A method of synchronizing data acquisition and a portable electronic device configured to perform the same

A method of synchronizing force data with touch data comprises: receiving an interrupt signal generated by a touch-sensitive display when a change greater than a predetermined threshold occurs on a touch-sensitive overlay of the touch-sensitive display; generating a time stamp when the interrupt signal is received from the touch-sensitive display; receiving an interrupt signal generated by a force sensing transducer when a force greater than a predetermined force threshold is applied to the touch-sensitive display; generating a time stamp when the interrupt signal is received from the force sensing transducer; synchronizing touch data for a particular touch event with force data for a force event corresponding to the particular touch event; outputting the synchronized touch data and force data to input processing operations. A portable electronic device configured to perform this method is also provided.
