Can use method commonly used in the prior art to confirm the centre of form of said random figure.Situation after the centre of form of said random figure and the centre of form of said test pattern overlap is shown in Fig. 4 (b).
S206 calculates the misalignment that the centre of form overlaps said random figure in back and said test pattern.When said misalignment is within the preset range, execution in step S207; At said misalignment during greater than preset range, execution in step S209.Particularly, the method for definite said misalignment comprises among the step S206:
S2061 confirms that the centre of form overlaps the second area outside the profile that first area and said test pattern outside the profile that the said random figure in back is positioned at said test pattern be positioned at said random figure.
In Fig. 4 (b), first area that said random figure (polygon) is positioned at outside the profile of said test pattern (circle) uses mesh lines to represent, the second area that said test pattern is positioned at outside the profile of said random figure uses hacures to represent.Calculate respectively the ruling that knits a net first area area size and to beat the area of hatched second area big or small.
S2062, with the ratio of said first area and test pattern area, and the ratio of said second area and test pattern area in a bigger shape misalignment as said random figure and said test pattern.
Calculate the ratio of said first area and said test pattern area, and the ratio that calculates said second area and said test pattern area, get wherein the greater as the shape misalignment of said random figure and said test pattern.Can avoid when following extreme case takes place mistake to confirm said misalignment like this; As shown in Figure 5; The area of said random figure (polygon produces when triggering touch-screen by palm or face) is bigger, and covers said test pattern fully; Said like this first area is just bigger and exceed preset range, and said second area is 0.In fact at this moment the registration of said random figure and said test pattern is confirmed said misalignment if still get the smaller among the two then can lead to errors not within preset range.
S207 compares the area size of said random figure and the area size of said test pattern, when ratio is within preset range, and execution in step S208; When ratio exceeds said preset range, execution in step S209.
Wherein, said preset range can be 80%～120%, promptly said random figure can less than said test pattern, also can be greater than said test pattern.And the embodiment of the invention is not limited to make the area size of said random figure directly to compare with the area size of said test pattern.In other embodiments of the invention, also can use the area size of said random figure to compare with the area size of said test pattern with the difference of the area size of said test pattern.
S208 accepts said touch input, and carries out corresponding operating according to said touch input.
