Ivan Sutherland - HMD (Head-Mounted Display)


Nel 1968 Ivan Sutherland (scienziato e informatico statunitense, pioniere di internet, vincitore del Premio Turing nel 1988) e il suo assistente Bob Sproull creano il primo sistema di realtà virtuale con visore. Era primitivo e il visore era così pesante da dover essere appeso al soffitto, per questo venne chiamato "La Spada di Damocle".

«We live in a physical world whose properties we have come to know well through long familiarity. We sense an involvement with this physical world which gives us the ability to predict its properties well. For example, we can predict where objects will fall, how well-known shapes look from other angles, and how much force is required to push objects against friction. We lack corresponding familiarity with the forces on charged particles, forces in nonuniform fields, the effects of nonprojective geometric transformations, and high-intertia, low-friction motion. A display connected to a digital computer gives us a chance to gain familiarity with concepts not realizable in the physical world. It is a looking glass into a mathematical wonderland.»
