Exactly, I am a doctor. No way the hospital would allow me to wear an AW with a camera, I don't think, as we are not at that point yet, so I can only speculate. Also, I do not think my private patients would want me to have a camera on my AW while consulting with them.
This would be a huge HIPAA violation (I would imagine), and I cannot (at this moment) think of anyway Apple could address it. This of course is if we are talking about a camera built into the AW. This article is about a band with a camera, in that case you just change your band to a normal band while at work and then put the camera band back on when you are done.
If the mere presence of the camera is a problem, even though it's not recording, then you're already violating HIPAA by having a Watch with microphones that can record a private conversation.
