Human Computer Interaction (HCI) Example

Watch the video clip of a person using the Countdown Website. See if you can find example of the 10 Heuristic Principles within the video. (There is no sound on this video)

They are:
1. Visibility of system status
2. Match between system and the real world
3. User control and freedom
4. Error prevention
5. Help users recognize, diagnose, and recover from errors
6. Consistency and standards
7. Recognition rather than recall
8. Flexibility and efficiency of use
9. Aesthetic and minimalist design
10. Help and Documentation

Take screen shot of each heuristic and describe how it helps the user.
