My local hospital has one of these in the lobby. It's scary quite how realistically 'hologram-like' it looks from a distance: from the corner of my eye, I took it for a real person at first, and only realized that it didn't look quite fully 3D when I looked directly at it. Once you get closer up you see that it's a rear projector with a rigid free-standing screen precisely cut to the outline of the avatar, but even from that close it still looks surprisingly good. Kudos to whichever company makes these (unfortunately the article doesn't mention which, and I didn't notice any branding on the one I saw). It'll be interesting to see these if they get them to be minimally interactive, to the point where you could ask them "Where is the check-in desk?" and have them reply with pre-recorded directions.
