Thus, the designer did not make explicit the purpose of each button. This design effectively maps the placement of burners to their controls, by making the relationship explicit. Further, the placement of the controls on the flat surface with the burners, rather than perpendicular to the stove, eliminates the problem of burners accidentally being turned on. In addition, instead of using push buttons to activate the burners as in the original design, I would instead use knobs. Even on top of the stove, possibility remains that something could be dropped on the surface, and inadvertently turn on a burner.
Knobs are less likely to be activated accidentally.
The combination of these functions should make the redesigned stove easier to use for novice users, and should allow for error, decreasing the likelihood that the stove could be activated inadvertently.
