Whatever Happened to “Augmenting Human Intellect”?
Presented by Scott Murray November 20 2013
Exploring the fundamental role of data visualization in a palatable form to human perception
Murray does an excellent job outlining Doug Engelbart’s seminal work, really nails the essence of his vision with great visuals (of course), and discusses how it might inform or inspire the field of data visualization. He also covers the contributions of Vannevar Bush and Charles Babbage.
