A touch positioning method, wherein the method comprises: recording first track information about moving of a contact point formed by the contact of a user's finger on a capacitive touch screen, the first track information comprising a contact range at each sampling time point when the contact point moves on the touchscreen; determining, from the first track information, second track information that is before a process in which the contact point leaves the touchscreen; and positioning, according to the second track information, a position at which the contact point leaves the touch screen wherein determining, from the first track information, second track information further comprises: discarding track information within a determined time period corresponding to a process in which the contact point leaves the touch screen; wherein the determining, from the first track information, second track information that is before a process in which the contact point leaves the touch screen specifically is: determining the time period as a time period during which the contact range continuously changes in a process in which the contact point leaves the touchscreen and using a contact range of the contact point at a sampling time point that is immediately before the time period as the second track information that is before the process in which the contact point leaves the touchscreen; and the positioning, according to the second track information, a position at which the contact point leaves the touch screen specifically is: calculating a position according to the contact range of the contact point at the sampling time point that is immediately before the time period, and determining the position obtained by calculation as the position at which the contact point leaves the touchscreen. recording first track information about moving of a contact point formed by the contact of a user's finger on a capacitive touch screen, the first track information comprising a contact range at each sampling time point when the contact point moves on the touchscreen;
