1. A method of controlling a handheld electronic device, comprising:
- determining using a capacitive touchscreen display a location of a touch input on a touch-sensitive input surface of the capacitive touchscreen display;
determining one or more characteristics of a motion signal generated corresponding to a motion of the handheld electronic device by an accelerometer in response to an external force applied to the touch-sensitive input surface of the capacitive touchscreen display which generates the touch input, wherein the one or more characteristics of the motion signal are associated with the external force applied to the touch-sensitive input surface of the capacitive touchscreen display which generates the touch input;
comparing the one or more characteristics of the motion signal to predetermined thresholds to determine whether the motion signal corresponds to a normal tap or hard tap;
selecting an input from at least two inputs associated with the location of the touch input in accordance with whether the motion signal corresponds to a normal tap or hard tap; and
generating the input selected from the at least two inputs associated with the location of the touch input, wherein the generation of the input selected is dependent on the motion signal and touch the input being detected within a predetermined duration of each other.

16. A handheld electronic device, comprising:
-
a controller; a capacitive touchscreen display coupled to the controller and having a touch-sensitive input surface which generates a touch input signal in response to detection of an external force being applied to the touch-sensitive input surface, wherein the touch input signal has one or more characteristics representing at least a location on the touch-sensitive input surface at which the external force was detected; and a motion detection subsystem comprising an accelerometer which is coupled to the controller which generates a motion signal corresponding to motion of the handheld electronic device in response to an external force applied to the touch-sensitive input surface of the capacitive touchscreen display which generates the touch input signal; the controller being configured to; determine using the capacitive touchscreen display a location of the touch input on a touch-sensitive input surface of the capacitive touchscreen display; determine one or more characteristics of the motion signal generated by the accelerometer in response to an external force applied to the touch-sensitive input surface of the capacitive touchscreen display which generates the touch input signal wherein the one or more characteristics of the motion signal are associated with the external force applied to the touch-sensitive input surface of the capacitive touchscreen display which generates the touch input signal; compare the one or more characteristics of the motion signal to predetermined thresholds to determine whether the motion signal logically corresponds to a normal tap or hard tap; select an input from at least two inputs associated with the location of the touch input in accordance with whether the motion signal logically corresponds to a normal tap or hard tap; and generate the input selected from the at least two inputs associated with the location of the touch input, wherein the generation of the input selected is dependent on the motion signal and the touch input signal being detected within a predetermined duration of each other. - View Dependent Claims (17, 18, 19, 20)
