Abstract
The disclosure relates to a method for recognizing touch. A first value T1 and a second value T2 are set. A maximum sensing value Cpeak is obtained. A position of the Cpeak is defined as a sensing position A. Sensing values C1, C2, C3, and C4 of four neighboring sensing positions are obtained. Cpeak is compared with T1 and T2. When Cpeak is greater than or equal to T1, a touch with finger is recognized. When Cpeak is smaller than T2, no touch is recognized. When Cpeak is greater than or equal to T and smaller than T1, following steps are taken. A third value T3 is set. A first total sensing value Ct of C1, C2, C3, and C4 is compared with T3. When Ct is greater than or equal to T3, a touch with glove is recognized. When Ct is less than T3, no touch is recognized.
