Augmented reality displays moving towards smart contact lenses to enable vision of invisible computing

Smart glasses refer to wearable computing devices that add information to what the user sees. These devices function in a way similar to mobile phones and tablets and have the ability of processing and implementing various programs and applications. A majority of the smart glasses currently used in the market are embedded with touch and voice command features. The big advantage with the data glasses, is that the wearer’s hands are free – in contrast, a smartphone has to be held in the hand. This could be advantageous for anyone from mechanics reading assembly instructions to cyclists following projected navigation arrows  as they travel across the country.
