Glass is a sousveillance technology according to Steve Mann's definition. But also a surveillance technology due to its link with Google.

Edit: found an article where he discusses Glass in this regard, interesting read http://techland.time.com/2012/11/02/eye-am-a-camera-surveill...

Then I stand corrected. Thanks.

edit: I do keep harping on about it, but his book "Intelligent Image Processing" is worth a read for more info on how the Eyetap works (amongst other topics).
