Abstract
A multi-touch sensing system and a method for estimating a location of at least one touch point are provided. The multi-touch sensing system includes a panel, a grid of conductor disposed on the panel, a driver array connected to the grid, a receiver array connected to the grid, a signal processing system, and a controller. The method involves transmitting drive signals to the grid, receiving signals from the grid, estimating a capacitance, and transforming the capacitance into touch coordinates.
