Neil has posted a video of Don Norman (most famous for his book The Design of Everyday Things) speaking at the Business of Software conference last year in San Francisco.

“Imagine you’re on the first slide of your powerpoint presentation and want to move to the next slide. Your remote control has two buttons. They are unmarked, but one button points up and one button points down.

“Which button do you press?”

It turns out half the people press up, half the people press down, and everybody thinks their choice is obvious. It’s a great talk.

The early bird discount for the Business of Software 2010 (Boston, October 4-6) saves you $400, but it expires this week, so this is the right time to sign up for my favorite conference.
