Dillon, McKnight, and Richardson ([7], pp 172 - 175) explain that there are important distinctions between physical representations and semantic intentions of hypertext. It is no surprise that the Wayfinding study concludes that usable web sites must include both structural and semantic constructs.

If the content consist of material already in print, then the first design principle can be summarized by the following picture:

Figure 3: Design Principle #1 for Conversion

Direct conversion from text to hypertext doesn't work. Human beings do not read computer screens as they read print. What we've come to accept are standards for ink on a wood pulp derivative. Texture, density, reflection, economics, and size are but a few of the characteristics peculiar to print. Each is different for the computer screen and has a different effect on human tolerance. The density of a character is up to 100 times greater on the printed page and has an enormous effect on how long a person is willing to read continuously.
