The Oculus Rift: How It Works

    Taking Your Eyes to New Levels of Vision

    Establishing a focal point is critical to perceiving depth. You’re looking at a virtual image plane in each eye. In essence, the user’s eyes are staring beyond the display and into the virtual environment.

    Playing Tricks on the Eyes

    A high-resolution screen that sits just a few inches from a user’s eyes projects a stereoscopic image—or two warped images on each half of the screen. “We’re just using the normal way that humans use binocular vision to perceive depth,” Patel says. “There are horizontal offsets between objects visible in the left and right eyes, which the visual cortex can process to perceive depth.” In other words, when the warped 2-D images are viewed in close proximity, users are tricked into believing they’re standing in a virtual world.

    Using Tech to Enhance Reality

    The headset comes equipped with more than a dozen sensor inputs. For example, a gyroscope, accelerometer, and compass track the location of a user’s head. Designers also added external infrared sensors and a camera to increase positional accuracy and monitoring. Software running on a nearby host PC analyzes that data and renders images of a virtual world that adapt to head position. Luckey says that the system’s low latency enhances realism.

    Great sound to fully immerse you

    To be fully immersive, you need great sound, and Oculus has some of the most spatially accurate. “All you need is to simulate two microphones in the game, and you can simulate audio in the real world,” co-founder of Oculus VR Palmer Luckey says. But the truth is that the software is slightly more sophisticated. “We can generate a good approximation of what each ear should hear at its location in virtual space,” says Patel, “which is much better than what you could do with a typical surround-sound setup.”
