Sony recently unveiled Project Morpheus, its own attempt at creating a virtual reality headset.
At a preview event in London, BBC technology correspondent Rory Cellan-Jones tried out one of the demo games, and found it a rather uncomfortable experience.
He also spoke to Dave Ranyard, director of Sony's UK-based games studio, about the product.
