Abstract
A method for multi-touch control and associated apparatus is provided. The method includes indentifying two peak sensing values from a plurality of sensing values of a touch panel, providing a threshold according to intrinsic characteristics of the touch panel and features of the sensing values, comparing whether the sensing values between the two peak sensing values are lower than the threshold, and selectively reporting multi-touch events.
Claims20
A multi-touch control method, comprising:
- sensing a plurality of sensing values associated with a touch panel;
- providing a threshold;
- identifying two peak sensing values from the plurality of sensing values;
- comparing the sensing values located between the two peak sensing values with the threshold to generate a comparison result;
- and
- selectively reporting a multi-touch event according to the comparison result.
