Being Digital Quotes

“I was involved in building an early prototype of a machine that pushed back at you, a force-feedback device in which the effort required to move it could be a function of anything you wanted. Under computer control, it could change from moving freely to feeling as if it were being pushed through molasses. In one application, we had a map of Massachusetts with a demographic database. The user could plot plans for a new highway by moving this force-feedback digitizer. However, the amount of force needed to push it varied as a function of the number of families that would be displaced. In fact, you could close your eyes and plot out very literally the path of least resistance to a new highway.”
― Nicholas Negroponte, Being Digital
