A visitor to Mobile World Congress in Barcelona tries on a virtual-reality headset, one of a coming wave of VR devices. SAN FRANCISCO – I love watching people experience virtual reality for the first time. The cumbersome headsets exaggerate their movements as they scan left to right, and then nod up and down. And every time they look in another direction and spot something new, you can almost feel their amazement through the goggles. Lately, I feel as though I've put on a VR headset and never took it off. Because every time I turn, it seems, I spy something truly inspirational.
