CritiGUI - Knowledge-Based Support for the User Interface Design Process in Smalltalk

The Objectworks/Smalltalk programming environment offers a variety of interaction objects which allows programmers to design user interfaces for application. Programmers often lack the knowledge required to design good user interfaces. Beside the problem of consistency there are a lot of low level sources of errors, such as the size of buttons, the background and foreground colors, etc. User interfaces can be improved by providing this knowledge about design guidelines at this low level, thus giving programmers the opportunity to learn about the design of user interfaces CritiGUI is a knowledge-based critiquing system which supports programmers during the design process by providing this knowledge. It is an adaptable, after-task critiquing system which follows the analytical critiquing strategy.
