Design experts say the Nintendo Wii works because it's not about technology, it's about experience. Unlike game stations confined to controllers and buttons, Nintendo's Wii lets people play a game like they might in the real world. A person playing tennis, for example, would swing their arm with Wii, or bowling, he or she would motion with an under-arm curl.

"It's a welcome sigh of relief to many people. Mind you this didn't take any technological breakthrough, it just took some imagination and some thought about the average person," said Don Norman, professor of design at Northwestern University.
