Remember when virtual reality was hailed as the next groundbreaking technology for both the mobile and PC industry? Even though it might feel like an eternity, it actually wasn’t that long ago when Samsung unveiled the first edition of its Gear VR headset to pretty great fanfare, while Google tried its hand at something similar with the Cardboard and Daydream platforms.

That big guy’s fourth shooter is a “DepthVision” or time-of-flight sensor that uses advanced AR technology to perform real-time measurements of objects and spaces located in the phone’s field of view. Meanwhile, Samsung also sells a so-called “mixed reality” headset for $500, which doesn’t need to be paired with a smartphone or computer to work its magic. That might explain why the significantly cheaper but also rudimentary Gear VR, which is practically useless by itself, is quietly and unceremoniously going away.
