Design rule 3•Allowing users to be in control of thesoftware•Application of corollary 1•User should control the software instead ofsoftware controlling the user
Ways to put users in control• Making the interface forgiving• Make the interface visual• Provide immediate feedback• Avoid modes• Make the interface consistent
Making the interface forgiving• Users action must be reversible – Physical(pointing to wrong command) – Mental(wrongly deciding to select data or command)
Make the interface visual• Interface must provide list of items, instead of users to remember all choices
Provide immediate feedback• Users must receive the feedback immediately
Avoid modes• Modes force the user to focus on the ways An application works, instead of on the task they want to complete• Some of the modes – Modal dialog • Sometimes an application needs information to continue, such as name of a file into which users want to save something – Spring loaded modes • Users must take same action to remain in that mode • Ex: dragging mouse – Tool driven modes
