1. A touch signal accessing method, comprising the steps of:

  • receiving a current touch point;

    determining whether a spatial continuity is smaller than a spatial threshold, the spatial continuity being a spacing distance between a previous touch point and the current touch point;

    determining whether a time continuity is smaller than a time threshold, the time continuity being a time interval between the previous touch point and the current touch point, and if the spatial continuity is smaller than the spatial threshold, and the time continuity is smaller than the time threshold, adding the current touch point to a temporary touch point set and accumulating a count value;

    determining whether the current touch point is a significance point according to the count value; and

    performing a touch point reporting procedure if the current touch point is the significance point.
