Medical Aspects of Monocular Vision • Congenital • Industrial • Accidental • Medical Malpractice Note:Eye injuries in the workplace are very common. More than 2,000 people injure their eyes at work each day. About 1 in 10 injuries require one or more missed workdays to recover from. Of the total amount of work-related injuries, 10-20 % will cause temporary or permanent vision loss. https://www.preventblindness.org/eye-safety- work Functional Aspects of Monocular Vision • depth perception • decrease in peripheral visual field • decrease in the horizontal visual field • monocular saccades, pursuits, and near- to-far accommodation • Eye-hand-coordination • Mobility • visual system balance, coordination, and motility Vision Assessment • Complete and review results of comprehensive eye examination (within 1 year), Spectacle prescriptions as needed for improving distance and near vision, and Polycarbonate lenses Depth perception • The ability to judge depth or the relative distance of objects in space and to orient one’s position in relation to them; Also called stereopsis. Peripheral Vision Field • indirect vision, is vision as it occurs outside the point of fixation, i.e. away from the center of gaze. The vast majority of the area in the visual field is included in the notion of peripheral vision. "Far peripheral" vision refers to the area at the edges of the visual field, "mid-peripheral" vision refers to medium eccentricities, and "near-peripheral", sometimes referred to as "para-central" vision, exists adjacent to the center of gaze Horizontal Vision Field • normal vision, the horizontal visual field is about 210 to 230 degrees • monocular visual field extends to approximately 60 degrees nasally (toward the nose, or inward) from the vertical meridian in each eye, to 107 degrees temporally (away from the nose, or outwards) from the vertical meridian, and approximately 70 degrees above and 80 below the horizontal meridian. Monocular saccades, pursuits, and near-to-far accommodation. • Effect of visual distractors on saccade latency and accuracy • Visual tracking (pursuits) is an oculomotor skill that is essential for learning, reading, and so many tasks we perform • How fast and how efficiently you can focus on objects, both near and far, with your eyes Eye Hand Coordination • The ability of the vision system to coordinate the information received through the eyes to control, guide, and direct the hands in the accomplishment of a given task, such as handwriting or catching a ball Mobility Visual system balance, coordination, and motility Monocular Vision in the World of Work VISION: • NE - Near Acuity - Frequent • FA - Far Acuity - Not Present • DE - Depth Perception – Occasional • AC - Accommodation - Occasional • CV - Color Vision - Not Present • FV - Field of Vision - Not Present Handouts • Assessment Questions • Driving Tips • Instructions for 3D picture • Light and Glare • Physical Requirements-V Hands on Experience • Monocular Vision – What do you or don’t you see? 3D Picture C Cover your dominant eye and look closely at the picture.

  • Relative Importance of Binocular Disparity and Motion Parallax for Depth Estimation: a Computer Vision Approach
    remote sensing Article Relative Importance of Binocular Disparity and Motion Parallax for Depth Estimation: A Computer Vision Approach Mostafa Mansour 1,2 , Pavel Davidson 1,* , Oleg Stepanov 2 and Robert Piché 1 1 Faculty of Information Technology and Communication Sciences, Tampere University, 33720 Tampere, Finland 2 Department of Information and Navigation Systems, ITMO University, 197101 St. Petersburg, Russia * Correspondence: pavel.davidson@tuni.fi Received: 4 July 2019; Accepted: 20 August 2019; Published: 23 August 2019 Abstract: Binocular disparity and motion parallax are the most important cues for depth estimation in human and computer vision. Here, we present an experimental study to evaluate the accuracy of these two cues in depth estimation to stationary objects in a static environment. Depth estimation via binocular disparity is most commonly implemented using stereo vision, which uses images from two or more cameras to triangulate and estimate distances. We use a commercial stereo camera mounted on a wheeled robot to create a depth map of the environment. The sequence of images obtained by one of these two cameras as well as the camera motion parameters serve as the input to our motion parallax-based depth estimation algorithm. The measured camera motion parameters include translational and angular velocities. Reference distance to the tracked features is provided by a LiDAR. Overall, our results show that at short distances stereo vision is more accurate, but at large distances the combination of parallax and camera motion provide better depth estimation. Therefore, by combining the two cues, one obtains depth estimation with greater range than is possible using either cue individually.

    6 Space Perception and Binocular Vision Chapter 6 Space Perception and Binocular Vision Monocular Cues to Three-Dimensional Space Binocular Vision and Stereopsis Combining Depth Cues Development of Binocular Vision and Stereopsis Introduction Realism: The external world exists. Positivists: The world depends on the evidence of the senses; it could be a hallucination! • This is an interesting philosophical position, but for the purposes of this course, let’s just assume the world exists. Introduction Euclidian geometry: Parallel lines remain parallel as they are extended in space. • Objects maintain the same size and shape as they move around in space. • Internal angles of a triangle always add up to 180 degrees, etc. Introduction Notice that images projected onto the retina are non-Euclidean! • Therefore, our brains work with non- Euclidean geometry all the time, even though we are not aware of it. Figure 6.1 The Euclidean geometry of the three-dimensional world turns into something quite different on the curved, two-dimensional retina Introduction Probability summation: The increased probability of detecting a stimulus from having two or more samples. • One of the advantages of having two eyes that face forward. Introduction Binocular summation: The combination (or “summation”) of signals from each eye in ways that make performance on many tasks better with both eyes than with either eye alone. The two retinal images of a three- dimensional world are not the same!

