Hacking the inner ear to fake the feelings of movement in video games?
|Virtual reality, as it exists now, works because humans trust their eyes above all else. And in a VR headset, the possibilities of what you can see are pretty much infinite. What you can feel, on the other hand, is not. But what if virtual reality, as it might exist in the future, also fools the inner ear that keeps track of motion? That’s where galvanic vestibular stimulation comes in. Put an electrode behind each ear, hook up a 9 volt battery, and you can stimulate the nerves that run from your inner ears to the brain. Zap with GVS and your head suddenly feels like it’s rolling to the right. Reverse the electrodes and you feel your head roll to the left. The vestibular system keeps you situated in space by relying on the subtle movements of fluid and tiny bones in your ears. To find out more of this technology, click the link: http://www.wired.com/|
