Once a design model is created, it is implemented as a prototype, examined by users (who fit the user model described earlier) and modified based on their comments. To accommodate this iterative design approach, a broad class of interface design and prototyping tools has evolved. Called user-interface toolkits or user-interface development systems (UIDS), these tools provide components or objects that facilitate creation of windows, menus, device interaction, error messages, commands, and many other elements of an interactive environment.
Using prepackaged software components to create a user interface, a UIDS provides built-in mechanisms for
managing input devices (such as a mouse or keyboard)
validating user input
handling errors and displaying error messages
providing feedback (e.g., automatic input echo)
providing help and prompts
handling windows and fields, scrolling within windows
establishing connections between application software and the interface
insulating the application from interface management functions
allowing the user to customize the interface
These functions can be implemented using either a language-based or graphical approach.
