HCI & UX: An Overview

What is HCI (Human-Computer Interaction)?

Human-Computer Interaction is a multidisciplinary field focused on the design, evaluation, and implementation of interactive computing systems for human use.

It studies how people interact with computers and technology, aiming to create interfaces that are efficient, effective, and user-friendly.

Core Concepts of HCI

Usability

Ensuring interfaces are intuitive, easy to learn, and efficient to use.


Accessibility

Designing systems for users of all abilities, including those with disabilities.


User Experience (UX)

Focusing on users’ emotions, satisfaction, and engagement with a product.


Interaction Design

Creating meaningful and useful interactions between users and products.


User-Centered Design (UCD)

Iterative design that prioritizes user needs and feedback.

HCI and UX

HCI and UX started merging as the digital landscape evolved, with HCI providing the theoretical foundation and UX focusing on practical application. 

HCI’s research-driven approach blended with UX’s focus on holistic, user-centered design. Emerging fields like Interaction Design (IxD), Service Design, and CX (Customer Experience) enriched UX practice. 

The convergence of HCI and UX reflected the need for end-to-end experiences, prioritizing user satisfaction and seamless interactions.

How HCI Influences UX

Research Methodologies

HCI’s methods, such as usability testing, heuristic evaluation, and cognitive walkthroughs, are central to UX.


Design Principles

HCI’s focus on usability, consistency, and user-centered design guides UX practices.


Prototyping and Evaluation

HCI’s iterative design processes are foundational in UX design cycles.


Accessibility and Inclusion

HCI’s emphasis on accessibility has become a core principle in UX.

Modern HCI vs. UX

HCI provides a deep understanding of human behavior, cognition, and interaction. UX translates these insights into real-world designs and product experiences. 

HCI’s focus on research and theory has enriched UX design practices, shaping how we interact with technology today.
