Depth cues There are three main classes of depth cues: oculomotor cues, visual binocular cues, and visual monocular cues. PERCEIVING DEPTH AND SIZE 7.1 Oculomotor Cues Oculomotor cues are due to convergence and accommodation. Visual information within both eyes such as pictorial cues. The relation between perceived distance (0') and physical distance (0) of a point of light in Experiment 1 for three pivot distances (0,), using the comparison or . For each cue, discuss the kind of information it provides (e.g., depth order, relative depth, absolute depth, and in what ways the information is ambiguous), and in what depth ranges does it provide useful and accurate depth information. We predicted that infants would actively attend to specific pictorial depth cues that denote shape (e.g., T-junctions), and in the context of an impossible figure that they would fixate to a greater extent in anomalous The kinesthetic sensations of the contracting and relaxing ciliary muscles (intraocular muscles) is sent to the visual cortex where it is used for interpreting distance/depth. looking at a near object to looking at a far object?

Binocular Rivalry is a visual phenomenon characterized by oscillation between two different perceptions of a constant stimulus (Bradley, 2012). 1.0 Points. 2 Slide 3 ICS 280: Visual Perception Cue Approach Identifies information on the retina Correlates it with the depth of the scene Different cues Previous knowledge Slide 4 ICS 280: Visual Perception Depth Cues Oculomotor Monocular Binocular Question 3 of 54. Briefly describe how each of the pictorial cues provides depth information. Stereo depth cues or binocular depth cues are when the photoreceptors or movements of both eyes are required for depth perception. The way the visual system reconstructs depth information is analogous to the way the auditory system localizes sound from an intrinsically non-spatial detector. 98 CHAPTER 7. Stereo Depth Cues. patterns of oculomotor activity as infants viewed pictures of possible and impossible objects. The oculomotor depth cue that involves adjusting the shape of the lens to focus an image sharply on the retina is called. This is called convergence. 3. 10 Binocular Depth Cues Pictorial cues are two . - Change of the focal length of the lens. Depth perception also depends on binocular cues, which are only available when both eyes are used. What depth cue could be classified as a binocular cue and an oculomotor cue? It has been argued that either oculomotor or static depth cues are necessary to disambiguate the rotational and translational components of the flow field and, thus, to support accurate heading estimation. The ability to perceive depth and judge distance in the world around us, uses three visual cues: Monocular, Binocular and Oculomotor cues. When looking at nearby objects our eyes move inwards. Our ability to perceive spatial relationships in three-dimensions is known as depth perception. Looking for a Similar Assignment? They are generally regarded as. We have re-examined this issue using visually simulated motion along a curved path towards a layout of random points as the stimulus. Strabismus. 3. Using a variety of examples and demonstrations,. Accommodation is the processes by which the lens changes shape in order to bring an object in focus on the retina. 2.2 Oculomotor depth cues A xation of near targets evokes three oculomotor responses: accommodation, convergence, and pupillary con- striction, which is in combination referred to as the ocular . Depth cues Oculomotor cues consist of accommodation and vergence. Ciliary muscles are the muscles that change the focal length by compressing the lens of the eye. depends on both eyes; retinas in our eyes receive different images: .1 What does "oculomotor" refer to in the term oculomotor depth cues? Oculomotor Cues ØConvergence v Inward movement of the eyes v Required to keep image on fovea v Muscular (afferent) signal cues distance . Cues of egocentric distance 1165 Fig. This can happen through (a) one image being read by both eyes, or (b) two different things being read by either eye. Be able to describe the concepts: disparity, vergence and accommodation. Chapter 7Depth and Size Perception Monocular and Oculomotor Depth Cues Monocular Depth Cues: Pictorial Cues 1. 6 The cue approach •Begin by asking what information is available 7 Oculomotor cues: •Based on potential ability to register position of eyes in the head and muscle signals within the eye 1.Accommodation -We automatically adjust our focus for the correct distance, can we use this information for judging depth? The kinesthetic sensations of the contracting and relaxing ciliary muscles (intraocular muscles) is sent to the visual cortex where it is used for . This is an oculomotor cue for depth perception. 6.2 In the process of accommodation, how does the shape of the lens change when you switch from. Oculomotor depth cues comprise convergence and accommodation, which are de-pendent on each other and also on the binocular depth cue's disparity or stereopsis. Stereo depth cues or binocular depth cues are when the photoreceptors or movements of both eyes are required for depth perception. Our eyes move inward when we focus on nearby objects and we can use this movement to determine distance. Oculomotor depth cues. • Monocular - cues that come from one eye. An insect is most likely to use __ to perceive depth. - Rotation of the eyes towards each other for closer objects. Transcribed image text: Oculomotor cues, including binocular convergence and accommodation, help us to perceive depth. The second component is related to angular size, and the weighting accorded to it grows with viewing distance. O None of the above. Relative size 4. Depth and 2006; Vishwanath & Kowler, 2004) that the oculomotor program Within this interval the perceived depth corresponded to the in- uses mainly perceptual cues for guiding saccadic, and to a lesser duced depth. This was shown by separating their effects from the effect of the oculomotor cues by creating cue conflicts between either the familiar size cue or linear perspective, on the one hand, and accommodation and convergence, on the other. This is called convergence. Another oculomotor cue is accommodation, which refers to the variation in optical power produced by a thickening of the lens of the eye when focusing on a close object.

A dynamic depth cue—the gradual revealing ("de-occlusion") of an object as it emerges from behind another one—is called: partial occlusion and relative height. Relative height 3. and when looking at far away objects, our eyes move outward, as shown in Figure 7.1. - Quite a weak depth cue and only effective for distances < 2 m. • Convergence. Both the image size of a familiar object and linear perspective operate as distance cues in stereoscopic depth constancy. Other eye muscles help the eyes to focus to see objects. Shadows and shading Occlusion: a visual cue that occurs when one object partially hides or obstructs the view of a second object . Perceiving Depth! The impact of Visual information within a single eye. • Binocular disparity - each eye receives a slightly different view of the world. 2. Masayuki Ito, 1970, Chris Tyler, 1990 Gravity What does oculomotor refer to in the term "oculomotor depth cues"? Some eye muscles angle the eyes inward to focus. Looking for a Similar Assignment? 6.3 Why does convergence work as a depth cue only when you're looking at objects closer than about 2. m? Color constancy deals with the perception of color independent of illumination. Accommodation - feedback from changing the focus of lens.
