Characteristic information of size of continuous contact area etc., it will be understood that this feature information can also be other characteristic informations,
The disclosure to not limiting in this respect.
Then, judge whether the characteristic information of the shape of the continuous contact area meets preparatory condition, for example, it is assumed that should
Characteristic information is the characteristic information of shape, judges the shape and the similarity of default reference figuration of the continuous contact area and is
It is no to be less than or equal to predetermined threshold value, if less than or equal to predetermined threshold value, then illustrate to meet preparatory condition.Again for example, false
If this feature information is the characteristic information of size, judge the size of the continuous contact area and default size difference whether
Less than or equal to predetermined threshold value, if less than or equal to predetermined threshold value, then illustrate to meet preparatory condition.If this continuously connects
The characteristic information for touching region meets preparatory condition, then the continuous contact area can be defined as into effective contact area.
It is appreciated that effective contact area of the finger on screen, the disclosure pair can also be determined by another way
Do not limited in terms of the concrete mode for determining effective contact area of the finger on screen.
In step 503, the positional information of effective contact area is obtained.
