... arrived and is here to stay.
Noel Ackerson, a 33-year-old software developer in Washington DC, who has been trialling Google Glass over the past several weeks, claims to have developed his own "common sense" etiquette for Google's new digital headset.
Glass, which sites a small computer screen above one eye, also features a built-in motion sensor, camera and microphones, acting as an extension of a person's smartphone.
It enables the user to take photos and record videos by touching the side of the device or speaking commands aloud, as well as allowing him/her to give other web users access to the device's camera so they can "see" what the wearer sees.
Developer Ackerson's self-imposed niceties require him to take Glass off in a public restroom, in a movie theater and in casinos, where having such a device could give him an unfair advantage.
Says Mr Ackerson: "Google Glass has technology that isn't new, and the etiquette we've applied to existing technologies should roll into it."
Glass-wearers also can use the device to make phone calls, access Google's web search, get turn-by-turn navigation information and receive text messages on the screen, as well as send texts using their voice.
Currently unavailable to the general public, Glass is scheduled to launch some time in 2014.
