You may have heard of augmented reality.
A technology that overlays text, images and other objects onto a view of the real world.
Here are a few easy ways to try it for yourself.
Snapchat let's you overlay special effects on your face with a front facing camera.
Press and hold on your image then swipe through for different effects.
When using the rear camera, tap the screen to activate world lenses.
Walk around them, or leave them hovering in the picture while you film.
Facebook offers similar features in its own camera.
Select from different masks or visual effects that responds to your movements.
Some Lowes stores in the US show directions and the quickest path to items on your shopping list with augmented reality.
To use it, you'll need a phone running Google's Tango technology.
If you don't have one, they're available to borrow in-store.
