1. A method of determining input pattern, adapted to be implemented on an electronic apparatus equipped with a touch panel and comprising:

  • detecting a plurality of boundary points of an input pattern inputted through the touch panel;

    defining a first polygon having a plurality of sides and each side of the plurality of sides of the first polygon being a tangent line of one of the boundary points respectively, so that the input pattern being surrounded in the first polygon;

    defining a second polygon having a plurality of sides and each side of the second polygon extending between one of the boundary points and another of the boundary points, so that the second polygon being surrounded in the input pattern;

    detecting an area ratio of the second polygon to the first polygon; and

    determining the shape of the input pattern at least according to the area ratio.
