Earlier this year, Oculus VR brought to CES an improved version of its virtual reality headset, the Oculus Rift. While previous prototypes let gamers turn and look around within a virtual world in 360 degrees, the new version added a camera that let them reposition their heads, too — which meant looking down cliffs, peering around corners and leaning in to inspect small details more closely. Now that same functionality will be out in the wild, albeit in a second “developer kit” rather than a full consumer version. The kit, which opens for preorders Wednesday, costs $350 and is estimated to ship in July. At a demo area on Tuesday, Oculus representatives encouraged press to start by trying the first development kit — “Feel how blurry it is?” I heard one rep saying to a reporter — before trying the new kit. And it is a noticeable difference: The second kit, called DK2, has a higher-resolution display and less latency than its predecessor.
