They are also in our skin, distributed across the surface of our bones, within our spines, and definitely a bunch of it is up in our heads.
Designers, magicians, and filmmakers tap into many aspects of this construction process to great effect. Our eyes can differentiate hundreds of frames per second, but we can extrapolate continuous movements at much lower speeds, which allows us to enjoy stop-motion animation and animated gifs. Many graphical user interfaces, or GUIs, use the metaphor of the desktop as a way to organize information (see Figure 2-1). This relies on a process known as assimilation, our ability to reuse mental models across new types of information. We have already learned how a physical desk works; this existing mental model helps us to understand how to use a computer’s operating system more easily. Another perceptual phenomenon, known as ...
