1. Comp7620 - Human Computer Interaction Project1 COMP 7620 Human Computer Interaction Project Title: A Web-Based Database Application for Housing Management: The use of “Norman’s Gulf of Evaluation” as a means to avoid Software Interfaces Problems and rendering Interfaces more Interactive Student: Mohamed Riduan Abid

2. Comp7620 - Human Computer Interaction Project2 Idea Dehind The Use of Norman’s Concept of « Gulf of Evaluation » to render Interfaces more Interactive

3. Comp7620 - Human Computer Interaction Project3 Norman’s 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

4. Comp7620 - Human Computer Interaction Project4 Norman’s Model Gulfs 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

5. Comp7620 - Human Computer Interaction Project5 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

6. Comp7620 - Human Computer Interaction Project6 What does this project consists on?  A Web-Based Database Application  Housing Management Technolgy used: ASP.Net (Activer Server Pages)  Handling the Server-Side Code ADO.Net (ActiveX Data Objects)  Managing Connections to Datawas C# (C Sharp)  Codehind for Implmenting Business Rules IIS (Internet Information Server)  As a Web Server MS Access  As s DBMS

12. Comp7620 - Human Computer Interaction Project12 Other Feedback Instances Updating a non-Existing Entry

13. Comp7620 - Human Computer Interaction Project13 Other Feedback Instances Inserting an Entry

14. Comp7620 - Human Computer Interaction Project14 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!
