METHODS AND APPARATUS FOR DETECTING USER'S TOUCH ON A TOUCH PANEL
First Claim
1. A method for detecting a user'"'"'s touch on a touch panel, the method comprising:
- deriving a plurality of geometric differences of a first direction of the touch panel, wherein each of the geometric differences of the first direction represents a difference between respective coupling amounts at two locations of a plurality of locations of the first direction on the touch panel; and
analyzing the geometric differences of the first direction to obtain at least one analysis result, wherein the analysis result comprises information representing whether the user touches the touch panel in one or more places.
