The HTC Vive, Sony's PlayStation VR, Facebook's Oculus 'Rift' and Samsung's 'Rink' headset will be seen in the market in the next few months, BBC reported on Saturday.

Virtual reality is a computer-simulated reality (in a device) that replicates, via photos, an environment that simulates a physical presence in places in the real or an imagined world, allowing the user to interact in that world.
Virtual reality artificially creates sensory experiences which can include sight, hearing, touch and smell. For example, with a VR device you can climb Mount Everest making your way gingerly across a shaky bridge while trying not to look down into an icy chasm, all while sitting on a couch in your house.       

The devices may be showcased at the International Consumer Electronics Show (CES) that will be held from January 6 to 9 in Las Vegas. The HTC Vive is seen as the device providing the best VR experience.
