  • VISUAL CUES AND CONSTANCIES:
    1. Height in plane
    2. relative size
    3. occlusion
    4. linear perspective
    5. retinal disparity
    6. convergence
  • HEIGHT IN PLANE-

    This cue involves the placement of objects in a scene in relation to the horizon or the ground place.
    Objects that are higher in the visual field are perceived as farther away, while those that are lower in the visual field are perceived as closer.
  • RELATIVE SIZE-

    This cue involves using the size of familiar objects as a reference to determine their distance.
    Objects that appear smaller in the visual field are perceived as farther away, while those that appear larger are perceived as closer.
  • OCCLUSION-

    This cue involves using overlapping objects to determine their relative distance.
    When one object partially covers another, the covered object is perceived as father away than the object that is covering it.
  • LINEAR PERSPECTIVE-

    This cue involves the way parallel lines appear to converge in the distance.
    when looking down a long straight road, for example, the sides of the road appear to converge toward a point in the distance. This cue can give us an idea of the distance and depth of a scene.
  • BINOCULAR DEPTH CUES are visual cues that rely on the coordination of both eyes and enable us to perceive depth and distance in three-dimensional space.
  • There are two main BINOCULAR DEPTH CUES-
    1. Retinal disparity:
    Retinal disparity refers to the slight difference in the image received by each eye due to their slightly different perspectives. The brain combines these two slighty different images to create a single three-dimensional image.
    the greater the disparity between the images, the closer the object is perceived to be. This is why we perceive objects as being more distant when we close one eye.
  • There are two main BINOCULAR DEPTH CUES-
    2. Convergence:
    convergence refers to the inward movement of the eyes when focusing on nearby objects. The brain uses the degree of eye convergence to estimate the distance of an object. when an object is close, the eyes have to converge more, and when an object is far away, the eyes converge less.
  • visual cues and constancies allow us to accurately judge distances, sizes, and positions of objects in our environment, and play an important role in our everyday visual experiences.
