Human-Computer Interaction (HCI) is the study of how people interact with computers and technology to create meaningful experiences.

Human-Computer Interaction (HCI) is a field of study that focuses on the design, development, and evaluation of interactive systems for human use. It is an interdisciplinary field that combines elements from computer science, psychology, cognitive science, and other disciplines to create user-friendly products. HCI is an important part of product management because it helps to ensure that the product meets the needs of its users. Product managers must consider how users interact with their product and how they can make it easier for them to use. This includes designing user interfaces that are intuitive and easy to use, as well as providing feedback and support when needed. Additionally, product managers must consider how users will interact with their product in different contexts and environments. By understanding user behavior and preferences, product managers can create products that are tailored to their users’ needs.

Examples of HCI include: 1. Graphical User Interfaces (GUI): GUI's are the most common type of HCI, and involve the use of icons, menus, and other visual elements to interact with a computer. 2. Voice Recognition: Voice recognition systems allow users to control computers using their voice. 3. Gesture Recognition: Gesture recognition systems allow users to control computers using hand or body movements. 4. Natural Language Processing: Natural language processing systems allow users to interact with computers using natural language instead of code or commands. 5. Virtual Reality: Virtual reality systems allow users to interact with virtual environments in a 3D space using special hardware such as headsets and controllers.
