The goals of this research were to substantiate the existence of the cry-wolf effect for alarm responses, quantifying its effect on operator performance. A total of 138 undergraduate students performed two blocks of a cognitively demanding psychomotor primary task; at the same time, they were presented with alarms of varying reliabilities (25, 50 and 75%(More)
OBJECTIVE The aim of this study was to determine the effect of head movement frequency and predictive compensation on (a) latency produced in a monocular see-through helmet-mounted display (HMD) test bed and (b) simulator sickness experienced by users wearing the HMD. BACKGROUND There is conflicting research regarding latency as a significant factor in(More)
CHI Systems, under contract to the U. S. Army Research Institute, is developing an immersive training system, called Virtual Environment Cultural Training for Operational Readiness (VECTOR), which applies highly experiential, scenario-based virtual environments to training in cultural familiarization. To produce an interactive, realistic training(More)
The present study investigated operator performance based on sensory and cognitive task performance measures obtained during high G In both an upright seat and two reclined seats (PALE and tilt-back). Subjects were required to perform both a perceptual/motor and a classification task under varying levels of G. Data were gathered pre-G, during acceleration,(More)
OBJECTIVES We examine the time course of performance recovery from gravity-induced loss of consciousness (GLOC) and evaluate the utility of exposing participants to repeated bouts of GLOC in promoting recovery time. BACKGROUND A substantial number of accidents among fighter pilots have resulted from episodes of GLOC. U.S. Air Force doctrine holds that(More)
Prior research has examined how individuals place trust in single (e.g., Meyer, 2001, 2004) and multiple (e.g., Geels-Blair, Rice, & Schwark, 2013) automated devices when one fails. This has shown that participants are influenced by system-wide trust (SWT). What has been missing is an investigation into what types of people succumb to SWT effects. The(More)
