<p>A computer system for producing a navigation tool is described comprising: a display unit, an input unit, a memory unit and a digital processing unit wherein: the display unit displays, in the form of an image on a screen, a form into which categories of information may be entered using the input unit such that each category of information is grouped with the closest categories of information to provide an associated grouping and wherein each associated grouping is connected to a grouping the contents of which are mutually associated but which are different from the categories in the first grouping; a processing unit which, on completion of the form, places the categories onto points of the three dimensional structure such that the combined grouping lies on a common plane, rotates the planes to allow the user to verify the arrangement of the categories to assess whether the category at each point is related to each of its nearest neighbours; and allows the user to reposition categories within the groupings or between groupings until an acceptable navigation tool is produced.</p> |
