Claim 3:
4. The touch sensitive processing method of claim 2,
wherein when the shape of the report area is a circle, the determining whether the approximating or touching position is within a report area comprises:
calculating a first function value (x−Cx)2+(y−Cy)2, where coordinates of the approximating or touching position are (x, y), a center of the report area is at (Cx, Cy);
calculating a square value of a radius of the report area;
comparing the first function value with the square value of the radius of the report area;
when the first function value is larger than the square value, it is determined that the approximating or touching position is outside the report area; and
when the first function value is smaller than the square value, it is determined that the approximating or touching position is within the report area,
wherein when the shape of the non-report area is an ellipse, the determining whether the approximating or touching position is within a report area comprises:
calculating a second function value (x−Cx)2/a2+(y−Cy)2/b2, where a length of one of the major and the minor axes in parallel to an axis “x” is “a” and a length of another one of the major and the minor axes in parallel to an axis “y” is “b”;
comparing the second function value with 1;
when the second function value is larger than 1, it is determined that the approximating or touching position is outside the report area; and
when the second function value equals to or less than 1, it is determined that the approximating or touching position is within the report area.
