In my lecture on user interface engineering I start out with a short history of human computer interaction. I like to discuss ideas and inventions in the context of the people who did it, besides others I take about Vannevar Bush and his vision of information processing , Ivan Sutherland's sketchpad , Doug Engelbart's CSCW demo (including the mouse) , and Alan Kay's vision of the Dynabook .
One aspect of looking at the history is to better understand the future of interaction with computers. One typical question I ask in class is "what is the ultimate user interface" and typical answers are "direct interface to my brain - the computer will do what I think" and "mouse and keyboard" - both answers showing some insight…
As the mouse is still a very import input device (and probably for some time to come) there is a recent paper that I find really interesting. It looks at how the mouse could be enhanced - Nicolas Villar and his colleagues put really a lot of ideas together . The paper is worthwhile to read - but if you don't have time at least watch it on youtube.
