The Sword of Damocles is widely considered to be the first virtual reality (VR) and augmented reality (AR) head-mounted display (HMD) system. It was created in 1968 by hall of fame computer scientist Ivan Sutherland with the help of his student Bob Sproull. Before he began working toward what he termed "the ultimate display", Ivan Sutherland was already well respected for his accomplishments in computer graphics (see Sketchpad). At MIT’s Lincoln Laboratory beginning in 1966, Sutherland and his colleagues performed what is widely believed to be the first experiments with head-mounted displays of different kinds.
