1. A method for analyzing positions on a touch sensitive device, executed by a microprocessor from a non-transitory computer readable storage medium, comprising:

  • detecting, by a plurality of sensors, sensing information including a corresponding plurality of signal values and differential values including a plurality of zero-crossings, wherein each zero-crossing is between a positive differential value first then a negative differential value, or between a negative differential value first then a positive differential value;

    determining, by a controller, the number of a plurality of positions based on the plurality of signal values; and

    determining, by the controller, coordinates for each of the positions according to the signal values only when the number of the plurality of positions is smaller than the number of the plurality of zero-crossings.
