    • Design process: An iterative process that involves needs analysis, generating alternatives, using representations, interaction design, and user-centered design.

    • Norman's seven stages of user activity: A model for understanding and designing user activities in a digital system.

    • Human-computer interaction (HCI) is a discipline that focuses on designing, evaluating, and implementing interactive systems for human use.

    • HCI is concerned with the interaction between people (users) and computers.

    • HCI is composed of three parts: the human factor (users), the computer, and the interaction between them.

    • HCI aims to put people first, ensuring computer systems are easy to use, easy to learn, and error-free.

    • Approaches to HCI study vary, requiring a wide range of academic styles.

    • HCI experts need to be both creative and practical, placing design at the center of the field.

    • There are two main approaches to HCI: traditional and user-centered.

    • Traditional system development focuses on producing software, while considering the interface as just another software component.

    • User-centered design involves users at each step of the process, from requirement specification to implementation and evaluation.

    • User-centered development involves data collection, analysis, prototyping, design, and evaluation.

    • User-centered design advantages include user involvement, error detection, and quicker feedback.

    • User-centered design goals include understanding users and systems, limitations, and design acceptability.

    • HCI is important for various reasons, including preventing accidents, reducing the cost of training and support, and increasing sales.

    • Software development projects often fail due to reasons such as lack of senior management commitment, user involvement, user requirements specifications, poor project planning, and team problems.

    • Usability was born out of the need to prevent "friendly fire" during the Second World War.

    • HCI focuses on studying human factors and understanding user needs to create effective and efficient interactive systems.
