The usecase I always envisioned was an all-in-one replacement for multi-monitor setup, TV, and essentially all visual media. I also imagined the flexibility to operate a computer in bright sunlight or while laying in bed thanks to a the goggles being sealed and replacing your vision. This is surely only a matter of the technology improving a bit. I believe a redesign of periphals suited to the ergonomics of VR would be required for my particular vision to be achieved. I suppose what I'm talking about is just a HMD but it could be optionally combined with head tracking like the implementations that exist now. I recall many years ago that HMDs where available so theyre nothing new. Why didnt they take off? Too clunky? Unpleasant somehow?
