What technique informs users about their progress while completing a form?

The technique that informs users about their progress while completing a form is inline validation. This approach provides real-time feedback as users fill out their information, allowing them to see immediately whether their inputs meet the required criteria for each field. It enhances user experience by preventing errors before submission, helping users understand which parts of the form are completed correctly or incorrectly. This immediate feedback can include visual indicators such as checkmarks or warning messages that clarify what needs to be corrected, thereby fostering a smoother and more efficient form-filling process.

In contrast, inline feedback encompasses a broader range of responses to user actions, while error notification typically focuses on alerting users after they have attempted to submit a form. Form guidance involves providing instructions or examples alongside form fields but does not specifically address the progress feedback aspect as inline validation does.
