1. 6. What are the 2 types of interaction used in Human Computer Interaction.
1.1. Direct Manipulation:
1.1.1. Involves interacting with objects on the screen using actions like clicking, dragging, or touching, providing immediate visual feedback (e.g., dragging files into a folder).
1.2. Indirect Manipulation:
1.2.1. Involves using commands or input devices like keyboards to interact with the system, often requiring a more abstract understanding (e.g., typing commands in a terminal).
2. 1.What is Human Computer Interaction (HCI)?
2.1. Human-Computer Interaction (HCI) is an interdisciplinary field that focuses on the design, evaluation, and implementation of interactive computing systems for human use. It also studies the various phenomena surrounding these systems. The primary goal of HCI is to make these interactions as effective, efficient, and satisfying as possible.
3. 2.Why HCI is important?
3.1. Human-Computer Interaction (HCI) is important for several reasons, each contributing to the overall goal of creating more effective, efficient, and satisfying interactions between humans and technology.
4. 3.What is user interface?
4.1. A user interface (UI) is the space where interactions between humans and machines occur, enabling users to control and communicate with a system.
4.1.1. EXAMPLES :
4.1.2. Graphical User Interface (GUI): Example: The desktop environment of a computer with icons, windows, and buttons (e.g., Microsoft Windows, macOS).
4.1.3. Command Line Interface (CLI): Example: Terminal or command prompt where users type text commands (e.g., Bash on Linux, Command Prompt on Windows).
4.1.4. Touch User Interface (TUI): Example: Smartphone touchscreens with gestures like swiping and tapping (e.g., iOS on iPhones, Android on Samsung phones).
4.1.5. Voice User Interface (VUI): Example: Voice-activated assistants (e.g., Amazon Alexa, Google Assistant).
4.1.6. Web User Interface (WUI): Example: Web pages with navigation menus, forms, and buttons (e.g., an online shopping site like Amazon).
5. 4.Why do we care about the design?
5.1. We care about design because it directly impacts user experience, making products more intuitive, attractive, and accessible. Good design can increase efficiency, reduce errors, and foster emotional connections, leading to greater user satisfaction and loyalty. It also helps differentiate products in the market, supports brand identity, and can drive business success by attracting and retaining customers.
6. 5.What is ergonomics role in interface design?
6.1. Ergonomics in interface design ensures that products are comfortable, efficient, and safe for users, reducing strain and enhancing usability.
6.1.1. EXAMPLES :
6.1.2. A keyboard designed with an ergonomic layout and wrist rest can prevent repetitive strain injuries and increase typing comfort, making it easier for users to work for extended periods.
