Available in PDF, EPUB and Kindle. Book excerpt: This review concerns the problem of spatial disorientation or confusion in relation to motions encountered during flight and how those motions, or the lack of perception of motion, affect a pilots sense of true position in the air. The problem is an important one with the hope that physical training systems and supplemental forms of information will help avoid the loss of life and equipment due to disorientation.

Book excerpt: This publication was written to address the lack of information that exists today regarding spatial disorientation and its effects as it relates to divers. Spatial disorientation contributes more to causing accidents than any other psychological problem in a multi-directional space, such as diving underwater or flying through the air. Regardless of their amount of time or experience underwater, all divers are subject to disorientation. The human body is structured to perceive changes in movement when standing vertically on land in relation to the surface of the earth. When diving, the human sensory systems-the visual system, vestibular system, and proprioceptive system-can and will give the brain erroneous orientation information due to positioning and movement of the body in a space and along an axis foreign to our biological design. This information can and will cause some degree of sensory illusions, which in-turn lead to spatial disorientation, that further leads to confusion, lost time in actions, potentially harmful or dangerous reactions, and a developing spiral of out-of-control events leading to an accident or death.

Available in PDF, EPUB and Kindle. Book excerpt: Spatial disorientation is of key relevance to our globalized world, eliciting complex questions about our relationship with technology and the last remaining vestiges of our animal nature. Viewed more broadly, disorientation is a profoundly geographical theme that concerns our relationship with space, places, the body, emotions, and time, as well as being a powerful and frequently recurring metaphor in art, philosophy, and literature. Using multiple perspectives, lenses, methodological tools, and scales, Geographies of Disorientation addresses questions such as: How do we orient ourselves? What are the cognitive and cultural instruments that we use to move through space? Why do we get lost? Two main threads run through the book: getting lost as a practice, explored within a post-phenomenological framework in relation to direct and indirect observation, wayfinding performances, and the various methods and tools used to find our position in space; and disorientation as a metaphor for the contemporary era, used in a broad range of contexts to express the difficulty of finding points of reference in the world we live in. Drawing on a wide range of literature, Geographies of Disorientation is a highly original and intruiging read which will be of interest to scholars of human geography, philosophy, sociology, anthropology, cognitive science, information technology, and the communication sciences.
Download or read book An Overview of Spatial Disorientation as a Factor in Aviation Accidents and Incidents written by David G. Newman and published by . This book was released on 2007 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Flying an aircraft is a challenging activity that exposes pilots to many potential hazards. One of the most significant of these is spatial disorientation. Spatial disorientation is a condition where the pilot is unable to correctly interpret aircraft attitude, altitude or airspeed in relation to the Earth. The resulting disorientation can lead to a loss of control of the aircraft. [...] The ATSB report explains that the chances of a spatial disorientation event occurring in flight can be reduced by a series of simple preventive measures, many of which can be attended to before flight. These include flying when fit and well to do so, not flying under the influence of alcohol or medications, avoiding visual flight rules into instrument meteorological conditions, increasing awareness of spatial disorientation illusions and planning for their possible appearance at different stages of flight in the pre-flight planning process."--Publisher's website.

Book excerpt: "It has been known for many years that aircrew suffer from false sensations and perception of aircraft motion and these illusions may hazard the safety of the aircraft and its occupants. Yet, despite the many papers in the technical literature which deal with differing aspects of the problem of spatial disorientation there are few which are comprehensive and none provide the non-specialist reader with an explanation of the causes of the sensory illusions which reflect contemporary biological and medical knowledge. The text which follows was prepared in an attempt to redress this deficiency."--Preface.

Download or read book Emergent Techniques for Assessment of Visual Performance written by National Research Council and published by National Academies Press. This book was released on 1985-01-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.
Download or read book Why People Get Lost written by Paul A. Dudchenko and published by . This book was released on 2010 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: At some point in our lives, most of us have been lost. How does this happen? What are the limits of our ability to find our way? Do we have an innate sense of direction? 'How people get lost' reviews the psychology and neuroscience of navigation. It starts with a history of studies looking at how organisms solve mazes. It then reviews contemporary studies of spatial cognition, and the wayfinding abilities of adults and children. It then considers how specific parts of the brain provide a cognitive map and a neural compass. This book also considers the neurology of spatial disorientation, and the tendency of patients with Alzheimer's disease to lose their way. Within the book, the author considers that, perhaps we get lost simply because our brain's compass becomes misoriented. This book is written for anyone with an interest in navigation and the brain. It assumes no specialised knowledge of neuroscience, but covers recent advances in our understanding of how the brain represents space.
Download or read book Investigating Mitigation Strategies for Spatial Disorientation written by Amanda Joy-Hafich Bond and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial disorientation is the singular most common factor in human-error aviation accidents, and over ninety percent of those accidents are fatal. Despite advances in aviation over the past one hundred years in both technology and training, spatial disorientation mishaps continue at a steady pace, even though other incidents declining in frequency. Because spatial disorientation is a highly complex phenomena that involves the vestibular system, the visual system, and cognitive factors such as workload and attention, predicting spatial disorientation is extremely difficult. Likewise, exactly replicating spatial disorientation for training purposes is challenging as well as extremely dangerous and costly. The goal of this study was twofold: to understand if innate abilities can predict propensity for spatial disorientation, and to investigate the efficacy of using story-based vignettes -- narratives -- to train spatial disorientation to increase schematic learning in pilots. Results demonstrated that performance on a spatial orientation task such as the Direction Orientation Task (DOT) is not a reliable predictor for spatial disorientation recognition based on self-report spatial disorientation frequency. In addition, though story-based vignettes demonstrated potential for increased cue recognition over a control training event, significant differences were not found in novel spatial disorientation recognition, critical cue identification, or confidence. These findings indicate that spatial disorientation could be a completely perceptual (bottom-up) task rather than one that is both top-down and bottom-up and implies future research into the ways we describe and measure spatial disorientation in order to understand it as well as train for it.
Download or read book Disorientation written by Felicity Dale Elliston Scott and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viennese émigré architect Bernard Rudofsky (1905-1988) is most frequently recalled for curating "Architecture without Architects," the famous 1964 photography exhibition of vernacular, preindustrial structures at the Museum of Modern Art in New York. Far from simply a romantic or nostalgic invocation of cultures lost to industrial modernity, Rudofsky's exhibition drew on decades of speculations about modern architecture and urbanism, particularly their semantic, technological, institutional, commercial, and geopolitical influences. Focusing on Rudofsky's encounters with Japan in the 1950s--he described postwar Japan as a "rear-view mirror" of the American way of life--architectural historian Felicity D. Scott revisits the architect's readings of the vernacular both in the United States and Japan, which resonate with his attempts to imagine architecture and cities that refused to communicate in a normative sense. In a contemporary world saturated with visual information, Rudofsky's unconventional musings take on a heightened resonance.

