Study Notes

Usability Principles Overview

Emphasizes the importance of intuitive design for minimal user effort, errors, and confusion.
Quote from usability expert Steve Krug: “Don’t make me think.”
Usability is essential for graphic and digital product designers, especially with the rise of smart devices.

Principle 1: Learnability

Systems should be easy for new users to learn and intuitive.
Intuition means understanding without extensive instruction, exemplified by smartphone icons resembling real-world objects.
Learnability is assessed by how quickly new users can adapt to a system.

Principle 2: Efficiency

Efficient designs facilitate task completion with minimal steps.
Efficiency is defined by the time, effort, and resources required to complete tasks successfully.
High efficiency in interfaces allows users to achieve results with fewer clicks or inputs.

Principle 3: Memorability

Systems should be memorable, allowing users to easily recall operation after infrequent use.
Good memorability means users can navigate a product or website without needing to relearn it after a break.
Examples include high memorability of simple tools like staplers versus low memorability of USB cables.

Principle 4: Error Reduction and Forgiveness

Design should minimize user mistakes and provide clear paths to rectify them.
Good error handling includes explaining problems with actionable instructions, as opposed to cryptic technical messages.
Effectiveness in this principle is assessed by the frequency and recoverability of errors.

Principle 5: Satisfaction

User satisfaction reflects the pleasure experienced after completing tasks or using products.
Satisfaction can vary between similar functions; for instance, a cuckoo clock may provide more enjoyment than a digital clock.
High satisfaction enhances usability and contributes to positive user experiences.

Conclusion

The five usability principles (learnability, efficiency, memorability, error reduction/forgiveness, satisfaction) are foundational to creating user-friendly designs.
Good usability meets user needs and expectations, making it crucial for successful design.
