Ergonomy : Finger and hand world by Microsoft

Microsoft imagins the future of IT

It's full of hand & finger commands... well. How long people will like moving their arms, their fingers with quite "big" gestures to command devices, or computers ?
It's fun, it's "minority report" style, but is it an sustainable way of life.

Typing on a keyorad or on phone keys and clicking with a mouse is effortless, tactile screens, tactile phone, tactile fridge, tactile table, tactile screen, is so boring and so tiring !

Command with our brain activity, or voice, with slight finger movement or head movement, that's real progress ! ... because it's simply more efficient than typing on a keyboard or clicking with a mouse.
