This is neat, but, well, have you ever tried working out with something strapped to your face? Worn big goggles while doing something that works up a sweat? First you fog up, then you notice the saturated sponge flolloping (as only a mattress truly can) against your face as you cycle.<p>I had a &quot;VR&quot; cycling setup about 15 years ago for training in the winters in Durham (cobbled roads, snow, not so great on tubeless rims) - comprised my road bike, a standard rear wheel roller with a resistance adjustment cable attached to my handle bars, and most importantly an SVGA projector hooked up to the ceiling to project on the blank wall four feet ahead of me, keystoned to hell and back to not end up too distorted.<p>On the projector I&#x27;d chuck up a POV cycling vid, either one that I&#x27;d shot with a camcorder strapped to my head the previous summer (oh what I would have done for a gopro), or a professional one. Manually adjust the resistance according to what you see on the screen (easy enough, just get to the point that you&#x27;re matching pace with the head-bob on the video), job done.<p>Surprisingly immersive setup for a pile of late 90&#x27;s electronics.
