Where The Controls Are

A decision for designers is not just which controls to have, but where to put them: on, near, or remote.

One of the central tasks of any device designer is to create the interaction model. The interaction model is the overarching framework that ties the functionality together into a unified whole.

Every button, slider, switch, knob, or dial represents a choice. Two choices, actually: the choice to have it, and the choice to use it.
