Summary Rumors of an Apple-branded virtual reality (VR) or augmented reality (AR) solution have floated for years, with evidence of Apple's interest in the market continuing to surface and evolve over time. Numerous patents have been published, either created by Apple or absorbed from firms the company acquires, with ideas ranging from AR devices with to, with the additional use of an iPhone to power the technology in many cases. On the software side, Apple has launched ARKit, to help developers make AR applications for iOS devices.

Apple is believed to be working on advanced virtual reality/augmented reality systems that could be incorporated into future iOS devices and/or hardware products. There aren’t any concrete details about the products or when they might launch, but the company’s focus in the area has increased over the past several months. More recently, Apple has confirmed it is interested in augmented reality, by releasing to developers during WWDC 2017. Detailed below, ARKit is a platform that allows developers to more easily incorporate augmented reality into their apps.

Tim Cook said in that Apple is “doing a lot of things” in the AR space and has called it a “core technology.' He even hints at favoring it over VR. 'There's virtual reality and there's augmented reality — both of these are incredibly interesting,' Cook said in the interview. 'But my own view is that augmented reality is the larger of the two, probably by far.' In August, Cook said that 'I think AR is extremely interesting and sort of a core technology,' 'it's something we're doing a lot of things on behind that curtain that we talked about.' Then in October, he again touted the benefits of AR over VR: 'There's no substitute for human contact,' Cook said. 'And so you want the technology to encourage that.'

In a interview, Cook elaborated on his thoughts on AR, calling it a 'big idea' concept, like a smartphone. Cook also suggested AR holds more promise than VR, as the latter 'closes the world out' while AR keeps it all visible. 'The smartphone is for everyone, we don't have to think the iPhone is about a certain demographic, or country, or vertical market; it's for everyone. I think AR is that big, it's huge,' said Cook.
