A woman who was driving while wearing Google's new computer-in-glasses device has been cleared of wrongdoing by a court in California.
The San Diego traffic court threw out a citation against Cecilia Abadie, with commissioner John Blair ruling she was not guilty because the offence for which was ticketed requires proof the device was in use.
Ms Abadie, who was also found not guilty of speeding, is believed to be the first motorist cited for wearing Google Glass while driving.
The software developer said she was among around 30,000 "explorers" selected to try out Google Glass before the technology becomes widely available to the public later this year.
The device, on a kind of glasses frame, features a thumbnail-size transparent display above the right eye.
The lightweight frames are equipped with a hidden camera and tiny display that responds to voice commands. The technology can be used to do things such as check email, learn background about something the wearer is looking at, or to get driving directions.
Three states – Delaware, New Jersey and West Virginia – have introduced bills that would ban driving with Google Glass.
Google's website contains an advisory for users: "Read up and follow the law. Above all, even when you're following the law, don't hurt yourself or others by failing to pay attention to the road."
Ms Abadie was stopped on a San Diego freeway in October.
Her lawyer William Concidine said previously the device was not activated when she was driving.
