ABSTRACT:
A system for positional determination includes an array of piezoelectric sensor electrodes connected to an array of output lines via resistors for providing a binary code in response to activation of the sensor electrodes; and an array of further output lines also connected to the array of sensor electrodes via resistors for providing a binary error code in response to activation of the sensor electrodes. By combining the resultant binary code and binary error code, an accurate determination of the position along the array of activation of the sensor electrodes may be achieved.
