Virtual Reality (VR) is an artificial environment where users can feel immersed in a three-dimensional world. Powered by sophisticated software and hardware such as headsets like the Oculus Quest, Sony PlayStation VR, Varjo VR and XR, Valve Index and HTC's Vive, VR can transport your users to entirely simulated environments that can be gamified, educational, military or training oriented, among many others.
There are two types of VR: three Degrees of Freedom and six Degrees of Freedom. Degrees of Freedom, or 'DoF', refers to how you move in a virtual environment with the use of a VR headset and additional hardware (controllers, VR gloves, processors, smartphones, etc).
- Three Degrees of Freedom: is usually limited to head movements (up and down, left to right and side to side). With three Degrees of Freedom, it’s only possible to rotate your head but not move around. Interacting with your environment is not directly possible with this type of VR. There are ways that you can simulate this – albeit in a way that isn’t entirely natural.
- Six Degrees of Freedom: is a more sophisticated version of VR and combines the rotation of the above with movement (front/back, up/down, and left/right). With six Degrees of Freedom, you can move around in any direction in a virtual space.
