Chapter 9

Question 1

Biological motion

Answer 1

With very limited info, people perceive human (or animal) locomotion with 3D info

Question 2

Streaming perspective

Answer 2

Flow of visual array as you move toward a target-texture elements expand out radially toward you-film of this gives sense of motion(IMAX) “vection”

Question 3

Induced motion of the self

Answer 3

Visual/vestibular info interact

Question 4

Binocular disparity

Answer 4

Differences in images falling on right/left eye

Question 5

Stereopsis

Answer 5

Impression of 3D “popping out”

Question 6

Veith-muller cycle

Answer 6

An imaginary circle that runs through the eyeballs and the object being fixated-objects on the circle project to corresponding retina points and have 0 disparity (can be fused). Objects significantly off this circle are seen as 2(double vision)

Question 7

Steroscopes

Answer 7

Free fusion and random dot stereograms

Question 8

Binocular neurons

Answer 8

Primary visual cortex-some respond to 0 disparity, but others respond to slight disparity (disparity tuned neurons)

Question 9

Pictorial depth cues

Answer 9

Occlusion
Shading/shadow
Aerial perspective
Linear perspective
Retinal/familiar size. Relative size
Texture gradients
Height in the plane
