Objective: The paper aims to integrate interior and exterior sensing signals to explore gaze-context connections for more context-aware driver attention management. Background: Driving context is important for crash risk assessment, but little is known about how it modulates attention requirements for developing driver monitoring systems. Method: T...

Objective The study aims to model driver perception across the visual field in dynamic, real-world highway driving. Background Peripheral vision acquires information across the visual field and guides a driver’s information search. Studies in naturalistic settings are lacking however, with most research having been conducted in controlled simulati...

Head pose has been proposed as a surrogate for eye movement to predict areas of interest (AOIs) where drivers allocate their attention. However, head pose may disassociate with AOIs in glance behavior involving zero or subtle head movements, commonly known as “lizard” glance pattern. In contrast, “owl” glance pattern is used to describe glance beha...

Objective Research shows frequent mobile phone use in vehicles but says little regarding how drivers hold their phone. This knowledge would inform countermeasures and benefit law enforcement in detecting phone use. Methods 934 participants were surveyed over phone-use prevalence, handedness, traffic-direction, and where they held their device. Re...

Objective This study aimed to investigate the impacts of feature selection on driver cognitive distraction (CD) detection and validation in real-world nonautomated and Level 2 automated driving scenarios. Background Real-time driver state monitoring is critical to promote road user safety. Method Twenty-four participants were recruited to drive a...

Contextual investigations of automated vehicle technology have so far been rare, however they are crucial to uncover the challenges that exist around its acceptance and safe use. Twenty-one drivers used a partially automated vehicle on a public highway in unaltered traffic conditions, while their behaviour was observed. Subjective measures of techn...

Vehicle automation will fundamentally change what it means to safely operate a vehicle. Future vehicles will afford the driver opportunities to decrease their active control of the vehicle through taking their hands off the wheel and taking their eyes and mind off the road. The components of the driving task, and thus driver behavior and expectatio...

ii ABSTRACTVibrotactile displays are advantageous in task environments where visual and auditory channels are saturated or environmentally undesirable. These immediate, private stimuli are tied to our cognitive embodiment and well-suited for providing physical directions and speeded signals under cognitive workload and reducing competition for shar...

Objective: This research analyzed the effects of weather technology interface characteristics on the quality and timeliness of weather-related decision making via mental workload and situational awareness (SA) metrics using flight training devices (FTDs) and follow-up in-flight validation testing. Background: A significant number of fatal general a...

As part of the Nuclear Regulatory Commission’s recertification of Texas A&M University’s AGN-201M nuclear reactor, a human factors analysis was performed to evaluate the drawbacks of the current system and make design recommendations for a new console layout. The process involved three phases. Background development consisted of a literature review...

Vibrotactile communication technologies are viable candidates for the replacement of more traditional radio communication technologies, particularly in domains where visual and auditory resources are either inconvenient or in high demand. Of particular interest is the potential for improved speeded communications, to allow those directing to direct...

In-vehicle driver distractions are an increasing cause of automobile accidents. Recent advances in wearable consumer technologies impose new challenges for managing driver attention and regulating device use in the driving context. Google Glass is a wearable interface that presents information via a heads-up display and read aloud function, neither...

Recent research has shown that haptic displays are particularly well-suited to communicating navigation information, but these displays are rarely evaluated in situations that require time-critical communications. The present study serves as the first proof of concept for “CHIAD”: a new haptic interaction system that allows fast and efficient commu...

The sense of touch is uniquely well-suited for displaying certain types of information, such as navigation instructions and some high-level messaging. As part of a line of research in developing a vibrotactile communication system to support person-to-person tactile messaging over a network, the present study examines the effectiveness and efficien...
