Here’s a demo that illustrates my ideas on computer human interaction. Instead of controlling the movement of a 3D globe through the mouse and keyboard, why not move your head to look around the globe. You’ll need a webcam for this demo to work.

Side to side motion works pretty well. Up and down is a little iffy.

Moving around to see what’s on the other side is a much more natural and intuitive human behavior than say pressing some computer keys to change perspective of an object. I believe that as computers become more powerful and more and more people have to interact with them in their daily lives, computer scientists will have to design systems and software that provide a more natural user interface (nui) than what we currently have.

Although many people today deal with computers and the internet, this highly technical tool is still completely inaccessible to a large population because it is so difficult to use. By creating interfaces that are more natural to use, we make technology more approachable to the masses. That’s my 2 cents. Feel free to chime in.
