|
Binocular or retinal disparity |
Your eyes see the world from slightly different positions. The bigger the difference in the two image the closer the object. What is used in Magic Eye 3-D pictures. |
|
|
Two types of binocular cues |
Convergence and accommodation |
|
|
Convergence |
When your eyes rotate inward when an object is closer |
|
|
Accommodation |
When the lens of eyes bulge when an object is closer |
|
|
Depth perception types |
Binocular and monocular depth cues |
|
|
Perception |
The interpretation of sensory information. What we perceive is not always what is actually present |
|
|
Monocular depth cues |
Requires only one eye |
|
|
Binocular perception |
Requires two eyes |
|
|
Two types of perception |
Depth perception and Gestalt principles |
|
|
Sensory adaptation |
Neurons will fire quickly of Highly stimulated but it will not stay at that fast rate |
|
|
Habituation |
Habituation is when you get accustomed to something so that you no longer notice it. It is under conscious control. An example is noise or objects in a room |
|
|
Sensory adaptation |
When Sensory neurons are fatigued so that you no longer sense the stimuli. This is not under conscious control. And example is getting in a very hot bath tub. |
|
|
Sensation |
Messages we received from our senses due to the stimulation of various receptors |
|
|
5 external senses |
Visual. Auditory. Taste or gustatory period smell or olfactory. And touch |
|
|
Two internal senses |
Also called proprioceptive senses. Vestibular and kinesthesia |
|
|
Vestibular senses |
Tells about the position of the head in space and gives a sense of balance |
|
|
Kinesthesia |
The sense that tells you where are the parts of your body are |
|
|
Monocular depth cues |
Cues that can be found in 2D and 3D stimuli. Interposition or occlusion, relative size, linear perspective, location in picture plane, aerial or atmospheric perspective, texture gradients, motion parallax |
|
|
Interposition or occlusion |
Closer objects block the view of farther objects |
|
|
Relative size |
If you see two items that are typically the same size but one seems larger than it is closer |
|
|
Linear perspective |
Apparently parallel lines appear to converge as they approach the horizon example railroad tracks |
|
|
Location and picture plane |
Item below the Horizon further objects are higher |
|
|
Aerial or atmospheric perspective |
The farther away an object is the more air and particles you have to look through. Objects that are farther away seem less Sharp |
|
|
Texture gradient |
Farther objects tend to be packed together. |
|
|
Motion parallax |
As you move objects that are farther away appear to move more slowly than those nearby |
|
|
Just thought principles |
Receiving a form by grouping of features and objects. |
|
|
Figure versus ground |
Figure is the object we focus on and ground refers to the contrasting background |
