Floor Display

My new idea for the navigation interface is to have the display of the directions and whatnot on the floor. As in arrows pointing you to where you need to go and giving you information in real-time. Of course I don't expect that people will be bending down to the ground to input their destination and other details, so it shall be linked together with a phone application which you use to input the variables, and then once you have set it up you can just put your phone back in your pocket. This solves a problem which many of us have nowadays in that we have to keep our eyes on our phone map apps in order to keep track of where we are.
