Study Notes

Human-Computer Interaction (HCI) Overview

HCI is an interdisciplinary field focused on the design, evaluation, and implementation of interactions between humans and computing devices.
It examines how individuals perceive, utilize, and behave with technology, particularly computers and smartphones.

Key Concepts

Interaction: An abstract model describing the methods of human interaction with computing devices for specific tasks, realized through hardware or software interfaces.
Usability: The ease and efficiency with which users can accomplish goals using a product, ensuring safety and correct task completion.
User Experience (UX): Encompasses the overall satisfaction a user derives from a product, integrating functionality, usability, aesthetics, and the product's fit with user lifestyle.

Goals of HCI

Functional Completeness: Systems must fully meet user requirements and possess all essential functions to achieve their intended purpose.
High Usability: Interfaces should allow users to understand easily, navigate clearly, and accomplish tasks with minimal effort.
Aesthetic Appeal: Attractive product design enhances user satisfaction and creates positive impressions.
Compelling User Experience: Combines usability, visual appeal, and emotional connection, fulfilling user needs in various dimensions.

Principles of HCI

Know the User: Design interfaces catered to diverse users across different backgrounds and abilities, promoting universal usability.
Understand the Task: Interfaces must accommodate different user methods for task completion, simplifying interactions for all users.
Reduce Memory Load: Minimize cognitive load by keeping short-term memory demands light, guiding users efficiently through tasks.
Strive for Consistency: Ensure uniformity in interface elements to foster user control and familiarity.
Remind Users: Use reminders and continuous feedback to refresh users' memories and maintain situational awareness.
Prevent Errors: Design interfaces to minimize confusion and cognitive overload, ensuring error-free operation.
Naturalness: Employ interfaces that mirror familiar everyday operations, enhancing intuitiveness through natural language and conceptual metaphors.

Affordances

Refers to cues that enhance user understanding and interaction, making interfaces intuitive and reducing the need for extensive learning.

Error Prevention Techniques

Incorporate design elements that help prevent mistakes and allow users to easily reverse actions when necessary.
