Link target accuracy in touch-screen mobile devices by layout adjustment
First Claim
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.

Abstract
One embodiment of the present invention provides a system for improving link target accuracy for a mobile browser with a touch-screen display. The system receives a page with a plurality of selectable text objects and adjusts the page layout. The method further includes placing a number of targets within the web page. Each target is associated with one selectable text object, and the selectable text object can only be activated by the target. The targets are sufficiently separated from each other, thus allowing a user to hold the touch-screen display and select the selectable text object by tapping on the target with substantial accuracy. Another embodiment of the present invention allows a user to select a selectable text object by performing a gesture.
