Google on Tuesday adviced early adopters of its Internet-connected eyewear not to be "Glassholes." The suggestion was posted online for software developers and others taking part in an Explorer program providing early access to Google Glass.

Glass connects to the Internet using Wi-Fi hot spots or by being wirelessly tethered to mobile phones. Pictures or video are may be shared through the Google Plus social network.

Google is concerned over the camera capabilities built into Glass, which could be disturbing for other people in public places such as restauraants or pubs.

Don't be "creepy or rude (aka, a "Glasshole")," Google said in a guide posted online for Explorer program members.

"Respect others and if they have questions about Glass don't get snappy."

"If you're asked to turn your phone off, turn Glass off as well," Google said.

"Breaking the rules or being rude will not get businesses excited about Glass and will ruin it for other Explorers."

Google also advised early adopters not to stare into the inset prism screen for long periods at a time.
