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.

Abstract
The method and device for analyzing position are disclosed. By analyzing sensing information with at least one zero-crossing, each position can be analyzed. The number of analyzed positions may be different from the number of zero-crossings. When the number of analyzed positions is different from the number of zero-crossing, the number of analyzed positions is more than one.
