How can a system show when something goes wrong?

Every time a system fails, it must show a clear sign. This sign helps a user understand what happened. A system should not give hints too often. Hints should only appear after a user makes a mistake or pauses.

The rule

Every time a system fails, it must show a clear sign.

This sign helps a user understand what happened. A system should not give hints too often. Hints should only appear after a user makes a mistake or pauses.

A system must have a clear signal for every failure. This signal can be a specific time, a tap pattern, or a wrong input. It can also be an event recorded in the system's data. These signals help a user know there is a problem.

A student is using a learning app. The app needs to check an answer. If the app cannot check the answer, it shows a spinning wheel for more than two seconds. This tells the student the app is having trouble. The app does not give a hint unless the student waits or gives a wrong answer.

How should an AI model handle error messages?

An AI model must have a plan for error messages. The plan should define different types of errors.

Why must every wrong answer choice have specific feedback?

A developer creates wrong answer choices for a question. Each wrong choice needs a matching explanation.

How should an AI model give hints when a user makes a mistake?

When a user fails a task, the AI model should offer a hint. The hint must be specific to the sub-task where the user failed.

Why should an AI model's viewer avoid hardcoded fallback content?

Hardcoded fallback content can make the AI model seem unintelligent. It can show text that does not fit the specific question.
