Abstract: A touch control module and a tracking method for touch point and a touch sensitive electronic device are provided. The device includes a multi-touch touch panel and the touch control module. The module performs the tracking method including the following steps. N first touch points and M candidate points are acquired respectively in a first and a second detecting period. When any one of the candidate points falls within a pairing extent of any one of the first touch point, the control module pairs the candidate point with the first touch point. The detecting perimeter is a function of a minimum detecting value and a distance-between-finger value. K paired candidate points are assigned as K second touch points. A maximum interval distance among the K pairs is retrieved, and the pairing extent can be adjusted according to the maximum interval distance.

Abstract: A method for identifying a contact with a touch panel includes: performing a first measuring process for obtaining a baseline signal; performing a second measuring process for obtaining a contact signal if there are any contacts or approaches of the touch panel with objects; comparing the values of the baseline signal with the contact signal for generating the contact signal with a location information; performing a third measuring process for installing an exclusion area according to the baseline signal; determining whether the location information is in the exclusion area; and, discarding the location information if the location information is in the exclusion area.
