Sitting here in Australia writing my news, I'm tethered to my smartphone because my 4G access is faster than my 8Mbps home Internet connection. I know what lag is, but do you? Well, Swedish broadband provider, Ume.net, has used Oculus VR's Rift headset to display how lag would be if it were in real-life.
Ume.net used an experiement it called "Living with lag," where four volunteers went about in their daily lives using an Oculus Rift, strapped up with a Raspbeery Pi, webcam and noise-cancelling headphones. This gave the volunteers simulated lag in two parts: 0.33 seconds, or a full 3-second delay. The results are quite amusing, with the lagged out volunteers stuffing about in their normal daily lives.
