Abstract:
1. A touch input control method for an electronic device with a touch screen and a storage unit storing a calibration database, the method comprising: displaying an interface comprising a plurality of objects, each object associated with predetermined touch coordinates; generating signals in response to a touch on the touch screen which is an attempt to touch an object; calculating coordinates of the actual touched portion on the touch screen according to the generated signals; determining whether the coordinates of the touch match the predetermined touch coordinates of one of the objects displayed on the touch screen; creating an adjustment signal if the coordinates of the touch do not match the predetermined touch coordinates of any of the objects; determining which finger it is which does the actual touching according to the shape of the touched area, the size of the touched area, and the touch calibration data of a user's commonly used finger, recorded in the calibration database, wherein the size of the touched area is calculated according to the shape of the touched area, the resolution of the touch screen, and the size of the touch screen; retrieving a touch offset direction and touch offset distance of the determined finger of the user from the calibration database; and compensating the coordinates of the touch of the user according to the retrieved touch offset direction and the retrieved touch offset distance of the determined finger, so as to determine the object which the user intended to touch.