  • Clinical Suppression and Amblyopia
    Investigative Ophthalmology & Visual Science, Vol. 29, No. 3, March 1988 Copyright © Association for Research in Vision and Ophthalmology Clinical Suppression and Amblyopia Karen Holopigian,*^: Randolph Blake,* and Mark J. Greenwaldf In individuals with abnormal binocular vision, such as strabismics and anisometropes, it is common for all or part of one eye's view to be suppressed so binocular confusion and diplopia are eliminated. We examined the relation between the depth of suppression (the amount by which the monocular contrast increment threshold for an eye was elevated by stimulation in the contralateral eye) and the degree of amblyopia (difference in monocular contrast thresholds for the two eyes). There was a significant negative correlation between suppression and amblyopia, so that clinical suppressors with no ambly- opia exhibited deep suppression (ie, large threshold elevation) while observers with amblyopia exhib- ited weaker or no suppression. This negative correlation was found when the two eyes viewed ortho- gonally oriented contours as well as identically oriented contours. These results suggest that when an eye is amblyopic there is no longer a need for strong suppression of that eye by the contralateral eye.

  • Understanding Eye Movements and Attentional Mechanisms Is Key to Improving Amblyopia Treatment
    Bridging the Gap: Understanding Eye Movements and Attentional Mechanisms is Key to Improving Amblyopia Treatment By Christina Grace Gambacorta A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Vision Science in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Dennis Levi, Chair Senior Scientist Suzanne McKee Professor Stanley Klein Professor Richard Ivry Summer 2017 Abstract Bridging the Gap: Understanding Eye Movements and Attentional Mechanisms is Key to Improving Amblyopia Treatment by Christina Grace Gambacorta Doctor of Philosophy in Vision Science University of California, Berkeley Professor Dennis Levi, Chair Amblyopia is a developmental visual disorder resulting in sensory, motor and attentional deficits, including delays in both saccadic and manual reaction time. It is unclear whether this delay is due to differences in sensory processing of the stimulus, or the processes required to dis-engage/shift/re-engage attention when moving the eye from fixation to a saccadic target. In the first experiment we compare asymptotic saccadic and manual reaction times between the two eyes, using equivalent stimulus strength to account for differences in sensory processing. In a follow-up study, we modulate RT by removing the fixation dot, which is thought to release spatial attention at the fovea, and reduces reaction time in normal observers. Finally, we discuss the implications for these findings on future amblyopic treatment, specifically dichoptic video game playing. Playing videogames may help engage the attentional network, leading to greater improvements than traditional treatment of patching the non- amblyopic eye. Further, when treatment involves both eyes, fixation stability may be improved during the therapeutic intervention, yielding a better outcome than just playing a video game with a patch over the non-amblyopic eye.

  • Whale of a View
    Whale of a View Overview: To view your surroundings from the perspective of a whale and understand the difficulty of finding things around you. Ocean Literacy Principles: 5. The ocean supports a great diversity of life and ecosystems 7. The ocean is largely unexplored Key Concepts: • Whales have monocular vision, meaning their eyes are on either side of their head. • Monocular vision allows both eyes to be used separately, which increases the field of view, but limits depth perception. Materials: • Scissors • Tape • Paper towel tube per student • 2 small mirrors that fit in paper towel tube (can be found at a craft store) Duration: 30 minutes Physical Activity: Moderate 1 www.sailorsforthesea.org Whale of a View (cont.) Background: Your eyes are in front of your head. So you see what is in front of you and some of what is on either side. With both your eyes you see one view. This is called binocular vision. But whales’ eyes are on the sides of their heads. Each eye sees a separate view. This type of vision is called monocular vision. In this experiment, you’ll find out what it’s like to have monocular vision. Activity: Follow along with the pictures: 1. Have an adult cut the paper towel tube into four equal pieces. 2. Have the adult cut one end of each piece at a 45-degree angle. 3. Tape the angled ends together as shown. Repeat with the other two pieces. 4. Have the adult insert the mirror into a tube at a 45-degree angle, as shown.

    3-D Depth Reconstruction from a Single Still Image Ashutosh Saxena, Sung H. Chung, Andrew Y. Ng Computer Science Department Stanford University, Stanford, CA 94305 {asaxena,codedeft,ang}@cs.stanford.edu Abstract We consider the task of 3-d depth estimation from a single still image. We take a supervised learning approach to this problem, in which we begin by collecting a training set of monocu- lar images (of unstructured indoor and outdoor environments which include forests, sidewalks, trees, buildings, etc.) and their corresponding ground-truth depthmaps. Then, we apply su- pervised learning to predict the value of the depthmap as a function of the image. Depth estimation is a challenging problem, since lo- cal features alone are insufficient to estimate depth at a point, and one needs to consider the global context of the image.

THE EFFECTS OF OCULAR DOMINANCE ON VISUAL PROCESSING IN COLLEGE STUDENTS William Alexander Holland ABSTRACT The role of ocular dominance in processing visual memory and analytic tasks is unknown. Research has variably showed both significant effects and no effect of ocular dominance on visual perception, motor control, and sports performance. The goal of this study was to determine if there is a relationship between ocular dominance and visual processing under a variety of computer gaming tasks. This was accomplished by first determining subjects’ ocular dominance through the Miles test, and then examining the subjects’ visual performance on four different Lumosity games under three conditions: left eye, right eye, and both eyes. Results suggest a relationship between ocular dominance and score in the simplest game used, named Raindrops, but did not identify a relationship between ocular dominance and accuracy.
