发明名称 System and method for determining touch positions based on position-dependent electrical charges
摘要 Systems and methods determine the position of a touch on a surface of a device, such as a touch-sensitive device, by using position-dependent electrical charges. In such a method, the position of a touching implement is determined on the sensing surface of a device. The method includes generating signals on the surface of the device to create a position-dependent electrical charge on the touching implement; and measuring the position-dependent electrical charge to indicate a coordinate on the sensing surface for establishing the position of the touching implement.
