Miming is an art form in which the performer uses gestures to convey a story; charades is a game of gestures. Mimed gestures might generally be used to refer to an action in context, for example turning a pretend crank to ask someone to lower a car side window (or for modern power windows, pointing down or miming pressing a button).
The basic design of how graphics are represented in PDF is very similar to that of PostScript, except for the use of transparency, which was added in PDF 1.4. PDF graphics use a device-independent Cartesian coordinate system to describe the surface of a page. A PDF page description can use a matrix to scale, rotate, or skew graphical
SixthSense is a gesture-based wearable computer system developed at MIT Media Lab by Steve Mann in 1994 and 1997 (headworn gestural interface), and 1998 (neckworn version), and further developed by Pranav Mistry (also at MIT Media Lab), in 2009, both of whom developed both hardware and software for both headworn and neckworn versions of it.
Additionally, when people use gestures, there is a certain shared background knowledge. Different cultures use similar gestures when talking about a specific action such as how we gesture the idea of drinking out of a cup.
