Finnish start-up Varjo has developed a prototype virtual reality (VR) headset that its makers claim gives an image 50 times sharper than most other headsets currently on the market. When I tested the prototype – looking round the virtual cockpit of a passenger plane – the level of detail in the small central area of vision was certainly impressive – as close to the real thing as I’ve come across.

Image quality outside this area, simulating standard VR headsets, was noticeably fuzzier.

Founder and chief executive Urho Konttori says the firm has managed to achieve this by mimicking how the eye sees.

“The human eye only focuses on a thumbnail-sized area of vision – the brain fills in the rest,” he says. “Our peripheral vision is less detailed, at a much lower resolution.”

So Varjo’s headset provides very high definition images only of the objects our eyes are focusing on at any particular moment, the rest of the scene is at lower resolution. It uses eye-tracking technology to tell which parts of the image it needs to render in high definition.
