How VR works ?
Virtual Reality works by using a combination of hardware and software to create an immersive experience for the user. The most basic component of a VR system is a headset, which typically consists of a screen or screens in front of the eyes, and sensors that track the user’s head movements. Some VR systems also include hand-held controllers, allowing the user to interact with the virtual environment.
The VR headset displays a 3D virtual world, which is generated by a computer and typically viewed through specialized lenses that produce a stereoscopic image. The headset’s sensors track the user’s head movements, allowing them to look around the virtual environment, and the VR software adjusts the displayed image accordingly. Some VR systems also track the user’s hand movements, allowing them to interact with the virtual environment.
When the user wears the VR headset and interacts with the virtual environment, their brain is tricked into believing that they are actually in that environment, creating a sense of presence. This sense of presence is enhanced by using additional technologies, such as haptic feedback, to provide physical sensations that correspond to actions in the virtual environment.
