Google Glass, the futuristic technology that's in the hands and on the heads of some developers and journalists, was the topic of discussion at Google's I/O conference Thursday, but was also on the minds of members of Congress who sent a letter to the search giant seeking answers about how it plans to "incorporate privacy protections into the device."
The letter, signed by eight members of the Bi-Partisan Privacy Caucus, including caucus co-chairman Joe Barton, R-Texas, was directed to Google co-founder Larry Page, with a request for responses to questions by June 14.
Among those questions: Will Glass be able to use facial recognition technology "to unveil personal information about whomever and even some inanimate objects that the user is viewing?" If the company is collecting "device-specific information (such as your hardware model, operating system version, unique device identifiers and mobile network information including phone number)" will Glass also collect data "about the user without the user's knowledge and consent? If so, why? If not, please explain."

While Google Glass is very much in its infancy, its recent limited release has already raised concerns among Las Vegas casinos and movie theaters.
NBC News asked Google for comment about the congressional letter. Steve Lee, director of product management at Google Glass, released a short, emailed statement.
"We've consistently said that we won't add new face recognition features to our services unless we have strong privacy protections in place," Lee said.
