The Blind Spots of Personal Sensor Networks

I haven't actually seen reference to that in any sci-fi movies or I didn't think about it reading the book either but all this data you're collecting that seems like a strange behavior human being. James is waving his hand I'm going to have a reference I was gonna prove that I've been doing more the book than you because I was there is a mention of personal scale sensor networks they don't really show up except for a scene in the original Star Trek where a character ambassador comes on board and she's got this sort of beautiful dress that turns out to be a sensor network that allows her to see since she's blind.
