Augmented Reality wayfinding system

I am wanting to develop an LCD touch-screen wayfinding system for a mall that incorporates augmented reality somewhat like this: <[login to view URL]> Client walks into the mall and approaches the wayfinding LCD touchscreen. They select a store from the list by touching the screen which then generates a float-box type enlargement of the business name and logo or photo of the business as well as a QR code to a link to download an augmented reality app to their SmartPhone which when launched, directs them to the store much like the link to the you tube video illustrates above. The marketing director of the mall would need another app to set waypoints of the locations of any participating stores.
