A woman pleaded not guilty on Tuesday to what is believed to be the first traffic citation alleging a motorist was using Google’s computer-in-an-eyeglass. The device, known as Google Glass, features a thumbnail-size transparent display above the right eye.

The technology will not be made widely available to the public until 2014, but defendant Cecilia Abadie was one of about 10,000 “explorers” who received the glasses earlier this year as part of a tryout.

Ms. Abadie was pulled over in October on suspicion of going 129 kmph in a 105-kmph zone on a San Diego freeway. A California policeman tacked on a citation usually given to people driving while a video or TV screen is on. Ms. Abadie, a software developer and tech true believer, pleaded not guilty to both charges.
