Abstract: A touch type distinguishing method may be provided for a touch input device including a touch screen. The method may determine a touch on the touch screen. For example, a touch on the touch screen may be determined as an authentication touch when a condition that the time period for which the input touch maintains is equal to or greater than the predetermined reference time period is satisfied prior to the long touch determination criterion time point. The touch on the touch screen may be determined as a long touch when the condition is not satisfied.
