2. introduction • Computers play a vital role in our daily lives — at school, work, and home. • Interaction with a computer means communicating and exchanging information with it. • The goal of human-computer interaction is to make technology more efficient, comfortable, and easy to use. • Modern devices now support multiple types of interaction: voice, touch, motion, and visual input.

3. What is human - computer interaction ? Definition: Human–Computer Interaction (HCI) is the study of how people use and control computers. • It focuses on the design, use, and evaluation of computer systems • HCI helps create interfaces that are simple, intuitive, and user-friendly. • Example: Using a smartphone screen or giving a command to a virtual assistant.

4. Components of interaction 1 . User: The person who operates the computer. 2. Hardware: Physical parts such as monitor, keyboard, and mouse. 3. Software: Programs and systems that run on the computer 4 . Interface: The connection between user and system — where communication happens.

5. Input dev ices • Devices that allow the user to send data or commands to the computer. • Examples : • Keyboard – for typing text • Mouse – for pointing and clicking • Microphone – for voice input • Scanner – for copying images or documents • Webcam – for capturing photos or video • Touchscreen – for direct interaction with the display

6. Output dev ices • Devices that show or deliver information from the computer to the user. • Examples: • Monitor – displays text, images, and videos • Printer – produces hard copies of documents • Speaker – plays sounds or music • Projector – shows visuals on a large screen • Output makes it possible for users to understand computer results easily.

7. Types of interaction • Graphical User Interface (GUI): Uses icons, buttons, windows, and menus (e.g., Windows, macOS). • c ommand Line Interface (CLI): Uses text commands; preferred by programmers. • Touch Interface: Found on tablets, phones, and ATMs. • Voice Interface: Uses speech recognition for commands. • Gesture Interface: Detects body movements or hand gestures.

8. Graphical user interface ( gui ) • The GUI made computers accessible to everyone — no need for programming skills. • It uses visual symbols instead of written commands. • Elements include: • Icons (represent programs or files) • Menus (list of options) • Windows (separate areas for multitasking) • Buttons (for quick actions) • Example: Clicking the recycle bin icon to delete files.

9. Importance of human-computer interaction • Makes computers easier and faster to use. • Reduces mistakes and improves efficiency. • Encourages innovation in technology design. • Helps users with disabilities access computers (accessibility tools). • Improves learning, communication, and entertainment experiences.

10. conclusion Interaction with computers is now a part of everyday life. From typing and touching to speaking and moving — we communicate with machines in many ways. The future of human–computer interaction promises smarter, faster, and more natural connections between people and technology. Understanding how we interact helps us design a better digital world.
