Question

What is the purpose of providing an "emergency exit" in a system, as per Nielsen's heuristics?

a.

To undo accidental user actions

b.

To provide a shortcut for experienced users

c.

To prevent errors from occurring

d.

To enhance the aesthetics of the interface

Answer: (a).To undo accidental user actions Explanation:The heuristic "User control and freedom" emphasizes the importance of providing users with an "emergency exit" or a way to undo actions they might have taken by mistake. This helps users avoid being stuck in unwanted states without an option to backtrack or undo their actions. By offering control and freedom to the users, they can navigate the system confidently.
