Everybody has used the GPS. The one to-go feature for all your navigating problems. Global positioning system has been successful in tracking the outdoor objects on a map(i.e. buildings, shops etc) but what about the indoors (i.e tracking inside a shop/building)
This is where VPS comes into picture. Google released concept of new technology called Visual Positioning Service,which uses augmented reality on mobile phones and tablets for navigation.
While the GPS will help you reach the door of the the shop, VPS helps you in locating the exact position of the items you want to buy from the shop.
This technology along with audio-interface is a game changer for visually impaired.
The technology is in its initial stage and still developing with not much application however once its perfected it will spread like wildfire.
