In this paper we present a "lightweight" visualformalism that can be used to examine the state spacecomplexity of an interface. The method can form a basisfor designing, testing and documenting the front-end'component of a typical GUI forms based interface. Thestandard is intended to be free standing and seeks toaddress issues specific to forms based GUI interfaces.The method is based on a State Transition Diagram(STD) notation that is used to model the GUI component.STDs can be used at an early stage in the design of aninterface to quantify and control surface level complexity.Further to allowing a visualisation of the complexity ofan interface, techniques used in graph theory are appliedto determine a novel measure of complexity that can thenbe used to better usability.
