What is 'virtual reality'?

Virtual reality is best understood as a simulated 3D environment that enables users to immerse themselves in a digital setting that can mimic real-world experiences or create entirely new worlds. This technology usually employs headsets and motion tracking devices to give users the sense of being physically present in that environment, allowing them to interact with it in a way that feels tangible.

The definition emphasizes the immersive and interactive nature of virtual reality, distinguishing it from mere video conferencing, which connects users through video and audio but does not provide an immersive experience. Unlike computer hardware, which refers to the physical devices used to run software, or graphic design software, which is primarily used for creating visual content, virtual reality specifically relates to the creation and experience of simulated environments that can evoke a range of sensory experiences.
