A double sided screen is a projection screen that can display images on both sides, creating an immersive and interactive experience for the viewers. This type of screen can be used to create a virtual reality or augmented reality environment, where the viewers can see different scenes or objects on each side of the screen, or interact with the projected images using gestures or voice commands. A double sided screen can also be used to create a holographic effect, where the viewers can see a three-dimensional image that appears to float in the air.
