Study Notes

Chapter 5: User Actions and Controls

User actions and controls are a crucial part of human-computer interaction.
Entering information involves forms, dialogue boxes, and data input.
Issues with similar layouts and alignment (e.g., different label lengths) exist.
Logical layout and task analysis (chapter 15) shape information entry. Natural order is often top-to-bottom, left-to-right, depending on a culture.
Keyboard entry tab order is also important.
Understanding what is active and what is passive in the user interface is key.
Knowing how to select, click, and type is important to understand the workflow.
Style consistency aids navigation (e.g., underlined links).
Standards for action icons and labels are necessary for clear communication (e.g. bolded text for current actions).

Affordances

Affordances are psychological terms related to physical objects.
Shape and size suggest actions (e.g., a mug handle suggests grasping).
Cultural factors affect how objects are interacted with (e.g., buttons imply pushing).
Screen objects, like button-like objects, imply mouse clicks.
Physical likes suggest objects for physical interactions (e.g., clicking).
Icons and buttons should properly reflect their intended function.

Presenting Information

Purpose matters when presenting information. Understanding the needed information is essential.
Appropriate sorting (e.g., column, numeric, alphabetic) and textual vs. graphic representation are crucial.
Using techniques such as scatter plots and histograms when presenting information are important.
Presentation principles are vital for effective communication. Interactive elements can enhance information presentation.

Aesthetics and Utility

Aesthetics (e.g., pleasing design) and utility (e.g., functionality) can conflict when designing an interface.
A pleasing aesthetic can increase user satisfaction and productivity.
Mixed visual styles may be hard to distinguish, while clean designs might fail to differentiate enough.
Backgrounds behind text could make the text hard to read, although it may look pleasing.
Aesthetics and utility can be balanced to create effective designs.

Color and 3D

Color and 3D effects can be used to create more engaging and informative displays, but they can be misapplied.
Limited color palettes on older monitors can lead to misuse.
Color blindness must be considered. Color use requires careful thought.
Color needs to be used strategically to reinforce information.
3D can be used effectively to represent physical information and some graphs, but over-use should be avoided. 3D pie charts, 3D text in perspective could cause issues.

Bad Use of Color

Overuse without proper reason (e.g., kid-oriented interfaces) negatively affects interface design.
Color blindness needs to be considered for design.
Poor use of contrast can harm user experience.
Adjusting monitors to grey scale helps ascertain if the interface is readable despite color.

Across Countries and Cultures

Localization and internationalization are important for global interface design.
Changing interfaces for various cultures and languages is key.
Symbols and icon choices should accommodate varied cultural backgrounds.
Using a language-resource database instead of literal text improves localization.
Design changes often relate to deeper aspects such as cultural assumptions, values, and symbols meanings across cultures.

Prototyping

Iteration and prototyping are crucial parts of interface design.
You rarely get an interface correct on the first try.
Prototyping should include design, prototype building, evaluation, and re-design steps.
Successful prototyping involves addressing issues and improving the interface in iterations for better functionality.
Pitfalls in prototyping involve issues like insufficient initial design or failing to identify and fix design issues. Initial start-point and clarity on design issues needing improvement both contribute to proper prototyping.
