The three burner gas stovetop in Fig.
1 and the five burner electric stovetop in Fig.
2 are quite different than the original single-burner
single-control conceptual model. However, the multiple controls
can be easily mapped to their burners. The associations in WM between
the controls and the burners are strong. It is likely after viewing
either stovetop once, users would be able to sketch an accurate
Structured design, that is, the
grouping of multiple components into a single coherent model, is a
powerful design strategy, that not only facilitates usability and
increased accuracy, but also memorability.

to their burners.

electric burners can be easily mapped
to their controls.
