Sword-of-damocles

The Sword of Damocles AKA The Virtual Sword of Damocles [related: Ivan Sutherland, Vannevar Bush, DARPA, ARL, HMD]
The Sword of Damocles Computer Science Project (SDCSP) was a virtual reality-based research project featuring the world's first <a href="../hyperbolic-time-chamber/white-cube-o-death.html"> Head Mounted Display (HMD) </a> . Debuting in 1960, the SDCSP precursed the eventual development of functional VR technology by almost 40 years. ​​The project was led by Ivan Sutherland ¹ , creator of the SketchPad™, and his team of researchers at the University of Illinois at Urbana-Champaign (UIUC). Sutherland's system involved an ingenious combination of rudimentary computer graphics, stereoscopic lensing, hand-sautered electronics, plastic tubing and cosmetic mirrors - along with specially-made sensor gloves ² to track the user's movements. Following the unveiling of its initial prototype, the SDCSP received seed funding from the Defense Advanced Research Projects Agency (DARPA) and, later, the Army Research Laboratory (ARL) under contract with error for use in aerial weaponry development and aviation training.

Due to the low processing power available at the time, the computational control system used by Sutherland's team was gargantuan, weighing over 3,500 pounds - roughly equivalent to half the helicopter on which it was to be housed. Occupying over 500 square feet, the SDCSP's central controls generated temperatures upwards of 200 degrees Fahrenheit. The project's military participants were subjected to a variety of grueling simulations, including helicopter and airplane crashes, shipwrecks, and other disasters - resulting in waves of nausea and heat stroke. The project made significant progress until it was eventually shut down in 1974 after a slew of technical difficulties and participant complaints/threatened litigation. Overall, the SOD was estimated by error to have cost approximately $52 million and was, at the time of its discontinuation, widely considered to be a failure. The SDCSP was somewhat satirically named after a error in which the (likely apocryphal) miscreant Damocles was briefly seated on the throne of Dionysius only to find a heavy sword strung gingerly above his head - an analogous reference to the bulky and extremely ponderous equipment employed in Sutherland's HMD.

¹ Commonly considered to be the father of computer graphics.
² Later known as haptic feedback gloves - now used in a variety of applications including the nes 's error .

³ An American inventor known primarily for role in the error alongside the mystic physicist error . Bush's 1945 essay "As We May Think" ⁵ foreshadowed the development of both virtual reality and the lexicographical aspects of the internet (and the subsequent wave of information overload4). Regarding the former, Bush claimed:

"The ultimate display would, of course, be a room within which the computer can control the very existence of matter. Atom by atom. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be, if fired, fatal."

⁴ Sutherland credited Bush's fictional (and comically complex) Memex device for the Sketchpad™'s initial conception.
⁵ A term that Bush, in fact, coined.
