VR has come, players look forward to but also disturbing, for fear that his dizziness can not play it, and wasted so much money. Nvidia recently GTC 2016 Conference published the VR technology, known as the complete elimination of dizziness.
We know that when the VR experience may be dizzy and sick, is seen in the eye sight and body balance system is not caused. This is not more different, Vertigo is more serious. Because of this, VR head most importantly reduce delays, refresh rate of at least 60Hz, Oculus Rift and HTC Vive 90Hz, Sony PlayStation VR is even 120Hz.
However, Nvidia announced to the people: my family's new technology can be reached 1700Hz! If you want to make a straightforward comparison--90Hz device displays an image every 11 milliseconds, per 0.58 Ms 1700Hz device can display a picture.
GTC in 2016, David Luebke, Nvidia r Vice showed off the company's latest technology prototypes. Nvidia to fix the screen on a track system allows it to quickly move back and forth. By virtue of a mainstream device 20 times times the refresh rate, display images in a strenuous exercise can still keep the amazing stability.
Luebke said, "If you can use this technique in VR Displays, this level of ultra low latency will keep things stable like a rock, when the screen will no longer cause the root causes for the delay, we think this is a zero-delay screen. "
Of course, this level of tracking accuracy of display is not enough, you also need ultra low latency input. Thus, we see the Nvidia demo track system. Luebke said of the entire system's response is almost instant, delay is very low and very precise. If there is no such entry, even so quickly the display cannot show a stable image.
Generally 20 milliseconds of delay control for VR is already very good, Nvidia soared to 1700Hz is there a point? Luebke said, when reduced latency to 10ms people feel better, even down to 1 MS, people are able to feel it.
To avoid VR Vertigo, a method not only reduce latency. HTC Vive using so-called Lighthouse Lighthouse technology allows players to have the opportunity to walk in the room, experience more immersive effect. In addition, we may also need a pair of handles to simulate their own hands. Maximise quality and reduce delays, is the basic means of enhancing the VR experience. Even Samsung has also introduced a technique to cause themselves through electrical stimulation of the player's ear is the illusion of motion. In a Word, as long as you believe you are roaming the virtual world of the brain, Vertigo is no longer an issue.
