Google has issued advice for people testing its Google Glass smart glasses
The company announced the device in 2012. The glasses respond to touch or commands from a user's voice, displaying information on the lens. They are also equipped with a camera for stills and video recording.
The guidelines are targeted at Google's 'Explorers' - the small group of people in the USA who are testing the $1500 device ahead of an expected wider worldwide launch later in 2014.
Google says the list would help answer "new questions" arising from people wearing Google Glass in public.
'Ask for permission'
"Don’t read War and Peace on Glass", Google advises users.
"Things like that are better done on bigger screens"
'Don't be creepy and rude'
'Don't rock Glass while doing high-impact sports'
A traffic court dismissed the citation against the 44-year-old on the grounds of a lack of proof that it couldn't be proved that device was turned on while she was driving.
