COMP 7620 Human Computer Interaction

• Project Title
• A Web-Based Database Application for Housing
  Management
• The use of Normans Gulf of Evaluation as a
  means to avoid Software Interfaces Problems and
  rendering Interfaces more Interactive
• Student
• Mohamed Riduan Abid

2
Idea Dehind

• The Use of Normans Concept of  Gulf of
  Evaluation  to render Interfaces more Interactive

3
Normans Model

• Already Covered in Chapter 3
• The most influential Model in Human-Computer
  Interaction
• Why?
• It is very close to our intuitive understanding
  of the interaction between human user and
  computer

Normans ModelGulfs of Execution and Evaluation

• Reminder
• Gulf of Execution
• The difference between users 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

5
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 Normans 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!
