Now they are. Mostly they're doing it with happy fun talk, but they are following.
Here is a good example. It's the blog for Gilbert Guide, a nursing care directory. It calls Always-On applications "ambient intelligence environments," which is a fancy way of saying that sensors track the patient's activities, reducing the load on caregivers.
I don't object to any of this, including the renaming of the technology to something complex and forbidding. What I object to is the presumed sales method and the power relationships built inside it.
When Always-On applications are sold as a system, to the family, the patient loses power (and so does the family -- it's a system sale like buying the nursing home itself). When the application is sold directly to the patient or the family, when you're able to get a heart or sugar monitor at BestBuy, or get the plans for a complete home makeover at Make Magazine, now you have the power and control.
