Book excerpt: There has been growing acceptance of the insight that the methods so far used in the testing of visual functions have been inadequate when it comes to specific problems and should, therefore, be supplemented with more specialised methods for dynamic testing. As long as two decades ago, large-scale mass screening produced evidence to the effect that visual acuity, so far exclusively determined by means of still samples, was not identical with visual acuity in the ocular pursuit of moving targets (dynamic visual acuity). In other words, vision testing can, at present, provide little informa tion on an individual's capability of identification, appreciation, and judge ment of mobile objects. Spatial, three-dimensional perception of moving targets, hereafter re ferred to as dynamic stereoacuity, is the particular subject on which findings are reported in this article. Findings of that kind are of considerable relevance to everyday life, since many of the phenomena that have to be three-dimensionally perceived in private life and in occupational practice, are in movement. So far, dynamic stereoacuity has never been systematical ly studied and is still a blank space on the maps of ophthalmology and physiology. This is equally true for dynamic stereoscopy in binocular vision as well as for perception on the basis of movement parallax, a phenomenon of differentiated contour displacement within a given field of vision which is also available to the monocular individual under conditions of head or body or object movement within the visual space.

Download or read book Perceiving in Depth Volume 2 Stereoscopic Vision written by Ian P. Howard and published by Oxford University Press. This book was released on 2012-01-27 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.

Available in PDF, EPUB and Kindle. Book excerpt: This is the second of two edited volumes from an international group of researchers and specialists, which together comprise the edited proceedings of the First International Conference on Engineering Psychology and Cognitive Ergonomics, organized by Cranfield College of Aeronautics at Stratford-upon-Avon, England in October 1996. The applications areas include aerospace and other transportation, human-computer interaction, process control and training technology. Topics addressed include: the design of control and display systems; human perception, error, reliability, information processing, and human perception, error, reliability, information processing, and awareness, skill acquisition and retention; techniques for evaluating human-machine systems and the physiological correlates of performance. While Volume one is more clearly focused on the domain of aviation and ground transportation, Volume two is concerned with human factors in job and product design, the basics of decision making and training, with relevance to all industrial domains. Part one opens with a keynote chapter by Ken Eason. It is followed by Part two dealing with learning and training, while Part three reflects the rapidly growing area of medical ergonomics. Part four entitled 'Applied Cognitive Psychology' is biased towards human capabilities, an understanding of which is central to sound human engineering decisions. Part five firmly emphasizes equipment rather than its human operators.

Available in PDF, EPUB and Kindle. Book excerpt: "This is the report of a symposium representing the research program of the Physiological Psychology Branch of the Office of Naval Research. Host for the occasion on 10-11 March 1955 was the U.S. Naval School of Aviation Medicine where many ONR contractors in the fields of physiology and aviation psychology have integrated their research with that conducted by the Navy. The physical setting for the symposium provided other ONR contractors with an opportunity to acquaint themselves with research being conducted at Pensacola, while Pensacola personnel enjoyed the stimulating exchange of information and theories which characterized the sessions. The many outstanding scientists attending represented such diverse fields as physiology, psychology, neuroanatomy, psychophysics, psychoacoustics, and biochemistry. This multiplicity of disciplines provided a rich source of stimulation as each specialist became better aware of the techniques, contributions, and problems of the other, and the relationship of his own efforts to the search for a broader knowledge of the human organism."--Foreword

Book excerpt: A revelatory account of the brain's capacity for change When neuroscientist Susan Barry was fifty years old, she experienced the sense of immersion in a three dimensional world for the first time. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she saw the city of Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a "critical period" in early childhood. According to this theory, Barry's brain had organized itself when she was a baby to avoid double vision - and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. Dubbed "Stereo Sue" by renowned neurologist Oliver Sacks, Susan Barry tells her own remarkable journey and celebrates the joyous pleasure of our senses.
