Designed and presented by:Hamza KhurshidAhmad GhunaimGhassan Knayzeh
General Outline
Introduction – Ghassan Knayzeh Birth: Blackboard to Prototype I – Hamza

Prototype II – Hamza Khurshid Alpha System – Ahmad Ghunaim
Maturity: Beta System – Ahmad Ghunaim Demonstration HCI application – Ghassan Knayzeh Conclusion – Ghassan Knayzeh
Introduction Outline
The Decline of Book readers
The Invention of E-Books: Not Quite Enough
The IDEA
The Decline of Book Readers
No time to read in the busy world. The hassle and bulk of the book. For some, reading is not just a past
time.
The E-Book
It came to help, BUT… Lacks the subtleties of the
conventional book: Pages replaced by the scroll (literarily) Writing on the book, or placing notes. Bookmarks Highlighting
In comes HagIT
Out target: Tablet PCs. PDA’s and other handheld devices.
HagIT: Attributes
Pages. But we provide a new way to browse
through the book, in addition to sequential browsing.
Notes Highlights Bookmarks
Evolution: Outline
Paper Prototype Components Feedback and Testing
Computer Prototype Components Feedback and Testing
Alpha System Components Feedback and Testing
Beta System Components Testing
The BirthOutline
IDEA Making a GUI utilizing the HCI principles
effectively What to do?
Visualizing what the program would do by making diagrams on black board
PAPER PROTOTYPE
Menu BarNavigation CirclesHistory BarAddress BarTool Bar
Navigation CircleTool for non-sequential browsing
Parts Circle
Chapter Circle
Section circle
History BarThe small circles on the screen
Provide continuous feedback of the current position in the book
Click to jump back to a required index
Address Bar
Conventional View the current location Change the position
Tool Bar
Functions: Notes Highlight Bookmark Clear Undo/Redo Choose Color Redisplay
Navigation Circle
Miscellaneous
Manage Notes/Bookmarks Quick Overview Edit Delete Add
Highlights
Feedback and Testing
Testing Briefing and Pretest Questionnaire Carry out Tasks Post Test Questionnaire
Feedback No next and previous buttons Some buttons without text More meaningful names of buttons
(Manage Notes/Manage Highlights)
Computer PrototypeHagIT GUI
Better and faster platform forevaluation
Usability Test Plan
1. Laboratory Experiment
2. Cognitive Walkthrough
3. Heuristic Evaluation
FeedbackWeaknesses
Users couldn't access the history bar once viewing a page
The color contrast paused a visual problem
No verification whether the book was closed or not
No innovation (Surprising)
FeedbackStrengths
Usable Functions clearly marked in their
appropriate menus The system uses a lot of familiar
symbols and conventions in order to convey a sense of familiarity
Alpha System
Improvements
Programming Language: Java Better loading of books. More, yet incomplete,
implementation of functions Dynamic NavCircles and History Bar Books only in XML format
Functionality
Highlight Notes Bookmarks
Feedback
NavCircle and History Bar disappearing at the page level (again)
Functions not worth doing if they are not done correctly
Comparison with existing systems Highlights/notes already available
Many bugs
Beta System
Improvements
Programming Language: Python Functions properly implemented NavCircles can be retrieved at the
page level Minimized bugs.
In short it works…
DEMO
HCI Principles
TESTING, TESTING, and TESTING AGAIN.
Consistency with standards User control and freedom Match between the system and the
real world
Testing
Formal Testing of the: Paper Prototype Computer Prototype Alpha System
Informal Testing: 2 Resident testers available throughout
the designing process.
Consistency and Standards
Standard Buttons and Menus Menu bar, Tool bar
Standard Tasks Bookmarking, moving through pages.
Consistency in the NavCircles
User Control and Freedom
Providing the user 3 ways of browsing the book: The conventional page-by-page The Address Bar The NavCircles
Other examples: Providing the user the ability to undo
there actions easily.
HagIT Vs. Real Books
Match: Pages Bookmarks Notes Highlights
At End of the Design
Designing is not equal to coding.
It is a multi-stage, iterative process of designing and testing.
In Conclusion
Reading is an indispensable function.
Help the busy “integrate” reading back into their “system”.
Thank You…
…We will take any questions now.
