IKEA is one of the first companies to make a real world applicable use case for it. Using IKEA Place you can put on an AR headset like Hololens, or even just load it to your smartphone. Take a second to do a full scan of the room so the AR device understands the dimensions, then load up a 3D rendering of the furniture you’re interested in. You can see how the color, style, and sizing matches. When you find the item you like you can click to buy. How’s that for time saving?
