"Interactive Graphical Documents."
ABSTRACT
An experimental system will be described for the design, development
and presentation of computer-based documents that combine pictures
and text on a high resolution colour display.  For example, such
documents can be used for maintenance and repair tasks, videotex
data bases, or compute-aided instruction.

Our documents  are directed graphs whose nodes we refer to as pages,
in analogy to the pages of a paper book.  A page encodes a set of
simultaneously displayed pictures, actions (procedures and processes),
and indexing information.  Pages may be nested arbitrarily deeply in
chapters that serve much the same organizing function as those of
conventional books.

The system is comprised of separate programs for laying out and drawing
pictures, for graphically specifying and interconnecting pages and
chapters, and for displaying documents for user interaction.

Examples will be given from prototype maintenance and repair manuals.

Coffee and refreshments will be served at 3:00 PM.
