on Navigation and Interactivity
The term navigation is commonly used in multimedia to refer to the means by which the reader or user of a work interacts with and moves about within a multimedia work, whether it be text, image, 3-D or moving image based.

Both the term "navigation", and the sense in which it used, represents a narrowing of the possibilities for interactive media. The idea of navigation is primarily founded on a very traditional notion of what an artwork might be. Fundamentally, the use of this word implies work which is more or less fixed in its content, and through which the reader can "navigate" in a non-linear fashion. This allows the emergent illusion that the reader is experiencing a dynamic and interactive work.

Such work however is not interactive.

What in fact the reader is experiencing is an advanced form of channel-hopping. The author has allowed the reader to read in a non-linear fashion and to follow their interest in the work along a number of lines...although all these reading-lines are pre-defined by the author.

An interactive work is significantly different.
