Facebook is developing a virtual-reality prototype headset, referred to internally as Half Dome, that could advance VR technology past some of its key frustrations, like tunnel-vision field of view and not being able to read something you hold right in front of your (virtual) face. 

Facebook executive Maria Fernandez Guajardo, who is head of Core Tech product managment at Oculus, introduced Half Dome, which looks a little like an Oculus Rift with miniaturized Frankenstein's monster bolts all over it, and other VR advancements in a presentation at F8, Facebook's developer conference and opportunity to announce major initiatives.
