Nielsen's Usability Heuristics, developed by Jakob Nielsen, are a foundational set of guidelines used to evaluate and enhance user interface design. These principles focus on making software interfaces more intuitive, efficient, and user-friendly. The framework is widely adopted due to its simplicity and effectiveness in identifying common usability issues, making it an essential tool in user experience (UX) design.
Visibility of system status: Keep users informed about what is going on through appropriate feedback within a reasonable time. | Match between system and the real world: Speak the users' language with words, phrases, and concepts familiar to the user. | User control and freedom: Users often perform actions by mistake. Provide a clearly marked 'emergency exit' to leave the unwanted action without having to go through an extended process. | Consistency and standards: Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform and industry conventions. | Error prevention: Design the system so that users cannot make serious errors, or at least confirm them before they commit to the action. | Recognition rather than recall: Minimize the user's memory load by making objects, actions, and options visible. | Flexibility and efficiency of use: Allow users to tailor frequent actions. | Aesthetic and minimalist design: Interfaces should not contain information which is irrelevant or rarely needed. | Help users recognize, diagnose, and recover from errors: Error messages should be expressed in plain language, precisely indicate the problem, and constructively suggest a solution. | Help and documentation: Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation.
