Have you seen the video of a woman standing in front of an smart mirror trying on clothes, interacting with the system using hand gestures? For example, see Oak Labs at http://www.oaklabs.is/. The Wayfair online furniture store uses AR to help you visualize new furniture in your home before you purchase (https://www.wayfair.com). In Chapter 8, Room Decoration with AR, we will build a little app that will let you decorate your room with framed photos.
