Virtual reality is the creation of a fictional or simulated environment or scenario that looks completely real and that allows us to move to any place or situation we want as if we believe ourselves inside it, with the illusion of being inside this environment. Through a device such as virtual reality glasses or helmets, we can immerse ourselves in games where we create our characters or travel around the world without leaving the sofa in the living room, but through a realistic experience. In addition, it allows the use of other devices... For example, you can use headphones or simulated laser swords.
