ABSTRACT:
A method for measuring a velocity of a conductor pressing on a capacitive sensor. The method includes: sampling a capacitance of a sensing electrode at each preset time; providing a threshold value; and determining the velocity of the conductor pressing on the capacitive sensor according to a specific period, wherein the specific period is defined as a period of time ranging from the time when the capacitance reaches the threshold value to the time when the capacitance reaches a peak value.
