What Will Replace Computer Keyboards?

Computer keyboards will be phased out over the next 20 years, and we should think carefully about what replaces them as the dominant mode of communicating with machines, argues Android co-founder Rich Miner. Virtual reality technology and brain-computer links -- whose advocates include Elon Musk -- could lead to a "dystopian" future where people live their lives inside of goggles, or they jack directly into computers and become completely "de-personalized," Miner worries.

He takes a more "humanistic" view of the future of human-machine interfaces, one that frees us to be more expressive and requires computers to communicate on our level, not the other way around. That means software that can understand our speech, facial expressions, gestures, and handwriting. These technologies already exist, but have a lot of room for improvement.

One example he gives is holding up your hand to pause a video.
