mask Oculus Rift can experience a virtual reality.
VR glasses Oculus Rift from Oculus VR nominated several times for the best product on the gadget CES in Las Vegas. In the new prototype used a trick to reduce the risk of motion sickness.
mask Oculus Rift have two monitors placed in front of the eyes which makes it possible to experience a virtual reality when one is wearing the mask.
So far it is not to buy, but the attention surrounding the mask is great, and the new prototype Crystal Cove that was shown at CES gadget was praised by many who tried it.
Two innovations distinguish the new prototype.
One is a system to keep track of where the user’s head is located. So far, gyro sensors on the mask could detect how the head is rotated about three axes. The picture in the screens are moved based on the turn so that the virtual reality seems to stand still for the user, even if the head is turned.
In the new prototype also recorded how the head is moved in three directions. That means, for example, can lean forward and to the side, and thus get a different view of the virtual reality, for example by sticking his head out through a window.
The new system is based on an infrared camera that detects light from the infrared LEDs on the mask.
The second innovation is a technique to reduce the risk of motion sickness when using the mask.
problem with motion sickness is partly due to a slight delay between the head is turned and that the image moves accordingly. But it also depends on a combination of movement and of the video image flashing.
An object that moves in the picture, such as a lamp on a ride-on car, does not move continuously without visible at discrete points that move with the same frequency as the frame rate – usually between 30 and 100 frames per second. When trying to follow the light with eyes will therefore feel that it is moving erratically back and forth during the movement, which can contribute to nausea.
trick used in the new prototype called “low persistance” or short duration. It means letting the pixels representing the lamp be lit only for a brief moment in every frame – at the very moment when he is in the right place in the image. The rest of the time the brain to fill in the picture as then perceived as one continuous motion.
The technology is said to reduce the risk of motion sickness significantly, but should also contribute to longer light intensity of the image.
displays are of OLED type and according Oculus VR can trick of short duration made more efficient with OLED technology than LCDs.
