Abstract

A method for counting according to movement of an object includes the following steps, sensing movement of the object, transferring the movement of the object into a corresponding sensing signal, and when the sensing signal includes a first waveform including a first relative extreme value and two neighboring relative extreme values and a second waveform including a second relative extreme value and two neighboring relative extreme values, wherein the difference between one of the two neighboring relative extreme values with the first relative extreme value or the second relative extreme value, is less than a predetermined value, and the first waveform and the second waveform will combined with other ungrouped waveforms to determine whether a count value should be updated, according to the updated count value of the first waveform and the second waveform.
