## Summary
A parallax barrier is a device placed in front of an image source to display a stereoscopic image without requiring viewers to wear 3D glasses. It works by using a physical barrier to create separate left and right eye views, allowing for a three-dimensional visual experience. This technology is classified as computer hardware and has been documented in various languages, including Japanese, Russian, and Chinese.
