Drivers using Google glass

[zinthorne]

So I have seen several highlight videos where teams had their human player wear a pair of the Google glasses to record video. Well this got me thinking about having the driver of the team wear a pair to display information about the match without having to look down at the laptop or hearing it. This information could include time left in the match, video feed from a camera on the robot, or telling what positions certain functions of the robot are in. Even hot goal detection could be done theoretically. Is this legal or even possible? And what are your ideas on actually doing it?
