- Success Criterion 3.2.2 (On Input)
  - How to Meet 3.2.2 (On Input)
  - Understanding Success Criterion 3.2.2 (On Input)

## Description

Without prior instruction, unexpected change of context due to change of user interface setting can sometimes confuse users. Users must receive instruction prior to such encounter. Providing the instruction in a way in which the user may not have the opportunity to review may leave opportunity for confusion.

Failure examples:

- Not providing instruction on the Web page preceding the user interface element that causes change of context by change of setting.

- Not providing instruction at a part of the process prior to the step where they may encounter such change of context, in case of a multi-step process in which users must go through particular steps to reach the user interface element where change of setting would cause a change of context.

- Not providing mandatory instruction about the change of context in the case of intranet Web application.

## Tests

### Procedure

1. Find occurrence of change of context due to change of user interface setting

2. Find instructional material that all users must review prior encountering of the change of context.

### Expected Results

- If #1 is true and #2 is false, then this failure condition applies and content fails the Success Criterion.
