Abstract
An electronic device, which may be handheld, is provided with a touch sensor and display screen. The display screen may be on a front surface of the device, and the touch sensor may be on a rear surface. Virtual keyboard key contact areas are responsive to user touch inputs, without providing any visual indicia on the display screen indicative of the positions associated with the key contact areas. Key contact area positions can be dynamically adjusted in response to locations on the touch sensitive input surface of user touch inputs.
