Abstract: A force touch judgement method is applied to a force touch pad with two force sensors. Firstly, a force touch operation corresponding to a real force value is performed on a force touch position. Then, a first sensing signal value and a second sensing signal value corresponding to the force touch operation are respectively generated by the two force sensors. Then, the first sensing signal value and the second sensing signal value are added as a total sensing signal value. A calibration force value corresponding to the force touch position is obtained. A first calibration signal value and a second calibration signal value corresponding to the force touch position are added as a total calibration signal value. A ratio of the total sensing signal value to the total calibration signal value is equal to a ratio of the real force value to the calibration force value.

Abstract: A method for calibrating sensed force of a touch pad module is provided. The touch pad module includes a touch pad and force sensing elements disposed therebeneath. The method includes: obtaining a force reference table obtained before the touch pad module is assembled with an electronic device, the force reference table including a first data, which includes a first point of the touch pad and first force reference values corresponding to the first point and respectively corresponding to the force sensing elements; placing a calibration block on the first point after the touch pad module is assembled with the electronic device, so the force sensing elements respectively obtain first force test values corresponding to the first point; calculating first compensation ratios according to the first force reference values and the first force test values; and inputting the first compensation ratios into the force reference table.

Abstract: A touchpad module includes a base plate, a touch member, plural supporting elements, plural pressure sensing units and a feedback generation element. The base plate includes a plate body and plural elastic arms. The plural elastic arms are formed on the plate body. The plural supporting elements are arranged between the base plate and the touch member, and aligned with the corresponding elastic arms. While the touch member is moved toward the base plate, the plural supporting elements are move downwardly with the touch member to press the corresponding elastic arms. Consequently, the plural elastic arms are subjected to deformation. If the deformation amount of at least one of the plural elastic arms reaches a threshold value, the corresponding pressure sensing unit issues a pressure sensing signal. The feedback generation element generates a haptics feedback effect in response to the pressure sensing signal.
