I've been looking at the iPod- the Apple iPod. One of the interesting things about the iPod, one of the things that people love most about it is not the technology; it's the box it comes in

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

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.

Too many companies believe that all they must do is provide a 'neat' technology or some 'cool' product or, sometimes, just good, solid engineering. Nope. All of those are desirable (and solid engineering is a must), but there is much more to a successful product than that: understanding how the product is to be used, design, engineering, positioning, marketing, branding-all matter. It requires designing the Total User Experience.

In the university, professors make up artificial problems. In the real world, the problems do not come in nice, neat packages. They have to be discovered.

To me, error analysis is the sweet spot for improvement.

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
