<p>The present invention relates to a touch sensing system and a smoothing filter controlling method thereof. The touch sensing system includes: a coordinate calculation unit calculating coordinates for touch input; a smoothing filter compensating current coordinates using past coordinates inputted from the coordinate calculation unit, a first coefficient multiplied to the past coordinates, the current coordinates inputted from the coordinate calculation unit, and a second coefficient multiplied to the current coordinates; and a smoothing filter control unit adjusting the influence of the past coordinates and the influence of the current coordinates in the smoothing filter by varying the first and second coefficients of the smoothing filter.</p> |
