Dialogue diagramming is a formal method for designing and representing human-computer dialogues using box and line diagrams. The three sections of the box include: Top—contains a unique display reference number used by other displays for referencing it, Middle—contains the __________ or description of the display, Bottom—contains display reference numbers that can be accessed from the current display.

Study Notes
Designing Interfaces and Dialogues
- The design of interfaces and dialogues defines the manner of human-computer interaction, providing a uniform structure for finding, viewing, and invoking system components.
- A good human-computer interface should provide a uniform structure for finding, viewing, and invoking system components.
The Process of Designing Interfaces and Dialogues
- The process of designing interfaces and dialogues is a user-focused activity that involves prototyping methodology, including:
- Collecting information
- Constructing a prototype
- Assessing usability
- Making refinements
- To design usable interfaces and dialogues, one must answer the who, what, where, and how questions.
Deliverables and Outcomes
- The deliverables of designing interfaces and dialogues include:
- Creation of a design specification
- The specification includes:
- Narrative overview
- Sample design
- Testing and usability assessment
- Dialogue sequence
- Dialogue sequence refers to the ways a user can move from one display to another.
Interaction Methods and Devices
- Human-computer interfaces define the method of interaction, which includes:
- Command language interaction
- Menu interaction
- Form interaction
- Object-based interaction
- Natural language interaction
- Each interaction method has its own characteristics, such as:
- Command language interaction: uses explicit statements to invoke operations
- Menu interaction: provides a list of system options for user selection
- Form interaction: uses data fields formatted like paper-based forms
- Object-based interaction: uses symbols to represent commands or functions
- Natural language interaction: uses conventional spoken language as input
Hardware Options for System Interaction
- Hardware devices used to support interaction include:
- Keyboard
- Mouse
- Touch screen
- Light pen
- Joystick
- Graphics tablet
- Trackball
- Voice
- Each device has its strengths and weaknesses, and selection should be guided by the needs of the user.
Designing Interfaces
- Designing interfaces involves:
- Structuring and controlling data entry fields
- Providing feedback
- Designing online help
- Forms should have standard formats, use left-to-right, top-to-bottom navigation, and provide flexibility and consistency.
Designing Layouts
- Designing layouts involves:
- Using standard formats similar to paper-based forms and reports
- Providing left-to-right, top-to-bottom navigation
- Flexibility and consistency
- Several rules should be considered when structuring data entry fields, including:
- Never requiring data that is already online or can be computed
- Providing default values when appropriate
- Making clear the type of data units requested
- Using character replacement when appropriate
- Providing formatting examples
Providing Feedback
- Providing feedback involves:
- Status information: keeping the user informed of what's going on
- Prompting cues: telling the user when input is needed and how to provide it
- Error or warning messages: informing the user of errors or warnings
Providing Help
- Providing help involves:
- Placing yourself in the user's place
- Designing usable help messages, including:
- Simplicity
- Organization
- Showing the user how to perform an operation
Designing Dialogue
- Designing dialogue involves:
- Designing the dialogue sequence
- Building a prototype
- Assessing usability
- Dialogue design involves:
- Consistency
- Error handling
- Shortcuts and sequence
- Reversal
- Feedback
- Closure
- Ease
- Dialogue diagramming is a formal method for designing and representing human-computer dialogues.
Designing Interfaces and Dialogues in Graphical Environments
- Graphical interface design involves:
- Becoming an expert user of the GUI environment
- Understanding available resources and how they can be used
- Understanding standards for menus and forms
