There has been much talk about the powerful Google Glass user experience, but little attention was paid to the experience of everyone else who are around people wearing Google Glass. Like second-hand smoking or loud cell phone use in public places, Google Glass creates strong passive user experience by making people feel uneasy as their faces are tagged, indexed, stored and searched in an online cloud involuntarily, sometimes without the Google Glass user even requesting it. Passive user experience is one reason that many places have set up rules to ban Google Glass use.
