Looking into zero-UI concepts, a chatbot will be a very suitable solution. I got some inspiration from the HuggingFace chatbot, a social AI featuring chit-chat with users, selfie trading, and character customization. The bot doesn't try to disguise itself as a human because it sometimes will provide choices of response for users, which does not resemble human texting conversation. However, this is a smart and effective way to guide the users in the interaction, especially if the bot is not able to handle out-of-range questions.
Is this a good/useful/informative piece of content to include in the project? Have your say!
