A head-mounted display (HMD) is a device worn on the head that provides visual output directly to the user's eyes, typically incorporating a pair of small screens or optical systems. These devices are often used in virtual reality (VR) and augmented reality (AR) applications, allowing users to immerse themselves in digital environments or overlay information onto the real world. HMDs rely on advanced projection systems and microdisplays to deliver high-quality visuals while tracking head movements for an interactive experience.
