Ivan Sutherland – the Albert Einstein of interactivity – created SKETCHPAD, the first application that let users ‘draw’ onto a computer display. Five years later he followed that up with his ‘ultimate display’ – inventing virtual and augmented reality with a device nicknamed the SWORD OF DAMOCLES.
A video from Lincoln Labs, demonstrating some of the features of Ivan Sutherland’s SKETCHPAD, the first program that allowed you to draw to a computer display of an interactive computer, the TX-2:
And here’s the PDF of his 1965 paper: Sutherland – The Ultimate Display
By 1968, Sutherland was ready to show his ultimate display at the Fall Joint Computing Conference in San Francisco. Here’s what his ‘Sword of Damocles’ looked like in operation:
The proceedings for the 1968 Fall Joint Computer Conference paint the picture of computing at its pivot from arcane to mainstream, growing into greater interactivity. Here’s the stellar list of papers – featuring two by Sutherland, both foundational to VR and 3D graphics: FJCC Proceedings
