Donald Norman's model of interaction is a theory that describes how users interact with a product or service. It consists of seven stages: Forming the Goal, Forming the Intention, Specifying an Action, Executing the Action, Perceiving the System State, Interpreting the System State, and Evaluating the Outcome.

1. Forming the Goal: This is the initial stage where the user identifies what they want to achieve. For example, a user might decide they want to send an email.

2. Forming the Intention: In this stage, the user decides on a course of action that will allow them to achieve their goal. For example, the user might decide to open their email application to send an email.

3. Specifying an Action: Here, the user determines the specific actions that need to be taken to execute their intention. For example, the user might decide to click on the "compose" button to start writing an email.

4. Executing the Action: This is the stage where the user carries out the action they have specified. For example, the user would click on the "compose" button.

5. Perceiving the System State: After executing the action, the user perceives the new state of the system. For example, the user would see the email composition window open.

6. Interpreting the System State: The user interprets the new system state to understand what has happened. For example, the user would understand that the email composition window has opened because they clicked on the "compose" button.

7. Evaluating the Outcome: Finally, the user evaluates the outcome to see if it matches their goal. For example, the user would confirm that they can now write and send an email, which was their original goal.

This model is useful for understanding the user's thought process and can help in designing more intuitive and user-friendly products and services.
