METHOD AND SYSTEM FOR DETECTING A CONTACT ON A TOUCH SCREEN
First Claim
1. A method of detecting a contact on a touch-screen panel including a plurality of touch-sensitive units arranged on a touch-sensitive surface, the method comprising:
- receiving at least two induction signals induced by a contact of an object with the touch-sensitive surface at a point in between at least two adjacent touch-sensitive units, the at least two adjacent touch-sensitive units including a first touch-sensitive unit and a second touch-sensitive unit, the at least two induction signals including a first induction signal induced by contact with the first touch-sensitive unit and a second induction signal induced by contact with the second touch-sensitive unit;
combining the first and second induction signals to produce at least part of a touch signal;
processing the touch signal to generate a control signal; and
outputting the control signal to a terminal application device to enable user to view data from the contact point.

Abstract
A method of detecting a contact on a touch-screen panel including a plurality of touch-sensitive units arranged on a touch-sensitive surface. The method comprises receiving at least two induction signals induced by a contact of an object with the touch-sensitive surface at a point in between at least two adjacent touch-sensitive units. The at least two adjacent touch-sensitive units include a first touch-sensitive unit and a second touch-sensitive unit. The at least two induction signals include a first induction signal induced by contact with the first touch-sensitive unit and a second induction signal induced by contact with the second touch-sensitive unit. The method further comprises combining the first and second induction signals to produce at least part of a touch signal, and processing the touch signal to generate a control signal and outputting the control signal to a terminal application device to enable user to view data from coordinates of the contact point.
