Given the sometimes disparate findings and the increasing application of AR in both training and operations, as well as increased affordability and availability, it is important for researchers, user interface and user experience (UI/UX) designers, and AR technology developers to understand the factors that impact the utility of AR. To increase the...

Transportation Security Officers (TSOs) are at the forefront of our nation’s security, and are tasked with screening every bag boarding a commercial aircraft within the United States. TSOs undergo extensive classroom and simulation-based visual search training to learn how to identify threats within X-ray imagery. Integration of eye tracking techno...

This paper presents a novel approach to diagnosing and measuring teamwork in complex sociotechnical systems. First, the underlying theoretical constructs that have inspired the development and use of a multi-level model to study team phenomena from a general systems perspective are presented. Next, in an attempt to theoretically ground the construc...

X-ray image analysis and interpretation of carry-on items at airports is a primary responsibility for security personnel. This task is one of the most difficult and critical in ensuring the safety of commercial air travel for the public. There are several factors that contribute to the difficulty. X-ray imaging aptitude testing (X-APT) is focused o...

This paper presents a novel approach to diagnosing and measuring team resilience in sociotechnical systems. This approach is based on a multi-level model developed to study team phenomena from a general systems perspective. We will describe a methodology that uses a concept similar to flow within the psychological literature to measure a team's res...

Visual search is a complex task that involves many neural pathways to identify relevant areas of interest within a scene. Humans remain a critical component in visual search tasks, as they can effectively perceive anomalies within complex scenes. However, this task can be challenging, particularly under time pressure. In order to improve visual sea...

X-ray images provide information about the inner structure of the object and depict density, whereas photographs created by light reflection provide information about an object's surface. Thus, X-ray screeners rely on a very different set of perceptual cues and strategies to recognize objects and potential threats. Also, the X-ray detection task is...

Effective training is a vital foundation for transportation security officers required to learn strategies for identifying anomalies within X-ray images that may indicate a potential threat. Past research has shown that adaptive training is a powerful tool to increase detection performance, however, adaptive training strategies in this domain have...

Recent investigations of loudness change within stimuli have identified differences as a function of direction of change and power range (e.g., Canévet, Acustica, 62, 2136–2142, 1986; Neuhoff, Nature, 395, 123–124, 1998), with claims of differences between dynamic and static stimuli. Experiment 1 provides the needed direct empirical evaluation of l...

Beyond obvious differences, there are many similarities in the challenges faced in studies of speech and natural (nonspeech) sounds. The source events are dynamic, complex and highly variable. Source properties map only statistically in the sounds produced, resulting in many acoustic properties that are only sometimes accurate indicators of specifi...

Recent investigations of loudness change across dynamically varying stimuli have identified differences between increasing versus decreasing power that depends upon stimulus complexity and intensity range [e.g., Canevet, Acustica, 62, 2136-2142 (1986); Neuhoff, Nature, 395(6698), 123-124, (Sep 1998)]. Some explanations of these findings are based u...

There is a small but growing literature on the perception of natural acoustic events, but few attempts have been made to investigate complex sounds not systematically controlled within a laboratory setting. The present study investigates listeners' ability to make judgments about the posture (upright-stooped) of the walker who generated acoustic st...

Psychophysical investigations dating back more than half a century have examined relationships between physical sound properties and listener perception of changes in single dimensions of sound with the goal of understanding normal listening. Recently, a need has developed to expand the understanding of single dimension sound to more complex natura...

Natural auditory events are complex. In perceiving these events, listeners tend to use various, and not necessarily optimal, samplings of information. Prior research examined static and dynamic source and sound characteristics for a posture contrast (upright versus stooped) in human gait, identifying several acoustic cues that sometimes differentia...

One ultimate goal of auditory research is to understand how we perceive natural events. In our conceptualization, there are three component stages to auditory event perception: the source event, the sounds produced, and perception of the event. The current study carefully examines each of these three components, and the inter-relationships among th...
