I'm not a fan of technology . I'm a fan of pedagogy, of understanding how people learn and the most effective learning methods. But technology enables some exciting changes.

It is relatively easy to design for the perfect cases, when everything goes right, or when all the information required is available in proper format

Attractive things work better.

When a device as simple as a door has to come with an instruction manual—even a one-word manual—then it is a failure, poorly designed.

Scientists are always skeptics.

What makes something simple or complex? It's not the number of dials or controls or how many features it has: It is whether the person using the device has a good conceptual model of how it operates.

Beauty and brains, pleasure and usability - they should go hand in hand.
