Abstract:
1. A waveform dividing method for a capacitive touch control device, comprising steps of: step A: saving and updating a first waveform in a direction caused by a first object when the first object touches the capacitive touch control device; step B: saving a multi-touch waveform in the direction when the first object is stationary on the capacitive touch control device and a second object further touches the capacitive touch control device, wherein the multi-touch waveform is established by the first waveform and a second waveform in the direction caused by the second object; step C: identifying whether the multi-touch waveform has waveform overlapping resulted from the first waveform and the second waveform; and step D: extracting the second waveform from a difference between the multi-touch waveform and the first waveform if the multi-touch waveform is identified as having waveform overlapping; wherein step C further comprises a step of identifying the multi-touch waveform as having waveform overlapping when the multi-touch waveform does not have a valley.
