How the glass in Google Glass works

18th April 2013

On Tuesday, the first Google Glasses began arriving to the lucky early adopters, but it has now been revealed that Google has enforced restrictions on those new owners, banning them from reselling and lending the eyewear.

Google’s official terms of sale:

“You may not resell, loan, transfer or give your Device to any other person. If you resell, loan, transfer or give your device to any other person without Google’s authorization, Google reserves the right to deactivate the Device, and neither you nor the unauthorized person using the Device will be entitled to any refund, product support or product warranty.”

Back in February, a Google Glass listing appeared on eBay, with a starting price of $1,500 (the original cost from Google). That number eventually rose to $16,000 before eBay removed the listing for violating its “presale listings policy.”

Glass owners who don’t want their device have up to 30 days from delivery to cancel their purchase, according to the terms. Google asks that returns include original packaging and accessories, and remain in “reasonable” condition.

How the glass in Google Glass works

How does Google Glass work? Why can you see with it in focus? How does the image overlay your vision? The following infographic illustrates the optical principle thanks to Martin Missfeldt.

“The core feature of Google Glass is a visual layer that is placed over the reality (“augmented reality”). This layer opens a door to amazing new possibilities. But how does it work? In the Google Glass contains a mini-projector, which projected the layer via a clever, semi-transparent prism directly on the retina in the eye. Because of this the image, even though it is so close to the eye, is sharp and clear. You can move the front part of the Google Glass easily to optimize the focus.”

Google Glass App Developers

As app developers, we’re conditioned to visualise the potential of developing software for new and exciting platforms. In the build up to the launch of Google Glass, it’s possible that the focus of discussion will shift from how amazing the technology is, towards the potential concerns surrounding privacy.
