The Topics which are covered in this lecture are

Spatial perception

Depth Perception

Factors of depth and distance perception


Instrument used depth perception

Spatial Perception

•It includes perception of depth and perception of distance.

•Depth perception is ability to see objects in three dimensional though the images formed on our ratina – 2D.

•It allows to judge distance

•Gibson and Richard Walk 1971 declared that depth perception is as innate (inborn, Instinctive).

•They conducted an experiment with human new infant baby. 

Depth Perception

Factors of depth and distance perception

Binocular cues:  In this we saw with both eyes. Both eyes are open and we saw the image using overlapping area of vision.

•Single eyes see the object in non-overlapping filed. But we saw the image in overlapping filed. 

Monocular cues:  In this cues are received by one eye. Following are monocular cues.

Relative Size – according to law of visual angle, the image move farther away its image becomes smaller. As the object is in the same size. –For Example Aeroplan size looks small when its far away.


Relative size: object movers father away, its images on retina becomes smaller. Farther objects have smaller images and nearer images have bigger images.

Linear parallax : The clear convergence(meeting) of parallel lines are intercepted as a clue to distance that is called perspective. For example the side lines of road seems to converge inward due to distance.

Overlapping or intersection of objects : If one things covers another, then the covered thing seems farther and coverer seems nearer.

Clearness of Details : Things are more clear when they are nearer and its clearness decreases as they get farther.

Change in color : Color of object looks changes with the distance between the eye and the object. Its due to wave length of light on the object and its reflection.

–Relative height : taller things are nearer and farther things are less taller

–Relative brightness : the things nearer are more brighter than the things farther.

Instrument used depth perception

Stereoscope :  is used for depth perception. The two pictures are shown separately in each eye in a way that picture of left eye does not effect the left and the picture of right eye does not effect left.

Thus no convergence occur

Mirror telescope :

Prism telescope :

Tele stereoscope :
