Similarly to new real-life situations, there are often times when users feel they need a guide in Virtual Reality.
When should I replace my bandages after surgery? Do you know where I can buy medical gauze? How long will my follow up appointment take? Is it even really necessary? Is this much bruising normal?
Each of these questions are very important and need to be answered by a qualified professional. Each of these questions are also common after almost every surgery. Support staff are often capable and qualified to answer each of these questions, but patients typically prefer to speak with the attending surgeon or doctor.
With conversational AI many common questions are easily answered, and patient anxiety greatly eased, day or night, by your avatar (usually a digital version of you, not necessarily a video).
