there are plenty of ways that people try to escape the sometimes underwhelming reality of everyday life going to the movies visiting the local watering hole or just sleeping until noon but there's been a lot of buzz recently about the idea of actually immersing yourself in a virtual world with a virtual reality headset such as the oculus rift or HTC vive but even though the concept of plugging a general-purpose VR headset into a gaming PC is just starting to take off people have been sticking their heads into virtual environments for quite some time all the way back to 1962 when the world was introduced to the sensorama a contraption that not only played 3d movies but could tilt the viewer seat and even simulate wind and different odors a few years later a headset called the sword of Damocles came out man they had better names back then rift vive I want a sword of Damocles the name was because it was so heavy though that it had to be suspended from the ceiling although it could only display simple wireframe graphics it was considered the first true VR headset virtual reality in video games didn't really start appearing until the 1980s when we started seeing arcade games like battlezone that used a periscope viewfinder to immerse players in the action and 3d glasses that were available for consoles like the Sega Master System 1995 brought us the Nintendo Virtual Boy the first mass marketed VR console but although that one was marketed as being a totally immersive experience its underwhelming monochrome graphics and difficulty of use made it one of the worst flops in Nintendo history however other companies were working on PC compatible headsets during this time and the evolution of technology over the years ultimately gave us the hi-spec VR headsets of today but then how do they work modern VR headsets show slightly different images to each of your eyes to fool your brain into thinking the 2d image on the screen is actually 3d this principle is called stereoscopy and is actually similar to how the screen on a Nintendo 3ds works to achieve a higher level of immersion VR headsets use special lenses to increase the users field of view as well as pixels with very quick response times to reduce motion blur meaning OLED screens have become popular for headsets which you can learn more about here by the way unlike a monitor which can deliver a perfectly enjoyable gaming experience at 60 frames per second headsets have higher refresh rates typically around 90 Hertz and the high quality ones today which is important because lower frame rates lower refresh rates can be disorienting in a VR context and cause motion sickness not what you want after you've dropped several hundred bucks on a rift or a vibe because though of the high frame rate requirement and the headset resolutions that are well beyond 1080p a high-end PC system is basically a necessity but beyond just graphics VR headsets have sensors like gyroscopes and accelerometers to allow for head tracking so that what you see will change depending on where you're looking some headsets like the HTC vive even use separate external base stations and lasers to enable whole room tracking so the system can detect the motion of your hands as well so as you can imagine these headsets don't exactly come cheap fortunately other lower-cost VR solutions are becoming increasingly popular such as Google cardboard which isn't much more than a couple of lenses inside a cardboard box with a slot where you can insert a smartphone developers have already written quite a few apps for cardboard making it a way to enjoy VR on the cheap if you don't have the coin for a gaming rig and a fancier headset and although this new generation of VR headsets is just now hitting the market there's already quite a bit of industry support meaning that VR has the potential to really make up how we experience games on both PCs and consoles maybe one day we'll even have VR tech quickie I
