Finally, a functional use for augmented reality. This year's IKEA catalog lets you see what furniture from the Swedish retailer would look like when it's placed in your home. The feature lets you scan a page in the IKEA catalog with a special app, or browse the catalog on your mobile device. Then, place the magazine where you want to place the furniture, and choose a product. An image will appear that will show just how great that table, chair, or sofa would look in that particular corner.
Last year's catalog also had an AR function, but the feature only let you scan pages to unlock content. Not every single piece in the catalog has the feature -- perhaps that's for next year.
