The U.S. cinema associations have updated their anti-theft policy to include wearables such as Google Glass and smartwatches.

The Motion Picture Association of America (MPAA) and the National Association of Theatre Owners (NATO) have updated their anti-theft policies that restrict the use of any recording device while featuring movies inside the halls. The updated policy also adds wearables such as Google Glass and smartwatches to the restricted category, which has zero tolerance against violation.

The MPAA and NATO did not specifically name Google Glass in the list of restricted devices but mentioned wearables at large, which includes not only the controversial Glass but also smartwatches and any possible future tech devices in this category.

"As part of our continued efforts to ensure movies are not recorded in theaters, however, we maintain a zero-tolerance policy toward using any recording device while movies are being shown," according to MPAA and NATO's joint press release on Wednesday. "As has been our long-standing policy, all phones must be silenced and other recording devices, including wearable devices, must be turned off and put away at show time."

At any instance where individuals fail or refuse to abide by the updated privacy law inside the movie theaters, they will be asked to leave. Also, the management will report any illicit recording activities to the cops for further legal proceedings. Google has previously urged its Explorers, a title given to the owners of the Glass, to abide by the law of any place and taught how not to be a "glass-hole."

This isn't the first time Google Glass has been blocked from theaters. In July, Alamo Drafthouse banned Google Glass from all of its theaters. Earlier this year, a man in Ohio was pulled out of a running movie and interrogated for watching the feature with his Glass on.
