A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a touchscreen configured to display information and receive touch inputs; a sensor unit configured to detect a gravity characteristic of the mobile terminal; and a controller configured to output a user-settable gravity sensitivity threshold option for setting a gravity detected sensitivity of the sensor unit, to receive a selection signal indicating a selection of a first gravity sensitivity threshold, to determine the mobile terminal is in a state of falling when the detected gravity characteristic of the mobile terminal is less than or equal to the selected first gravity sensitivity threshold, and to automatically execute a predetermined function mapped to the determined falling state.
