Apple has taken a big step into augmented reality by acquiring Metaio, a German company whose technology has been used by Macy's, BMW and furniture retailer, Ikea.
Augmented reality systems add information to a user's view of the world to help them do things like work, shop or drive. Whereas virtual reality makes it look like you're in a different place, AR allows you to be more informed about your actual surroundings.
BMW has demonstrated glasses that display navigation data and other travel information, and link up with cameras on the outside of a car, to let a driver see "through" the vehicle for tasks like parking. A startup called Augment offers software for iOS and Android that lets users visualize 3D renderings within the space in front of them, for jobs like designing store displays.
AR might prove to be the next step in user interfaces, an area where Apple has often led the way. Some of its biggest rivals have already started to explore the area. Google Glass, now being redesigned for consumers but still available for business, gave AR a high profile and suffered the consequences in the form of the initial public reaction. Microsoft has a lot riding on its HoloLens concept, which has no shipping date yet but is tied into the company's next OS, Windows 10.
Asked about media reports of the Metaio acquisition, Apple didn't confirm or deny it. "Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans," the company said in an email message.
