Abstract
A detection method of touch system for avoiding inadvertent touch is disclosed. The steps of the detection method includes: obtaining a plurality of first detection signals; determining whether a difference of strength between the first detection signals is less than a default difference; calculating a first centroid on the first detection signals, which if the difference of strength between the first detection signals is less than the default difference; setting a first rejection area extrapolated from the first centroid; obtaining a plurality of second detection signals for determining whether to update the first rejection area; calculating a second centroid on the second detection signals; calculating a rate of the first centroid to the second centroid; and, proceeding an update for replacing the first rejection area with a second rejection area extrapolated from the second centroid, if the rate is greater than a default value.
