Abstract
A touch device includes a touch panel, a sensing unit, and an operation unit is provided. The sensing unit is coupled to the touch panel, for scanning a scan area of the touch panel to output a touch signal. The operation unit is coupled to the sensing unit, for determining the scan area according to the touch signal. When the touch signal corresponds to a first close path, the operation unit defines a close area formed by the first close path as the first sub touch area. When the first sub touch area is undefined, the operation unit chooses a whole touch area of the touch panel as the scan area. When the first sub touch area is defined, the operation chooses the first sub touch area as the scan area.
