Wearable “retina” display taking to another level!

I can still remember the first encounter with 3D wearable displays more than 13-14 years ago. The bulkiness together with the low frame rate meant they were not entirely comfortable to use, and the novelty soon wore off because of lack of applications. Now, more than a decade later, there is the Google Glass (introduced last year) which can be made relatively cheaply – for always-connected situations – and perhaps a onslaught of more sophisticated displays for heavy media (as in high-quality cinema) consumption!?
