Don Norman on NUI

Don Norman, the author of The Design of Everyday Things, Emotional Design, and The Design of Future Things among many other books and papers has written an interesting article, "Natural User Interfaces are not Natural" about gesture-based systems and Natural User Interface design.

Although nothing in the article is earth shattering - simply having him endorse and acknowledge NUI is wonderful. The main gist of the article is that gestural systems are not a panacea and that we have a long way to go before standardizing its use.
