Visual cues that help us perceive depth and distance using only one eye
Visual Cues
Features of the environment that give us information about movement, distance, etc.
Visual Constancies
Seeing objects as the same despite seeing them from different angles and distances
Height in Plane (MDC)
Objects that are higher up in the visual field appear further away, those that are lower are perceived as closer
Relative Size (MDC)
Smaller objects in the visual field are perceived as further away, those that are perceivd as larger are perceived as closer
Occlusion (MDC)
Objects that are in front of others are perceived as closer to us whilst objects partially covered by other objects are perceived as further away
Linear Perspective (MDC)
When parallel lines converge in the distance, the point at which they come together is perceived to be further away
Binocular Depth Cues
Visual cues that rely on the coordination of botheyes and enable us to see depth and distance in threedimensional space
Retinal Disparity (BDC)
Each eye sees things differently as they are positioned on the face about 6 cm apart. Retinal disparity is the difference in the image received by the left and right eye which the brain receives to give information about depth and distance.
The greater the disparity between the images, the closer the object is perceived to be
Converganve (BCD)
The eyes become closer together (converge) when objects are close to us. Muscles round our eyes work harder when objects are close. This information is sent to the brain to give information about depth and distance.
