Norman’s Model

Already Covered in Chapter 3The most influential Model in Human-Computer InteractionWhy? It is very close to our intuitive

understanding of the interaction between human user and computer

Norman’s ModelGulfs of Execution and

Evaluation

Reminder Gulf of Execution

The difference between user’s formation of the actions to reach the goal and the actions allowed by the system

Gulf of Evaluation The distance between the physical

representation of the system state and the expectation of the user

What is this Project About?

About the Gulf of Evaluation We are trying to make an Inteface

an interactive one by allowingfor as mush as possible appropriate feedbacks in order to prevent the user from going on the disapponting task of guessing the system state. I.e, guessing what happened

Conclusion

Indeed Norman’s idea of the Gulfs is an exceedingly interesting measure But for an additional reason that I gained from this course/project: Gulfs of Evaluation/Execution are NOT

benificial ONLY for users but for developpers as well!
