3. Why is interface design often referred to as dialog design?

Interface design is often referred to as dialog design because it involves creating a two-way communication between the user and the system. Just like in a conversation, the interface should be able to effectively transmit information to the user and also collect input from the user. It is a dialogue between the user and the system, where the user interacts with the interface to accomplish a task or receive information. By designing the interface as a dialogue, designers can ensure that the system is user-friendly, intuitive, and responsive to user needs.
