Exam 6: Perceiving Depth

In real-world situations, integrating depth cues provide us with:

In the context of binocular disparity, a point on the left retina and a point on the right retina are _____ points if they would coincide if the two retinas were superimposed.

Martha gazes out the window of a moving train. Billboards, telephone poles, and other objects near the railway track move past Martha very quickly, while objects in the distance move slowly. This illustrates the depth cue of:

Perhaps the most widely accepted explanation of the moon illusion is that, like most other size illusions, it results from a misperception of distance. The actual distance from an observer on the earth's surface to the moon is virtually:

According to the relative height depth cue:

The depth cue based on the slightly different retinal images in our two eyes is called:

Researchers have examined what happens when they manipulate the number of depth cues available and the degree to which those cues conflict. Such experiments have revealed a few basic principles. Identify a basic principle of depth cues.

My friend has a picture on the beach where she appears to hold the setting sun in her hands like a ball. This illusion is called the:

Research findings of random dot stereograms have shown that:

_____ is an imaginary surface defined by the locations in a scene from which objects would project retinal images at corresponding points.

In the context of the moon illusion, how does the size-distance relation affect our perception of the moon?

An anaglyph:

When we look straight at a rectangular picture frame hanging on a wall, it appears as a rectangle. If we walk off the side and look at the frame from an angle, we still recognize that it is in the shape of a rectangle. Explain the phenomenon that makes the picture frame look rectangular in shape, even when it is viewed from an angle.

Take a mug and begin to slowly move it toward the tip of your nose. While looking at the mug, continue the movement until the mug actually touches the tip of your nose and your eyes are turned in toward your nose. You begin to feel the tension in the muscles that move your eyes. Explain the depth cue that causes this phenomenon.

John leans against a wall and watches a squirrel approach a tree. As the squirrel crosses behind the tree, its body gradually disappears. This illustrates the process of:

Optic flow is a critical cue to depth when a person is driving, though it also operates, of course, when a person moves slowly through a scene. The objects and surfaces near the point toward which the person is heading is called _____, which move(s) outward slowly in the retinal image.

A dynamic depth cue-the gradual revealing ("de-occlusion") of an object as it emerges from behind another one-is called:

The text describes the next generation of 3-D video based on a technology known as holography. What obstacles would a maker of animated films have to overcome to adopt this technology?

In the context of binocular disparity, the horopter is an imaginary surface defined by the locations in the scene from which objects would:

The next generation of 3-D video will be based on _____ technology, where a viewer will be able to get different views of the scene by moving her head or walking around the display. This will involve dynamic depth cues that result from the viewer's own motion, not just from the motion of objects in the scene.
