One of the most complex tasks while designing a conversation is to create natural interactions with our users. However, there is one process called a contextual design that helps us to create these natural conversations. With the contextual design, you can design your conversation depending on the current situation of our users.
For example, if the user is a first-timer using our Google Action, we will tell him/her a different welcome message than if he/she access it for the second time. Another example is the following one: if the user is from one City, we will provide information related to that city accessing geoinformation. Contextual design is one of the keys of Conversational AI.
