“In 1988, Apple Computer produced some video scenarios showing how future computers would be able to understand hand gestures, read text, and respond to voice commands. Almost 20 years later, the world is still waiting for a natural way of using computers—though we are beginning to see some of our wildest dreams slowly emerge from the chaos of high technology and become real. In 2006, it is easy to believe that the masses will soon be able to use a computer without any keyboard or mouse. Beyond the constrained space of our personal computer’s monitor, keyboard, and mouse, I’m looking for the sort of revolution that would overtake the wild dream of Blade Runner. I can envision huge 3D virtual worlds and systems that are smart enough to feel a user’s mood and respond intelligently. Now, where do you want to go today?” (Leandro Agrò – UXmatters)
