Abstract
A touch sensing system including a touch interface and a processing unit is provided. The touch interface has multiple independent touch blocks. The processing unit is coupled to the touch interface. The processing unit includes an interpolating unit. The interpolating unit interpolates multiple spacing points between two adjacent touch blocks along a first direction to generate multiple first coordinate values. The processing unit determines a central block according to a threshold value and sensing values corresponding to the touch blocks, selects at least one touch block adjacent to the central block as a peripheral block, and determines a touch position on the touch interface according to the number of the spacing points, the sensing value corresponding to the peripheral block, a position of the peripheral block, the sensing value corresponding to the central block, and a position of the central block.
