Can you visit a website without clicking? It's not easy. If you don't believe me, check it out.
Alex Frank's dontclick.it site demonstrates a mouse less user interface. The site requires Flash (you'll quickly see why this is so).
You are allowed one click to start off the interface, and from then on as you use the mouse to grok the interface, you are warned not to click.
If you do so, " you will get this type of screen on your desktop"
It is highly strange to navigate for an extended period without clicking.
Mouse-clicking has always seemed so primitive. We are like prehistoric creatures that can only simple point at something and bark. It will be interesting to see how long it will take for the next breakthrough. Until then we are left with the gillette approach of “add more blades”, but in our world it means more buttons and wheels on a mouse.
