I don't think this is undirected.

Google doesn't talk about it much, but the founders are still interested in the kind of non-dystopia cyberpunk future where a personal assistant is virtually perched on your shoulder, helping you get through your day like a non-invasive cyber-butler. It's the notion that drove Glass and drives Home and Assistant.

Having an in on medical observation technology fits into that mold. I doubt they'd publicize that as their goal until and unless they have something to show for it though.
