[If I don't think of an alternative, yes it is. I'd magically expand my field of vision but I think it'd make me twitchy, reacting to things I shouldn't be able to see...] Think, think. [I'll take your directional feeling and make it buzz, I think. Faster for the more intently someone's looking at me - someone scanning a crowd I'm in or a stationary security camera in the grocery store will barely register, someone actually spying on me will vibrate like a bell. And I'll fuss with the distance indicator to add a dimension so I know what it is that's looking at me. And I'll run at one-point-five by default while I get used to it.]
