Google wants to change the world – but do we want to be changed?

There has rarely been a single item of technology that has caught public interest as much as the launch of the Apple iPhone did in 2007. Google's wearable technology Project Glass is now looking to capture that same interest.
By overlaying information into a heads-up display, users can access an Android OS while going about their day. A new promotional video shows happy Californians skydiving, enjoying ballet and flying lessons, all the time being augmented by hands-free image and video capture.
Fifteen million views in its first week on YouTube show that the Google augmented reality glasses have overtaken the iWatch as the most coveted piece of wearable technology that you can't own yet. There has also been an influx of ideas on social media sites speculating around possible uses for the kit. But will Project Glass be a commercial success?
