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.
As for all those mistakes I make - they are on purpose - to teach you how to deal with them.
A big ethical question is what happens after people stop using the device. Does it degrade the environment? Could it have been designed so it would actually be good for the environment?
Beauty and brains, pleasure and usability - they should go hand in hand.
User-centered design means working with your users all throughout the project.
We expert teachers know that motivation and emotional impact are what matter.
In my opinion, no single design is apt to be optimal for everyone.