Download or read book Spatial Disorientation A Survey of U S Army Rotary Wing Aircrew written by and published by . This book was released on 1996 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of 299 aircrew in current flying' practice was performed at five U.S. Army airfields within CONUS. Respondents were asked a number of questions about their worst ever episode of spatial disorientation (SD) and their worst episode in the 4 months prior to the survey. They also were asked to classify episodes as minor, significant, or severe according to the threat to flight safety. Opinions also were sought on various aircraft types and flight conditions. In the final part of the questionnaire, they were asked about their experience of break-off and giant hand phenomena. Analysis of the data showed that 78 percent had suffered SD during their flying career (8 percent had suffered severely enough to put flight safety at risk). Twenty-two percent had suffered in the 4 months prior to completing the questionnaire (2 percent severely enough to put flight safety at risk). In 33 percent of worst ever episodes, the event had affected conduct of the mission while flying accuracy had been affected in 64 percent. (The figures for the 4-month data were 35 percent and 68 percent.) Brownout, whiteout, and inadvertent entry to instrument meteorological conditions (IMC) were the most easily identifiable source of severe episodes of SD, but they accounted for 13 percent of the worst ever episodes. The leans accounted for 44 percent of episodes. Few other episodes could be linked to well known problems. Aircrew were not initially aware of being disoriented in 43 percent of worst ever episodes (38 percent of episodes when they were looking out of the aircraft cockpit). Experience had no apparent protective effect against either the incidence or severity of episodes.
Download or read book Spatial Disorientation Causes Consequences and Countermeasures for the USAF written by Todd E. Heinle and published by . This book was released on 2003 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial disorientation (SD) remains a serious drain on USAF resources and personnel. During the ten-year period of 1990-1999, the USAF experienced 36 SD-related Class A mishaps costing a total of $557M and the loss of 44 aircrew. SD is the single most common cause of human-related aircraft accidents. The causes of SD are complex and require an understanding of the types of SD, the physiology and psychology of flight, and the way pilots train for the prevention of SD. Research has shown there are three distinct types of SD unrecognized, recognized and incapacitating. Each type impacts the pilot in a different way, and each should be thoroughly understood by the pilot before he or she experiences them in flight. Results from a study of the Post-Roll Illusion (Type I), the Graveyard Spin Illusion (Type II), and a report from a pilot who experienced the Giant Hand Illusion (Type III) is presented. Spatial orientation training techniques are included. Finally, the USAF's Spatial Disorientation Countermeasures Program, designed to reduce the number of SD mishaps, is also presented. This program emphasizes shared knowledge across all flying communities, including research in the areas of attitude awareness (visual and vestibular), multi-sensory integration (3-D audio and tactile stimulation), and both ground-based training and flight- based demonstrations. Although the phenomenon of spatial disorientation (SD) has been described and documented by many, both researcher and aircrew, since the earliest days of aviation, a complete understanding of the complex mechanisms and interactions has remained elusive. The economic consequences alone of SD are enormous, both in cost of lost aircraft and cost of training new aircrew. This paper will provide examples of different types of SD, the interrelationship of SD to loss of situational awareness (LSA), and a brief summary of the US Air Force Research Laboratory's current SD Countermeasures program.

Book excerpt: I am honored to have been invited to give the keynote address to this symposium on spatial disorientation. Spatial disorientation (S.D.) is not a new problem in aviation and over the last 50 years it has been addressed on numerous occasions within the NATO community. Yet despite the increased understanding of the varied aetiology of S.D. and improvement in the display of information to the pilot to facilitate correct spatial orientation (5.0.), accidents, primarily attributable to S.D., continue to occur. Indeed, in the last decade the proportion of human error accidents in which S.D. was considered to be a primary or contributory cause of the mishaps has increased. This would appear to be due, at least in part, to the introduction of new technology, in particular night vision goggles, that has allowed flight operations in environmental conditions which previously were not possible. In the presentations to follow there will be descriptions of new technologies and training techniques that should aid the maintenance of spatial orientation (8.0.) in flight and reduce the frequency of S.D. incidents and orientation error accidents. But these benefits are likely to be tempered by new challenges arising from flight in high performance agile aircraft and unattended aerial vehicles - UAVs. The human factors and aeromedical community also need to be cognizant of S.D. in virtual reality environments as well as in those piloting UAVs.
