But at the headquarters of London startup FundamentalVR, I got to try out what might be the surgical training tool of the future. It uses cheap virtual reality components combined with haptic feedback to give doctors as realistic a training experience as current tech will allow. Wearing an HTC Vive headset and wielding a pair of pen-shaped 3D manipulators, I sawed off a knee bone and bored holes in the spine of an unprotesting virtual patient. And while I don’t quite feel confident enough to don scrubs and head to the nearest OR, the simulation felt to me like much more than a novelty. It felt like a learning experience.
