In line with the Visual Turing Test enlightenment, this VR display research is driven by Mark Zuckerberg’s vision for the future of VR. To fulfill the promise of the metaverse that he shared last Fall, there is the need to deliver visual experiences that are almost indistinguishable from reality.
Today’s VR headsets deliver incredible 3D visual experiences, but the experience still differs in many ways from what we see in the real world.
They have a lower resolution than what’s offered by laptops, TVs and phones; the lenses distort the wearer’s view; and they cannot be used for extended periods of time.
To get there, we need to build an unprecedented type of VR display system — a lightweight display that is so advanced it can deliver what our eyes need to function naturally so they perceive we are looking at the real world in VR. This is known as the “Visual Turing Test” and passing it is considered the holy grail of display research.
To pass the visual Turing test, the Display Systems Research (DSR) team at Reality Labs Research (RL Research) is building a new tech stack that includes:
- “Varifocal” technology that ensures the focus is correct and enables clear and comfortable vision within arm’s length for extended periods of time
- Distortion correction to help address optical aberrations, like warping and color fringes, introduced by viewing optics
- Resolution that approaches or exceeds 20/20 or 6/6 human vision
- High dynamic range (HDR) technology that expands the range of color, brightness, and contrast in VR
DSR is also developing prototypes that explore the headset form factor and how to reduce the size, weight, and power of existing VR headsets as much as possible to make room for these visual elements.
