Early Experiments w/ Computers

Recreational Technology/Hobby Culture Spacewar! (1961) First fully implemented computer game MIT Model Railroad Club/Steve "Slug" Russell DEC Digital PDP-1

“Medium” for Creation "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." – Ivan Sutherland Sketchpad (1963) Ivan Sutherland’s Ph.D. Thesis First “computer graphics” application Allowed you to draw directly on the screen with a stylus

Virtual Reality "The ultimate display would, of course, be a room within which the computer can control the existence of matter. 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 room would be fatal. With appropriate programming such a display could literally be the Wonderland into which Alice walked.” —Ivan Sutherland Head-Mounted Display, Ivan Sutherland (1969-1970) First “virtual reality” system <video>
