Though VR environments can be theoretically limitless, real-world space is very limited, so VR researchers have developed the 'Unlimited Corridor' as a potential solution. The system, developed by a Japanese team, only requires a seven-meter by five-meter space to convince VR users that they are walking across infinitely long distances.

Other researchers' attempts to tackle the space illusion problem in VR have had major flaws. For instance, one strategy has users spin around several times once they reach the limits of their physical environment, tricking them into thinking they are still walking in the same direction after spinning. This method caused VR sickness and headaches.

In the Unlimited Corridor, users gently touch a curved wall while walking in a circle. The circle is just gradual enough that on the VR headset they believe they are walking straight.

The visuo-haptic technology behind the Unlimited Corridor could be used to create exceptionally immersive gaming environments.
