This document summarizes 7 experiments conducted to design and test a user-friendly online quiz interface. The experiments focused on domain analysis, conceptual modeling, screen design effectiveness, direct and indirect manipulation strategies, human consideration factors, menu types, window selection, and screen navigation/flow. The goal was to reduce cognitive workload and ensure intuitive, predictable, and visually pleasing interaction for users with only basic English skills.
2. User-friendly
• Understanding the needs of user is very
essential for designing a system.
• Users are most important part of the systems.
• Advantages
– Easy to understand
– Can be used by anyone
– No additional knowledge required.
– Only basic knowledge of English.
7.  Interface Design goals
• The aim is to reduce visual, intellectual, memory,
and motor work.
• No difficulty in locating any piece of information
with the help of catchy icons and simple expressions.
 Organizing elements clearly and
meaningfully
• Clear and clean organization of display elements
makes it easier to recognize the screen’s essential
elements.
• Avoidance of clustering and random placement of
icons.
8.  Consistency
• Users will commit fewer errors when the visual aspects of
information sites are consistent.
• Increase in user satisfaction and reduction in learning time.
 Navigation and Flow
• Navigation should be obvious and easy.
• The direction of movement should be consistent and rhythmic.
11. EXPERIMENT 3
To study and implement
direct and indirect
manipulation strategies of
GUI design.
12.  Direct Manipulation
• Options and actions are continuously visible.
• Actions are rapid and incremental with visible display of results.
 Indirect Manipulation
• Sometimes when it is difficult to conceptualize all screen objects in the
graphical system due to authentication parameters.
• It may be difficult for people to learn and remember all the necessary
operations and actions.
15. EXPERIMENT 4
To study and implement
the importance of Human
Consideration in GUI
Design
16. Organizing screen elements.
• Some of the parameters to be considered are balance(alignment),
regularity, predictability, sequentiality, simplicity, groupings etc.
Choosing colors.
• Color adds dimension and realism to screen usability.
• It attracts people’s attention.
18. EXPERIMENT 5
To study and implement
Effectiveness of different
types of Menus in screen
design
19. Structure of menus differ from very
simple to very complex.
• We have basically used Sequential Linear Menus to make our system
look simple and user friendly.
• We have also employed certain functions of menus like navigation to
a new menu, data or parameter input etc.
23. Navigation and flow.
• Navigation should be easy to accomplish.
• It should be a little logical and predictive.
Visually pleasing composition.
Balance
• An equilibrium or stability is required within the design elements.
Symmetry.
Legibility and Readability.
