We have been discussing the following usability goals and design principles:
• Usability is broken down into these goals:
• Effectiveness – how good a product is at doing what it is supposed to do
• Efficiency – the way the product supports users in carrying out their tasks
• Safety – protecting users from dangerous conditions and undesirable situations
• Utility – provides the right kind of functionality so users can do what they need or want to do
• Learnability – easy to learn
• Memorability - easy to remember how to use
• Most common design principles:
• Visibility: are functions and features clearly visible?
• Feedback: confirming what has been done or giving information about the current state
• Constraints: ways of restricting the kinds of interactions that can take place at a given moment
• Consistency: interfaces have similar operations and similar elements for achieving similar tasks
• Affordances: attributes of an object that allow people to know how to use it
