Question
Experiments reveal that most humans can see objects with depth perception in a region, or
"stereoscopic field of view," determined by a 115° angle, as shown in the diagram. The diagram
shows a bird's-eye view of a person at point Plooking in the direction of an object at point O. The
arrows represent the extent of the region where the person can perceive depth.
Answer:
115°

the width of the region on the wall that the person can see with depth perception?
P
Answer:
meters
Part B: How far from the wall would a person have to stand in order to see a 20-meter-wide region
with depth perception? Give the smallest distance that achieves a region of this width.
meters
