What is there to commercialize? Imagine an application in emergency medicine whereby a person with minimum training in first aid can suddenly perform major emergency surgery on someone in the middle of nowhere, or a surgical procedure and process available but unknown to a physician in a third world country are suddenly visibly rendered in real time and space as he makes the incision, possibly encounters complications and then provided solutions, is fed the patient's vital signs, and all done with less staff and training than typically required--and without the physician ever having once before seen or performed the procedure.
Or, imagine an airplane being landed, after pilots have become incapacitated, by someone who has never flown a plane and needs more than an air controller's audible instructions to safely do so. There are indeed problems which need this solution. In fact, I'm certain we can't even imagine most of them at this point in time--just as Tom Watson (IBM) once thought the world would never need more than a handful of computers.
(And as for form factor, could Edison ever have imagined his cylinder phonograph with its huge horn now being no larger than Apple's iPod shuffle, and with infinitely better quality in every respect? Advice: Neither underestimate the future nor believe it won't be here sooner than you think.)
