What is a user interface?
Part of the system with which the user interacts.
A usable system should be:
Easy to use
Easy to learn
List the results of a usable system. RIE
Reduced mistakes
Increased user satisfaction
Efficient and accurate task completion
List the principles for user interface design.
Layout
Content awareness
Aesthetics
Usage level
Consistency
Minimize user effort
List the 3 boxes that a screen is often divided into in layout concepts.
Navigation area (top)
Status area (bottom)
Work area (middle)
List the properties areas should remain consistent in.
Size
Shape
Placement for entering data
Reports presenting retrieved data
List all the necessary functions in content awareness.
Breadcrumbs
Menus that show where you are
Titles in all interfaces
List all the necessary functions in Aesthetics.
Design text carefully
Use colors and patterns carefully
Use colors to separate items
List all the necessary functions in Aesthetics.

Include adequate spacing between objects
List the path to a successful user interface. UODDE
Understand the Users
Organize the Interface
Define Standards
Develop Prototypes
Evaluation / Testing
List the different types of personas to develop characterization of various user groups.
Interests
Typical behaviors
Goals & objectives
Expectations
How can one organize the interface?
Through the use of Interface Structure Diagram (ISD)
Site map
Study the ISD and the site map.
Chapter 9, Page 34, 36
When defining standards, what are the common interface elements to ensure consistency?
Interface metaphor
Interface objects
Interface actions
Interface icons
Interface templates
What is interface design prototyping?
A simulation of screens, forms or reports.
List the common methods of interface design prototyping.
Paper sketches
Wireframe diagrams
Storyboarding
Wire flow diagrams
HTML prototype
Language prototype
Study the common methods of interface design prototyping diagrams.
Chapter 9, P39, 40, 41
List the interface evaluation methods.
Heuristic evaluation
Walkthrough evaluation
Interactive evaluation
Form usability testing
What is heuristic evaluation?
Comparing design to checklist
What is walkthrough evaluation?
When a team simulates movement through components
What is interactive evaluation?
When users try out a system.
What is formal usability testing?
It is a detailed use of special lab testing that is expensive.
What are the basic principles of navigation design?
Assume users have not read a manual
All controls should be clear and understandable.
Prevent mistakes
Use consistent grammar order
What are some important menu tips to consider?
A menu should not contain more than 8 items
A menu should have 2 mouse clicks maximum to perform an action
Group similar items within a menu item
List the common menu formats. MID PIT
Menu bar
Drop-down menu
Popup menu
Tab menu
Icon tool bar
Image map
List the common message types. CHADE
Error message
Confirmation message
Acknowledgment message
Delay message
Help message
What is the goal of input design?
Simply and easily capture accurate information for the system
Differentiate between online and batch processing.
Online processing immediately records the transaction in
database.
Batch processing collects inputs over time, holds them
temporarily, and then processes all the transactions at one
time in a batch
List the pros of capturing data at the source.
Reduces duplicate work
Reduces processing time
Decreases cost
Decreases probability of error
How can we obtain source data?
Bar code scanner
Smart cards
RFID tags
List the types of input validation.
Completeness check
Format check
Range check
Check digit check
Consistency check
Database checks
Study the input tips.
