Article
Full-text available
Failure to fully consider human factors issues at all stages of system development can increase costs and delay system deployment. The System for Human Factors Assessment and Readiness Evaluation (SHARE) is a conceptual framework that includes a method for standardizing human factors readiness assessment. SHARE utilizes a Human Factors Readiness Le...

The sensitivity of a game-based neurocognitive test to detect sleepiness and fatigue among workers at an airport passenger screening checkpoint (screeners) was examined. Screener fatigue and sleepiness was evaluated using both the game-based test and self-reports over the course of an eight-hour shift. Fatigue and sleepiness using the game-based te...

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...

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...
Conference Paper
While human factors has been recognized as a key component in research and development efforts, there is a lack of systematic guidance as to how to insert human factors evaluation outcomes into system development processes. The current effort proposes a systematic scale comparable to existing Technology Readiness Level scales to objectively quantif...

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...
Conference Paper
The purpose of this study was to assess at a preliminary level, the test/retest reliability of the math processing mini-game of CogGauge: a cognitive assessment tool for spaceflight. The focus of this assessment was on the stability of test scores and calculation of reliable change on test/retest scores obtained on a mathematical processing task. A...
Article
The System for Tactile Reception of Advanced Patterns (STRAP) is capable of displaying complex information through tactile actuators on a user's torso. Non-verbal communication requirements from a Military Operations in Urban Terrain (MOUT) task and tactile design guidelines resulted greater than 60 distinct tactile symbols for communication and a...
Conference Paper
Unmanned aerial systems (UAS) have high mishap rates as compared to general aviation. Among other factors, UAS operator error has been associated with instrumentation/sensory feedback systems and channelized attention. Multimodal displays, and in particular exteroceptive tactile cueing may be a useful means of compensating for UAS operator's sensor...

Article
Augmented cognition is a form of human-systems interaction in which a tight coupling between user and computer is achieved via physiological and neurophysiological sensing of a user's cognitive state. This interactive paradigm seeks to revolutionize the manner in which humans engage with computers by leveraging this knowledge of cognitive state to...
Article
This paper describes the Training Effectiveness Evaluation with neurophysiological metrics: Fidelity Assessment of VE Training Systems (TEE-FAST) framework, which offers a comprehensive assessment of physical, functional and psychological fidelity of VE training systems. TEE-FAST evaluates at the cue level how information is presented to users and...
Article
This paper presents pilot study results on the learnability and effectiveness of the System for Tactile Reception of Advanced Patterns (STRAP) that is capable of displaying complex information through tactile actuators on the user's torso. Information requirements from dismounted soldier communications and tactile design guidelines resulted in 56 d...
Article
Full-text available
We report three experiments on manual detection of torque variations experienced through a rotary switch. The experiments were designed to investigate whether torque perception was determined by the spatial or by the temporal characteristics of the rotary switch. In Exp. I, manual detection thresholds of torque variation were measured with raised s...
Conference Paper
Automotive interior has become the next battleground for quality, customer satisfaction and emotional appeal. As an integral part of vehicle interior, operating quality of switches has a direct impact on the customer’s overall perception of quality. As of today, work in switch design and engineering has focused primarily on visual appeal, ergonomic...
Conference Paper
The "feel" of a switch depends not only on the dynamics of the switch itself, but also on the motion and dynamics of the human hand that actuates it. We have measured dynamic quantities during human actuation of a switch. We present a graphical representation technique called the "haptic profile" which emphasizes aspects of the feel of a switch as...

Full-text available
This study is part of an ongoing research program aimed at understanding how humans perceive the properties and qualities of everyday objects such as rotary switches. This article reports our measurement of detection thresholds for torque vibrations transmitted through a passively-held rotary switch. We show that the torque thresholds are very simi...

Switches are everyday objects that interface humans to many func-tionalities and influence our perception of the machinery that they are attached to. This study is aimed at a better understanding of the perceptual attributes of switches. Specifically, the perceptual thresholds for dynamic changes in a ro-tary switch were evaluated in two experiment...
