Schmidt admitted that talking to someone who is wearing Google Glass can be a bit, well, awkward, and that the wearable technology will require a new set of social rules.
Throughout history, new technologies have forced society to adapt, requiring new social norms and sometimes very big changes in the way the world operates. Out with the old and in with the new: here are a few technologies that seemed very, very strange when they were first introduced.
The answering machine
The electric toothbrush
The contact lens
Early glass models were thick and could only be worn for a few hours a day. Glass lenses eventually became smaller and lighter, but it wasn't until 1971 when Otto Wichterle invented the soft contact lens that they became commonplace.
Now, not only are contact lenses widely used for correcting vision, we are just steps away from digitized contacts that are themselves a heads-up augmented reality.
