Human Computer Interaction (HCI);



i): Introduction to Human Computer Interaction(HCI):

Human-Computer Interaction (HCI) is a multidisciplinary field that focuses on designing
and improving the interaction between humans and computers. HCI combines insights
from psychology, computer science, design, and sociology to create interfaces that are
intuitive, user-friendly, and efficient. The goal of HCI is to enhance user experience,
productivity, and accessibility.

ii): Key Principles of Human Computer Interaction(HCI):



1. User centred Design: Designing interfaces that prioritize user needs, goals, and
behaviours.

2.Usability: Ensuring interfaces are easy to use, efficient, and error-free.

3.Accessibility: Designing interfaces that are accessible to diverse users, including those
with disabilities.

4.Feedback: Providing users with clear and timely feedback about their interactions.

5.Consistency: Maintaining consistency in design and layout to reduce user confusion.



iii): Human Computer Interaction (HCI) Design Process:

1.User Research: Conducting research to understand user needs, goals, and behaviours.

2.Personas: Creating user personas to guide design decisions.

3.Wireframing: Creating low-fidelity sketches of interface layouts.

4.Prototyping: Creating interactive prototypes to test and refine designs.

5.Usability Testing: Conducting testing to identify usability issues and areas for
improvement.
