Virtual reality has unlimited potential, but it could make you sick. Stanford researchers are trying to solve that problem by tapping another new tech, light-field cameras. You see, VR devices can cause fatigue and nausea because of the “flat plane” 3D images they produce. Since those images don’t contain any depth information, your eyes can’t focus on near and far objects like you would in real life. Our brains want physical actions (like focusing) to jibe with what we see, so any disconnect can make us sick. And if companies can’t solve this “VR sickness,” the tech may go the way of 3D TVs.
The Stanford team found a clever way to make your eyes focus inside its device. Using the same principal as a “light-field” camera like the Lytro, but in reverse, they built a headset that has transparent LCD panels stacked in layers, which each layer representing a light field with the correct depth information.
