A light-field display is a screen or projection system that sends slightly different light rays to different viewing angles. Instead of showing one flat image to everyone, it controls direction as well as color and brightness, so the viewer’s eyes receive depth cues similar to those in the real world. That makes the image appear three-dimensional without requiring special glasses in some designs.
In cyber security, light-field displays matter because they can change how people judge what is real on-screen. They are used in AR/VR prototypes, simulation, and remote inspection tools, where accurate depth perception can help operators spot defects or understand a scene. The same realism can also be abused in visual deception: an attacker could use highly convincing 3D imagery to mislead a user, hide details, or support social engineering. Defenders evaluate these systems for display calibration, user confusion, and the reliability of human verification tasks.
