Disclosed is an electric range which provides specific functions without user intervention. The electric range adjusts the heating power if a user enacts a gesture that slides an item to be heated in a first direction. Also, the electric range provides additional functions if a user enacts a gesture that slides an item to be heated in a second direction.

An inductive cooktop includes a transparent panel that supports a cookware object. An electrically actuated panel, such as a display panel, is disposed below the transparent panel. The electrically actuated panel includes two sets of lines, such as data and scan lines, disposed orthogonal to each other to form a two-dimensional matrix that is configured to operate associated elements with an addressing scheme.
