Abstract

A method for providing haptic feedback at a portable electronic device including a touch-sensitive display and a physical keyboard comprising depressible keys and touch sensors for detecting touches thereon, is provided. In response to detecting a first touch on the physical keyboard, which physical keyboard is moveable relative to the touch-sensitive display, between a first position in which the physical keyboard is exposed for use and a second position in which the physical keyboard is not exposed, wherein the first touch is associated with haptic feedback, first haptic feedback is provided to the physical keyboard. In response to detecting a second touch on the touch-sensitive display when the physical keyboard is in the second position in which the physical keyboard is not exposed, wherein the second touch is associated with haptic feedback, second haptic feedback is provided to the touch-sensitive display.
