The Eight Golden Rules of Interface Design

1. Strive for consistency 2. Seek universal usability 3. Offer informative feedback 4. Design dialogs to yield closure 5. Prevent errors 6. Permit easy reversal of actions 7. Keep users in control 8. Reduce short-term memory load

What Must, Can, & Should Be Done?

WCAG Principles

1. Information is Perceivable
2. Interface is Operable
3. Information is Understandable
4. Reliable and Robust

Source

3 Layers of Concern

1. LMS/HTML Page
2. Documents / Materials
3. Apps/Tools/Plugins

3 Big Concerns:

1. Images are tagged
2. Text is organized and readable
3. Videos are closed captioned

You ≠ User

Affective “Three” Experience

AX

1. Aesthetic Experience: Sensory Delight
2. Emotional Experience: Affect and Engagement
3. Experience of Meaning: Symbolic, reflective, or long-term connections

2. Shneiderman’s 8 Golden Rules
3. Hansen’s 4 Principles
4. Educational Theories
5. Activity Theory
6. Accessibility (WCAG and OIT)

8. Affective Three

User-Centered Design

Another cornerstone of HCI is the principle of user-centered design. This approach places the user at the forefront of the design process, ensuring that their needs, preferences, and limitations drive the development of the system. In user-centered design, feedback loops are critical, and iterative design processes are employed to refine the user experience continuously.
