Amazon Seeks 1-Nod Ordering Patent

theodp writes "Amazon.com is famous for its patented 1-Click ordering system. But what about 1-Nod ordering? Amazon CEO Jeff Bezos is seeking a patent on a system that would let people make purchases with a nod, a smile, or even a raise of the eyebrow. Bezos' invention — 'Movement Recognition as Input Mechanism' — envisions a computing device that could interpret certain facial expressions and enhance or potentially replace conventional input devices such as keypads and touch screens."
