  Conversational agents have been showing lots of opportunities in healthcare
by taking over a lot of tasks that used to be done by a human. One of the major
functions of conversational healthcare agent is intervening users' daily
behaviors. In this case, forming an intimate and trustful relationship with
users is one of the major issues. Factors affecting human-agent relationship
should be deeply explored to improve long-term acceptance of healthcare agent.
Even though a bunch of ideas and researches have been suggested to increase the
acceptance of conversational agents in healthcare, challenges still remain.
From the preliminary work we conducted, we suggest an idea of applying the
personas of users' family members and the doctor who are in the relationship
with users in the real world as a solution for forming the rigid relationship
between humans and the chatbot.
