Analogy

Imagine you are an architect designing a house. Before you start drawing the blueprints, you need to understand the needs and preferences of the people who will live in the house. You gather information about their lifestyle, the number of rooms they need, and their aesthetic preferences. This process of gathering information is similar to the discovery phase in HCI. Once you have a clear understanding of the users' needs, you can start designing the house using a framework. The framework provides a structured approach to the design process, ensuring that the house meets the needs and preferences of the users. During the construction of the house, you observe how the users interact with the space to identify any usability issues or design improvements. This observation phase is similar to the collection - observation phase in HCI. Finally, you gather feedback from the users to further refine the design and make any necessary changes. This feedback gathering process is similar to the elicitation phase in HCI. By following this systematic approach, you can create a house that is functional, aesthetically pleasing, and tailored to the needs of the users.
