Find Your Class with Augmented Reality
Augmented Reality brings a computer program to real life; when done well, the program fills in what's missing from the real world.

Video games take advantage too, Pokemon Go took over the summer of 2016 allowing the player to see the monsters pop up all over their neighborhood through their phone's camera.
Even the NFL takes advantage of software by drawing lines over live footage to further illustrate what is happening in the plays.
I don't know where I would be if it wasn't for map applications that highlight which route to take while traveling.
