The paranoiac in me wants to suggest that they would be recording everything and sending it home. But there are probably legal issues with that, so instead I will suggest that you are going to be interacting with a device on your face that sends back information about every query you make with it.

If you are uneasy about cell phones recording your position at all times, this is probably worse.
