The User Input category contains criteria that determine how easily a user can complete and modify form fields and other inputs within your app. Form fields and other inputs should be clearly labeled, and error messages should make it easy to understand where an error has occurred and how to correct it.
- 3.3.1 Error Identification
- 3.3.2 Labels or Instructions
- 3.3.3 Error Suggestion
- 4.1.3 Status Messages
The goal of this testing criteria is to ensure that a user can easily understand and complete any forms or workflows within your app that require user input. Clearly labeled form fields make user input more predictable and benefit users with limited vision or cognitive disabilities. Descriptive error messages help users to quickly identify and correct issues with their inputs and can alert assistive technology users such as screen reader users when a form is unable to be submitted successfully.
