ELECTRONIC DEVICE AND TOUCH INPUT CONTROL METHOD THEREOF
First Claim
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 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 the user'"'"'s commonly used finger, recorded in the calibration database, and retrieving the touch offset direction and the 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.

Abstract
A touch input control method comprising steps is provided: displaying an interface comprising at least one object; gathering signals as to actual touches for calibration purposes. In use, calculating coordinates of the touch; determining whether the coordinates of the actual touch match the predetermined touch coordinates of the object; creating an adjustment signal if the coordinates of the touch is not the same as the predetermined touch coordinates of any object; determining which finger used for touch input, and retrieving a touch offset direction and a touch offset distance of the determined finger of the user from a calibration database; and applying compensation to the coordinates of the touch, so as to determine the touched object. An electronic device using the touch input control method is also provided.
