A group called “Stop The Cyborgs” warns that Google Glass and other augmented reality gadgets risk creating a world in which privacy is impossible.

Stop The Cyborgs wants limits put on when headsets can be used.

It has produced posters so premises can warn wearers that the glasses are banned or recording is not permitted.

The campaign comes as politicians, lawyers and bloggers debate how the gadgets will change civil society.

Stop The Cyborgs warns that Google Glass and other augmented reality gadgets risk creating a world in which privacy is impossible

Based in London, the Stop The Cyborgs campaign began at the end of February and the group did not expect much to happen before the launch of Google Glass in 2014.

However, the launch coincided with a push on Twitter by Google to get people thinking about what they would do if they had a pair of the augmented reality spectacles. The camera-equipped headset suspends a small screen in front of an owner and pipes information to that display. The camera and other functions are voice controlled.

Google’s push, coupled with the announcement by the 5 Point Cafe in Seattle to pre-emptively ban users of the gadget, has generated a lot of debate and given the campaign a boost.

Posters produced by the campaign that warn people not to use Google Glass or other personal surveillance devices had been downloaded thousands of times.

In addition, coverage of the Glass project in mainstream media and on the web had swiftly turned from “amazing new gadget that will improve the world” to “the most controversial device in history”.

The limits that the Stop The Cyborg campaign wants placed on Google Glass and similar devices would involve a clear way to let people know when they are being recorded.

In a statement, Google said: “We are putting a lot of thought into how we design Glass because new technology always raises important new issues for society.”

“Our Glass Explorer program will give all of us the chance to be active participants in shaping the future of this technology, including its features and social norms,” it said.

Already some US states are looking to impose other limits on augmented reality devices. West Virginia is reportedly preparing a law that will make it illegal to use such devices while driving. Those breaking the law would face heavy fines.
