I'm curious about how virtual reality experiences are created. Can you explain how our brains perceive the images thanks to sensors and screens placed in the headsets? How do they respond to head movements or hand inputs? What components are involved that aren't found in smartphones?
What is the operating principle of the Meta Quest?

Recently, I played a match in the VR game called Wave Zone with some friends. The moment I put on the headset, it felt like I was inside a completely different world. First of all, the Meta Quest 3 has two separate screens placed in front of each lens—these micro-OLED panels provide both sharpness and a sense of depth. When you put the headset on, just like your brain normally merges the images from both eyes to create depth perception, this system instantly compares images taken from different angles to give you that 3D feeling.
The most impressive part, though, was how it responded to my head movements in real time. For example, when I tilted my head slightly to hit the ball, the algorithms detected it in a tenth of a second and updated the visuals—so you get an experience that’s perfectly in sync with your movements. Hand inputs, on the other hand, rely on Inertial Measurement Unit (IMU) sensors, which analyze both accelerometer and gyroscope data. Since smartphones don’t have this level of precision, the lag in your movements during a VR experience is almost nonexistent.
