  A virtual embodiment can benefit conversational agents, but it is unclear how
their personalities and non-verbal behavior influence the User Experience and
Social Presence in Augmented Reality (AR). We asked 30 users to converse with a
virtual assistant who gives recommendations about city activities. The
participants interacted with two different personalities: Sammy, a cheerful
blue mouse, and Olive, a serious green human-like agent. Each was presented
with two body languages - happy/friendly and annoyed/unfriendly. We conclude
how agent representation and humor affect User Experience aspects, and that
body language is significant in the evaluation and perception of the AR agent.
