Nonverbal communication is a crucial element of this – in both regular and fallback experiences – as it helps the agent convey information in a way that feels more instinctive and familiar to us. Dogs do an amazing job of this – they nonverbally communicate with us in a way that's clear and easy to understand, and it's important for the agent to do the same. Nonverbal communication can be a far less intrusive interface than voice alone, and can attract the user's attention in a subtle, yet effective way. For example, when a user calls out ElliQ's wake word, ElliQ's face lights up and head bends forward, leaning in to indicate listening. This endearing behavior not only draws the user in, it also explicitly conveys to them that their request or attempted interaction was indeed successful, and that they should proceed accordingly.
