iPhone and the Dog Ears User Experience Model

The fluidity and follow through of the iPhone UI ...

"I was at the Steve Jobs keynote. And like everyone else in that room, I was thrilled by the iPhone demo. The UI is spectacular, but for reasons you can't see in a photograph, or get from the online keynote video. The best part of the iPhone is simply this: the UI is alive. By implementing one of the key principles of animation, the designers have shown us the stunning power of using Dog Ears as a user experience model.

In the real world, we have physics. We have inertia. Things bounce and stretch and squash. We have follow through. Imagine a dog with long floppy ears sprinting for a frisbee. Now picture the dog coming to a screeching halt in front of the disc. What happens to the ears? They keep going. Then they "bounce" back. And it's a big part of what separates a good animator from an amateur.

Even if you don't notice it consciously, an animation (even of just words) feels more appealing and alive when things move in the virtual world more like things do in the real world (or even more exaggerated). It feels more lyrical, fluid... less abrupt. And that is what the iPhone UI does."    (Continued via Creating Passionate Users)    [Usability Resources]
