Abstract
A method and device for determining a single touch or multiple touches is disclosed. A touch related sensing information with a single zero-crossing is used for determining a pair of values, and the locations of a pair of centroids are calculated depending on the pair of values. The distance between the locations of the pair of centroids can be used to determine whether the number of touches is one or more.
Claims21
A method for determining a touch or touches, comprising:
- obtaining a sensing information;
- determining each touch related sensing information in the sensing information;
- and
- analyzing each touch related sensing information having a single zero-crossing to determine whether each touch related sensing information having a single zero-crossing indicates a touch or touches.
A device for determining a touch or touches, comprising a controller or a host for performing the following operations:
- obtaining a sensing information;
- determining each touch related sensing information in the sensing information;
- and
- analyzing each touch related sensing information having a single zero-crossing to determine whether each touch related sensing information having a single zero-crossing indicates a touch or touches.
