>And here we are, not even a full year after Gabe's talk, and the first post-touch products are already landing on Planet Earth: Glass, Myo, Leap Motion, Kinect, on and on.
I don't think these devices/interfaces are really any better than touch with respect to "do what I really mean". It's still hand eye coordination at the level of our limbs and motor senses.
I think real "do what I really mean" post-touch interfaces are the ones where our minds become the actuators, instead of our limbs. Things like translating neural signals to actions. We just got the first Telepathic Mice , you know?
