Abstract
Techniques are presented for detection of a false touch on a touchscreen. The method includes recognizing a multi-touch instruction sequence, determining whether the multi-touch instruction sequence includes at least a first touch component corresponding to a predicted false touch, and in response to determining there is a false touch, disabling multi-touch functionality for the multi-touch instruction sequence.
