Steve Krugs' recent book "Don't Make Me Think" has become a 'must have' for anyone seeking to develop their first web project or looking to make improvements to their existing site. Krug is very effective in breaking down the components of usability and interface design in to succinct packets of information. The page layout of the text of the book “Don’t Make Me Think” reinforces the overall concept that people don’t read. Important items are presented in bold bullet point with small “packets’ of information” provided to draw the reader’s attention. This technique is a representation of visual hierarchy and is used in all from of visual communication – from a printed book to a web page both exist to convey a message to the viewer, and can be used by interface designers to increase the usability of their site. Visual hierarchy provides subtle clues on how the reader’s eye should move through the organization of presented information. Farraday describes five important variables to consider when organizing a design: Size, scanning, images, text style and positioning (Farraday, 2000). His study revealed that “if the size of the text ad image are roughly equal, then text will be preferred” (p.1). While these finding may be true in a general sense, they do not reveal the impact of color and density of the user preference. References |
