😲 VR goggles were first tested in 1968, when computer scientist Ivan Sutherland and his student Bob Sproull created the Sword of Damocles, the earliest head-mounted display. It was a primitive system that showed simple wireframe graphics and tracked head movement in real time, but it was so heavy it had to be suspended from the ceiling. Despite its limitations, this experiment laid the foundation for modern virtual reality by proving immersive, head-tracked digital environments were possible. (🎥: pintarte.nava.mx) #surprise
