1. A method for improving link target accuracy for a mobile device with a touch-screen display, the method comprising:

  • displaying a page which includes a plurality of selectable text objects on the touch screen;

    defining a number of targets on the touch screen, wherein a respective target is associated with a selectable text object, and wherein defining a target involves;

    measuring a distance from a character within the selectable text object to a different character within an adjacent selectable text object; and

    marking the character within the selectable text object as the target in response to the measured distance exceeding a threshold, thereby resulting in the target being separated from other targets such that an accurate selection of the selectable text object is made by a tap close to the target; and

    indicating to a user that the selectable text object is selectable by tapping on its associated target.
