A controller samples, after determination of a start of a user's press on a pressable input surface of a pressure sensing member, a value of an output voltage of the pressure sensing member, and determines whether one of a first condition and a second condition is satisfied to accordingly determine whether the user's press on the pressable input surface is terminated. The first condition represents that the sampled value of the output voltage is lower than a predetermined second voltage threshold. The second condition represents that the output voltage has converged to a base voltage. The base voltage is a value of the output voltage of the pressure sensing member with no user's press on the pressable input surface of the pressure sensing member.
