Visual cues and constancies

• What are visual cues?

  Information about movement, distance, etc.
• What are constancies in visual perception?

  Seeing an object as the same from different angles
• What are binocular depth cues?

  Depth cues using two eyes
• What is retinal disparity?

  Difference between views of left and right eye
• How does retinal disparity help in depth perception?

  It provides the brain information about depth and distance
• What is convergence in visual perception?

  Eyes point closer together for nearby objects
• What does convergence indicate about distance?

  Muscles work harder for closer objects
• What are monocular depth cues?

  Depth cues using one eye
• How does height in plane affect perception?

  Higher objects appear further away
• What does relative size indicate in depth perception?

  Smaller objects appear further away
• What does occlusion signify in visual perception?

  Obscured objects are seen as closer
• How does linear perspective affect depth perception?

  Parallel lines appear closer as they recede
• What are the key types of depth cues in visual perception?

  • Binocular depth cues: two eyes
  • Retinal disparity
  • Convergence
  • Monocular depth cues: one eye
  • Height in plane
  • Relative size
  • Occlusion
  • Linear perspective
