Usability has following categories:, The life cycle of interactive systems, Iterative design and prototyping
•Iterative design overcomes inherent problems of incomplete requirements, Throw Away/Rapid Prototyping
•The prototype is built and tested.
• It is likely to inform the final solution, but the prototype itself will not become part of the final solution. and Techniques of Prototyping
**–is a graphical depiction of the interface without accompanying system functionality.
–can be animated, If not animated, storyboards usually include annotations and scripts indicating
how the interaction will occur.
•Limited functionality simulation:
–some part of system functionality provided by designers
