When you buy something online, do you often have a bad sense of how big it is?
OSA helps you "see" the real size of the things before you actually buy them.
put an one-dollar bill on the table, use this APP , aim at it closely. If succeeded, you will see a 3D gift box on the screen, just like there is a real gift box on the table.
now you can adjust the length, width, height of the gift box, the gift box will scale to the size you want, then you can feel the size of things you want to buy online.
enjoy and have fun~
