Donald Norman's Model of Interaction (Example Application)

Name of Application/System: Alarm Clock

Task to Complete: Wake up at 5:00 AM

1. What do I want to accomplish?
   Finish an assignment before 10:00 AM by waking up at 5:00 AM.

2. What are my alternatives?
   Use a built-in alarm app or a physical alarm clock.

3. What can I do now?
   I can set an alarm on my phone to wake up at 5:00 AM before I sleep.

4. How do I do it?
   I will open the clock app and set a new alarm to 5:00 AM. After that, I will save or confirm the alarm setting.

5. Perceived system state
   The clock app shows the new alarm set for 5:00 AM, indicating that it is turned on.

6. Interprets system state
   I see the alarm listed in the app, with a clear indication (a highlighted toggle switch) showing that the 5:00 AM alarm is active.

7. Evaluation
   I double-check the alarm list and look at the home screen to see if the alarm is displayed at the top. To ensure that the 5:00 AM alarm is correctly set and active.

Gulf of Execution and Gulf of Evaluation

Upon observation, the alarm list, home screen, and the highlighted toggle switch indicated that the alarm was set properly. Consequently, this clear feedback ensured that the user could easily see that the alarm was set and understood how the app works.

Therefore, the evaluation went smoothly.
