Abstract
A touch sensitive keypad device () for an electronic device () includes one or more keys () situated in a keypad carrier (). One or more conductive layers () span the keys. One or more transverse conductive layers () are integrated with a non-key component, such as the keypad carrier (). A capacitance sensing circuit () detects changes in capacitance between the conductive layers and the transverse conductive layers to detect user input, thereby allowing a user () to use a matrix () of keys as a touch pad.
