A couple of days ago I got the chance to play with the HD Oculus Rift virtual reality headset, and I would have bought it then and there.
I couldn't believe how good it was - how accurately it recognised my movements, and how seamlessly it translated them into in-game actions. It's fortunate that I didn't buy it (to be honest buying it was never an option - it was kind of needed for the whole CES demo thing), because Oculus Rift has just got even better. The new version - aptly named Crystal Cove for the faceted structures that dot its chassis - takes VR to a new level.
There are a couple of changes in Crystal Cove. The first is 'Low Persistence', which all but eliminates lag and blur by switching its new, faster 1080p OLED screen's pixels on and off at high speed. Compared with the Oculus HD Prototype I tried a couple of days back, it works extremely well - I could even read the tiny text on my spacecraft's control panel in EVE Valkyrie, so clear were they - and the OLED adds the super-saturated colours we're accustomed to from the likes of the Samsung Galaxy S4.
But the more fundamental change is the inclusion of some entirely new hardware that measures not only the orientation of your head, but how it's moving in 3D space. This hardware consists of an array of LEDs dotted over the chassis of the Rift headset and a modified USB webcam of unspecified resolution to track them, and the resulting experience is astonishingly immersive.
In a specially built 3D fantasy tower defence game from Epic, it was possible to get closer to the scenery and avatars I was trying to blast by leaning over in their direction. I could look up at the roof of my dungeon, and dive into the fiery pits below. It's proof that not just FPSs and simulators can benefit from VR.
With previous generations of the Rift, rotating or tilting your head has an instant corresponding change in what you are looking at: you are a disembodied head fixed in space. The Crystal Cove hardware adds another three degrees of freedom - it sees how you lean and tilt. This gives the attached computer more positional data to work with, which makes for entirely new gaming experiences.
You can turn your head almost a full 180 without it losing your position (there are no LEDs round back at present), and if it does lose you, the screen desaturates and the standard accelerometer, gyroscope and magnetometer kick in until the camera finds you again.
