While reporting and researching the topic, the question I kept asking was what it will take to get everyday consumers to use hand gestures to control their PCs and TVs and whatever other devices they'll use. All the experts seem to agree it's inevitable, but some kind of breakthrough will need to happen to persuade people to ditch the mouse, TV remote and keyboard. Will it be quality of gesture recognition? Simplification of the product? Enhancements to user interface that accommodate gestures? Price?"
