VR headsets and their respective experiences can be split into two main categories: three degrees of freedom (3DoF) and six degrees of freedom (6DoF). To put it simply, 3DoF headsets allow users to turn their head left, right, up and down. 6DoF on the other hand, allows users to physically move forward, backwards, laterally and vertically. A 6DoF headset offers a far greater level of immersion to 3DoF but the practicalities and cost associated with it increases the barrier to entry for schools. The cost of a 6DoF headset is continuing to decrease and in five years, who knows, secondary schools and colleges may be running science experiments in VR. At PrimeVR, we currently use high end 3DoF headsets from our educational partner, Pico.
