All Talk and No Buttons: The Conversational UI

After all, a lot about design is telling a good story, and building a robot is an even purer version of that. It's probably rather empty, but it already has some familiar controls on it: an options menu, a settings button, a big button for starting something new. It's easy to assume our robot is operating inside a pure messaging or voice platform, but increasingly this is not the case: Amazon Echo is controlled by voice, but has a companion app. As users become more familiar with chat robots, they will form expectations about how these things should work and behave.
