Virtual reality technology can be divided into two main categories: hardware and software.

Hardware

Hardware is responsible for generating the visual, auditory, and tactile experiences that make up the VR experience. Some of the most important pieces of hardware in a VR system include:

• Headset: designed to be worn on the head and have a screen or screens in front of the eyes that display the virtual environment. Some headsets also include built-in speakers or headphones for audio output and sensors that track the movement of the user's head and body.
• Input device: can take the form of handheld controllers, gloves, or even full-body suits that track the user's movements and allow them to interact with the virtual environment in a natural way.

Software

Software is responsible for creating and controlling the virtual environment. Some of the most common types of VR software include:

• Game engine: used to create and control the virtual environment. Game engines provide tools for designing and building 3D models, adding textures and lighting, and programming interactions between objects and the user.
• Content creation tools: allow users to create and share their own VR experiences.
• Simulation software: used in fields such as aviation and medicine to train professionals in a safe and controlled environment.
