Virtual reality (VR) is a computer-generated simulation of an environment or experience that immerses users in a three-dimensional, interactive world. It's designed to stimulate the senses, creating an artificial environment that can be explored and interacted with as if it were real. VR typically involves the use of a headset also called Head Mounted Displays (HMD) or goggles that display a virtual environment to the user, often coupled with specialized controllers, sensors, gloves or controllers to enable interaction within that environment. This technology has applications in gaming, education, training, healthcare, and various other industries, offering immersive and often highly engaging experiences.
