Immersive technologies, such as virtual and augmented reality, initially failed to live up expectations, but have improved greatly, with many new head-worn displays associated applications being released over the past few years. Unfortunately, ‘cybersickness’ remains a common user problem that must be overcome if mass adoption is realized. This article evaluates state of research on this problem, identifies challenges addressed, formulates an updated cybersickness development (R&D) agenda....

We present diagnostic criteria for motion sickness, visually induced sickness (VIMS), disorder (MSD), and VIMS (VIMSD) to be included in the International Classification of Vestibular Disorders. Motion are normal physiological responses that can elicited almost all people, but susceptibility severity high enough response considered a some cases. This report provides guidelines evaluating signs symptoms caused by physical or visual diagnosing an individual as having is severe constitute...

When investigators fail to find a materiel cause for mishap, pilot error may be implicated. Controlled flight into terrain (CFIT), aircraft upset (AU), and loss of control (LOC) are important mishap contributors. Spatial disorientation (SD) is key causal factor CFIT its presence can precipitate or exacerbate LOC. SD typically inferred based on unusual inputs by the pilot, insufficient outside visual cues, factors which would distract from primary instruments, qualitative similarity...

Tactile displays promise to improve the information-processing capacity of operators, especially when used in conjunction with visual and auditory displays. In this article, we describe current applications future directions tactile cuing.

Controlled flight into terrain (CFIT) and spatial disorientation (SD) constitute the first second largest categories of loss control (LOC) mishaps for helicopters. Since SD tend to result in death pilots, is inferred as primary cause a mishap via process elimination, i.e., it considered only when materiel cannot be ascertained. In mishaps, information required maintain aircraft available but they are either not attending or unable manage assimilate rapidly enough prevent mishap. For past 18...

Recent system development efforts have been made concerning a Tactile Situation Awareness System (TSAS). TSAS is garment containing vibrotactile stimulators that provide aircraft flight control feedback to the torso. intended improve human factors during by reducing workload, increasing situation awareness, and likelihood of brownout mishaps. During simulation tests, pilots using demonstrated ability non-visually hover helicopters, while consistently reporting reduced workload increased...

Motion sickness adversely affects military air and sea operations. Medications help prevent motion but are frequently associated with side effects. Better medications or combinations of needed. Dextroamphetamine has documented anti-motion effects also a potential for abuse. Modafinil is relatively new central nervous system stimulant that none the drawbacks dextroamphetamine, not been evaluated treatment sickness.This double-blind, placebo-controlled study efficacy modafinil, alone in...

Providing information via the tactile sensory system allows pilot to increase awareness without further taxing visual and auditory perceptual systems. In this study, cues were presented pilots for target orientation during a simulated helicopter extraction over moving target. The efficacy of provided by was assessed under various conditions (rested vs. fatigued, clear degraded environment).This study employed mixed-model 2(4) factorial design, including one between-subjects variable...

Abstract Introduction One challenge clinicians face is determining when a military Service Member (SM) can return to duty after an injury that affects the postural control. The gold standard measure control Sensory Organization Test (SOT). This test measures amount of sway present in individual’s static stance may be used examine range function and monitor recovery from injury. Normative values currently available were developed using sample clinically normal adults general population (i.e.,...

Software innovations at our laboratory have made novel measures of shooting performance available to researchers, even when the data comes from a fielded military firearms training simulator not designed for research. This study analyzed specific patterns rifle handling and control determine how they affected reaction time accuracy among shooters differing skill levels. The results indicated skilled employed smoother more efficient movement while aiming than less-skilled shooters. While know...

Objective: Identifying Department of Defense (DoD) occupations affected by injuries to the head and sensory systems. Methods: We explored Medical Epidemiology Database identify with highest incidence injured personnel, then ranked how frequently they occurred in a top 10 list for each four injury categories (head/brain, visual, auditory, vestibular) encompassing 25 codes. Across all categories, most were identified, among which we chose three Army combat-related military occupational...

Loss of situation awareness (SA) is a major contributor to aircraft mishaps. This paper describes technological (display) countermeasure for loss in flight and considers its key remaining transition challenges. The display tactile system (TSAS) that provides cues concerning motion. For example, if helicopter drifts upwards, forwards, or downwards away from desired hover, the pilot would feel vibrotactile pulse on top his/her shoulders, front torso, beneath buttocks, respectively. challenge...

Objective: The purpose of this paper was to provide an extensive description a case sopite syndrome, manifestation motion sickness scarcely described in the literature.Design: following questionnaires were used assess syndrome symptoms pre, during and post parabolic flight; Misery Scale rate, Positive Negative Affect Scale, Motion Sickness Assessment Questionnaire Epworth Sleepiness Scale.Study sample: Case report 35-year old female compared control group (n = 26).Results: We describe...

The Tactile Situation Awareness System (TSAS) began as a sensory cue to counteract pilot spatial disorientation. More recent adaptations of TSAS provide feedback for postural instability and cues persons with hearing loss. This demonstration included brief presentation on past developments applications. Attendees experienced an interactive the hover-drift countermeasure helicopter pilots, well applications vibrotactile looming, stability, aiding target localization in pilots noise-induced

The U.S. Army, together with NASA and the Navy, have developed flight tested a tactile cueing display that addresses several of causes aircraft upset. Tactile Situation Awareness System (TSAS) continuously presents critical parameters providing intuitive situation awareness, permitting aircrew to perform basic skills aviating non-visually more “automaticity,” whilst simultaneously attending other tasks visually. Five Army accident investigators, who were provided demonstrations TSAS...
