A portable device including a touch sensor configured to sense touch inputs, the touch sensor being in an active state while the portable device is in a standby mode; a touch sensor controller configured to receive the sensed touch inputs; and a processor configured to receive a signal from the touch sensor controller indicating whether the received sensed touch input indicates a first pre-stored pattern corresponding to a first active mode or a second pre-stored pattern corresponding to a second active mode, control the portable device to be in the first active mode based on the touch sensor controller receiving the signal indicating the sensed touch inputs correspond to the first pre-stored pattern, and control the portable device to be in the second active mode based on the touch sensor controller receiving the signal indicating the sensed touch inputs correspond to the second pre-stored pattern.
