  • Have you ever tried VR? Did you ever feel a little sick? Maybe it’s not all in your

  • head, maybe it’s in your chromosomes.

  • Hey guys Julia here for DNews

  • Virtual Reality is racing full steam ahead into being one of the fastest growing areas

  • of future entertainment. I’ve tried it. Full headset with goggles and headphones.

  • I found it kind of fun, but it’s still a ways off from revolutionizing the world. One

  • main challenge is that men seem to have a better experience with it than women.

  • Before we get to that let’s take a look at how VR works in the brain.

  • One study published in the journal Nature Neuroscience found that the brain treats the

  • space in VR as different from the real world. Neurophysicist from UCLA were originally searching

  • for clues on Alzheimer's, specifically in regards to the hippocampus. A part of the

  • brain that deals with memory but also with spacial awareness and creating a mental map

  • of the environment.

  • In the study they tracked the neuron activity of rats as they entered a room and then as

  • they entered the same room but only on a VR system. They were studying to see if the brain

  • would respond the same way with both rooms, even though the VR room wouldn’t have smell

  • or sound. The researchers found that the brain responded very differently depending on the

  • situation.

  • When the rats were in the VR room their neurons fired randomly, suggesting they had no idea

  • where they were in space. And what’s more interesting, half the neurons that fired in

  • the real room were fired in the VR room. It was like half of their neurons were shut down

  • in the fake space.

  • So maybe there’s something missing from VR with our other senses. The researchers

  • think we take in clues from sounds and smells to figure out where we are in real space.

  • But headphones easily fix the sound problem, but other problems are a little tricker to

  • solve.

  • VR is also missing virtual movement, our inner sense called theta-phase precession, and our

  • sense of where our body parts are, which is called proprioception. But some companies

  • are working on this, like the Virtuix Omni, which is treadmill to walk on as you use the

  • Oculus Rift. Youre attached to this harness and almost buckled into this cage so you won’t

  • fall off. Writer Raymond Wong compared it to a baby walker.

  • And VR is missing things from its visual systems too, something that could lead to gender bias

  • in VR.

  • Basically there’s two ways your eyes perceive things like depth. Motion parallax, is when

  • something is moving towards you it gets bigger in your perception. And shape-from-shading,

  • when you move around an object your eye picks up on subtle clues from shadows. As you move

  • around the object, the shadows change. But your eye does this by flickering just ever

  • so slightly.

  • But sex hormones act on the eye, strongly. So men and women literally see things differently.

  • Women tend to rely on shape from shading to judge depth and dimension, men seem to rely

  • on motion parallax.

  • VR, while it’s made great strides in the past decade, still isn't the greatest when

  • it comes to shape from shading. According to Danah Boyd Principal Researcher at Microsoft

  • Research and the founder of Data & Society Research Institute, computers are terrible

  • at simulating that tiny, constant flickering of your eyes. So VR systems mostly rely on

  • motion parallax. What does that mean? Well Boyd suggests it could be a possible reason

  • so many women get sick from VR. A system that makes half the world’s population sick,

  • still needs more research. But it’s definitely something to look forward to in the future.

  • Just like all the cool innovations Intel is working on!

  • Intel creates the breakthrough technologies that make amazing experiences possible. Having

  • Intel inside makes for better experiences outside. Intel drives innovation with products

  • like processors, wearables and IOT devices, and within data centers. In the PC and beyond.

  • While VR gets better every year, one thing it seems to be getting really good at is virtual

  • sex! Check out this video from our friends over at Seeker:

  • So what improvements do you want to see from VR? Have you tried it? Tell us about it in
