head-mounted display (HMD)
A head-mounted display (HMD) is a device worn on the head that provides visual information directly in front of your eyes. It typically consists of screens or lenses that display digital images, often used for virtual reality (VR), augmented reality (AR), or gaming. By tracking head movements, HMDs create an immersive experience, allowing users to see and interact with digital environments as if they were real. They are commonly used for entertainment, training, simulation, and professional applications, offering a personal, portable way to access computer-generated visuals without needing external monitors.
