Cool Facts
Special goggles. Virtual reality uses a 3D head-mounted display (fancy goggles you wear on your head) that shows different images to each eye, making your brain think you're looking at a real three-dimensional world.
Your moves matter. These VR systems track your head position and body movements so when you look around or reach out your hand, the virtual world responds just like real life would.
Feels totally real. Because VR uses 3D images and tracks your movements, your brain gets fooled into feeling like you're actually inside the computer-created world, not just watching a screen.
Many amazing uses. People use virtual reality for entertainment (playing games), education (learning in a pretend lab), research (scientists testing ideas), and business (practicing jobs before doing them for real).
Growing super fast. Virtual reality technology keeps getting better and cheaper every year, so more and more people will be able to use it in the future.
