Everyday Things

Years ago I read a cool book The Design of Everyday Things. In a modest way, it changed my life. I learned, among other things, that on doors in public places horizontal handles push out and vertical handles pull. It's hard to describe how much that simple concept has simplified my life.

Tonight I visited with a friend I haven't seen in years. She told me her daughter recently started a business in Human Factors consulting. Who knew that everyday things had become a "multidisciplinary field incorporating  psychology, engineering, industrial design" called Human Factors. And that this would lead to "World Usability Day."

I want to know more about this.
