Visual adaptation in central and peripheral vision
Peripheral vision occupies as much as 99.9% of the visual field beyond the fovea and serves important functions such as getting the gist of a scene and capturing important objects for central vision to be further processed. Phenomenon such as crowding, Flashed Face Distortion effect (FFDE) …

Elizabeth Bishop's Photographic Poetics: The Peripheral Vision
Elizabeth Bishop‘s poetics of description has been the object of numerous critical studies. These most often focus on questions of observation, positioning, framing, and refer to Bishop‘s aesthetics as ―optical poetics.‖ Instead of simply using optical vocabulary to talk about her work, I …

At the interface of materials and objects in peripheral vision
… interface of object and texture perception in vision, focusing on utilizing the intrinsically impaired perception in the periphery to disambiguate the predictions of different models. I find that many seemingly separate perceptual phenomena in crowding can be better understood as different …

Photographing the invisible: A practice based photographic investigation of different environments using peripheral vision as a phenomenological narrative on the consciousness of space and place
… the use of still photography to capture our peripheral interaction with the environment that we either do not notice or take for granted. The aim is to capture this invisible daily interaction with the world in photographic form as a participant rather than a spectator. Photographs that form …

Visual features for scene recognition and reorientation
… portion of scene processing must take place in peripheral vision. People are able to perform many scene perception tasks, such as determining whether a scene contains an animal, quickly and easily in peripheral vision. This is somewhat surprising because many perceptual tasks with simpler …

Perceptual learning in foveal and peripheral contrast discrimination: exploring the effects of stimuli on learning and the effects of learning on spatial vision
… learning has been shown to improve spatial vision in amblyopia but has not previously been employed to investigate crowding in amblyopia. The purpose of this work was to investigate the effect of surrounding stimuli parameters on crowding and perceptual learning (PL), and the effect of PL on …

Eye-movement control during scene viewing
… during scene viewing is the roles of central and peripheral vision, which process information differently and are therefore specialized for different tasks (object identification and peripheral target selection respectively). Yet, rather little is known about the contributions of central and …

A study in human attention to guide computational action recognition
Computer vision researchers have a lot to learn from the human visual system. We, as humans, are usually unaware of how enormously difficult it is to watch a scene and summarize its most important events in words. We only begin to appreciate this truth when we attempt to build a system that …

The molecular investigation of Stargardt disease in South Africa
… reduction of central visual acuity and normal peripheral vision. The ABCA4 (adenosine triphosphate binding cassette transporter) gene is the only gene implicated in the autosomal recessive (ar) form of the STGD phenotype, while one genetic locus and one gene have been shown to be causative of …

Functional analysis of A 5' untranslated variant in rhodopsin : implications for the retinitis pigmentosa phenotype
… Symptoms include night blindness and gradual peripheral vision loss, which progresses to a complete loss of vision. Clinical, phenotypic and genetic heterogeneity are frequently observed in RP. Mutations in Rhodopsin (RHO) have been identified as a major cause of RP. A sequence variant …

Heart Rates of Law Enforcement Officers During Deadly Force Scenarios
… rate, Beats per Minute (BPM). Motor skills, peripheral vision and depth perception are affected by an increase in the heart rate. There are advantages to knowing if experience, training, age and Body Mass Index (BMI) have an effect on the heart rate of the law enforcement officer during a …

The Spillable Environment: Expanding a Handheld Device's Screen Real Estate and Interactive Capabilities
… with a larger screen. Users can then use their peripheral vision to recognize spatial relationships between objects and solve problems more easily with this integrated system. In the spillable environment, the handheld device uses a DiamondTouch Table, a large, touch-sensitive horizontal table, …

Compatibility in the visual field and the use of nontraditional flight displays
… of the task in the visual field (central or peripheral). The attentional costs associated with time-sharing visual-spatial tasks were also addressed. The use of non-traditional flight displays to reduce visual overload in the cockpit was also explored. Three flight displays (central, …

Development of a Peripheral-Central Vision System to Detect and Characterize Airborne Threats
… sensing methods are merged to mimic human vision in support of counter-UAS applications. In the proposed sensing system architecture, a ``peripheral vision'' camera (with a fisheye lens) provides a large field-of-view while a ``central vision'' camera (with a perspective lens) provides high …

Fahrzeugführung und gleichzeitige Nutzung von Fahrerassistenz- und Fahrerinformationssystemen
… information display was simulated. The forced peripheral driving paradigm (Bhise & Rockwell, 1971; Summala, Nieminen & Punto, 1996; Lamble, Laakso & Summala, 1999) was used where the lateral position of the vehicle in the lane is only controlled through peripheral vision while fixating an …

Earlier Detection of Antiphospholipid Syndrome
… a baseball game when all of a sudden the vision in both his eyes went black. He described it as if someone pulled a “Venetian blind” over his eyes. He has a past medical history of aortic stenosis. He was taking Valsartan, Atorvastatin, B-12, Folic Acid, and Vitamin D-3 before the episode. …

Cortical Processing of Visual Parts and Wholes
… task involving the same objects presented in peripheral vision. Behavioral data were analyzed according to theories of visual crowding to yield an objective estimate of the number of parts perceived within each object. Neuroimaging results revealed increased activation for holistic objects …

Pan-Orao and historical necessity : adjusted frames and optical settlement
… the edges of multiple frames, by engaging peripheral vision, they extend the limits of normal vision. This thesis has chosen to study such images giving them the title Pan Orao. By considering them a phenomenon it invests them partially the status of a mode of expression and at same time …
