Comm 1300 1-29-09 Lecture 4 Exercise 1 due Feb. 5 I. How visuals differ from reality a. Visuals are very different than real objects: i. They are flat b. How do we determine depth i. Bioncular disparity – difference in image on left vs. right eye 1. We can see slightly different sides of a ball, right eye can see right side, and left side sees left side, brain puts it together and determines depth ii. Motion parallax – change in relationship between objectives as we move 1. Motion of nearby objects seem to move fast, far objects move slowly a. In a picture, everything moves at the same speed because there is no depth iii. Texture gradients – apparent changes in density of patterns or textures 1. Far away carpet looks the same, but if it is near you, you can see the fine texture and detail iv. Occlusion – one object blocking another c. To what extent do visuals use the above ideas i. Binocular disparity (only in special types of visuals)

Unformatted text preview: 1. Magic eye: 3-D with special glasses a. Brain does not usually use binocular disparity ii. Motion parallax 1. Motion only, not in still images iii. Texture gradients 1. Still and motion a. Ex. a picture of a road, the middle yellow lines are initially far apart, but farther and father away, the yellow lines merge iv. Occlusion 1. Still and motion a. The easiest and most common way people see depth II. How documents engage a. In order to help readers recognize the documents that deserve their consideration designers must do: i. They must visibly structure the document so that the main ideas catch the attention of busy readers ii. They must use language, both visual and verable, that connects with the readers’ knowledge, experience, beliefs, and values b. think about the sender of the visual, what is their purpose?...
