I don't even know what to call this;, what the correct buzzword is (if there is one) -- gestural computing? It is the notion that one can control computers with subtle body actions --

EMBEDDED TECH BRINGS A NEW LANGUAGE OF INTERACTION

The new language will be ultra subtle and totally intuitive, building not on crude body movements but on subtle expressions and micro-gestures. This is akin to the computer mouse and the screen. The Mac interface would never have worked if you needed to move the mouse the same distance as it moved on the screen. It would have been annoying andCopyright Fjord deeply unergonomic. This is the same for the gestural interface. Why swipe your arm when you can just rub your fingers together. What could be more natural than staring at something to select it, nodding to approve something? This is the world that will be possible when we have hundreds of tiny sensors mapping every movement, outside and within our bodies. For privacy, you’ll be able to use imperceptible movements, or even hidden ones such as flicking your tongue across your teeth.

This article by Fjord's Andy Goodman and Marco Righetto in Fast Company's Co.DESIGN introduces the vision at the tail end of a brief review of computer interface models, including

the punch card (1953)
Rand's tablet and pen interface (1961) Copyright Fjord
Apple's and Xerox's first graphical interfaces (c. 1984)
the first mass-market touchscreen (2007's iPhone)
Microsoft's Kinect (2009)
no-interface interface's (Siri and Google)

Why The Human Body Will Be The Next Computer Interface

FJORD CHARTS THE MAJOR INNOVATIONS OF THE PAST, AND PREDICTS A FUTURE OF TOTALLY INTUITIVE "MICRO GESTURES AND EXPRESSIONS" THAT WILL CONTROL OUR DEVICES.

The Disappearing Interface

MARCH 4, 2013 AT 6:30 AM PT

Where static computer screens and smartphones suck in our gaze and extract us from the world around us, many of the most interesting new tech gadgets and ideas move us back out into the open.

Instead of all-purpose, full-focus devices, these new tools are migrating outward, on and around our bodies, to our fingers and heads and wrists and ears, and even feet. From there, they can be ready to help us the moment we need them, in a manner that’s less abstracted and hard to talk about without referencing science fiction.
This isn’t a new phenomenon, but it’s becoming more and more accessible and interesting. You might glue together a bunch of these ideas by thinking of them as the disappearance of the interface.
