A head-mounted display (HMD) is a wearable device that can be worn on the head like a helmet or glasses, and it can display virtual reality (VR) or augmented reality (AR) content. An HMD typically consists of two small screens, one for each eye, that are positioned in front of the user's eyes. The screens are often embedded in a headset, which can be adjusted to fit comfortably on the user's head. HMDs can be connected to a computer, gaming console, or other device to display immersive content in a variety of applications, including gaming, education, training, and medical simulations.
HMDs can be further classified into two types: tethered and untethered. Tethered HMDs are connected to a computer or console with cables, while untethered HMDs are self-contained and do not require a separate device to operate. Untethered HMDs are often more expensive than tethered ones, but they offer greater freedom of movement and are generally more user-friendly.
In online communities focused on VR or gaming, discussions around HMDs are common. Users may share their experiences with different HMD models, offer advice on how to set up and calibrate the device, or discuss the latest features and technologies. HMDs can also be used for virtual meetups, where users can gather in a virtual space and interact with each other as if they were in the same physical location. In this context, HMDs are seen as a key tool for creating immersive and engaging online experiences.
