We seek clarity, order, and trustworthiness in information sources, whether they are traditional paper documents or Web pages. The spatial organization of graphics and text on the Web page can engage the user with graphic impact, direct the user's attention, prioritize information, and make the user's interactions with your Web site more enjoyable and more efficient.
Man is the great pattern-maker and pattern perceiver.
No matter how primitive his situation, no matter how tormented, he cannot live in a world of chaos. Graphic design creates visual logic, an optimal balance between visual sensation and graphic or text information. Without the visual impact of shape, color, and contrast pages are often graphically boring and will not motivate the viewer to investigate their contents. Dense text documents without the contrast and visual relief offered by graphics and careful page layout and typography are also more difficult to read, particularly on the relatively low-resolution screens of current personal computers. However, without the depth and complexity of text, highly graphic pages risk disappointing the user by offering a poor balance between visual sensation, text information, and interactive hypermedia links.
