You go into a large multi-level parking garage, and would like to know where are the free spaces.
Each car entering is given a reusable parking card with dual functionality: use it to pay and exit, and it will show you on a map (a small screen) currently where you can find empty spaces to park, and where you are. It’s a live map guiding you to the available spaces.
For the merchant, it’s a way to help the buyer design the space he is buying for, while choosing from their offered products. The buyer gets multiple smart designs for his space.
An app or website where you can input the measurements of the space you are trying to design, and get design suggestions complete with shopping list.
