Abstract

A method for controlling an application program, an electronic device thereof, and a recording medium thereof are provided. In the present method, when detecting at least one touch area on a touch screen of the electronic device, all touch points contained within each of the touch areas are obtained. Then, a unique typical coordinate value is determined according to a coordinate value of each of the touch points. Finally, an application program is controlled to execute a function relative to the typical coordinate value. Hence, the application program is controlled to execute the corresponding function by detecting the user operation on the touch screen so as to improve a convenience of operating the electronic device.
