User interface design, Software Engineering

Assignment Help:

Develop a detailed design to support the use case specified in the accompanying document: ‘ Asg2 . (Hint: Follow the process for use case realization and develop analysis class Use Case Specification' and sequence diagram describing the use case before adding the details of UI interactions.) 

a. List as many requirements for the user interface as you can, without assuming anything about the implementation technology.

b. Design a graphical user interface to support the use case, using a standard set of graphical ‘widgets' such as those supported in .NET or Java Swing. Present this as either a screen shot of a GUI prototype, or a ‘storyboard' or ‘wireframe' diagram illustrating the interface. Ensure that you take account of Norman's principles in your design, and accompany your design with a brief explanation as to how your design reflects these principles.

c. Draw a state diagram modelling the behaviour of the high level class representing the user interface. In an accompanying table, identify what GUI elements are active, and what actions are possible in each state.

d. Draw a sequence diagram illustrating how the control class for the use case interacts with the UI and entity classes to support for the use case for the normal flow. Make sure this diagram is consistent with the state diagram developed for part c.
