VRFocus - It’s astonishingly clever, really. A virtual reality (VR) head-mounted display (HMD) that does away with expensive PC hardware and utilises the smartphone, something that almost everyone has in their pocket, as a display, processor and head-tracker. Of course the experience isn’t comparable to what you’ll find on the Oculus Rift, but as a low-end introduction to the most exciting upcoming technology, it’s a brilliant solution requiring low cost and low horsepower.
