It Bounced! The Dog-Ears Principle.
“It bounced!” That’s what my two year old nephew said when I was showing him photos on my iPhone. I taught him how to flip through the photos. Then he got to the last photo. He tried to flip past that photo. It didn’t just refuse to move. It bounced. & it was enough for a two year old to recognize how cool this was.
I was reminded of Kathy Sierra’s presentation at SXSW. 20 Ways to Woo your Users. She had used this very example (minus my nephew) to describe the dog-ears principle. You know when a dog is surprised, & it’s ears perk up? That. Is what. You want your customers to feel.
