used to measure autonomic nervous system activation. The signals were digitized in real time and stored on ...

A Bayesian network decision-making method is proposed by combining driver's eye-tracking data and vehicle-based data together to identify driver lane-changing intents. First, experiments are conducted in a driving simulator with eye-tracker device to obtain the data when a subject driver makes lane-changing maneuvers. Second, collected data are analyzed in machine learning method using Bayesian...

Driver distraction is a high priority topic for NHTSA. NHTSA has concerns that drivers are making potentially dangerous decisions about when to interact with in-vehicle technologies while driving and that this trend may accelerate as new technologies become increasingly available and easier to use. NHTSA has conducted research in the area of driver distraction and workload since 1991. The objec...

The bulk of current haptics human-factors research focuses on mapping basic human perceptual limits. However, many realistic applications demand a better understanding of how to construct more life-like but often less controllable experiment scenarios. In this paper, we study this problem in the context of advanced automobile interfaces. We employ a throttle pedal with programmable force feedba...

Previous literature suggests that haptic gas pedals can assist the driver in search of maximum fuel economy. This study investigated three haptic pedal designs, each with high and low intensities of feedback, in a rapid prototyping, paired comparison design. Twenty drivers took part, experiencing the systems in a high-fidelity driving simulator. Results suggested that drivers were best guided t...

How should we assess the comparability of driving on a road and ‘‘driving’’ in a simulator? If similar patterns of behaviour are observed, with similar differences between individuals, then we can conclude that driving in the simulator will deliver representative results and the advantages of simulators (controlled environments, hazardous situations) can be appreciated. To evaluate a driving si...

Aiming at helping patients bring back some of their lost physical capabilities due to injury or illness, this paper presents a novel gait simulator for their rehabilitation training. It can simulate the normal gait trajectory approximately and guide the patient’s feet to follow the preset trajectory repetitively. The gait simulator was developed based on an end-effector structure equipped with ...

Law enforcement discrimination studies are usually qualified by selection concerns regarding which encounters transpire between individuals and police. This paper overcomes these problems by examining automobile crash investigations by a State Police Department. Because officers are dispatched to investigate crashes on the basis of factors unrelated to driver race, these interactions are effect...

This paper reviews the history of automotive technology development and human factors research, largely by decade, since the inception of the automobile. The human factors aspects were classified into primary driving task aspects (controls, displays, and visibility), driver workspace (seating and packaging, vibration, comfort, and climate), driver’s condition (fatigue and impairment), crash inj...

The work deals with the fatigue analysis of automobile drivers by acquiring their physical signals during real world driving task to determine the driver’s relative stress level. The ECG signals were evaluated using two methods one using time domain analysis and second method using frequency domain analysis. In time domain analysis Pan Tomkins method is used for the detection of QRS complex and...
