The wireless one-size-fits-all OASIS visor was slightly larger than a pair of sunglasses. It used harmless low-powered lasers to draw the stunningly real environment of the OASIS right onto its wearer’s retinas, completely immersing their entire field of vision in the online world. The visor was light-years ahead of the clunky virtual-reality goggles available prior to that time, and it represented a paradigm shift in virtual-reality technology—as did the lightweight OASIS haptic gloves, which allowed users to directly control the hands of their avatar and to interact with their simulated environment as if they were actually inside it. When you picked up objects, opened doors, or operated vehicles, the haptic gloves made you feel these nonexistent objects and surfaces as if they were really right there in front of you. The gloves let you, as the television ads put it, "reach in and touch the OASIS." Working together, the visor and the gloves made entering the OASIS an experience unlike anything else available, and once people got a taste of it, there was no going back.
