• The Seeheim model separates a user interface into Presentation Layer, Dialogue Control Layer and Application Interface.
• The Abstract User Interface (AUI) model presented here differs in that it abstracts elements from each one of these components.
• The AUI specification is not limited to describing a single Seeheim component, and can be used to describe the relation between presentation, dialogue and application interface.
• That is, the AUI specification defines the abstract interaction between input, output and computation.
