Apple may not be nearly as enamored with virtual reality as Facebook, Google orSamsung, but that doesn't mean it's uninterested -- it's clearer than ever that Cupertino has been intrigued for years. The USPTO has granted Apple a patent(originally filed way back in 2008) for a headset design that uses your iPhone as a virtual reality display. The basic concept bears more than a small resemblance to Samsung's Gear VR. You slot your phone into a cradle that sits in front of your eyes, and an external controller (in this case, a remote) helps you navigate when motion tracking isn't enough.
