User
navigation is via graphical mappings
from the biosystem diagram and a menu that explains
the linkages of the interactive interface. Navigation
is possible through three methods as outlined in
the following. To demonstrate this navigation, let
us use the website.
Method
1 is "graphical-mapping". This is the
main navigation module of VISION. Contained on each
page is a central area for user navigation via graphics
and descriptive text. Images are clickable for navigating
the biomodel. If pages contain subpages, click the
yellow arrows to access them.
Method
2 is "menu-and-layer". On the upper righthand
corner of most pages is this button
. Click it to display a layer, or pop-up
window, which sits "on top" of the browser
window. A sitemap is displayed which outlines
the entire site with a collection of hyperlinks.
This layer functions as a second window for easy
access to other parts of the site without leaving
your current page. Layers can exist on top of other
layers. To exit the layer, click on the "X"
at the upper righthand corner.
Method
3 is "indexing". On the upper lefthand
corner is text separated by two carats (">>").
This indexes the user's current page in a hierarchal
manner with access to upper levels via the hyperlinks.
