Head-Mounted Displays

Definition

Head-mounted displays (HMDs) are wearable devices that place visual displays in front of the eyes, creating immersive environments for the user. These devices are often used in virtual reality (VR) and augmented reality (AR) applications, allowing users to experience interactive simulations, 3D environments, and enhanced visual content that can transform how information is presented and consumed.
